this is the only thing i need to turn a dpfi car to mpfi with a complete motor swap right?

 

u need the manifolds and injectors fuel rails etc. ///m

 

you also need injector clips (88-91 preferably, but 92+ will work if you exactoknife the tang out of the 88-91 injector female receivers.)

..and a distributor from d16a6 as well as the large round 8 pin distributor plug lead on the harness end. the dx distributor uses 2 square connectors, Si uses a round one with 2 more coil wires.

generally, you start with a dx engine harness, cut off the parts from an Si harness and add to the dx.

What???

 

Ya man, you have to do a mpfi swap on the dx harness. Check my sig.

i just recognized that the plug you snipped in the photo, the male is still in it. that plug fits the distributor. color code will be wrong, but if you cant find one, that will work.

 

im not going to do mpfi on my current motor. im going to get a b16 complete swap. and thats going to have a complete harness. so i was asking is the resistor thing the only thing i need?

Maybe a fuel line. I don't know if it comes with the complete swap.

 

its sounds as if you anticipate the b16 harness to plug into your car as is. this would mean its an 88-91 jdm ef harness i assume?

in that case, it would already have a resistor box, so im confused at this point.

 

Even if the B16 swap you are getting comes with a complete harness, it is not going to plug into your cars harness. It will help because you can use the clips that you will need to upgrade the stock DX harness, but I hope you are confident with your wiring skills, and that you study up on this very well before you decide to jump right in and start cutting up your factory harness. If your car doesn't have the resistor box in it already than I am guessing that you are going from dual point injection to multiport, and if thats the case than you have to use your stock harness and just upgrade it. Trying to wire the stock JDM B16 harness into your car would be a big nightmare.

 

so i use my stock harness but get the clips and what ever from the b16 harness? and hook and the resistor thing and er tang else.

 

youre pretty brave for someone that doesnt seem to have a clue about this. im amazed you havent been thoroughly flamed by now but im not the type of guy to put people down just for the hell of it. still, no one even told you to search and this topic is one dead horse. you got off easy.

do yourself a favor and read this about 5 times. its pretty accurate but a few additional wiring schematics wouldnt hurt. write down the color of the wires going to your eacv and iat BEFORE cutting **** up. they are the same plug and often get mixed accidentally. if you dont have patience, soldering experience, a good deal of 22 awg i think, heatshrink and a high quality soldering iron, i would advise you to buy a premade harness. electrical gremlins are the hardest to troubleshoot because they are usually intermittent.

 

ha haha, patience and soldering skills are pretty good. and i got everything needed.
