I didn't know of any other topic to post this at. My friend has a '92 200SX turbo and there's a problem that I can't figure out. :banghead: He is bogging out until about 3200 RPM (where his boost kicks in). He has oil on his throttle body and in the intake tubes (I know this can't be good). And he has white smoke coming out of the exhaust on hard acceleration (not a lot, but noticeable). If anyone has any advice on what is wrong with this car, it'd be greatly appreciated. FWIW, the car just had a new turbo put on by the previous owner. :helpsmilie: Thanks guys.
