Going on like 8 months now here are some pics of where my project is at. I don't get much time to work on it since I'm a full time student 2 hours away from the car. I got the motor in and it was running good but would break up and just backfire once I got into upper rpms. I'm not sure what was causing this but I think its because I had too much fuel pressure with a walbro 255 and no FPR, but I'm getting a FPR for it soon once I have the money to spend. Any thoughts on this? It could also be the turbo being bad as I was driving the car one time and the wastegate line came off and overboosted but I caught it watching the boost gauge since I was doing testing. Would the ruin the turbo? Ever since then I am getting an oil leak on the turbo side it seems to be coming from the bottom of the turbo but its not any of the lines so I'm confused about that also. Any input would be great, I'm no where near done with this thing but I thought I'd share some updated pics.
