I've just picked up a clean JDM DX and i'm looking into swapping my H22 motor into it. I'm confident about everything except the wiring.

Just converting to multi point injection confuses the hell out of me and wiring in the H22 makes it worse.

Would it be easier to convert to MPFI first for the D13 and then start a fresh and wire in the H22 or do it all at the same time?

 

what car do you have? if its an eg i don't see why you have to convert to mpfi...

 

Yeah i have an EG DX.

I kind of understand wiring up a H22 into a chassis that was already running MPFI. And i kind of understand doing an DPFI to MPFI conversion. But i'm unsure what the differences are when putting a H22 into a DPFI chassis?

 

If you have a EG DX then it is already MPFI

 

I'm pretty sure its DPFI.

Airbox ontop of IM, no injectors near head.

Its a D13b engine, and a Jap import if that makes a difference?

 

You have a EG 3 D13B carburated 85HP@6300 SOHC 1.3l, correct?

 

Ye that sounds about right.

This is all new to me, i've never messed with anything other then multi point.

 

carburaters are completely different from dpfi. pick up a complete wiring harness from an mpfi eg

 

Ah ok, thats not what i wanted to hear lol.

Do you mean a complete interior or engine harness?

If you know of a link for the conversion that would be great. I can't find anything in the archives.

Will the stock fuel lines need changing out? I know the flexi line needs to be changed but not sure on the hard lines.

 

yea its not looking good for u. Your prolly going to need a whole engine harness and like you said fuel lines. The hard lines should stay the same , altho I could be wrong. Goodluck

post up a picture of your engine bay...if the fuel filter is the same as every other eg then all you need is a fuel lin from the filter to the rail. for the harness...just from the ecu to the motor...its a 2 piece harness, it goes from the ecu up through the firewall and along the framerail, 3 connectors next to the strut, and then that section of the harness goes to the motor

 

I've just been down and tryed to take a pic but its pitch black out side, even under a street lamp i cant get a good pic. I can get one tomorrow though.

I had a quick look but i couldnt see the filter where i thought it should be. On the left hand side of the engine bay on the firewall?

 

No luck with photo today. Hopefully will get one tomorrow on my lunch break.

The H22 i will be using is coming out of my EG ESI. Since the engine harness has already been modified should it plug straight into the DX wiring?

 

take the wiring harness from that car that runs from the ecu to the motor from that car an put it in the new car. just swap whatever is needed from that car to the new car

 

Nice one! Things are looking good for the swap.

Now just need to work out what parts of the fuel system need to be changed. Hopefully it is just the flexi line going from the fuel filter to rail.
