GURU's official LS/B5 Quattro Swap for under 5k

[GURUMAN]

Title says it all [:D]

Having stage 4 power and torque for less than half the price.

Dont get me Wrong guys, the 996T is still in plans for Feb or March.

Since I cant use the Porsche to go to my clients, I dicided to transform my old rolling chassis (the satin Black B5) in a 450 hp + DD[>_<]


IF A VR6 fits, the LS will[;)]

god that's beautiful

[NYCVR6]

Haha love it.

[JDM EJ1 95]

we actually had this idea as well.. and had the motor and our a4 chassis.. LS is a lot longer than a VR6.. we measured an LS with as much removed on the front of the motor as possible and youd have to run either a modified front support, or no stock front support at all.. or do some cutting to the firewall/strut crossbrace

it is definately a sick idea though.. quattro LS1 would be a mean setup.

[S4 Dan]

haha, you are the man!

[GURUMAN]

This is not my engine, it's jus to show you guys the adaptor exist in the kit car world...

Mine will look like this one

x2 looking forward to :
1. seeing if they let you keep this on here this time (vendors should get upset over this they don't even produce this).
2. the end product and power you make.

either way good luck with it and keep us posted [up]

[GURUMAN]

http://www.currentperformance.com/Harness_4ft.JPG

Custom harness is around 500$ to 600$

You fit the Stock ecu on it that comes with the engine...

[awtst3.a6]

If one man can do... guru can. Even if the LS doesn't fit I am sure he will make it work :D. GL with the build guru

[GURUMAN]

I will probably push the rad a bit more front, and put an universal aluminium 3 row GM rad
200$

[hercfe]

If an LSx can fit in a STI, it will surely fit in a B5 chassis. This should be pretty interesting for sure!

[antoanS4]

everything is possible with Guru

[Kruat]

Sweet build, hope certain people don't get involved and get the thread closed. Which LS are you looking at doing? Retaining AWD via audi 5000 tranny? Sounds sweet. Good luck.

Audi S4 01e 5 speed tranny from 96 S4. With full quattro system that went 10 sec[;)]

[onemoremile]

Keep the kid stuff out so we can keep this thread open. I love this stuff.

A 350 fits nicely in the B5 and I doubt the Ls block is any larger externally. The only issue I can think of is the water pump and belts but you can run a shortie electric and cut that length down.


as far as the wiring harness goes, well here it is

Other than that, i really havent been driving it lately, the weathers been sh*ty around here, so sorry no vid yet, im workin on it.

Since everything is finally runnin good, besides a little coolent leak, Im finally cleanin everything up. Ive been pretty busy with school so I really wasnt playin in the garage, but I just finished my last final today and Im off til Jan. 19th. Now hopefully the last bit of progress that needs to be made will get finished

Never thought I'd see this on an LS. [:D]

I thought putting one in my Miata would be badass. [:p]

[Coopa]

Watching this one for sure.

[8520]

Not a fan of crossbreeding, especially when using carb'd motors, not that guruman is going that route.

[GURUMAN]

Agreed with your point, I'm certanly not gonna go back 20 years in technology.

My car will have the Ecu system from the Corvette, witch is 90% standalone by itself.[;)]

[GURUMAN]

The only standback in technologie in my project will be still the drive by cable conversion, but hey, My S4 project was already this way with the OE engine.

[Trigger Happy]

GURU seeing a big displacement power-plant in an S4 makes me feel all warm and fuzzy inside. I love the LS series. After owning an 06 GTO I think the LS2 is my favorite engine of all time. It sounds amazing, looks amazing, mad torque down low, ahhhhh! I want this. So excited to see how this turns out. Please please please keep us updated on the final cost of the project I feel like this could be a viable alternative to stage 3 and up power. Ur awesome GURU!

[antoanS4]

Sold my 6 speed to dla79

It's as strong as yhe 6 speed...

[antoanS4]

but the B5 S4 tranny would fit too rigth?

[GURUMAN]

but the B5 S4 tranny would fit too rigth?

Ya man, casing is the same.

The kit will provide:

Adaptor plate, billet aluminium.

Custom Flywheel

Audi 200 clutch and pressure plate

Custom starter

Will fit any LS series... even LS9 [evilsmile]

[Mrsfourrings]

Guru any plans down the line for a remote turbo system (ie... STS)?
By the way Eric is a good guy! I talked to him right before Thanksgiving about a similar set-up.

[antoanS4]

Im going to be sooo happy if you can fit a BAT in there somewhere, even twins would be awesome. A remote turbo or turbos would work too but idk... I've heard a lot of mixed reviews about the remotes.

[Dowskeet]

This will be interesting.. Make some gear heads turn their heads when they pull up to this car. Goodluck Guru

[skele4door]

I will probably push the rad a bit more front, and put an universal aluminium 3 row GM rad
200$


Just FYI GM changed the sizes of the inlet/outlet between the SBC and LSX. You'll probably need to use some adapters to adjust hose sizes if you use one of those generic aluminum Camaro rads. I'd suggest looking into Howe radiators. They are only slightly more and if you find one of their off the shelf rads that will suit your needs they'll adjust the inlet/outlets for a small fee. Also make sure you don't hard mount the rad to the chassis. Aluminum radiators don't like dealing with chassis flex too much.

[TravS4]

Aluminum radiators don't like dealing with chassis flex too much.

Hopefully you didn't find this out the hard way [:(] lol

And Guru, any idea on tuning plans right now? Are you going to go searching for a good LS tuning or going to have some custom stuff done from the same people that did your GT setups?

