aight im still working the kinks out on my sr swap. Its a s13 sr blacktop, full exhaust except for a 2.5 inch apexi n1 evo catback, stage 2 clutch, fidanza flywheel, greddy m-spec, greddy rs bov, boost and oil pressure gauges, greddy prof B spec II ebc, apexi turbo timer etc. The car seems like its running fine but when i get on the throttle its smoking like crazy..before one of my injectors werent working so number 2 cylinder wasnt firing. I jus got my new ones installed them its running better but like i said its smoking when i get on the throttle, iim thinkin its my turbo but its still boosting..anyone kno what the problem can be? My turbo exhaust gasket is blown..Im going to change that when i get out of work today but would that make it smoke like that?

Does it smoke when you hit boost?? Off boost?? If it smoke when you start boosting, its probably the turbo......seals perhaps

In my expirience with blown turbos, you should expirience some more symptoms than just smoke. On mine, it would sputter badly when I would cruise with my foot at a constant throttle. Mine also put out a small amount of smoke at idle. Hope that helps...

Yes mine still spooled and all, I had just blown the seals so I was getting oil in my intake charge. Take off your hot pipe to your intercooler and see if there's any oil in it. Then you can see at least where your problem is originating. If there is no oil, your problem is in the motor itself. If there is oil, it's most likely your turbo.

You should not have oil in there. There is no way that the turbo could throw oil in that pipe. I have no idea why there would be oil in there.
