I've tried a search and no one is using an SI, all are using HF or DX or STD.
Still the only thing i found lost me in the responses.

So here are my questions, if I'm swapping D16Z6 into a 90 SI hatch.
And I want to use the p28 ecu, what wiring do i have to do?
Just have to modify the wiring harness right?
Add a few wires going from ecu to activate the Vtec or is there more to it then that?
Since the car is set up for MPFI there shouldn't be any big changes there right?
Well thanks for any info.

 

it won't match color for color, but get a manuel, like a chiltons or something like it (not a haynes) and wire in the obd1 ecu plug one wire at a time to the right sensor.. will take a few, but it's pretty easy
