Ok, been a long summer for me, got my on3 turbo kit this summer, but been so busy havent had time time to install till now. Got a few problems that I hope someone can assit me with. I have a appt. woth Piedmont Custom Motorsports Thrusday morning for a dyno tune but Like i said theres a few issues.
My wastegate stays cracked at idle and never closes all the way. I have installed the fire ring the right way and have even bought a new wastegste(OBX). The one that came with the Kit and the new one act the same, cracked at idle. Ok, started off using vacuum sorce from the line that used to go to EGR, boost gauge never moved. Ran this to my wastegate, bov and boost gauge and nothing. SO then I taped the plate where the EGR used to be and installed a brass adt. to hook vacuum line too. Got lots of VAC on boost gauge but wastegate staying cracked and the bov are staying open.
So now I have welded a bug into the coldside pipe that hooks to the turbo and tapped that to reference vacuum line to waste gate and boost gauge, still stays cracked, never build any boost and gauge moves a little. BOV still open all the time, if you loosen vacuum line going to it, it will close. Cant seem to figure out what my problem is, how I could I have 2 wastegates that are different but act the same. Any help would be great because it will save me time at dyno if I have this worked out before, so they dont have to figure it out. THANKS
