S8 Motor (4.2L V8) Into B5?

[Siena]

As the title states. I finally made a decision, and sold my 2.7 V6 Biturbo.

Buyer came down last night with a box van, and took it away.

I've just purchased a complete S8 engine, from a 1999 Audi S8. Being delivered sometime next week, along with the airbox, MAF, instrument cluster, ECU / wiring harness. Only part missing is the viscous fan, but that's ok, as I'm running 2 electric units at the front (grille side) of the radiator. So, 340PS stock, loads of grunt, and of course, the V8 rumble.

Now, a lot of folk say it won't fit a B5, but I'll get it in. The more folk say it won't (guys that haven't tried) the more determined I am to prove it will. I never go by hearsay.

I have great confidence in my mechanical / electrical abilities, and not the sort to just give up. I'm initially going to fit the motor as it is, but will be going the forced induction route later. Either turbo/s or supercharger, will need to review space, first once installed.

Ordered a flywheel from Audi today - the V8-engined cars were never available in the UK with manual transmission. I'll of course, be installing it with my 01E 6 speed tranny, coded DSY.

Over the next few weeks, I'll be posting regular updates. Can't wait to get rid of the lame 2.6L V6 12V.

[317ssayzarc]

i wish you the best of luck, i REALLY do... but add me to the list that says it wont happen... hopefully that motivates you and you get it done because i want ME to be wrong [;)]

[pac1085]

i think he might actually be able to pull it off. i remember someone on here posted a pic of the v8 sitting in the b5 chassis and it looked to fit quite well. there will be a lot of custom work involved but I think it's doable

[1 sick s4]

ballin' good luck dude.

[Outkasted]

I remember one company putting it into an avant. and it was costly. I am trying to remember what company it was. It was an audi tuner i think in europe.

[UN-PIMP-Z-A4]

bah humbug
it will never happen!!!
Post pics whenyour done. Thanx [:p]

[SilverB5A4]

This would be my dream for the B5 chassis, and yes anything can be done with enough money and dedication, it just depends on how much of each you have :)

[aytheory]

twin turbo v8 FTW

[audiFUEGO]

cant wait to see... or should i say.... i cant wait to be jealous of you.

Make sure you take lots of pics and keep us updated along the way! [up]

I have a feeling that wacky orange widebody is going to become the sickest B5 anyone's ever seen. [:D]

[AudiA4turrrbo]

i've seen one put into an early 90's coupe quattro, it was tight, and it had twin k03's!

[UN-PIMP-Z-A4]

How much understeer do you anticipate?
LOL!!!

[Siena]

I only need me to motivate me. And the cost of the engine and parts is more than enough to gee me up.

I had the same reactions back in '96, I was one of the first to install an RS2 motor and 6 speed box into my '87 type 85 Coupe quattro. [wrench] Was very successful, and ran great times.

Then, www.dubmeister.co.uk and his type 85 90 quattro. That runs a 4.2L V8 from a 1993 Audi V8, installed by my fair hands. [cool] People doubted it would fit even back then, in 1999 / 2000.

I just laughed, and got on with it. Was a successful install, contact Paul Quince, the owner of Dubmeister. I can still see the expression on his face, as I began to tear his car apart, priceless. [cool]

[Siena]

How much understeer do you anticipate?
LOL!!!

Yes, the V8 sits closer to the front of the car by about half a cylinder.

It's also lighter than the cast iron V6, and only marginally heavier than the 1.8T I4.

[Siena]

I remember one company putting it into an avant. and it was costly. I am trying to remember what company it was. It was an audi tuner i think in europe.

Correct. It was Oettinger in Germany.

The recipient car was a 1998 Audi S4 Avant in black.

[317ssayzarc]

thats precisely why i really want to be wrong on this... im running out of revs/displacement on my setup and this is the direction i want to go in... [up]

[Flash]

The 12v is a cast iron block? I didn't know that. Is the 30v iron too? So if you get this going, which I'm sure a determined person can, and you boost it are you just going to run stock internals with low boost or would you rebuilt it and put it back in again?

Sounds like an incredible amount of work.

[fred2ka4]

This sounds like an amazing project and I can't wait to see the finished product. You don't need me to say that it can't be done to motivate you, as you already sound motivated enough to pull it off.

[>_<] [up]

Sounds like an incredible amount of work.

All the V6 blocks, 12 / 30V are cast iron. I believe the exceptions are the 3.0 / 3.2 V6.

Am lowering the CR, considering RS6 pistons, or other aftermarket items, dependent on what's available.

[onemoremile]

I've got a 9.2MB zip of a V8 block sitting in a B5 A4. PM me with your email address if you would like me to forward them to you. I'll upload a couple to post. These are from a guy that posted here about the swap.

Alright, got 10 images uploading right now.

[B5Jaeger]

It has been done before multiple times.

I'm sure you can pull it off.

You may have to punch the forward firewall back a bit on the lower (passenger side on UK cars) portion.

Otherwise you'd have to stretch the nose/frame out.

