My problem is with a 2008 EJ20 engine in a 1993 Subaru Impreza SW manual 4x4.
I'm assembling an EJ20 engine from a 2008 Subaru Impreza (naturally aspirated). It has a cylinder head from an EJ22 Phase 1 and a crank trigger wheel from a 1995 EJ20 Phase 1 Legacy. We set the timing and tried to start it. In my opinion, the original module may be out of sync since it's from an EJ18. The engine is out of sync with the bottom end because it's sparking with the valve open, and there's fire coming from the throttle body. Should I change the module and wiring harness to fit a 1995 EJ20, or install an aftermarket ECU like a FuelTech?
