Ok, I just swapped a redtop Sr20det into my s13. Its a stock motor with a Gt28r turbo, HKS 555cc injectors, 255 fuel pump, and an RS Enthalpy ECU. I just got the Ecu back from Enthalpy. The car starts immediately and idles beautifully. When I rev it it will not go past 3000 rpm without misfiring and dropping back down in rpms. Since I havent gotten to the exhaust shop yet its basically dumping out underneath me so I can smell its very rich like unburnt fuel. I believe this is causing my problems. Does anyone have any ideas of why it wont rev like this? And yes, I have been researching. Thanks for any input!
