I see a Electromotive EMS with custom harness for sale for an MR2. If I get this, then could I just get the 3SGTE engine and not need to worry about the other parts needed that come in a front clip? This is coming from a 5SFE on a Celica GT. The EMS also comes "with trigger wheel,coil packs,magnecor spark plug wires,850cc injectors with custom made fuel rail made to fit my 2nd gen head,Custom made wire harness for my mr2 will fit perfect to any 2nd gen motor srt8 bolt on."

If I had this, then would I still need any of these parts from the sticky? "3rd ECU plug, AFM, ignitor, coil, injector resistor pack, fuel pump resistor, fuel pump relay, turbo pressure sensor, air intake piping, and probably some other stuff".

Seems that if I had this, maybe I could just get a 3SGTE engine and do the clutch disk work to use the 5SFE or the different tranny.