[Scotty@Advanced]

that's nice to see pictures! Eric Martin is always asking me questions about 01E transmissions and clutches, it's nice to see his work. Next time I'm further North I need to pay him a visit.

The stock 200 quattro clutch is marginal with that kind of power.

[csre9]

[Rated S]

whats the best LS motor?

LS1 is the most common engine which came out of a lot of GM cars. Camaro, Trans Am, Corvette, etc.

[kiellish]

wow awesome build. how is this going to affect the balance of the car?

[AudiVWTech]

wow awesome build. how is this going to affect the balance of the car?

not at all really. If anything it will improve balance. The long blocks weight the same. But now you are pulling the intercoolers and piping out of the nose. All said and done it will probably weigh the same or a little bit less with the balance practically unchanged.

[will175]

Wow very interesting. I like the price point too,lol. Do you think a remote (like STS) mount turbo work in the swap? That would be sweet set up also with AWD. You crazy man you. And there are some crazy deals on 996 turbos right now, which you prob know.

[2kblacks4]

I love this idea! Keep us posted.

[lrg8683]

TT it get 600whp out of it.. call it a day.


lol.. i joked about an ls1 swap 2 or 3 years ago.. didn't even think it could be possible.

[TravS4]

And there are some crazy deals on 996 turbos right now, which you prob know.

I have a feeling he already cashed in on one of those deals [;)]

[Raacerx]

Have to admit, pretty cool. Next thing you gotta do though, is deal with the engine-in-front of of the front axle bullshit. I want to see an S4 with near 50/50 weight.

[washyourrhands]

this is awesome!!! nice work and please keep us posted with step by step pictures or your build and progress. Kudos!!!

[MAKK]

now THAT would be sweet

Agreed.

My shop mainly deals with muscle cars, and I can tell you that this setup will be vicious on the street when done. Just think what he can do power wise with a Whipple or Kenne Bell on there...[evilmad] I think you'd still be around the same price as a Stage III kit, lol.

[sweetsound2001]

So this kit will have a turbo LSx motors bolted up to an Audi awd transmission and retain all the stock amenities, (ac, power steering, etc)?

And the cost for the complete conversion? [o_o]

[GURUMAN]

I'm not decided between LS1 or LS6

Ls1 is 1500$ Vs 2500$ for the Ls6

Fabing a turbo kit with a used gt40 will cost about 2k

I might go strait to remote single turbo that would be placed where the first resonator goes driver side...

That would give about 500 whp at 7 to 8 psi [:D]

[sweetsound2001]

That would give about 500 whp at 7 to 8 psi [:D]

Right!!! Like you're gonna leave it alone at 8 psi [wrench]

[S4_NE]

Good luck man, I come from the SB Chevy/Ford world before I went to German cars in 2000, This makes me miss them some times, Hope all come together for you well.

[MikeyB3]

Guru, you inspire me.

[emenny81]

Im interested.

[DaveS4]

Hot damn, this is going to be ridiculous.

[wdbdy2000s4]

TT it get 600whp out of it.. call it a day.
It's a waist of time to twin turbo that motor for 600whp. a LS1 with a 40R will spool like K03s and make 600whp with less than 10PSI.


Right!!! Like you're gonna leave it alone at 8 psi [wrench]
8 PSI through twin k04s on a 2.7T is far different than 8PSI through a 40R on a 5.7L. 8PSI is enough for around 600whp with that setup.[evilsmile]

[lrg8683]

i'm all about the single turbo..i figure, space wise, 2 smaller turbos would be easier to fit in... though if it's going to be a remote mount single then it doesn't make a difference..

can you still use AC,power steering and all the other stuff?

[GURUMAN]

Now before anybody tries to discourage me to go remote, watch this...

The remote oiling setup, I have it already from Mike Rombotis, it's from a 911 Turbo...

http://www.youtube.com/watch?v=p-BMmv7J-9k

[antoanS4]

LS1 is the most common engine which came out of a lot of GM cars. Camaro, Trans Am, Corvette, etc.

performance wise, which one is better LS2 or LS6,i dont know anything about Ls motors thats why im asking,i have heard a lot about the LSX motor which one is that one?

[GURUMAN]

I got my hands on a very cheap LQ4 witch is perfect for Force induction 10 psi...

IT's from the silverados, same as ls2 6.0L but iron block. CR is 9.3 to 1 instead of over 10...

It's about 85 lbs heavier, but I will add about the same in the back so I couldnt care less...

[koolkoreanked]

performance wise, which one is better LS2 or LS6,i dont know anything about Ls motors thats why im asking,i have heard a lot about the LSX motor which one is that one?

Ls6 cause it's built from the factory, tho one could argue the ls2 has more ci. Seat of pants feel and local races back a few years ago says stock for stock the ls6 is faster than the ls2, tho that could be because the c5 z06 is lighter.

Even though I mentioned I'm not a fan of crossbreeding, I wouldn't discourage you from doing it.

[Vinny@DTH]

Hey Dom! look at what I just get in the garage to get the engine out ;)

http://i211.photobucket.com/albums/bb10/SHERIF222/siilverado.jpg?t=1261595454

lol 2000 Sierra 2500 with your 6.0l LQ4, I have some others but this one is running and wasn't scraped because of a crash but because some guys did broke-in the Cantine box lol

[americanthunder]

Ls6 cause it's built from the factory, tho one could argue the ls2 has more ci. Seat of pants feel and local races back a few years ago says stock for stock the ls6 is faster than the ls2, tho that could be because the c5 z06 is lighter.

