big ass turbo in my Z. I'm not going to find another matching turbo to put in. I hate lag. But i have this turbo as a referance for the bolts and studs that's on a turbo. It's about twice a big as the stock Z turbo.. maybe a little bigger. I think he told me it's a T30 ther's this A/R 60 on the intake side and A/R 63 on the exhuast side. i could make this thing work but i wouldn't do it now.
