turbo problem
ok so about 3 months ago i was talking to you guys about my car leaking oil. so i found out the head gasket was getting readdy to go so i decided to replace it (after getting a $700.00 quote) so i figured i can do it myself so i ordered all of the parts(head gasket set, new water pump, timing belt kit, exhaust manifold-old one was cracked) so we put all of this stuff on and now in order to get my turbo to blow of or even run i need to get it into high rpms 4000 plus do u guys think that this is because turbo gasket (the one from the exhaust manifold to the turbo) because that is all i can figure out- its not timing she is running great. or could it be the turbo has gone bad. what ever it is i would really like to know i am so tired of working on this thing i just went out and bought a wrangler so i had somthing to drive while my gst is out of commision
thanks for any info you guys can give me

RE: turbo problem
Wow, thats wierd.. Do you get full boost at 4000 rpms? Or is it just boosting a little? If your just getting a little boost, then you prolly have a vacume line hooked up in a wrong spot, or a bad boost leak..

RE: turbo problem
you might want to check your timing too. If you didn't line up your timing marks correctly it will through off the rate the valves will open and close and thus cut down how fast the turbo can spool. My buddy had the same problem and after checking to timing marks on the cam gears, he was a tooth off. We adjusted it and the problem was fixed.

RE: turbo problem
it was reused and i had to take off the mainfold a few times but i replaced that gasket twice because it stuck to the cracked one when i took it off. u guys think that would cause the pressure to not build up in the turbo?

RE: turbo problem
i cant really see it causing that big of a problem though. Because its not gonna leak enough. Does it feel like your car is not boosting at all until 4000 rpms. Not talking about the BOV. Just going by how it feels. Because if its not you probably have a boost leak. I would check the connections for the intake and IC pipes. Make sure everything is hooked back up correctly.

RE: turbo problem
idling has nothing to do with it. My buddy had a great idle. His turbo just didn;t spool like it was supposed to. Since his timing was off we had to fix it anyway and it actually fixed his boost issues (exactly like you are having). That is the only thing we did. We didn't fix the vacuum lines or anything, and that fixed the problems he was having. So, like you said, it may be just your timing. good luck brother. If you need anything else, don't hesitate to ask. we'll help you as much as we can.
