I am swapping in a d16y8 engine in my 90 si. I'm told everything will bolt right in and i can use my stock d series tranny with this engine only thing is is that this engine is a vtech engine. I was told i will need a vtech solenoid and a vtech ecu. what else will I need to have for it to run right?? What about the fact that the 90 si is obd-0 and this new engine is obd-1??