They are a toss up, the LS6 has a more aggressive cam and sodium filled valves, and a better intake manifold the LS2 has more cubes. I had a 2005 Gto (LS2) my best friend had an 04 CTS-V (LS6) we raced a few times and hands down the LS2 wins down low, up top I say LS6 cause of the more aggressive cam. The c5 Z makes the LS6 look really good, but thats what happens when the car weighs 3100 or less with the very aggressive gearing. Guru if your going to boost it I agree the LQ4 is great for boost! I had a boosted silverado before and the LQ4 was the motor to have. The LQ9 would be another option it has a bit more compression than the LQ4 though it came in the cady SUV's and the Denali's. All depends what you wanna do with it. I vote LS7 though it will for sure break your budget [:D]

[will175]

Just curious how much is a LS7? New or used?

[americanthunder]

Just curious how much is a LS7? New or used?

I think they go for about 12k from gm brand new.. I think. I know the LS9 is closer to 20k [o_o]

Woohoo. Thanks bud for the answer. Some money right there.[:D]

[GURUMAN]

Who needs ls7 when you can hae more power for less...

Here is 550 whp at 8 psi on pump...

LQ4 1200$ with ecu
custom harness 500$
T70 turbo 900$
custom eshaust 500$
charge pipe 200$
tune 300$

[TravS4]

Also, the LS7 has high compression which is why GM went with the LS3 block for the LS9. And because there's a bit more space and strength between cylinders.

[AWD87]

LS in a S4?! Pretty badass idea [up]. I always wanted to see that. Keep us updated

[blackedoutb5]

nice to see some more stepchild crossbreeding between american and german [:D] Keep it up, I wanna see how the front end fits, it was tight for me...

Somebody can correct me if i'm wrong, but I believe the Ls1 block is the more desirable one for forced induction. Try to get an 01+ LS1, I know the older ones had an issue with piston slap. Some of the later model LS1's also came with the Ls6 block


performance wise, which one is better LS2 or LS6,i dont know anything about Ls motors thats why im asking,i have heard a lot about the LSX motor which one is that one?

LS2 is newer technology, it's the generation after the LS6. You can buy GM L92 heads for the LS2 for about 1k for the pair, a decently sized cam, and you're on the fast track to 450+ whp n/a. It's a beast of an engine.

Yup, I decided to sacrifice the Na stuff to get a simple cost effective remote turbo system.

I already have my FMIC / BOV

Oiling system

Custom exhaust (I have to make anyways)

Charge pipe will go inside the car.

These ecu's are so easy to play with, it's crazy.

LSX

[AudiVWTech]

i did some measuring tonight. Looks like there is 20 inches from the transmission to the radiator shroud. the LSx needs 24 inches with the shortest accessories off of an LS4. With the radiator pushed forward a few inches and some slim fans I could see it working out. Also probably going to have to put the intake manifold on backwards and run the air intake by the cowling. LS4 engines are pretty available. Theres a couple on ebay for around 1500 bucks and LKQ also has them starting at 1000 bucks.

Thats so rice [>_<][:D]

[jrock]

May seem rice but the LSx engines are like most engines where they need to vent the excess oxygen rather than redirecting it back to the engine. I am sure you could do it with some sort of fab work but I only see problems when using a dv with an ls engine just like using a bov on an audi.

[shorterthanrich]

yes.

[DannyLo]

i must say...i can't wait to see this marriage!

I thought you were joking...

BUT, I approve. IIRC the manifold can't be mounted backwards though. It's been like a year since I played with an LSx though.

My LSx buddy (the guy who taught me what I know about them) is now shoehorning an L33 (all Alum 5.3L with LS6 cam) into his Miata.

I'll keep checking back on this thread.

[wrench]

truth. The C5 ECU flashes in 1/4 the time of the F-Body ECU too.

[AudiVWTech]

The manifold can be mounted backwards on any LS motor. The kit car guys do it all the time. The heads are indentical (they can be mounted on either side ot eh motor) and there are no coolant hoses or passages connected to the manifold. It's been done many times

The GM ECUs are all the same. The ECUs are only different in the software that is on them. You can take an ECU out of a truck and flash a camaro tune into it and throw it in a camaro plug and play. So it does not matter what ECU you end up with.

You can swap the intake mani and have it point backwards. You just need to do the same thing with the fuels rails and coolant crossovers.

Any ETA on completion?

I might have to follow suit and do this after you. I was going to try to sell my S4 this winter but after seeing this I think this is what I want to do

Yea, I realized that later. I remember somebody talking about it awhile back.

The ECU's are not identical. The '02 F-Body ECU only uses about 60% of the pins in the ECU connections, VS the C5s, where they use about 95% of them.
I've flashed both from the same laptop with very similar files, and the F-Body ECU literally takes 4x longer to re-flash.

The ECU's are not identical. The '02 F-Body ECU only uses about 60% of the pins in the ECU connections, VS the C5s, where they use about 95% of them.
I've flashed both from the same laptop with very similar files, and the F-Body ECU literally takes 4x longer to re-flash.
Oh. I guess I never payed attention to the flash times. But as far as the actual tuning goes and compatability, it doesn't matter what ECU you end up with, although, if you are using a truck harness, you have to use a truck base tune. You cannot hook a corvette ECU to a truck harness and tweak the tune, the tune has to start as a truck tune, but you can than copy the table from the corvette tune and paste them into the truck tune. Between the different cars and trucks that used these computers and harnesses for the LS motors, they were assigned different pin locations on the ECM, thus making it not possible to just plug a vette computer into a truck harness, without first flashing a truck tune into the computer.