Thread bookmarked, will follow with interest. The motor is all-aluminum and should not weigh substantially more than any of the sixes. PES is coming out with a blower for it, which should get you to around 450hp with instant response and plenty of low end.

its been done

All the more reason to do it again and a little better. [;)][up]

[legionvr6]

good luck i REALY wana see this. please take an insaine amount of pix.

oh and to get you going some more. it wont fit you'll fail. lol good luck dude

[DGAFxxx]

I'll give $100 to the first person to swap a F20C1 honda engine into a b5, and I'll give them an extra $100 if they add forced induction to that.

[onemoremile]

Why not a 20b three rotor or LS7 with titanium rods and dry sump?

[Siena]

Thanks for the pictures!

That's a later V8, with chain driven camshafts at the rear.

Looks nice and snug in there.

[ibe3pac]

i fucking love [az] and how this forum never makes me happier!! lol... good luck bro.. i hope to see tons of progress by june when i get out of boot!! ill be looking forward to seeing this post when i get back... and ill have one of my buddys keep me updated... GOOD lUCK... and idea... maybe see if you can shorten the rear drive shaft an inch??? so the motor can sit back farther... im assuming your making your own motor mounts too so just an idea... keep on [wrench]... and good luck... bc this will be an awesome fucking car and do you already have a shell?? or what year b5? maybe 1996 or 1995 bc of price?... just a couple ideas and food for thought!! [:D]

[onemoremile]

Thanks for the pictures!

Yeah it looks like the B6 S4 V8 which is a little shorter than the one from the S8.

[blacka4]

what about the belt accessories???

[onemoremile]

Go oldschool and run the alternator off the driveshaft and everything else off an electric motor. [:p]

[B5Jaeger]

Plenty of room for a blower in thar.

Here is a same type of thread by a guy with a B6 1.8T doing the V8 swap.

[Militant-Grunt]

Well you're going to have fun cutting up the firewall, because thats the only way that V8 is fitting in there properly without compromising the nose of the car. Same was discussed when someone proposed fitting a AAN 5cyl 2.2.

[GiacGRs4]

it can be done just going to be nose heavy

yeah our cars are nose heave with the 1.8t . yeah the v8 its lighter then most 6cyl but is not like its almsot the same as the 1.8t.nice face by the way

[onemoremile]

An all aluminum V8 is pretty close to an iron block 4 cylinder when you add in the turbo, intercooler, and all the associated piping. It might even be lighter when finished.

THAT was what i meant... sorry it was implied and not written, my mistake [:o]

[Siena]

Morning guys.

As I'm starting from scratch, and fitting the 01E 6 speed, I have the advantage of being able to have the motor / tranny as far back as is practically possible, with half shaft angles in mind. And of course, the front clip (fibreglass) can be trimmed back.

I'm going to purchase a dog-rough, cheap, scruffy A4 front track, and carry out all the research and development on her - fitting the engine, wiring it up etc. Once I'm satisfied with the fit, then it'll be a weekend of transferring the lot over to my Orange Widebody.

The engine mounts may not be as much as a problem - the B5 and C5 (A6) share pretty much a similar front set-up, and the engine mounts are aluminium, and bolt to the main frame, between the body and the subframe.

So, it MAY be possible to utilise the mounts of a V8-engined A6. If NOT possible, then I'll have some custom made.

As the wiring harness of the S8 bears no relationship to our B5 chassis, I'm ordering an aftermarket ECU. I'm running QPENG / MBE 997, with custom harness (made up from the original). I've used the smaller MBE 992 for all my clients 1.8T conversion into Golf I /II / III. Advantages over the stock system is it's flexibility.

It comes with all the software / leads, and is fully mappable via laptop and serial port. Used on a stock S8 motor, 380PS is very achievable, combined with some light headwork. I'm not going to go mad on porting and polishing on the heads - it's less effective on a turbocharged motor than on a n/a one.

Though the motor's being supplied with the ECU / instrument cluster, I won't really need them. My V6 tachometer will still be accurate with a V8 motor, as the MBE 997 is fully configurable, and can be configured to 2-4-6-8-10-12-14-16 cylinders, with the correct pulses for whatever tacho the car has. I also won't have immobilliser issues to overcome, though the early S8 didn't have the immobilliser combi-processor built into the instrument cluster. It was a seperate "black box" similar to B5 of the same era, under the steering column.

[zionrider]

sounds like you have some fun times ahead of you. It will be great to see the progress of the car.

[Shomegrown]

You guys are definitely misinformed about the weights here.

The 1.8T is substantially lighter than the V8. The V8 weighs about the same as the 2.7T (195 kg vs 200 kg), but is longer so the weight is centered further out in front of the axle.

That's fine.

I haven't weighed either, but having moved both by hand, I was able to just about lift one end of the V8. The V6 Birurbo, I could hardly even drag.

But it's all good, she'll fit fine, and suspension set-ups will be the last thing to play about with. Right now, the least of my immediate concerns.

I'm busy trawling through wiring diagrams, of my B5, the S8 and the MBE 997, so plenty to keep me occupied.

[Maverick]

I see the connection now. You and Martin from the B6 forum. cool to see what you are doing

[Siena]

I looked at Martin's conversion. Pretty neat. But then, the B6 WAS available with a V8 engine.

We were just guessing and not quoting anything. Thank you for real numbers. [up]

Is that 2.7T weight with or without the turbochargers, intercoolers, and piping? Do you happen to know what a 1.8t weighs?

