BT planning...

[ghost6303]

ok ive been planning this build for several months. lots of great info on this forum and others, and i think i have my shopping like somewhat complete. just wanted opinions from the guys that have done this before. and to organize myself into one thread i can come back and read later.

plans are: 3076r turbo on a 2 liter motor 92.8mm x 83mm

heres what i have so far.
98 A4 1.8t quattro

i bought a spare AEB head, recently refurbished (few bent valves), though im thinking i want to upgrade the exhaust valves (to inconnel) and get a 3 angle grind going while its all apart. plus titanium retainers and high rate springs. i kind of want to do cams in the future but thats not in the plans right now.

i got a spare 058 block that im going to be building on, going with 83mm bore, as soon as i get pistons and rods, and find an ABA crank il send it off to be hot tanked and honed. my friends dad has a lathe to trim up the IM shaft gear, i read about 6mm thick is the way to go with the gear, depending on the rods, can anyone confirm this number?

other stuff i have...
-milltek non resonated cat back
-LC1 wideband O2 sensor
-turbo xs HPBC MBC
-garrett FMIC
-Forge DV
-front and rear sway bars, end links, and metal rear sway bar uplinks
-DXD stg 4 clutch waiting to be installed.
-upgraded shocks n springs
-just got a $900 box of every gasket, fitting, sensor, tensioner and fluid i need to replace in the swap
-all motor and trans and rear diff mounts have been replaced

heres what i have not purchased yet...

-LWFW billet steel probably 15lb
-rods- scat or IE
-83mm pistons- probably supertech
-ABA crankshaft- anyone have a good place to buy one?
-rod n crank bearings, coated, probably 034
-raceware/ARP head bolts and main studs
-Adjustable FPR
-fuel lines and rail
-2.8 manual trans
-GT3076r
-exhaust manifold and downpipe- im really leaning twards equal legnth tubular if the budget allows, otherwise an SPA mani
-tial 44mm v band wastegate
-high flow cat (stupid CT emissions) + test pipe for "off road use"
-in line fuel pump & gauge
-oil pressure gauge
-maybe EGT gauge as well


-tuning- im thinking unitronics BT file, injectors and MAF to match whatever it calls for, im probably going to drive down to force fed engineering in long island for them to dyno tune it and fabricate me some solid intake piping.

ive contacted bobQ about doing the head work, as soon as i decide on what i finaly want il drop it off with him. probably have him do the block too if im going to be up that way.

open to any suggestions, comments, etc. thanks guys.

[mike-2ptzero]

Thats BAT.

[ghost6303]

hey its a big turbo, even without the ass

[mike-2ptzero]

I am going to guess you haven't read any of Jakes post about his car sitting down at Force Fed. Good luck with that one.

[ghost6303]

i remember reading a thread about a guy (possibly named jake, i dont remember) and his car is down and the guy that was going to do the work is leaving for a few weeks? that one? i didnt know that was force fed.

other then that instance of it taking too long, i havnt heard anything bad about them, i know a few local people that had work done there and recomended them. never heard of anyone saying they destroyed their car which is a good thing.

would you recomend any other shop for tuning and whatnot within an hour or two drive of central connecticut?

[JumboBlack1.8]

Thank GOD.....a new member that knows how to search....well done sir.

For tuning, I think the only local shop that tunes B5's is Autospeed. I know EPL used to do it, but I remember reading somewhere that they've begun to focus more on B5 S4's and new audi platforms...but I could be wrong.....Someone else can possibly chime in on that one, since I obviously dont' know all the local shops......I would recommend Tapp if you were drive-by-wire.....but you would would have to run the huge MAF with an AEB, and its a bit of work to get it to idle properly..

