I want swap my DPFI in my '89 civic DX to MPFI...What am I going to need...I did a search, but i did not find what I was looking for, mainly a parts list. I was told i could do this swap cheaply, is this true? I eventually have to do this to put a B series motor in this car. What will the Ca, smog people think about the MPFI swap on my D series motor? Also any advice from someone who has done this swap before, would be super helpful.
Thanks

 

Si/EX ECU

Various plugs from MPFI harness all with some wire attached to solder to:
4 Injector plugs
1 Distributor plug
1 Injector resistor box plug

Intake manifold including everthing from the throttle body to the injectors.
Injector resistor box
EX/Si distributor

And for a bonus - Si cam


I would like to know about the Ca smog people opinions too. I don't know if this setup would be legal even though it has the potential of being a "better" system that may be cleaner. From my understanding you can't use an intake manifold that didn't come equiped with the engine.

 

how about the wiring to the ECU does anyone have a diagram or knowledge of how to wire this.
Thanks,

 

I have everything you would need except for the wiring harness. let me know if your interested

 

super interested in this... let me know...

can anyone list the parts number and where to get them, i appreciate your help. thanks.

 

about how much would this conversion run from ( money wise)?
and it doesn't matter if it comes of a CRX or a Hatch right? or am i wrong

 

right

 

I'm buying all of my stuff (except the wiring harness and dizzy) from JohnnyEF for $150 shipped from CA to FL. It really is a cheap mod if you can just find the parts from the right people.

BTW, I need an SI harness if anyone is looking to get rid of one, and a distributor too

Anyone use a Z6 IM instead of a A6 IM??? How did it go for you???

 

ok u do not need any whole wring harness for one u have to run 4 wires to the ecu and swap around 2 pins in the ecu part......as for the z6 mani i used it and it went ok u need the z6 eacv and the throtle body with the tps intact.....if u guys need help with the wiring u can do a few things look in the old sport compact car how to where they show u how to do it....find the post i made a while ago where i posted how to do it look under mpfi directions or something to that extent in archived it may not be there but someone else posted links in other posts im sure.....do an internet search or im me at last resorts and i can help with it a little i dont mind to many ims but sometimes it gets outa hand...good luck guys ull put in a few hours of work and be very happy with the result trust me

 

Here's a site that has the wiring diagrams. http://hybrid2.honda-perf.org/tech/4gdxtozc.html
Also, a while back, Sport Compact Car had an article on how to do the wiring, I don't remember what issue though.
One last thing you might want to try is talking to thumpu77, he seems to know a lot about the MPFI conversion.

OK, well if I don't need the wiring harness then I at least need the dizzy. Anybody got one for cheap??

 

Is this a good deal:
$100 For everything from the manifold up. That'll include the manifold, injectors, fuel rail, throttle body, tps sensor etc. Everything

sounds pretty good to me!

 

the hf dizzy works also so if u cant find a si one get the hf one
100 is a great price make sure u get the dizzy too i had to pay for my ecu but the rest was free when i did my swap 75 for a ecu sucks hard to find si ecus

 

What's a good price to pay for the distributor?? $100??

 

still for sale?