[Stampy]

just wondering....Did you consider doing a W8 or W12? I was always surprised that no one does the W8 conversion seeing as it was stock in the b5.5 passat. Figured it would be easier. Also thought the W12 was supposed to be about as big as a regular V8.

Kick ass that you are doing this man. I really look forward to reading the updates. I wish I had the facilities to try this myself.

[onemoremile]

The W8 doesn't make much power for it's additional complication. A local had a Passat W8 4Motion 6 speed and it was definitely less performance oriented than a B6 S4.

[audiFUEGO]

Jim was that W8 chipped? Because I've driven stock B6/B7 S4's and was not that impressed at all. I'm sure a basic chip could open that W12 up nicely

[onemoremile]

He was selling it and I never rode in it. He sold it because it wasn't faster than his old mk3 VR6. The W8 disappeared for a reason. It seems it was really just an elaborate technical exercise.

[317ssayzarc]

dont think so... naturally aspirated motors dont "open up" with a chip...

[offroader1006]

they open up with 12k rpm capable heads and bottom end[:D]

thats the route i would go if i put a V8 in the B5.

DTM style revving the phuckouttofit. i dream of a V8 with a 10k+ redline in my car.

Go read some posts in the B6/B7 S4 Forum. People are very happy with their chipped V8's. They claim night and day difference with better throttle response and higher rev limiter.

its all a matter of opinion as to whats night and day... BUT, doing some digging i found an awesome comparo, same day, same dyno and multiple chips! bottom of the page http://www.audiworld.com/news/05/b6dynoawe/content2.shtml

doesnt look like ish to me lol, forced induction ftw! [up]

[audiFUEGO]

well i agree the "power gains" aren't as substantial as a turbo car. But 15hp and 15tq increase is something. And besides its all about how much more power it puts out. Like i said, people are loving their more responsive throttle, higher rev limiter, and 4-5 mpg increase. [up]

[GramCracker]

Siena, DO THIS. I really can't wait to see it finished. I really have faith in you. Your going to have the most bad ass car on here imo. Keep up the work man, I love your car!

[Borden]

sweet so now when my engine blows up sometime in the future or i feel the need for a V8 i can look back at this thread and have inspiration...really cant wait to see this finished Siena![up]

[Siena]

Thanks guys!

Engine's being delivered next Saturday. It'd have been delevered Tuesday, or any other day within the week, but I don't get home from work till about 17:30.

Can't wait to get started. As I previously said, I'll be installing the motor stock, as in no turbo/s, that can come later.

[4ringAR]

You crazy!

Cant wait to see the progress pictures and outcome!

[Siena]

Lol.

Been going over the schematics, of my own B5, as well as the S8.

I MAY be able to use the Audi Motronic set-up after all. I'm pretty confident I'll be able to sort the wiring out, and achieve a factory look.

Using aftermarket is cool, but it means I'll lose the on-board computer, as it won't be compatible with anything other than the OEM management.

If that's the case, I'll use the S8 instrument cluster. Not for anything such as immobilliser issues, (only '99> had the immo. combi-processor in the cluster) but to retain an accurate tacho, and the on-board computer will be accurate too.

As soon as the engine arrives, I'll start on the wiring harness, see if I can make it plug-and-play.

[317ssayzarc]

that sounds like you can work that out as long as you can fit that cluster [up]

[onemoremile]

The S8 cluster is the way to go as long as you can make it work. As far as I know, the B5 clusters only work with 4 and 6 cylinders. They can be recoded for region, fuel type, induction type, and cylinder count. I had to do this when I swapped a V6 cluster into my 1.8t and it only read 2/3 of the RPM. My idle was 600 and redline was 4000 before the recoding.

[Siena]

I have managed to work out the engine wiring schematics of the '98 S8, as well as my car, so should work fine.

Only issue I can see as regards to the cluster, is the S8 doesn't have extra instrumentation (volts and oil temp.) I'll probably either get genuine VDO items, and build a dash / A-pillar pod for them, or it MAY be possible to mount the S8 tacho into the B5 cluster.

I guess till I've got both units side by side, it'll be difficult to tell if they'll be compatible.

Which hybrids did it have? rs6 k04?

well i guess if siena turbos the v8 it'll will nevertheless be the better choice [up]

It WAS a 2.7 to start.

Turbo's were GT series, will dig up the details later.

very cool cant wait to see it new idea for mine when it blows up

Just got email from the engine supplier. It's being delivered tomorrow midday.

A pain though, as I've got today off, and could have had it delivered this afternoon! Still, not too far away.

5 cylinder motor is a LOT longer than a V8.

[onemoremile]

Didn't I post a bunch of pictures showing that the engine fits? The easiest way would be to cut the radiator support between the headlights and make a custom one from tube stock that moves the radiator forward as much as possible. Use slim electric fans to make even more room. You could even use a pusher fan on the front of the radiator but that depends on how the air condition condenser is set up. Audi already stuffed 10 pounds of poo in a 5 pound bag, another pound shouldn't be that bad.



I found this old post about recoding clusters. Looks like you can code your old cluster for 8 cylinders.

