Built gsr turbo....the car sat in my building for awhile maybe 5months and I didn't start it much...the battery died a few times,charged it and it would work(optima) anyways I had to rebuild my transmission due to stripped countershaft and FD. I just recently put the transmission back in the car and EVERYTHING IS RIGHT! But the car didn't want to start,got it to start,wouldn't stay running...figured it was bad gas...put a mix in it 1gallon of 100 and the rest 93(tuned on s100 93octane) so I kept giving it gas and reving it a bit not high though...took it down the road and it cut off,got into boost it would sputter,engine would shut off. Id start it again and it sputter and jerk like it wasn't getting fuel,car shut off again,I started it and all of a sudden it sounded like it was missing badly.....like a plug wire came off,it didn't I checked,still acted stupid,then wouldn't rev past 4,000rpm! The engine started shaking very badly during idle looked like it was trying to jump out of the car. I'm lost and I hope I didn't **** the motor up.....PLEASE PLEASE HELP WITH ANY SUGGESTIONS
