Well considering that my car has about 140k on it, I think that I would have to rebuild alot of the engine to handle the turbo. The high mileage was the reason I was looking into a h22, but for that much I could prolly put a down payment on an IS300 and save up for twin turbos for that... Hmmmm, IS300 twin turbo... MMmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm.
