The Greddy T-88 is NOT an 88mm turbo, the supra guys swear by this turbo, it does have a very big exhaust wheel (did I mention very very big wheel) One of the reasons they like it so much is it seems to be indestructable. the supra guys have made upto 8xx HP with this turbo. Btw it is a mitsubishi turbo and the comp wheel is about the size of 74.
