studdering problems, and high knock counts? HELP

[ezell4G63]

Ok , I just finished my swap. Car cranks quickly Idles perfect etc... I go to go down the highway and it drives fine. Once I try to build boost I hear a boost leak and knock count go to 42 and timing drops. The injector D/C is only at 76% with an o2 reading of .90. The car has been down for a couple of months so I am not sure what it could be. Even if I rev it up in the driveway at the top side of the RPM band it smokes a little. My mods are in my profile. I know nothing is wrong with the motor because it ran fine in the 91 body but I am haveing weird problems in the 90 body. Please help if you can or if you need more info just let meknow. Thanks, Kevin

For some reason you're probably not getting enough fuel. Do you have a Walbro 255?

No, I have a Buschur Racing Pump. I thought that was a possibility but with my injectors are running at 76% o2 is at .90 so fuel seems good. Thanks

OK, you will never believe this but this is what happens when more than one person works on your car. I noticed I was getting oil in the intake track. I check around and everything was pointing to the turbo. So I took the oil return line off to drain everything, whaile it was draining I went smoke, came back the pan was overflowing. So needless to say I had about 7-9 quart of oil in the car. I drained it out but have yet to see if the turbo is still screwed. Any way, moral of the story....Check everything yourself!
