S4NA to S5TII Swap: Runs Weird, Runs Rich, Won't Idle
okay here's the deal:
I have an 88gxl s4......we put a 89 turbo 2 s5 engine & trans.(incl. s4 ecu, wiring harness, spark plugs etc.)
The car starts but sounds wierd like its not right... It's running really rich...and If you let go of the gas the engine dies...So it's not idling...
Can anyone help me and tell me what the problem can be?? So I can get it on the road asap. thanks.

im using the s4 injectors on the s5 engine because im using the s4 ecu and harness...im basically making the engine think it's and s4 but it's really an s5.

That's only on the s5 n/a, not the TII. Besides, on a stock turbo there really isnt much point in going past 6500rpms. The turbo cant keep up and boost falls off.
