Wow, I didn't realize ZPI was still around. I was one of the first tCs with their kit back in 2005. I use to frequent scionlife and clubsciontc. I had constant problems with their kit and had to rework alot of it myself. They even did the install themselves. I tried telling alot of the owners about them but no one really listened. My setup did the exact same thing. Let me know if I can be of any assistance and good luck on your sale!
LOL, ive try to get the turbo runing straight but the seals just dont hold i have no idea what the hell is wrong with the 20g turbo cause the 16g did not have that problem this dude down at youtube.com his name is rythmnsmoke is also having the same problem with his and does not want to admit that the his problems oh well, what im trying to do is fix the seals and sell it to a DSM owner and hopefuly he will better luck with it, and im keeping everything else cause im gona need for later when i buy the Turbo toyotas kit for a built motor, but thanx anyways.
Ps. do you still have your kit and or car?