I hope that made sense. Also some other things to consider when buying this stuff used:

If you want to use the drive by wire setup, make sure you get a harness that is wired for it already along with a ECU that has the pins in the corresponding spot on the ECU. The trucks were drive by cable till 2003. THey then switched to DBW. The F body's were all drive by cable. All vettes are drive by wire. All GTOs and G8s are dbw.

Another thing is that there is a GEN 3 and a GEN 4 LS motor. The Gen 3 motors have a 24 tooth reluctor wheel on the crankshaft whereas the gen 4 motor is a 58 tooth I believe. LS1, lq4, lq9, lm7, and the 4.8(whatever designation that is) are all 24 tooth motors that must use a 24 tooth computer and harness. The ls2, l76, 92, ls3, ls4, ls7, ls9, ll7, bla bla bla, are all 58 tooth motors with different style knock sensors. And most of those motors have wider angle rectangular port heads (ls7 style) making the earlier intake manifolds non interchangeable.

Theres a bunch of other small differences, but those are the main ones.

[davenew]

Have to admit, pretty cool. Next thing you gotta do though, is deal with the engine-in-front of of the front axle bullshit. I want to see an S4 with near 50/50 weight.

Easy.. he can throw a spare S4 engine in the trunk. Done!:)

[davenew]

They are a toss up, the LS6 has a more aggressive cam and sodium filled valves, and a better intake manifold the LS2 has more cubes. I had a 2005 Gto (LS2) my best friend had an 04 CTS-V (LS6) we raced a few times and hands down the LS2 wins down low, up top I say LS6 cause of the more aggressive cam. The c5 Z makes the LS6 look really good, but thats what happens when the car weighs 3100 or less with the very aggressive gearing. Guru if your going to boost it I agree the LQ4 is great for boost! I had a boosted silverado before and the LQ4 was the motor to have. The LQ9 would be another option it has a bit more compression than the LQ4 though it came in the cady SUV's and the Denali's. All depends what you wanna do with it. I vote LS7 though it will for sure break your budget [:D]

You can buy LS9 crate engine for around $19k.

[sCeRaXn]

Theres a guy local to me(sorta) that has an lq9 in an fc rx7. Those are the same things as lq4's just with flat top pistons(10:1cr i think) and a different intake, correct? If so then that will be a beast of an engine and respond really well to mods. Hes still all motor with a few minor bolt ons and hes putting down mid 400's. Good luck man!

Yes it is, just came as the HO version in the truck Vortec engines...

[Caddy7]

How is the tune done? Someone mention 90 standalone, is there a good software for homebrew tuning GM?

[AudiVWTech]

HPtuners and EFIlive are the two premier software programs for tuning GM vehicles. They allow you to change just about anything you want in the ECU giving you pretty much standalone style tunability.

Just FYI the LS6 instake will not work with L92 heads. If you plan to move to those heads you'll either need to get an L76 intake or something aftermarket. Just making sure you don't waste money buying things twice.

For future reference. If you want to stick to the cathedral port heads you can pick up a set of worked ls2/ls6 heads from Texas Speed. Those are the 243 and lesser known 799 castings. They are a great company and offer a ton of stuff for great prices. The heads they offer are worked over by them but the heads are labeled as Precison Racing Components. They are a cheaper alternative to all out heads from AFR.

[AudiVWTech]

The only thing that is gunna stink is the top gear revs on the highway. I dunno what the top gear ratio is on the 01E 5 speed, but the 6 speed is 3000 rpm at 75 mph. Thats a little much for a big v8 in my book. With a Diesel 6th gear swap though, revs would be more reasonable. The 6th gear gearing on the T56 transmission in F bodies and Vettes keeps the 75 mph revs at under 2000 rpm. I don't think we can get that far down with the diesel 6th gear, but the closer the better.

Do you know what rpms would be if you were to source an DRW/ERF TDI 6 speed trannys from europe??

here is the data on it...

Final: 2.129

I suck at doing the conversion to understand the speeds at certain rpms... if someone could post it up..

or if someone can find more info on the new KMR transmission in the 2010 Audi RS6/S4 's says both use the same manual gearbox and if that is true something is beefed up in them to hold the power.. and the stock clutch would be able to handle the LS motor torque and keep the rpms down...

IMO, If your really depressed about that 6th gear, get the just the gear From JHM, but keep all the others

The fianl ration from the S4 is 4.11, if you dont want to have to change diff too...

[AudiVWTech]

yeah, you can't swap the whole transmission out without changing the rear end out. I like the stock S4 gearing, I would just do the 6th gear swap. The JHM 6th gear units are a little pricy, but I think for a daily driver would be worth it.

[NYEuroTuner]

Same here. I've got a spare set of 243 heads.

[up][up]

I vouch for mike, he grew up on American muscle, and he has built and is currently building some pretty sick Domestic cars/motors. Dude has a pretty impressive stable IMHO.

[skele4door]

The most common T56 6th gear is .50:1. I'm running 4.10s in the RX7 and it works fine, but a numerically lower gear ratio would probably be a bit nicer since you can really lug these around at low rpm. I'm sure you'll be fine with the TDI 6th gear on the highway.