[Siena]

Well, the engine, instrument cluster, ECU, ignition key, wiring harness, airbox / MAF have just turned up.

It's huge. So, the hunt's on for a dirt cheap Audi A4 front track to use as my test bed. Both myself and the driver were able to lift it from the back of a station wagon without busting our backs.

My old Biturbo V6, was definitely heavier, regardless of Audi's figures.

[TMorris]

True. The S8 cluster is the same shape as the B5 one, but, we'll see when it arrives.

I have been looking at clusters and the A6 cluster looks to be the same as the A4/ S4, could that cluster work as well since the A6 came with an optional V8?

Have you found a donor/ practice car yet or are you going to be like Mike and and "Just Do It" ........... [:D]

[Siena]

No donor car yet. Can't afford to tear my car down, it's my daily driver.

I still need to purchase a manual flywheel for an early S8, or even for an Audi V8. Never sold as manual in the UK, so either buy new from Audi, or ebay.de as German-spec cars had manual as an option.

[fred2ka4]

I'm not a 100% sure, but I don't think the V8 was ever offered as a manual in the US but I could be wrong.

[Siena]

I don't think it was either. German cars got both, right from 1989, starting with the 3.6 / 4.2 Audi V8, to all the V8-engined A8 / S8.

Damn bro good luck. Don't worry haters said a V-6 S-4 engine couldn't fo into an Elise and it was done. Definitely will follow this thread.

[gruppe5]

I have the same swap about to take place within the next few weeks. Good luck with the flywheel, I didn't find too many available when I was searching, but I did eventually get a great deal on a use one with at pressure plate. 034 sells the stock steel one and the aluminum version, the steel flywheel has the 60-2 machined right onto it as well. It is pricey though, $775 U.S. before shipping, I believe they get them direct from Audi. I am 100% confident it will fit, the ABZ measures about 19 3/8 inches, I have measured multiple times and it shouldn't be an issue. I know the radiator and hose will be tight but everything else should be straight forward.

[Nebone]

There is a guy from New Hampshire or Vermont who has a Coupe Quattro with a 3.6 V8 (its twin turboed too) and with a manual transmission. I'm pretty sure US never offered a manual 4.2 but maybe a 3.6. He would have more information on the V8 swap. He could be found on Audi World.

[Siena]

I guess that's Marc Swanson, or something like that?

Red Coupe quattro.

[Bic-Ball]

the swap wont be cool unless you get that key into a switchblade.

[Siena]

the swap wont be cool unless you get that key into a switchblade.

My car's already been converted to switchblade key, due to me using late front doors, for a 2000 model, with the later door handles.

I used the later door lock, ignition lock, glove compartment lock, so one key does all. My original old key was the same as this S8 one, I cracked it open, and transferred the little chip over to the switchblade, and it works fine.

I'll be doing the same with the S8 key, and the key itself, will be consigned to the trash can.

Yup, that would be Marc. He is a friend of mine, lives about 25 minutes away. His swap is irrelevant in this situation, mainly because he put his V8 into a Coupe which does not really have any similarities with an A4, and he also installed a 3.6. He is in the process of installing a 4.2 but not an ABZ, he is using the earlier version. If you had gotten an later 4.2 your clutch and flywheel issue would be solved already since they had an 8 bolt crank and the B5 S4 items would bolt up, but I believe that you have the 10 bolt crank like I do. Hopefully you can find one used. Did your motor still have the flex plate attached? If so save it because you will probably need it.

[Siena]

@ Gruppe: Wrong with regards to the flywheel. My first V8 conversion was in a type 85 90 quattro, belongs to the owner of www.dubmeister.co.uk (Paul Quince).

It was an early V8, a 4.2 (ABH). ALL 32 valve V8 engines run a 10-bolt flywheel, we ended up getting one from ebay.de Audi went BACK to an 8-bolt flywheel on their V8 engines with the introduction of the 40V motors. The only 40V motor that retained the 10-bolt flywheel was the RS6.

Yes, the flexi plate is still attached, as is the torque converter. The 10-bolt flywheel, for the manual V8 3.6 / 4.2 is available through Audi, as well as the unit for manual S8 (early 10-bolt).

Problem is, it's exchange. Without an exchange unit, it's just over £300. I haven't had time to search ebay.de yet, but if all fails, I'll buy new.

[gruppe5]

Correct, I did intend to say later instead of earlier, my hands didn't obey my mind. Post edited.

[Siena]

Lol, that's ok.

[Siena]

Mine's an AHC motor. How far have you gotten in your quest for V8 power in your B5?

[Siena]

By the way, the S8 cluster doesn't fit within the confines of the B5 facia - too wide.

I'll just either locate an A6 with a V8 motor, and use that cluster, (not easy, as it MAY be a later car with different plugs) or get mine coded to give correct tacho readings.

I secured an ABZ engine, along with European S6+ flywheel and pressure plate, VEMS engine management, and most of the ancillary items. As far as actual work, just alot of measuring, waiting for the weather to come around so I can put my S6 back on the road and start the swap. I have just about completed my wire harness, I need to retain the ability to plug in the factory ECU for emissions testing, so the VEMS will be plug and play. If all goes right I will have started within the next two weeks, and will have the engine completely mounted shortly after. I still will need to figure out what to do about the TECU so the car will actually run and drive. Maybe I will post some pictures here, gotta find a host I believe.

