like said below im working on a mpfi conversion first of all ive seen a whole bunch of sites on how to do it, some are easy some are hard,some work some just guess how to do it. could someone give me a site that shows the easiest way to go about it. im pretty sure i got everything i need.the only thing i dont quite understand is why u need to swap dizzies. my friend GAVE me one that he says came off of a mpfi engine but its looks identical tomine so how canu tell the differance. i also like the idea of web site that some one has used and knows it works

The easiest way is to sell your car and get an Si. If you still want to swap yours, search.

easy? send your harness to Rywire and have them take care of it :TU:
yeah but if your like me and only have one harness your gonna have to pay like 300 bucks for this to happen cause a DX harness they charge $80 and a Si one is like 110 plus the 160 they charge to do it PLUS the shipping costs trust me I already looked into and I know your gonna say go to junkyard and find one cheaper but I rule that as an unknown cost especially if they don't have a si car readilly available for you to rip the harness and all the associated bullshit that goes along with that type of thing. I see Rywire as a gauranteed thing. It just costs you an arm a leg and a penis.

you don't have to send your harness anywhere. i did a conversion using www. j-k-tuning.com you do need a p28 ecu ,and they have a combo with conversion harness,and ecu chipped with crome or uberdata. all you have to do is plug their harness into your stock plug ,and plug the other end into your p28 ecu. it also comes with instructions for the wiring to the dizzy ,and fuel injectors. stock dx non v-tec, z6 motor v-tec needs different dizzy to wire v-tec. plus mpfi has two additional fuel injectors which also ties into the v-tec. that is why additional dizzy is required any questions pm me already done this swap

yeah this is the best mpfi writeup ever.

i've done the swap and it isn't that difficult, if you want to do it yourself, do it. Just read up and understand what needs to be done.

Realize you are modifying the stock dpfi harness by splicing in parts from the mpfi harness. Why are you doing this? Because the shock tower plugs are different on the mpfi harness, nullifying it from plugging right in.