[Storx]

i think if i do this swap.. im going to source an cheap yet somewhat valuable car/truck with the desired engine.. but has parts on it.. that could be resold for offset cost.. there are a ton of cars/trucks on craigslist around 1k with LS motors.. that would supply you everything.. even a baseline wire harness to swap over if wanted to...

LSX have a 4 cylinder signal and looking through HPTuners I don't see any easy way to add a modifier and fool it into outputting a 6 cylinder signal. You might look into Dakota Digital's SGI-8. I don't think our gauges use a CAN bus, so it should be what you'll need.

BTW, I forgot to mention that you might want to swap some upgraded rod bolts and oil pump into your engine before you drop it in. The stock oil pumps have been known to randomly fail and the rod bolts are pretty marginal when you start making some decent power.

Sweet... Even if everything else works it wouldn't be a huge deal to use an aftermarket tach. There are some pretty sweet ones out there and they'd be even sweeter if they matched the S4 cluster lighting

You can recode the cluster to run off a 4, 6 or 8 cylinder signal so you don't need to fux with it in HP tuners. [;)]

and I'm pretty sure it's not using CAN bus like the later model cars either.

not trying to step on your toes man.. just wandering what you are planning for in the end result???
I have been doing a lot of studying and this is what i have come down to for ideas for the different motors...

LQ4= is nice stock setup if you plan on boosting (9.4:1 300hp Iron). can take up to around 600 crank horsepower easily without crank swap. Common swap on these is to run LQ9 heads with magic cam 4.
Issues: crank not forged and seems to be the weak point in these engines and head bolts tend to crack under anything more then stock HP...

LQ9= is nice stock setup if you plan to run N/A (10.1:1 345hp Iron). can take up to around 600 crank horsepower easily without crank swap before 2003. After 2003-2004 it was switched to an 23gram stronger forged rod w/forged crank so this is the desired year which has been proven to hold over 1000+hp.
Issues: Pre 03 crank not forged and seems to be the weak point in these engines and head bolts tend to crack under anything more then stock HP...

LS1= Is nice stock setup if you plan to run N/A (10.1:1 350hp ALUMINUM 305hp Iron). both are good up to about 500-550hp easily stock without any internal failure. Common swaps are Magic cam 4, LS6 heads and PPE 249.95 set of 8 ebay forged rods. Seen more then 10 built engines running these dirt cheap rods pushing at or over 1000HP at the wheels..on the forums when asking around for info.
Issues: rod bolt failure is common after 550hp on stock internals.

If you want to throw in more stuff go ahead.. this is just a collection of everything i was told by people who built these engines on the forums.. and through threads i read.
Oh ya the difference in weight between the Iron ls1 vs Aluminum ls1 is 73pds when stripped down to block, head, and intake manifold.

[Storx]

Here is my list of mods and engine choice i think i will go with:

LS1 Aluminum 2001-2007 version

Texas Speed Magic Stick 4 Camshaft 374.99
LS2 cylinder heads 325.00 pair from GM dealership re-manufactured

Yeah I think you might be missing some of his mods. Nobody puts down 541 at the wheels with stock compression, stock LS6 heads and an agressive cam. He's probably got a small shot on there as well.

If you want to throw in more stuff go ahead.. this is just a collection of everything i was told by people who built these engines on the forums.. and through threads i read.
Oh ya the difference in weight between the Iron ls1 vs Aluminum ls1 is 73pds when stripped down to block, head, and intake manifold.

Thanks for the info, i guess i will be looking for a LS1-2 then. I dont know if i'll cheap out on the rods but i might you never know lol... I want to keep it n/a for a bit as adding a turbo will be an extra cost that i dont have. Having 8-900awhp in the audi will make it a insane monster.

[zerb]

what are everyones thoughts on the drivetrain staying together with these motors? i know they handle the power of the s4 motor, obviously GURU can attest to that, but these ls motors are a whole nother animal no?

[wdbdy2000s4]

I think they'll be fine. We very rarely have seen people blow up drivetrains. It's very rare to find an issue with the Diffs caused by anything other then weak mounts or the crossmember, both of which are easily upgraded now. The s4 trans has held pretty much anything thrown at it(with the exception of weak shift collars, but those are also upgradeable). That just leaves axles, but you will need a turbo LS and some hard launches to start snapping those and at the point you can just go solid.

[GURUMAN]

Band for the buck, Lq4 block from silverados, tahos are about 1k

I dont want anybody to think the ls1 or ls6 in anyways represents better alternatives.

Yes for a crate engine, but if you plan to open or turbo the motor, go for the cheapest engine.

[NYEuroTuner]

Ok so im selling my Vr6 and going to buy a LSx, Which ever local deal i find i will buy it. But i really want a Lq4 or lq9. Having 400-500 N/A AWHP is going to be straight monster with the quattro traction....

Giving up so soon? lol

yes i know you say that when you look in junk yards. cherck out the forums that trade and build ls1's... you will see peeps selling engines for less then 1k easily. if you go on craigslist and look up vehicles that carry ls1's you will find alot of therm for really cheap. on ls1 forums you see part outs and find blocks and engines really cheap....just have to look....


-99/00 LS1 ALU stock block w/ internals 133k $300 (ls1tech classifieds)


used LSX block needs machining $200 (hardcorels1 classifieds)


used ls1 block $75 (ebay)



new ls1 block $725 (ebay)

you just have to be patient and look.. there out there dirt cheap... heck i ask a few friends i knew from local dragstrip and one of them knew someone with an ls2 block sitting in his garage that i could just have needs bored out with custom pistons because cylinder damage...but told him i take it...if anything i might use it if cant find a good usable block without needing being bored.......