[Siena]

That's good.

I've got the lot, bar the flywheel. I haven't seriously began my search yet, got a lot on at present.

I've also got the downpipes / catalysts. I'll be using just the downpipe flanges, then my guy will make the rest of the system, running sport cats.

I'm still going to try retaining the OEM Motronic system, so my DIS / on-board computer is fully functional.

[onemoremile]

I'll be talking to you about that at some point.

To give you an idea how it works I added a couple up for you. The only real difference is the first couple digits which are for pre or post facelift and options. These are A4 codes for the A4 cluster. The S8 cluster would probably need S8 coding which should also be on the site linked in the post with the coding info.[up]

[bloodstar57]

Siena Good luck i really hope it works i would love to try this. Are you planning on keep the motor stock?

[Siena]

Keeping the motor stock for now, will go the turbocharged route later.

A 190 horsepower gain over my stock 2.6 V6 is worthwhile, for now.

[Siena]

As stated above. I'm not bothered if it's scruffy, it must meet the following criteria:

1) It MUST have a minimum of a 3 weeks MOT.
2) It MUST be able to at least drive from location to mine. Engine can expire after I get it home, it wouldn't matter. Even if the motor's banging it's guts out, and the transmission sounds like it's full of gravel, no worries. It just has to get me home.
3) Road Tax isn't important, though a month or less remaining will be great.
4) It MUST be rot-free.
5) It MUST be an early car - M to P registered.
6) It MUST be a manual
7) Above all, it MUST be dirt cheap. I paid £500 for my '96 2.6 Quattro Sport, with 2 previous owners.

It's going to be used as a test bed (R&D) for installing an S8 4.2L V8, so I'm not too bothered about the general condition. I've chosen a 1.8 20V non-turbo, as they are the cheapest B5's available, even cheaper than the 1.6 that was launched later.

Anyone has such a car, or knows of one going for sale, spares or repair, please let me know. I'm not looking to pay more than £250 for a scruffy car, I'll buy it, as long as it meets the above criteria.

I've found a local CNC firm that do flywheels.

They stock SM flywheels for S4 / RS4, 1.8T and make just about anything. Brake caliper mounting brackets, custom engine mounts etc.

They're making me a one-off flywheel for the S8.

I'm not really going to bother buying a R&D car. I'm just going to buy a cheap runabout, and get straight into the project.

No power?

My current 2,6L V6 12V = 150PS

S8 motor, 4,2L V8 32V = 340PS

So, pre-turbocharging, over double the power of my current motor, almost 200PS more.

So?

[audiness]

how many HP is 1 PS?

what does PS stand for?

[B5Jaeger]

Power-Stoff!

And, Siena's car will be pretty serious when he gets it together. The 4.2 is the lightest and makes the most power easiest, across probably the best powerband of all the motors listed. I am sure his car will rip on Stage 3 A4s and Stage 2 S4s...easily.

Then, if PES ever comes out with their 450chp supercharger, bolt on mayhem.

Well guys, just bagged myself a '96 (P) Audi A4 1.9TDI, for the princely sum of £100.

The owner ran her low on oil, now the big-end bearings are worn. May just need shells.

I made him an offer of £100 about 2 weeks ago, but he was adamant he'd only accept £200. So, I walked away. Back from work today, and he called, accepting my original offer.


She's an SE model, which means it has climate control, in dark metallic green, and has A4 competition alloys, same as my originals. (7"x16" with 205/55x16 rubber). I'll be picking her up on Tuesday, just round the corner from me.

I intend to buy new shells, and rebuild the engine.

Whilst it's out of the car, I'm going to bolt my S8 motor into the bay, and get the fit sorted. May require custom engine mounts, but we'll see. There's a possibility the mounts for the 4.2L V8-engined A6 C5 MAY fit, as the A6 subframe is no different to that of the A4.

Pictures will follow. I should imagine my flywheel is ready (thanks Tuffty), though it wouldn't matter if it isn't, as I don't really require the flywheel to bolt it to the 01A / 012 5-speed, as it's just a trial fit, I'm not going to be attempting to get the motor running in a diesel-engined car, as the fuel tank is wrong.

Still, who knows? A gallon of petrol, a length of petrol piping for feed / return, and an inline fuel pump from an Audi Coupe type 85, or a Golf II GTI could well serve as a fuel tank...

The A4 1.9TDI will of course, be rebuilt back into a 1.9TDI, once all the R&D is completed. Pictures will follow.

[snoop]

So the plan is to do all the work to get the V8 into the TDI car. Once that is sorted out put the V8 into the RS4 with ease, then put the tdi back to original and sell it?

The original plan was yo use the TDI purely for R&D, then sell her on as a stock car, yes.

But have had a change of plan. The TDI will indeed be returned to a stock car, but she'll also be going into the bodyshop, for some "changes", including a color change. The body changes won't be as extreme as my RS4, but still pretty sharp.

In short, she's become a project in her own right.

As for the trunk on my RS4, it's a facelift one, and European cars had a couple of touch pads incorporating micro switches, as well as the 3rd button on the fob.

[Bic-Ball]

So you're going to keep it after all? Jealous.

