My D15B2 on my '91 Hatch **** itself today. The good news is that I can get another motor from a '90 EX at the local junkyard. It's got everything I need for a complete D16A6 swap. I've read some older posts and still not entirely clear here. If I pulled everything: Engine, harness, dizzy, resistor box, manifold/tb, injectors, fuel rail and ECU would I still need to do a MPFI conversion like I've read in older posts or is it simply a plug n play affair. My EF is an auto, and so is the one at the yard. Not sure if that makes any difference. I'm just looking to get my car back on the road as it's my only vehicle. I figured I could try to give my EF some more power even if it isn't much lol. Any help would be appreciated.

 

you would need to use the engine wiring harness that is in your hatch and do the DPFI to MPFI wiring changes - the MPFI engine harness will not plug into the DPFI chassis harness, and the DPFI chassis harness does not have all of the necessary wires from the ECU to run the MPFI
