talk to carbonis about your turbo kit and what his options are for his USDM IS300... he was thinking swapping a Supra motor and tranny in, but its a big and expensive project... if you're well versed in turboing the stock motor then i'm sure he'd love to talk to you about it... but it might be different motors between the US and Japan-- i really have no idea. maybe you can bring him back some goodies
(or maybe you can bring me back some goodies!!)