Nifty with the trunk, I've always wanted a trunk open button like my dad's Passat, it's much easier than using the key, I can never get it to open on the first try. I do have to say though that I like the trunk with the handle/bulge above the plate better, I think it added a little something to a pretty flat area.

[Siena]

Well, my flywheel's ready for collection at last.

My S8 wiring harness is being modified.
This also removes the S8 auto box wiring and massive ECU multiplug. Will retain the OEM knock sensors, but will be losing the MAF, and gaining a 3-bar MAP sensor.

Also, ditching the OEM S8 twin-Lambda set-up, in favour of a single wide band Lambda. Great for mapping and set-up, essential for my twin turbo configuration, which will occur later in the year / early next year.

ECU is aftermarket. I hope to get the engine running on the bench before August. Should be fun - just the OEM V8 headers, no silencing, my neighbours are gonna love me.

[Siena]

My flywheel turned up Monday evening - it was wrong!

Either it was made wrong, or the wrong one was boxed up for me. It had the correct dimensions, but had 8-bolt fitting, which is ok for Audi I5 and V6 engines. My S8 motor has 10-bolt fitting.

So, it's a set-back. I now have to wait for a new one to be made. How they got it wrong beats me, as I left the OEM S8 flexi plate as a template.

I'm off to Brazil in August for 2 weeks, so this is an arse ache.

[TMorris]

im just glad there is still progress.

[Siena]

I spoke to TTV Racing today - they're completing a new one today.

The owner of TTV-R's son lives about 2 minutes from me, and he'll be dropping it round to me tonight.

They asked if 23:30 was too late to knock on my door, I said it was fine.
So, just waiting.

Flywheel will be bolted to the S8 crank over the weekend, after purchasing spigot bearing.

Need to bolt the 6-speed tranny to the motor, as I need to mark the recess where the crank trigger will be at TDC, and the appropriate map can then be loaded onto the ECU.

Removing the wiring harness too, to get it modified for the aftermarket ECU, and remove the auto tranny ECU connector / coaxials.

We're slowly getting there.

[Siena]

More work today.

Removed the wiring harness, ready for modification. Includes removal of the auto box ECU / connector, replacement of the main ECU connector with the VEMS one...

http://i67.photobucket.com/albums/h299/Lovindeer/14062008649.jpg

Engine's on TDC, in theory the 2 missing teeth should be close by. But, it would appear the 60-2 teeth location is different between auto and manual cars.

Each tooth is 6 degrees. The sensor location on the transmission is 11 teeth before the timing reference. The orange paint denotes the sensor location with the transmission removed.

So, the EMS will be mapped to recognise the settings...

Nice write up so far.

Is that trans THAT long b/c it's the 6 speed? The 01A's don't have that Iron center section or that brace on the right side by the shifter linkage.

You're building this car in that garage? That thing is tiny, I like my 2-car here in the states. I will say this though, you know what you're doing, and the size of your garage doesn't make/break the builder.

The 6-speed is only marginally longer than the 5-speed 01A / 012.

I'm building the car outside. Lovely weather, a few cool beers, and life is all good. [cool]

I'd have to see them side by side, but it looks a decent amount longer b/c of the iron section in the middle.

SIENA will be successful, if there is a will there is a way. All it takes is time and money.

[Boris]

Siena I may have missed it, but for what reason on earth did you choose the S8 engine? Its what 360 hp ? I read in the other thread you want to give the s8 some forced induction--but a nice 2.7 tt with a Rs6 or larger turbo setup will make more power anyday than the s8 crammed into the b5, even w/ forced induction...is it just that you love the easy torque?

I am very impressed that you are doing this. I just wish you were putting in a Ls7 or the engine from the 300ZX, I never thought much of the s8 engine

Siena with your knowledge I bet you could make a single turbo kit for the 2.7tt for the b5 s4 guys etc. Have you ever been interested in doing so?

Either way good luck , and I think what youre doing is awesome!

[Siena]

Boris, I appreciate your comments.

I did originally consider the 2,7 Biturbo V6 - I sold mine to make way for the S8 motor.

Yes, the Biturbo V6 would have been an easy option, done in a weekend, and driving. But, I want something unique, an engine not available from the factory in a B5, hence the S8.

I also love the low down torque, and of course, there's the soundtrack! With forced induction, the larger capacity S8 motor will easily make more power and torque than the V6 Biturbo, with a lot less boost too.

I have considered a single turbo kit for the V6 Biturbo. A single, large unit, that'll not only make more power than the OEM set-up, but will not require an engine pull if replacement is required. It's still early days though, but still something I'm considering.

Either it was made wrong, or the wrong one was boxed up for me. It had the correct dimensions, but had 8-bolt fitting, which is ok for Audi I5 and V6 engines. My S8 motor has 10-bolt fitting.

So, it's a set-back. I now have to wait for a new one to be made. How they got it wrong beats me, as I left the OEM S8 flexi plate as a template.

I'm off to Brazil in August for 2 weeks, so this is an arse ache.


Later 40V V8's had 8 bolt crankshafts. Perhaps they got the year of the engine confused?

[Siena]

Yes, all 40V V8 motors, bar the RS6. had 8-bolt fittings.