[GURUMAN]

Vr6 swap is a whole other animal...

But you got to rember you start with a 200 hp engine compared to a 350 hp engine for about same price even cheaper...

A question to you is are still able to run a conventionnal fan or you have to switch to a pusher type ?

[djwimbo]

I dont know if i'll cheap out on the rods but i might you never know lol...

We ran SCAT rods in the LS1, and they're strong enough to handle a 150-250 shot of N20.
Through a C5 Z06 trans/diff, we did 425whp with the following.

Mahle 3.905 pistons, SCAT rods, hand ported and milled heads (~12.0:1 CR), G5 cam, lightweight and underdrive pulleys, lightweight valves/retainers/springs, FAST intake (with direct port) ... and the little things, like homebrew tuning (yay HP-Tuners), Z06 coils, better wires, hand ported throttle body, etc.
The time and effort was spent balancing the rotating assembly. My friend did it at the school, and he balanced the crank within 0.03grams of "perfect".

N/A, reliable, and built for like $2200? Yea, that was a fun car.

[GURUMAN]

It's all a matter of preferences, me instead of paying 1500$ + for heads and cam combo, I prefer running 8 to 10psi on stock heads, block and stock ls6 cam

[djwimbo]

that is the beauty of the LSx scene. You can get good stock cams used for like $50.

They don't perform like a good lumpy cam, but they are great for the sleeper sound. The problem with big cams is that they need higher RPM to actually do much, and you lose low end torque.

[GURUMAN]

I think I will wait to se the condition of my engine before deciding to forge it...

People have seen 600whp + on stock lq4's only with ls6 cam and ls6 valvesprings...

These LS engines are crazy, It's seems endless the power thay can achieve...

dont forget the ls2 heads arre the same as the ls6 except the expensive sodium filled valves.. actually i read there better if you plan to run force induction over trhe ls6 because the ls6 heads are hallow and cant hold to the heat.

here is downloads charts of the complete engine wire harness of the ls1 in an corvette.. i was reading that is practically the exact same diagram on all ls1's except transmission/smog changes which are no big deal...these links were what most of the solstice ls1 guys went off of when doing there swap. apparently from what i read is that our stock audi cluster speed/rpms should work.. but might be just slightly off... but should work...

hey make sure you do some good DIY please for this conversion.. as im going to be going the same route when i get back from being deployed with the military.. haha.. im actually getting sent to Menwith Hill, UK when i get back from this tour.. so i going to be trying out an TDI tranny if i can find one decent.. but im going to taking leave for 30 days when i get back.. throwing an LS engine in my Audi A4 to take to UK so i dont have to worry about shipping parts from US to UK when i get there.. i am probably going to start buying some of the parts and have a friend in the states that i talk to.. start putting the engine together.. and have it ready to be installed.. or better yet.. if i can talk him down on labor.. maybe have him install it and wire her up..

Ya but for under 500$, I will order one, I'm not the type of guy that will bust his ass to save a couple of hundreds...

As for DIY, I manage and desing 90% of my projects.
As for welding, assembling engines, electrical work, I leave this work to professionnals.

To much trial and error after all these years [;)]

I'm designing my own remote half way turbo system, that acording to my calculations should spool and perform 90% of if It was placed up front.

I decided to spend a max of

engine 700$
custom harness 500$
cam/springs 350$
ls6 intake 400$
Turbo 400$
custom exhaust 500$
wastegate 250$
tune 300$
Adaptor + clutch 1600$

5000$

Stuff I had in car from previous build:
fueling, dual walbro inline + fuel cell
custom intercooler FMIC
tial BOV
Dual widebands + display podi
Boost guage + logger


In theory, I'm good for about same power I had in my previous 30K setup

[GURUMAN]

And I think the best part is this setup will never go over 12 psi !

And off boost, I have around 350hp and 340 ft/lbs witch is a lot more than the 2.7, 3.0 V6,VR6, L5...!

i hear you man.. but i want to go with the stock ls1 compression ratio of 10:1 because i would like to have more efficient off boost power.. as well be able to run less boost then you for the same power or similar power while on boost.

I have a good friend who is really good engineer that i worked with back in North Carolina when i was stationed there that is giving me the free ls2 block he has a really sick Turbo Malibu that he drives daily... and there this really cool fuel setup that i always wanted to try on my 2.2L Audi motor.. but never got around to it.. He hasn't updated his site but he recently updated the setup were he is running off 87 octane off boost and E85 when under boost instead of 116. He got the idea from the motorcycle world when they started to come out with 2 sets of injectors for low-end and high-end because once you reach a certain size injector you start to loose low-end power due to the atomization of the injector head when under low cfm rates so the smaller injector is able to be tuned for much better response and power lower in the rpms and off boost....
But after installing it he tuned it to where he could run lower octane like 87/85 when out of boost for normal off boost driving to not spend all the money on 116 octane at the time to drive the car daily to work.. 45 mins as he did from the base for work. then when he wants the power.. he punches it and it switches injectors at certain boost to allow for the power of running race gas every time you want to. he has logged over 100k+ miles off the 87/116 idea and has recently reached over 10k+ on the 87/E85 new setup..he would run E85 full but there is not a normal station that sells it near our town in North Carolina yet.. so he uses it at cheaper alternative race fuel over 116 when he goes out of town and picks up a few tanks of it to bring home...
the E85/116 is used in a 5 gallon fuel cell and lasts about an month to 2 months depending on how often he floors it..

