Slow building boost

[andrewjscott]

I know somewhere on this fourm theres got to be an answer, but searching turned up 500 results, most of which had nothing to do with problem diagnosis. I just finished a rebuild and everything went really well, except now I can barly build boost. I get maybe 3-4 psi and it takes forever to get there. Any ideas where to start looking?

yeah, i thought about it. DSM's are hard to come by here in the yards...and stuff is expensive. 45 bucks for an ashtray, 175 bucks a piece for dual piston calipers, 900 bucks for a front bumper that is damaged...I may have a hard time cuz theres only about 2 engines left on the island, i'm actively checkin out the classified, but for the time being...i'll continue to tinker with trial and error.

I am having the same problem with my car, which is a 90 gst, so i am going to try and follow what u do. Have you had time to fix your probelm? I know the spring is gone on mine too. The question that i want to ask everyone, and to save money for the both of us, can the spring be replaced for a small fee or do you have to buy a whole new wastegate or stock exhaust manifold with one in it?

P.S I am a newbie to the whole dsm world but learning a lot from this site. I plan on rebuilding the one that i have back to factory specs so i will be learning a lot from it and will have a lot of questions and answers.

I will come down in a couple weeks and help you out if you can't fix it.
