Turbo or Trans

[Rich1985GST1997]

Ok im so confused and you all have helped me out tons of times. Ok the car is not shifting or pulling past 3000rpms, my first guess was the automatic trans was slipping. It stills shifts to all the gears, but it feels likes its slipping, I also noticed the the boost is not going past 5psi, and at 3000 my t25 is always at 10psi. When I put the Upper IC pipe on I noticed oil in it, so my next guess is that the trans is fine and its the turbo that went out. This is my first DSM so im at a loss. Im trying to figure out if its the turbo or the trans??? Any ideals???

I would take out your turbo because if you can't boost past 5psi and your norm is 10psi and you can shift into all gears it has to be something do to with your turbo if there is oil in your fmic.

remove the pipe and check for turbo shaft play , and then take it from there

check also for boost leaks

good luck

Yea something isnt right, its like the engine isnt getting air, 7psi at 3000rpms and bogs. It feels like the blade has scraped the inside a lil, but the blade still moves freely. To be honest im not a big turbo guy so I have no ideal. There is oil in lower IC pipe and in the turbo when I took the Intake off.

Thanks