True, but how many Cylinders, how much gas is burnt, and how heavy is the LS6 compared to the motors you've just listed?

[>_<] [:D] [:p]

Ls6 is about 40 pounds more than the 2.7... Vr6 I dont know ???

So my Lq4 will be about 100 pounds more than the 2.7...

Plus the turbo will be in the back where the first resonator use to be...

[GURUMAN]

And for the cylinder war, this I really couldnt care less, My other car audi B6 is beeing swapped with a 4.2L at this moment...

Lets just say I'm a fan of the V8 sound.

Whats the chances of passing emissions through an obd2 check out here in co with an lsx?

[Sscott09]

defiently considering doing this. I want a detailed log of this build before I start though.

[Storx]

Whats the chances of passing emissions through an obd2 check out here in co with an lsx?

they make the ecu give all passing emission codes like they do on our VW/Audi motors.. the only difference would be the physical inspection.. i know you can retitle a car when you change an engine out as long as the engine is newer then the original car year.. so for example buddy of mine bought an Audi A4 and put an 3.0L V6 TDI engine from Europe in it and had the title redone by the DMV with the new engine specs.

not a problem bro.. i have a lot of extra time on my hands while deployed so i am trying to do the homework to make this as little painful as possible for when i get back to USA...

I was surprised that the LS1 is literally the same weight as the Audi S4 engine.. the one that i found the weight on.. was weighted without the turbos but with the manifolds on the engine.. so once you add the weight of the turbo's you are looking pretty even trade for weight..

Check this out.. i was talking to a guy who was PMing me on LStech on telling me to run the LS4 engine.. i didnt know anything about it so i looked into it more.. found out some interesting facts.... He has one swapped into his Fiero and said that its a killer compact engine.. so i asked him for the weight.. and my eyes were shocked.. so i asked him for more info and if he knew which cars and trucks it came in...

he said the LS4 uses the LS6 light weight aggressive cam/valve package for weight saving.. so its compatible with any LS series cylinder head parts..
He said there is 2 other models that are all aluminum vortec 5300 engines...LH6 and LC9 which uses a lesser aggressive head package with a Power output of 285-295 hp and torque is 325 lb to 335 lb but weight is increased to 401pds.

[Storx]

The Iron Block version of the 5.3L weight is 458lbs he said...

here is wiki data for this motor since he said its not the preferred engine he didn't have much info to tell me on it..

And for the cylinder war, this I really couldnt care less, My other car audi B6 is beeing swapped with a 4.2L at this moment...

Lets just say I'm a fan of the V8 sound.


I have not heard much about turboing the 4.2L, is there limitations to that engine that I don't know of or why aren't there more turbo B6S4's out there?

[Storx]

give you some ideas of what the LS4 is capable of under little bit of forced induction..

I looked into using the LS4 engine but it will not work with the current transmission adapter plate that is available. The LS4 uses the GM front wheel drive bellhousing bolt pattern and therefore cannot be used in any rwd platform vehicles. The adapter plate that is currently on the market is for the 01e transmission to the rwd GM LS block. THe LS4 also has no starter provision. The LS4 starter is bolted onto the tranmission.

I wanted to use the LS4 do to the very compact accessory drive but seeing how that is not going to be possible, I will be buying an LS4 just for its accessories and then selling the leftovers. I'll throw the LS4 accessories on the LS2 I am picking up.

[dubiraq05]

is there anyway to use the ls1 in a b6 a4 5spd?

I think the reason people are not using them is this.. on forums they said that the N/A version of the engine weight is 257kg... when i do the conversion that is a ground breaking...567lbs

this might be one of the reasons they went back to the lighter almost as powerful 3.0L V6....

go check out some of the swap sites.. there are adapters all over.. that mount the ls1 starter up to it.. we just have to find someone who be willing to change the bell housing adapter up a little.. Im pretty sure if you call up that guy that sells the kits now and talked to him about it.. he prob be willing to do it up for us.. since its just a change in the location of the holes.. thats all..the engine is 6 inchs shorter.. so it would make the mounting of the radiator and such much nicer... plus the weight advantage of the tightly compacted accessory's make is so nice for our conversion..

[GURUMAN]

yess it will fit

[Storx]

more food for thought..was talking to guy on ls1tech he said that you could have a machine shop machine you out an spline adapter for the 26 spline end of the LS clutch.. so you can use LS series clutch if it would clear the inside of the tranny belhousing due to using a adpater plate.. giving you more room to run larger clutchs.. he said you can pick up an Katech twin disk z06 clutch for around 600 bucks.. and its rated for 809 tq...

[dubiraq05]

yess it will fit

so as far as the tranny adapter any b5 a4/s4 tranny will bolt to a ls1?

The engine s not 6 inches shorter. Only the accessories are shorter. But the accessories are interchangeable with all LS motors.

Those first two videos are of a 5.3 truck engine. It's an iron block and low compression just like the LQ4. It's called an LM7

[djwimbo]

L33 Vin code "B"

The L33 was an aluminum block version of the LM7, and was referred to as the Vortec 5300 HO in marketing materials. Power increased by 15 hp (11 kW), to 310 hp (230 kW), over the LM7, and torque was unchanged. It was only available on extended cab 4WD pickup trucks. Only 25% of trucks made in 2005 had the L33 engine.

That's the badboy I want (E36 swap). With a Fast intake, big TB and decent exhaust, it would make for a very fun car.

