If you don't want to blow **** up, don't waste your money.
The stock ECU is CRAP is trying to control something like this, and I don't think you can afford the $1,000 minimum + another $1,000 to get it install and tuned for an aftermarket EMS ECU.
Please folks, don't argue with me on the stock ECU - go find BDC.
You see, this **** gets expensive in a hurry.
And, no that GReddy turbo kit does not fit on your non-turbo FC.

Turbo swaps have been covered in other post, but in my oppinion you really should just get another car that is already turboed. it is way more work and money then you are going to want to do/spend. as you have to convert the engine, wireing harness, computer, tranny, driveshaft, rear end, axles, ect...
Just try to find a Turbo II
I am not saying it cant be done, my best friend converted his N/A over to Turbo II but it was a lot of work.

whats the problem with turboing a s4 if the s5tII had the same compression!? i thought it was lower.
on a similar note, would 3mm seals be considered decent for prepping an s4 motor for turbo power?

89-91 Turbo = 9:1

As far as turboing an NA, I see no problem. Just little issues like LIM clearance and such. Leaves it up to you to do the figuring instead of buying bolt-on stuff that's been working on the original turbo cars forever.