Was funny how they got confuzzled, when I left them my OEM S8 auto driveplate, with 10-bolt fitting!

[Jurjen]

Im curious, hows this build going?

[Siena]

Im curious, hows this build going?

Still gathering parts.

All that's left is to find a pair of 1.8T/V6 FWD front axle shafts, as the inner CV joints are 108mm, to mate up to the corresponding flanges on the S4 6-speed box.

All non S4/RS4 quattro front axles run 100mm flanges.

Then, an RS4 B5 clutch. After that, I'm good to go.

[offroader1006]

do the axles need to be from a manual box?

i have a set for dirt cheap frmo a FWD auto 1.8t

Yes, the axles need to come off a manual.

The auto box is a fair bit wider, so the shafts will be correspondingly shorter. Thanks for checking though! [up]

[Splinter]

bump for a wicked project... updates?

np, anything to help it get done

[Siena]

Well, one less thing to worry about...

My clutch turned up last Thursday...

[Siena]

All I'm waiting on now is a pair of 01E DSY-compatible axle shafts, which I've located, and should be with me sometime next week.

[t1demont1]

that pressure plate looks intense

[Siena]

that pressure plate looks intense

Yeah, it sure does.

It's one I've used before in my old RS2-spec B2 Coupe Quattro.

Last power run was 426ps / 411.3lbs-ft. I was able to do full bore standing starts, in the dry with grippy tyres, and it never once slipped, despite 7,000 rpm launches.

[t3han0maly]

subscribed.

awesome project. cant wait to see the turnout.

[kovalevandrew]

Any progress...?

[b5s4tt]

most original thread ive seen in a while. very informative

[Siena]

Not much happening right now, I'm afraid.

Too cold to do an engine pull on a daily driver, worse when the replacement engine's a hybrid!

Will begin the install in March, right now, preparing for a move, getting married next year, and getting ready to launch our business.

Thanks for being patient with us!

[xraycer2012]

Congrats and good luck! Now I have two reasons to look forward to march, the first b5 v8 rs4 sedan, and the start of my gt30r DD build [:D]

[Siena]

Looking for a cheap daily beater, as I'll need one pretty soon.
Definitely need to be able to get around whilst Outlaw's off the road, can't afford to be immobile.

I'm looking at a week to do the complete conversion.
I have everything ready, apart from:

Exhaust system - I'll have to graft on the existing OEM V6 one, just to get me to my exhaust shop, where a custom stainless system's going to be built, twin sport catalysts, ending in dual-exit ovals, B7 RS4-style. Bore size will be 2,5".

New power steering lines, that will be made up, once the car's all running - I'll be driving her down to my local hydraulic hose specialist, they'll make me what I need in stainless steel braid.

New fuel lines, again in stainless steel braid.

RS4 clutch is fitted, will post up some pictures in the week.

Roll on spring!

[A4Rob]

Awesome. Get er done

[Kyle H]

Awesome! I can't wait to see this thing completed.

[acollicott]

Looks amazing I can't wait to see it all put together

[josmo]

how much is the weight diff going to be?
i've seen some new model miata's with a ls1 which is an aluminum block so they only gain a hundred or so pounds. Thus with the extra power they can cruise at 1-2k rpms instead of 3.5-4.5k (with the stock 1.8) on the freeway and get 30mpg instead of the stock 26-28

think you'll get better gas milage with the v8?

[travelbytommy]

Well I can't say from experience with a V8 A4, but when comparing the 2.8 in my A4 to my 5.7 V8 in my Corvette Z06, I get almost 50% better fuel economy. While some of that is obviously the car being lighter and more aerodynamic, I think if you were to have a lighter engine with more horsepower doing the same amount of work it would get better mileage.

Of course the biggest issue is gearing. If you increase your horsepower of the same engine you started with, say with a turbo or supercharger arrangement, but keep the same gearbox with same ratios, you will lose mileage because your gearing is not optimized for the extra horsepower. If you gain enough horsepower to facilitate shifting earlier it would make a difference, but in the case of the A4 (at least mine anyways) I am already in 5th gear around 45 during normal driving. Since there isn't a higher gear, my mileage would not be able to increase unless I were to swap for a 6 speed or change the gearing to make use of the higher horsepower.

[Maverick]

those bolt down CPs are better

[GQ//S4]

Subscribed! These types of projects make me so happy to be a car lover

[josmo]

PLEASE post pics of the instal.... dont cut us short like that guy from denmark PLEASE

[solowb5]

I think he is held up with other things right now.

[Siena]

Sorry guys, will try not to hold you up.

Stand alone ECU, wide-band Lambda and wiring harness all ready, after being modified.
Have also lost the massive ugly auto trans / tip connectors, including the parts that go to the actual tranny itself. So, the harness looks much neater.

So, am good to go now, just need the days to start getting longer!
Will keep you guys posted with sequence pictures.

For now, will post up pictures of modified harness, ECU and wideband.

Innit, huh?

[ghost6303]

you need to stop what your doing and finish this car so you can put up some decent pics for me to look through.

[docurley]

Well he picked up my RS4 uprights with drive shafts Saturday which were from my old A4 so I think the final things are ready to start and I know he can't wait to get started.

