i have a 92 hatch dx and im swapping in a d15b2 cause its the only engine i could find. i have a p28 ecu obd1 and the d15 is obd0 and non-vtech. i matched color to color from dizzy to engine harness and had two wires left on the harness. now the propmlem I'm having in the car is it will start and run ok but hitting the gas bogs it out if over 3k rpm.

 

I don't think the wiring is the main issue. Why did you not get the correct ECU for that engine?

 

i thought the p28 would work on just about any honda engine? and i dont have the money.

 

I also took my intake of the old engine and put in on the new one so its mpfi instead of the pfi
