hey no exact swap list found... just dpfi-mpfi lists found. i want to keep this as simple as possible. what is everything i need? i have 90 hatch with d15b2. i alreayd have PM6 ecu. can i jsut get the wiring hirness and complete motor and drop it in?

 

You were not very clear on what motor your are swapping...I'm assuming an Si motor?

 

for any kind of swap using the MPFI engine in your DPFI car you need to use your DX engine harness and convert it to MPFI - wiring harnesses are not interchangeable

 

im sorry, posted really early this morning. ok. i have bone stock 1990 CX (STD) with d15b2 and dx tranny. im going to keep my transmission, its in perfect shape. all i want to do is throw in a d16a6 to replace my high mileage b2. i have PM6 ecu. so i want to know, all i need is the complete motor and si wire harness to swap right?

 

no. you need the si distributor, intake manifold, throttle body, accelerator cable, injector resistor box, both the si harness and your original harness. you have to cut and splice together the to harness' to make one. you have to switch i think 4 wires right at the ecu. i just did the same swap and it was more to it than i thought.i suggest sending your harness' to rywire. or if you have a local performance shop maby they can do the swap. im guessing your car is 5 speed already. if it aint though you need the pedals and clutch cable from a 5 speed. im guessing the dx tranny your talkin about is 5 speed though. good choice of tranny in my opinion. i tossed my si tranny for the dx tranny. i could only run up to 20 in first gear with the si but with the dx i shift around 32. also if you want a little more power once you get it right you can swap the ecu for an integra obd0 ls computer. now i redline at like 7000 instead of 6500.

 

As far as the harness, I'd go with...

Once you install that harness, send him your old one and he refunds you $25. He also includes the resistor.
