what are you guys running on your 7mgte's for turbo sizes? I'm looking at getting the SS tubular T4 manifold off Ebay for my 5M, and get a bigger turbo than my CT26. I don't wanna rev past 6,500rpm..... I just don't like Reving motors. so a 6,500 shift point would be ideal 7K total max. Looks like a GT 35/37 or maybe even a 40 would work. I'm also looking at turbonetics... what's the real difference between the 2 turbo manufactures?