Or do the LQ9 block with the 4.8L crank, slight overbore, and total CI = 333. Which I could then make a badge from OEM BMW #'s to put on the trunk.
Higher revs (basically LS6 top end and cam) and great for light N20 use. Budget build and tire burner ... 2700lbs car with full interior.


http://ls1wiringharness.com/images/MVC-007S.JPG
Part# 4823-0120-N $445

Made for truck type air fuel management unit, 4.8 5.3 and 6.0 Drive by Cable engines, No transmission, NON emission, 2-O2 sensors

BTW, I can imagine shoe-horning it into a B5 will be comparable to the C5, but make sure you don't forget to do the connectors on the starter first, they're the biggest PITA of the whole deal.

how much was just the adapter plate? id love to buy a plate and when the moneys right go for the rest

good catch on the L33 i wander why he didnt mention it when he sent me the block codes that were aluminum.. ill message him on it.. to see if he knows anything about this engine..

were did you find that out??? this is the article i was linked to for the build...im not saying your lieing.. just wandering which answer is true...

'Vanilla poop with rust flakes'

See poop, see poop go, run poop run!

http://www.diyautotune.com/images/cars/parish/fairmont/DSC05038.sized.cropped.jpg

Sorry for that mental picture, but that's how Jim 'Parish' Neuenfeldt describes the color of this Turbo 5.3l Chevy powered Fairmont. And it only takes a glance to see why... but I think it's safe to say that no amount of the pink stuff is going to slow down how this car runs....

Built by Jim 'Parish', John Stevenson, and a handful of guys from Omaha, with the help of a whole bunch of guys donating parts and help, this rustbucket is more of a RustRocket... taking a class win in Hot Rod's Drag Week 2007 Daily Driver class with consistent 9.80's. Jim is no stranger to DragWeek-- take a look at his 10 second 5000lb 4x4 truck if you'd like, he took a class win at DragWeek the last two years in a row in that truck, this makes three....

You can read most of the details on the car in Hot Rod Magazine, there is a small spot on pg. 52 of the March '08 edition, and a six-page spread on the car in the April '08 HRM, but the high points are that it's running a Vortec 5300 Chevy LS4 motor from a GXP, a generic MP70 turbo, a bunch of ebay-special parts, and a ton of elbow-grease. We've been working with Jim for about 3 years now starting with that crazy truck I mentioned above which also runs one of our MegaSquirt EMS systems, and he came back to us for another system for the Fairmont. He's running a MegaSquirt-I PCBv3.0 Engine Management System and an Innovate Motorsports LC-1 wideband with gauge we donated to help the cause.

I'M going to work with Eric on a custom flywheel so a tilton style twin or tripple dics fits in this swap.

I will start with a stage 3+ from spec, burn it than swap the entire clutch flywheel combo.

I guess I'm really part of special R&D for Audi.

I really dont mind...

IF ever it comes out of control, like my other thread and everybody are ditching the 8k stage 4 buildups to get over 450 whp in Favor of swapping LS V8's

I will hook up with a vendor account, like Shawn/ARD/VAST did [;)]

[O2VW1.8T]

Found a buyer for my VR6 LOL, after i sell this and a few things i'll buy the adaptor plate, flywheel and starter from kitcars... The LS4 looks good found a few for about 1500 local and a couple under 800 bucks... guru thanks again for being the test dummy[:)]

[djwimbo]

good catch on the L33 i wander why he didnt mention it when he sent me the block codes that were aluminum.. ill message him on it.. to see if he knows anything about this engine..

The downside to the L33 is that you can't do much with the bore. Any pistons would have to be stock bore, or custom made (0.010" over with custom C/R) since it's a sleeved Alum block.
The nice thing is that it's pretty stout (power to weight) stock, intake and cam package brings it to life, the down side is that it can't do a ton beyond that without spending more money. Light N2O use is fine, but F/I is limited(~7psi).

Like stated before, if you want to go big, the iron block is the best and also the cheapest.

The L33 runs around $1000-1400 for a "drop out" engine = ecu, harness, all belt driven accs, manifolds and longblock.

F body camaro or corvette pan are the one to look for !

[skele4door]

The thread below will probably be useful to for deciding on pans when you figure out what kind of space you have. GM made quite a few changes to the designs to have better oil control, so if you can use one of the newer ones I'd suggest it.

If you end up needing to notch the pan you'll probably want to get a new pan from GM BTW. They are pretty porous and it's hard to get used ones clean enough to weld properly. Make sure you order the pickup for the pan you get and replace the O-ring as well.

http://www.ls1tech.com/forums/conversions-hybrids/817787-lsx-oil-pans.html

[AudiVWTech]

The Gto pan is going to work the best. The Gto pan is a front sump just like the 1.8t pan. The vette and the f body pan are going to have to be modified. The Gto pan looks like it's going to be a bolt in.

[revhards4]

hate to change the subject just a bit but has anyone looked into fitting a GMC Cyclone or Typhoon automatic transmission to the LSx. Would be great to have a beefy auto with a built/turbo lsx motor.

[AudiVWTech]

the typhoon transmission is just a rear wheel drive trans with a transfer case on the back of it that send power up through an external driveshaft to a front differential just like a conventional 4x4 truck. This kind of all wheel drive setup would be virtually impossible to adapt to our cars

Ya i really would prefer the LS4 aswell but i cant call the guy who sells the kits to see if he change the drill pattern to mount it to an LS4 engine because i prefer it for the sheer weight difference over the other engines.. plus people have turbo'd the aluminum ls4 with nothing but good results up around 800whp on the GXP's and fiero's that are running the LS4's
