I have a '95 RS, I'm all motor now but will like to turbo charge sometime soon. I'm saving up a lot money to buy a Hahn stage 4 or 5 turbo charger. I checked out the website to see what mods were needed to be done to my car along side installing the turbo. It said to upgrade the clutch, but the thing is I have an AUto tranny. Am I gonna have to convert to a manual tranny? or are there auto tranny upgrades that can handle a stage 4/5 turbo?

for the auto tranny to hold up, you will probably need to rebuild it, check out www.levelten.com

hhmmm,Iv'e been rolli'n w/ 16 and as much as 18 PSI for awhile and there's no signs of the tranny dyi'n on me.

Stage 4 or 5, try level 10s PTS kit.. you might want to consider sending your whole valve body to them also. You should be fine with just a PTS kit though. Oh yea get the blue clutch option if you plan on driveing it alot and the red if its just for the strip, if it is just for the strip you might want to consider a TQ converter as well.

Level10 has done extensive testing on our AT at 360hp. Their conclusion is that it's safe up to 400hp.