As far as the hardware, go with the SPA mani and the 034 Downpipe (search SPA + 034 downpipe...its a VERY quality piece).....contact Issam at 034 for pricing

haha, that's exactly what I was thinking

Ghost, try calling farnbacherloles in Danbury, CT. They're one of the best shops/race teams around and they're a Uni dealer. They're huge in the Porsche world and apparently they're getting into the vw/audi scene since they were at waterfest. I would trust them with any car. Here's their website

i also found this place in Stamford a while back. i sent them an email and they never got back to me so i never went any further with it.

im drive by cable though i was considering tapp tuning, i think im going to stick with unitronics as long as a dealer is in the area.

I have had a very bad experience with ICS in the last week...

Anyways, Im Jake, and you should shoot me a pm with your number... I can do the whole build for you if you want, or just some piping... Plus Ill help you with your list

[Wizard-of-OD]

i read about 5.5mm thick is the way to go with the gear, depending on the rods, can anyone confirm this number?

usually 6mm
That is quite the list you have there but I would go with 83mm pistons rather than 82.5mm.

[ghost6303]

the only reason i was going to go with 82.5 is because a difference of 24cc's is pretty much none. what is that maybe 1 horsepower. id like to keep the extra .5mm of metal on my cyl walls just in case, they are pretty thin as it is.

Bobq suggested 82.5 because of that reason, and if there was a problem i could still bore it out to 83, but i would have to replace $600 pistons. or i could replace a $200 block. i think the second choice would be the way to go if i did have a problem.

so my reasoning comes down to more material=stronger and the difference in displacement is almost none so why not?

[A4Rob]

I just gave you rep points! Good work

Plenty running 83.5mm bore without any issues and thats while pushing the boost at 32+psi. The 1.8t block is not as weak as you might think. That 24cc actual does make a difference, if it wasn't people wouldn't go 2032cc vs 2008cc. Every little bit makes a difference. There are even people out there that wanted to go 2.1 liter vs 2032cc but there isn't enough room in the 1.8t block to do that.

[ghost6303]

i hear what your saying, and i have seen plenty of people running 83 with no problems. i havnt bought my pistons yet so i can still change my mind. i guess if it really does make some kind of difference i might as well go for the gold. why come this far and not go another half a MM.

how do you guys feel about rerouting the wastegate dump tube, i read alot of people say the welds will always crack, yet some people are able to pull it off. i really dont like the noise of a dump tube. you can just put a flex joint between the wg and the exhaust and that will prevent much of the heat stress right?

If you don't mind the sound, just run it open. I personally love the sound of the WG opening. I know Issam will tell you different

I am selling a Eurospec girtle kit if your interested. PM me for details.

[ghost6303]

i really dont like the noise of a dump tube.

yea im with Issam on that. why give police more reason to pull you over if you dont have to. that and i dont need to sound like an integra with a fart can, speak softly and carry a big ass turbo

[1fstavant]

sometimes i wish mine was re routed till you make little girls scream driving buy...

[mike-2ptzero]

well you would only really hear it when at wot and trying to run low boost. If you are going WOT and near a cop it wont matter if your running dump or not because he is going to notice you anyway.


dump at low boost = very loud
dump at high boost = not even noticed

But its not as simple as replace.You can sell them and the chances of having to rebore after 82.5mm is slim to none (unless your engine was built by a clown).
AEB blocks can be had for 100US today....go with the 83mm.

[ghost6303]

dump at low boost = very loud

just so im clear- low boost meaning 15psi and high boost meaning like 30psi? i guess the reasoning is that when running 30 the rest of the engine drowns out the sound of the wg dump?

i guess my preference would be a car thats as quiet and unobtrusive as possible. i understand quiet is going to be relative with this much modification, and i do like the growl of a nice bt audi, but if i can take a step to reduce noise with very little performance impact like rerouting the wg, il take it. i wont do it if i know the welds are going to have to be repaired every 5k miles though.

i work on the Berlin tpk, maybe some of you know where that is, and all day all i hear is civics with coffee cans welded to their leaking mufflers and other shitboxes making tons of noise with spinners that think they are cool. i dont need to be heard for half a mile, i just want power.

and if it makes all you nay sayers happy.. 83mm it will be

[Don Supreme]

Skip the 2.8 trans.

