I installed a used turbo and now I've got absolutely no boost, the needle on the boost gauge never leaves the vacuum side of the dial. The used TE62 came with a stock style wastegate that I decided to use because it seemed to have a different bracket that fit the larger compressor housing. I'm certain all my vacuum lines are correct from the solenoid to the compressor housing and wastegate. My only concern is that the puck in the THDP is too small in diameter. I took a digital caliper to it and it looked like it would be close, but should completely cover the hole on the exhaust side of the turbo. I've got the wastegate rod tightened down to the point where I would think it would be running too much boost.
I was running a TA-49 before the swap, but I roasted the 49 so it's in pieces right now. I'm not sure what else to check, am I missing something obvious? It's a stock block car with basic bolt-ons running a Turbotweak chip.
I'll post pics later once I get home of how I've got the vaccum hoses routed. Thanks in advance for any suggestion you guys may have.
