I dont know where your getting turbos at. Believe me I ve had people come up to me and tell me how much theve spent on mototrs turbos and all kinds of crazy shit. bottom line ball bearing t3 t4 go for about 450$ in cali. I just feel alot of people are getting ripped the fuck off. These systems are so easy. Ive known people who complain about buying parts for thier cars(and i think to myself jeez I just spent 700 bucks last year on a tool box). but anyways your negative comments are taken and appreciated. By the way my junk ass set up runs at 9 psi normal and around 16 psi with the boost controller on. what kit can do that? late mike
