I am not trying to justify my T67 set up!!! If I had a SR20 I would used a GT35R. I had the T67 with a 93 exhust side and boost was coming in around 4000rpm yes it was laggy, but I know how to drive the car, this year I am going to run 68 exhust side so boost will be much faster. I am into drag racing, so my setup will be alittle bigger.
Anyway your build is sweet!!! did you do dual valve springs? Also did you balance your parts? I hope you did.
