Ive heard that the step tranny can only hold about 300hp and 310lb/ft torque? if this is true (if i were to get a turbo) is there a way to beef up the tranny to hold some where arround 370 hp?

You can't afford to go that fast.


Actually, I have heard of guys getting performance rebuilds on factory ZF slushboxes with improved bands, clutches, sprags, and whatever the hell else keeps an automatic from grenading. The problem is cost. A ZF reman runs $2k + and a performance slushbox will run at least double that if you can find anyone who will stand behind their work. Don't forget about a larger transmission cooler too. If you want a higher stall speed, plan on spending $1k + for a custom torque converter.

Bingo.

I have a Step and somehow I am not bothered by this. I see it as a way to curb my mod-spending habit. As of now, the car is more than what I need for track events. In fact, the first thing I did after installing ASA was to track the car, not to dyno.

You need a ZF 5HP24. This is what Alpina uses in their B10 V8s and V8 Roadster.
