Audi S2

[TwinTurbo02]

Curious if anyone can tell me about this bad boy. I believe it has the 2.2 I5 Turbo. One of my buddies is moving to the west coast and is looking for a car and i showed him one and he fell in love. Curious about how hard these guys are to find. Any help would be great, Thanks.

I thought they were not available in the states?

[urS6Plus]

They arnt, but I have seen coupe quattros converted to S2's, They are rare here in the states, but popular in England. These bad boys haul ass.

So I guess we are talking about turbo CQs (or eS2s or CQTs or ?) There are a TON of ways to get this done. You could swap in a AAN or 3B without much trouble (things need to be re routed) or you could TC your 7a.

My CQT was making ~8psi and 180whp at sea level (on 034's dyno it is now at 5280' and a bit lower then those #s). It is a blast! In the next few months I'll be working on a bit more power from a S2 IC and E85. Not sure where that will put me but eventually I'll drop the compression and do some other things.

[Spykce]

To turbo the 7a engine, don't you need a 10v bottom end to lower the compression ratio? At least in my limited reading this is what I have heard, along with some machining to the head for water passages?

[Mcstiff]

To turbo a 7a engine you need to bolt a turbo to the side and hook it to the intake.

To not blow up a stock 7a with a turbo you need conservative tuning.

Thanks Guys, i think this is the motor he wants ?? Its and audi 80 but i think they put it in the s2 as well.

So that is a modified 3B; we got them in the 1991 200 20vt. For this level of performance you may as well build a 7a as the parts you replace (rods, pistons) are the main differences btw the 7a and the 3b or AAN. I would check out 034 Motorsport.

wow i want that engine

[TwinTurbo02]

yea, personally i think it could be one of my top 5 favorite motors. It punches out a shit load of tq and hp and doesnt weight anything. Plus Plus kid!!

[Burtonrider1002]

pix?

[Mcstiff]

Of?

[JoeM]

034 sells CR dropping head gaskets for 7a turbo projects, I am about to get started with this on mine.

[Mcstiff]

CDHGs are great but you can TC a stock 7a. Nate at 034 was the PO of my CQ. The parts on it were the prototype for their 7a TC "kit".

[PRY4SNO]

034 built a 7A to over 800 hp for their latest challenge, the Castrol engine shoot-out thingie.

After reading that I figure it's silly to spend the time/money on a 3B/AAN compared to rebuilding what I have already.

[JoeM]

Tactic you have any specs on your build?

And the 034 kit is about 4k with no IC, MBC and just a chipped ECU. Doesn't even have a DP in the kit.

I am happy with mine but I did not pay $4k (Came with the car).

[JoeM]

Good deal if you bought it with it. When I inquired that is the figure I was given, I appreciate them coming up with unique parts and understand R&D is spendy, but just is out of my range and seems like a DP and IC setup would be there for the price.

[Mcstiff]

Yeah not coming with a DP seems like a fault.

It is pretty fun WO a IC but my plan is to install a S2 IC sooner then later. Adding a DV was easy. I am running Ic and working on refining the tune but I have not tried the chipped ECU that I have.

If I was looking at going 20VT and had the cash it is the quick way to go. Swapping engines is not quick. With a CDHG and IC you can get great power from the 7a (with a good tune).

Over the summer I will be seeing what can be done at each stage (WO IC, W/ IC, eventually with IC and CDHG).

Name's Dustin, btw.

It's pretty complicated... rather involved, and technical.

Specs follow.

































































Stock.

;oP

For mods, see signature... that's how I bought the car this past fall and am now just starting to sink my teeth into the car.

A build thread will be posted soon, with the basic initial maintainence it needs also included.

You are looking for something like this

This is Jimmy Pribble's eS2 he used his own totalled S6's AAN motor and built this beauty from the bottom up!
