My Single turbo and engine ran great in old shell , since i swapped this engine/setup into 94 shell , its been missing at 2600 rpm and gos lean 16:1 17:1 . only changes were done was evo 560cc to PTE 680cc and new coil pack . i kept stock Resistor pack what was on my 94 shell , so first thing was i swaped resistor packs from old 96 shell. Guess what ???? it fixed the problem
I changed my whole setup: piping, turbos, injectors, cams & cam gears, shortblock and intercooler and it seemed to fix the problem. I think it's most likely related to some sort of airflow turbulence issue that occurred with my old setup.
Damn that sucks man. I stripped some threads out in my lower plenum, prolly from taking the intake on and off so much changing plugs and gaskets, so mine has been down for like a month. I hope to get the plenum in this week and decided to go ahead and do the egr delete. I hope to be able to do more troubleshooting soon.
