    Welcome to the GMTC! From what I remember, the '87 and '90 model diesels were totally different. Good luck!

    I want to thank everyone for your help the 90 manifold bolted right up the motor runs a lot better i ported the manifold and turned up the pump . I also added dual 2and half inch pipes this is a huge improvement over the gas motor

    why not just get a 96's exhaust manifolds with the turbo on it and do a turbo? The manifolds cost only like $500 with the turbo, then just take the rest of the turbo with it.
