Best Audi for 5 Cylinder Turbo build?

[animportant]

Hi guys.. I currently own a B5 S4... Always an idea in the back of my head to build an AAN car or something similar if I had the money.. My apologies if this has been posted before, but what do you think the best car for the swap is? I have attempted to do research on each of the older models, but haven't really seen comparisons. Interested in weight, handling, and the potential to be a low 10 sec or 9 sec car. Thanks! Should be interesting. Are the coupes the way to go?

[AudiCoupeGT]

The Audi 90/Coupe Quattro are popular for the AAN swaps. Even some of the older B2 platform cars really improve with the AAN swap especially since they are a smaller body with a fairly light weight.

[pilihp2]

it really boils down to personal preference.
A urs4/s6 or a 91 200 have the motor already there and ready to go. No need for a motor swap. If you want a smaller car it just depends on what you want. An older car like a b2 4000 or something of that nature is going to obviously be older and a little bit more basic. If you're used to your s4 and want something newer on the inside and out then go for a 90 or cq.

i eventually want something really "raw" with lots of "soul"

[pilihp2]

4000's are already pretty raw. Wont take much to gut one if that's what you're looking for. A lot of owners will tell you they're quite possibly the best car ever made. That's obviously in the eye of the beholder but I sure do love them.

[Ruffiano]

i think it comes down to budget.

if you truly want soul, go with a UR-quattro.
if you want the soul but want to be cheaper, go 4000
if you want soul but don't want to deal with rust go with a 80/90/CQ
if you want soul but don't want to swap an engine go with the 200 20v/URS4/6

These are also listed in order of weight.

Thanks Everybody! Ruffiano, you my friend, have just been awarded 20 points!

[Ruffiano]

for what it is worth, i swapped an AAN into my CQ. it is now a built up AAN and should be putting down 400awhp when it is all tuned. easily upgradeable to more by just swapping turbos.

My personal vote goes to the Coupe Quattro, although we've built and tuned just about anything you can think of with an I5 20VT.

Here are some pictures and videos of the old 034Motorsport I5 20VT Coupe Quattro.

Laszlo, do you still work for 034?
I called them few months ago, needed help with a part and I wanted to speak with you.
Someone said you are no longer with them :S

I'm still here! I left for about a year to deal with some school stuff, but I'm back.

I don't do sales or phone support anymore, but I'm definitely here.

I have a UrS4 fully built. Just finished my build and thanks to 034 she's running great. I'm actually getting some maintance work done now but I'll have it fully tuned and running 100% in 6 weeks and I'm on Long Island, I got the car stock for 11k (literally the cleanest in the country) and put around 25k into it. Car will be around 525whp on E85 according my tuner.

Good news!

And I'm sure you would help out a fellow Hungarian guy over the phone ;)

Koszonom!

It is not going to make 525 whp on a 30r. With E85 and the best manifold out there including some head work, it took about 28 psi on an HTA 3582 to make that kind of power. You'll need a bigger turbo. Remember the drivetrain losses on these things are crazy.

OP, the best car to do this with is by far the urQuattro. There is no better Audi in terms of driving experience. The order listed earlier really is good in terms of how they are to drive. The UrS4 is by far the most comfortable and advanced, but it is heavy.

Stupid question -

What's the most you can push out of a 5 cyl without engine work and head work?

I really want something I5.

If the 5cyl mean a 3B (200 20vt) or AAN (urS4/urS6) then around 400hp, they said.
The weakest point will be the rods.

[coolgraymemo]

At the crank or the wheels?

[Ruffiano]

i was making 380 tq at the wheels and just under 300 hp at the wheels and with that setup i bent a rod and shot it through the side of my block. I think tq is more of a killer then hp.

Here's a similar question in a different direction. What's a mild streetable build amount to in terms of engine selection, turbo, management, etc.

I'm interested in a CQ but would like something more along the lines of S2 performance. Is an S2 swap easy or even easy to come by or am I better off going aftermarket on a stock CQ?

