    ALright dont laugh but ya i want to put a dpfi in a si. I blew the si that was in the car and i sold it with wiring harness. so this is what i got.

    1991 Si conv. (so all the wiring is si)
    D15 DPFI with harness
    SI complete intake manifold

    Just for now i want the DX motor in my car, just to get it going again. I hope someone out there can do some magic. I know if i want to switch it to MPFI i need si dizzy at least. I have the si ecu so thats not a problem. Thanks, any input would be good. LAter

    you could probably find the motor easy. Going backwards in your case might be a little easier, I think you would have to do mostly wiring, keep your same tranny, but finding a d16 for your car probably isn't that hard. If you are going to buy a dpfi d15 and buy the stuff to do the mpfi swap later why not just buy a d16 and put everything in the first time? Save you alot of time and frustration for you to have to rewire everything again. After you buy the new intake for the d15 you might come close to the same price after everything is said and done. Ya you need a new distributer.

    Since the car is already MPFI wouldnt it be easier to just put the SI IM on the DX engine head and be done with it?
