Might want to talk with DSMJIM he is running a t3/t4 turbo on pump at 12.56 right now @20 psi. Its a sweet setup and I've had the priviledge to ride in it and was very impressed, impressed enough to order one about 3 days later!
BTW Im AWD but automatic trans for the time being
I have a 5 speed donor car ready to swap
and I run the translab shift kit and alto end clutch and its a HUGE improvement over stock.
