: I am doing that because it will be the daily driver of the two. The 94 and 92 will have a few things in common but manifolds and turbos will be completely different and the 92TT will have a stand alone management system....I predict in the 850-900 rwhp range....just hope it all works out. Still looking into the fuel system and a few other things. It will have significantly larger turbos and a not stock tranny .....but it will still be able to run in the street class :)
I don't know if you have or haven't but the difference is "spoogable". The high flows are sweet. Let me know if you haven't seen them, I will try to track down a pic of one.
