my turbo started to only boost liek 4 psi, and it takes forever for it to spool. i am thinking my turbo is blown, how do i tell if it is, and if so what turbo should i buy to replace it.

just check your ic piping and couplers for a crack or leak , poped hose...b4 you buy new turbo.
pull your accordian hose off the intake of the turbo and inspect the blades for damage and the shaft for excessive play, ive heard if you can easily see it move, its worn out, but im not sure this is good info.. look for any metal scrapping or rubbing marks inside...

suppose there is other causes possably if the motor is not tuned properly or the exhaust is plugged but thats bout all i got.

it would boost to like 80 before jsut fine, but now it slowed down, and it will only boost to like 4 maybe 6 after a long ass time.
