Hi, I'm in the middle of building a 1989 z31 turbo. Originally it was a n/a automatic. I have now put in a 54,000 miles turbo engine and manual box. I'm wondering from reading other threads etc what steps are needed to get 350bhp. So far I have a boost controller, 3 inch exhaust, induction filter, and intercooler. From what I've read I would be safe to run around 15 psi with this set up, but not sure what bhp I would get. A lot of the tuning guides are from the USA so the fuel is poor and their stock cars have different cams and stock bhp.....any advice is welcomed!!! Cheers
