I just realized my wastegate was disconnected(they threaded it and put a nut to increase length). I never knew what is was like to drive "under boost" it would always hit 7 psi then start pinging bad. So it was always balls out or no turbo. When I hooked the wastegate back up I can drive under boost now and it is awesome, but if I nail it under boost if coughs and pings at around 4000 rpm, but if I give it 2/3 to 3/4 gas it will rev higher and keep going to 6500rpms.Car runs great. Do you think I need a better fuel delivery to the injectors? I don't have a fuel pressure gauge. I have the stock rail and an aftermarket fuel pump(doesn't look hi perf.). Other than that the car runs great. It's a 72 with an 81 turbo and 77 electronics (ecu,turbo afm,dash, interior), n/a distrib., 60mm t/b. 2.5 exhaust, t-5, r200 open diff. 3.9. I just got some fuel rail stock that is huge. I plan on making the rail myself and keep the barbed injectors. I also am not sure of the injector size(they could be turbo stock). I just got a megasquirt 2.2 and edis and intercooler, plan on putting that all on the winter. Now I'm wondering if all I need is better fuel delivery.
Thanks Chris