I recently sort of "compiled" the pictures from my CQ->S2 project in one little thread:
http://forums.vwvortex.com/showthrea...and-why-i-suck.

I don't think it is "easy" to come by, but i think it is very possible and it all comes down to your budget. I had a tight budget on my build so i sort of had to wait for deals to come along to buy things and i acquired pieces over about 6 months. The trick is you need to be watching foreign enthusiast websites or make friends with people on the other side of the pond to help get parts coming to you, relatives or friends in other countries makes it easier to have things shipped to them to be put together and shipped over all at once saving on shipping and such, also many foreign people don't like to deal with getting international shipping quotes or getting foreign payments (Nigerian princes).

The actual building of it is very straight forward and doable if you are using OEM parts. If you look at the thread i posted you'll see pics and some explanations. There are a million ways to do it and it all depends on what you are trying to have in the end. I built mine with 3 main things in mind.
1. Simplicty/Time, i have seen hundreds of people try to swap 20vt engines in their cars and seen so many take years to do or give up and sell it off half done.
2. Budget, I didn't use a dime from my day job to finance the project so i had to sell car parts on the side to fund it. Basically i bought a donor car and sold off the parts from it to pay for the cost of the donor and to fund extra parts.
3. Upgradeablity, that might not be a word but you know what i mean. I wanted something that would be a good base that i could get up and running quickly and for reasonably cheap, but would still have the capability of being upgraded in the future without having to redo everything. (example: I used the oem s2 wiring harness because i could get it running with a stock ecu, but there is also a plug and play aftermarket ecu that i could upgrade to without having to re-wire the car, vems)

OH MAN. I can't let Ruffiano steal all the glory for AAN swapped cars!!! I gotta say, I've been in a really well built AAN powered 4kq and 80/90 and both are really awesome cars. I am still in progress with my build, so I don't know 'exactly' what it will put down. BUT IMO as good looking as a CQ is, 4kq is where it is at for me! :) Here are a couple pictures of mine (in progress)

[Eurotuned_A4]

I plan to do either a aan or 3b swap into my UrQ someday after i restore the rest of the car. I cant wait for it!

[Rejmow]

Go "B" platform, 80/4000 the older the better. Go GT28 or bigger, and then build the car around that depending on how much you want to spend. You should really get it to move if you get it light enough. Or if you want something newer, find a B4 Quattro sedan. I5 it, and start building yourself a S2/RS2 sedan. Imo one of the best looking Audis.

B2 sedan, looks awesome. Decent power ;)

B4 Sedan, just.. Beautiful

It would be wicked to see someone swap one into a B5.

Yeah I know people are swapping VR6s... so let's not mention that... haha.

That's exactly what I've wanted to do to a CQ after years.

I have a question. Where can i get a good 20v turbo engine to drop in my 86 coupe gt? And how much hp can i expect to safeky push through stock internsls on that engine?

watch ebay, audifans.com, and motorgeek forums, those are general the best places to find it, expect to spend 800-1000 for an engine. Stock internals handel around 300awhp and or 340awtq

I got lucky. Browse craigslist every few days. Been searching for some stuff for my UrQuattro because you never know what pops up and/or when. Today I bought a 1991 audi 200 20v for $775 locally. The car runs and everything. The body is very damaged and the left tire is pushed back into the wheel well because of damage due to hitting a curb very hard....but $775 is a damn good deal for a 175k mile engine/trans/whole car. I should be able to part out what I dont need too so even better. The car cant drive on the street safely, but it does enough to get into my garage so I can yank the engine out for the future swap.

Sinpsyochotik, over on motorgeek.com there are 2 AAN engines for sale. Here is the link, not sure if they are still available or what they would cost to get shipped to you. Id guess $1300-1500 total. At least you would know its coming from a good source. http://www.motorgeek.com/viewtopic.php?f=4&t=48657

I'd not do this unless you enjoy spinning front tires. Get a quattro and proceed.
