Ok after my car survived the dumbest thing I have ever done. see other post.

Im only getting 4psi from my T28 with some lagg I wanted to bounce some ideas why off you guys.

Im using a T28 from a nissan 240 dual bb baby. mated to a hand ported t25 exhaust side so its a direct bolt on.

1)Wastegate Im running the nissan one(fit better) im not sure what they are set for. I dont have a Boost Controler yet in a day or two I will.

2)boost leak? new turbo, fmic all that crap something is loose.

3)its just a bigger turbo a t25 at 11psi is a t28 at 5psi?

4)I suck at hand porting and made the induser wheel hole on the turbine housing too big?


Im thinking #1 or #4 what about you guys