I would do 82.5mm, but hey I don't even have a stroker, so thats your call.

Regarding noise, if its real quiet, then you probably sacrificed a good bit of power to keep the noise down.

Yes, low boost being 15-20psi and high being 30+.

Have to understand that the more boost you run the less exhaust is going to be coming out of the wg since it will be closed more then when running lower boost. I ran 15-20psi on the street with a open dump and didn't really even notice it, that was done with a full 3" exhaust.

[Don Supreme]

Just don't build the dump tube out of 2" piping, because then it will really be loud *LoL*

[mike-2ptzero]

Yeah that would be very loud. Shouldn't need anything larger then 1.75" if using a Tial 44mm, even smaller for a 38mm. Can even taper it down since adding back pressure to the WG outlet is not a bad thing.

I have friend that have a 2" dump + 3" exhaust -- You really notice when the dump opens up

[quattro16]

Force Fed does not have an all wheel drive dyno. They just bought a new front wheel. . And they could just do a street tune which most of us on here could help you with.

[ghost6303]

Force Fed does not have an all wheel drive dyno.

ghey. i just read their site again. looks like they dont get my business. il give farn bacherloles a call but il worry more about tuning when i get closer to completion of the engine.

my plans are to be gathering these parts for a few months and have the engine ready to install by the time all the snow is gone next year. i may be going back to school for a bit in february though so, depending on money, it may even be pushed back a few months. i think im goin to go to school for this stuff so i can get a nice job at a garage with tools and most importantly a lift. an audi dealership would be the tits for some cheap parts.

Point me in that direction... i need ONE BAD>> to start my BUILD...

[dougyfresh]

You can talk to Tony@EPL. He may take on a project like this for tuning but I am not sure. You can also talk to Mark@ASP. I can ask him if you want since my car is down there right now. What is your ECU #?

If you need any help I'm right around the corner from the tnpke and can help out. I also have access to a lift in East Hartford where I do most of my work.

[xraycer2012]

I live 5 mins from the berlin tpke when I'm not at school. Maybe we can get an Audi GTG goin during the summer, there used to be a vw/audi meet on wednesday nights at the dunkin donuts across from hooters on the tpke. My new car should be done sometime during the summer too.

Anyways, I also forgot about a place in east hartford behind the row of hoffman dealers on connecticut blvd. It's called XX Tuning, they do alot of japaneese stuff, mostly, sti's and evos. They have an awd dyno there and they've just been growing and growing from what I've heard. Might be worth it to give them a call too.

[ghost6303]

i heard about them before, not exactly sure where they are. maybe il take a ride up there next time i get a chance.

your cars not black is it? ive seen two black A4s with some work done on them around the area, but thats about it. i saw one audi stopped by 2 cops outside burger king as i drove by, i felt bad for him, then when i passed i saw his bumper was on the curb. didnt look like he was in an accident, just like he took it off for some reason.

i would be down for a G2G. theres a car meet at duncan donuts next to circuit city in newington on fridays. mostly DSM and highschool kids though. theres another one that meets on wednesdays at taco bell, though its mostly the same crowd.

[ghost6303]

update: its been a while but ive been slowly building my parts pile. all i need are pistons and i can get the block machined and assembled....

[317ssayzarc]

Wait... What manifold is that?

[Don Supreme]

Indeed --- looks like an ebay special.. I hope not.

[Wizard-of-OD]

looks like ebay?

[pipe7284]

yeah, that mani looks like NO GO!!!!

[mike-2ptzero]

XS Power LOL.

[ghost6303]

hah i hoped someone caught that. i found that in the trunk when i bought the car. the guy said he replaced the wg and was going to put that on, but it seemed like a piece of junk so he didnt. its been my paperweight ever since.

[Don Supreme]

OK....

nice paper weight then *lol*.

[pac1085]

That's 5.5mm with Scat rods.
