Okay I've been looking around for a long time for a good turbo setup for my car. I've found it pretty mind bogling. Can some of you guys please tell me what would be the best setup for my 90 s5 TII? What trim? What size wheel? and so on. Also could you please give me a brief explination of all these things? I was thinking about going with an HKS t04e or a turbonetics rebuild to a 60-1 hifi. What do you think? Would either of these still leave me with good streetability, but give me some high power numbers? I was thinking that when I was finished with the car that I could atleast get about 375rwhp out of it. Do you think either of these could push the power numbers that I want. Just for your info I was planning on doing a mild street port with 3mm apex seals after getting the turbo. Which means I would be running it on a stock motor(2mm seals, no port job) for a little while at about 10 to 13 psi. I know that I probably wouldn't put out 375 rwhp like that, so please tell me what's the best one for me. Thanks.

i had an upgraded 89turbo (its a t04 compressor on the stock exhaust side) on my t2, and i loved it.
stock lag, and it had power as far as i wanted to rev it (no dropoff like stock). its now on a ported motor and it runs out of steam at about 6500 rpm.
i was running 10-13psi and it was fast (i think about 250rwhp?)

That's cool. Does anybody know anything else that I should consider?
1. do you need to keep the airpump?
2. do you want a good street setup, or do you want to drive it to the track and run 11's?
3. how much $$ do you have to play with, manifolds and external wastegates get pricey ($1000-1500)

airpump is gone. I'm thinking mid 12's would be good. Keep in mind that this is my daily driver.

Mid 12's SHOULD be able to be done with a stock upgraded turbo. They're good for close to 300 RWHP if everything else is done right. That would probably be around 17 PSI or so. A custom setup would be able to yield over 400 RWHP at 17 PSI.