[Siena]

Probably, but I also have a full-time job.

And a life beyond Audi's, with other priorities. [rolleyes]

[B5 Quattro]

LOL.
You just keep at it when you can man !
We will be here.....
Do you man !
lol.

sorry if that sounded a little sharp, meant it more joking-ish, but im as excited as everyone else here to see it up and running. thats going to be an incredible car. [up]

Sorry I took things the wrong way buddy.

Our crap weather's not helping matters either - want it to be dry before i get stuck in, with more daylight hours. [:)]

[boostedup]

Your my HERO.... :)

[Siena]

The green coaxial is for EGT sensors, which I'll be purchasing seperately.

[Siena]

Little update:

Due to the fact a client of mine in Singapore is after all parts to convert his B5 1,8T to manual (Singapore B5 1,8T's are all auto, unless you go quattro) I bought a donor car.

[Siena]

Drives well enough, for the princely sum of £275.

I'll be stripping the motor and manual tranny out over the weekend, and as a test bed for my S8 motor and 6-speed tranny, she's ideal.

Besides trial fitting, it gives me the opportunity to get custom engine mounts made, which will be solid aluminium billet. With an I4 motor, the vibration levels will be high, but a V8 motor's much more balanced, and forgiving.

I'll also be getting the engine running in the test car too, and map out any bugs while I'm at it. Updates via the usual pictures will follow sometime next week.

[leon]

You're going to use the1.8 tranny for a 1.8T?
This tranny is shorter than the 1.8T one, so only thing he does when he rides the car is shifting.. And the diff is different, you will als have to swap the diff.

And im looking for an 2.8Q tranny, do you know something in the UK, a complete car is ok.?

[Siena]

^^^ I have a 2,8 tranny available.

The 5-speed in that 1,8 is coded "CJQ,", which is a 1,8T version.

Not sure if this car came this way, or it's had the tranny replaced with a 1,8T one, but at least, it's the right one.

[Flash]

This keeps getting better and better. Maybe I missed it, but are you doing all the work outside? If so, wow.

[Siena]

This keeps getting better and better. Maybe I missed it, but are you doing all the work outside? If so, wow.

Yap. Doing all the work in the open, in my driveway.

Weather's getting warmer, at least I can get brown whilst I work. [>_<]

[leon]

What code is the 2.8Q tranny, Siena?

[Siena]

Leon, I'll check the code tomorrow, and let you know.

[Bic-Ball]

i thought you bought a diesel a4 for this purpose?

[Siena]

i thought you bought a diesel a4 for this purpose?

I bought the A4 1,9 TDI for £100, and someone offered me £700 for it, so it had to go.

Besides, I wouldn't have got the engine running in there, as it would have meant sourcing a petrol fuel tank, lines, electric pump and wiring etc.

With this R&D car, it's dual-purpose - has all the parts for a customer's manual conversion, and is an ideal test-bed.

[Papa Stone]

Siena I see you already bought your ECU!! Did you look into what I recommend you to power your car??

[Siena]

^^^ Do you mean the 034 set-up?

[Papa Stone]

yes

[Siena]

^^^ No. I've purchased my VEMS set-up since last August, and the wiring harness has been configured to match.

The same set-up has also been used for Audi V8 motors in the UK and US with great results.

[Papa Stone]

can't wait to see your project rolling .. I will be starting mine soon and will post pics..
I am already ahead with the painting and I am going a easier route than yours (engine wise). But in my case is not my daily so I will start with interior while I go for engine

[Siena]

Nice one, Papa.

Looking forward to your updates, sounds like your car's going to be a beast. [up]

[andyrew]

Drove my v8 powered 914 today, I think your going to like your car... :)


I must say that no traction till 40 is a little fun :)

[Siena]

^^^ Sounds good, Andrew.

What V8 is fitted to your Porsche, and what management are you running?

[Siena]

Just spent the day stripping down my R&D B5.

And proving that V8 + 6-speed into B5 does go.

Pictures being uploaded, waiting for phone to charge...

[Siena]

Bolted in 6-speed tranny with the S8 motor.

Firewall didn't need bashing or cutting, hood shuts with room to spare. I'll be fabricating engine mounts, at least the driver's side one.

I was more interested in seeing if the front clip would fit, and yes, it does.

[Nebone]

More room to work with than if there was a 2.7T in there. Are the mount locations lined up fairly well? Are you keeping the 2nd firewall?

[docurley]

nice work oh and wow.

[Siena]

More room to work with than if there was a 2.7T in there. Are the mount locations lined up fairly well? Are you keeping the 2nd firewall?

Yes, more room than you'd get with an S4 motor.
The 5V heads are slightly fatter than the 4V ones, so although the "V" are 90 degrees in both V6 and V8, the 32V motor has more side room. Looking at the manifolds, it's possible to have custom ones for turbo applications, that'll fit even closer to the block.

Mounts are close, but I'm fabricating new ones. Keeping the second firewall.

[gruppe5]

What mounts did you end up going with for the engine? Do you have any pictures of them?

[Siena]

Haven't made the mounts yet, will get them sorted in the week.

[black99.5a4]

it looks sooo good man.. almost makes me wanna pick back up the 4.2 plan you helped me lay out.
