dual point to mpfi

got a 1990 civic hatch dx with a bad motor so im putting in the 1.6 form the si.i was told i can use the same manifold i have on the 1.5 and stick with the dual point but i want to know if i do that will that hinder the engines performance and if i were to convert what would be involved in making the switch

Yes it will hinder the performance, things involved are wiring the extra injectors and resistor box to the ecu and some other minor wiring, use the search feature..the mpfi swap has been done hundreds of times and writeups are everywhere..

I actually make custom wiring harnesses that are completely plug and play. If you need one, please PM me for more info. There is alot of work involved in converting your car to mpfi, and is quite in depth in understanding for someone who has never done it before. I have sold hundred's of harnesses, so you can be assured that my harnesses work every time, the first time. Period.
Of course, if you need guidance in doing all the wiring yourself, I will also help you as well, just let me know.

man what doesent bambam do? i just did this mpfi swap but havent had the chance to see if it all worked out yet. wish me luck but for you dpfi manifold on the si motor you will need to put your old distributor off the dx to the si they have different plugs and finctions.

Lol....well, wiring is my main forte....
I've been building these harnesses for awhile now. I do all the harnesses and wiring for the shop I work at called 411 performance in norwich, Ct.
I also do all of the rebuilds and builds there too.
I don't waste my time on installs anymore...it's just not fun anymore. When you swap 10 b16/b18's in hondas a week...it does start to bore you...lol.

But yah, my site is finally up. Online ordering is not available yet. But if you do see something you need, hit me up. Also, if you need something that isn't posted on the site yet like K20 swap harnesses, let me know. I can do anything! I also have the lowest prices on conversion harnesses! I'm also planning on running a special next month for automotiveforums.com 4th gen forum users, so stay tuned for that.

Is it possible to use and ex/si engine wire harness on a dx chassis

no sir you can not.

nope.
The conversion MUST be done. Like i stated, I make completely PLUG N PLAY harnesses for what you need, that's if you can't do the wiring yourself.
The price for that harness is $89 shipped.
That's nearly HALF the price of the top competitor.
You send me the cores, turn around time is 2 days, then it's shipped back to you. So let's say you overnight your harness to me (with si harness), You can be installing it into your car 2 days later, if you want to pay for that shipping option.
All harnesses include full directions, and everything you need. Every connector on the harness also comes clearly labeled so there isn't any confusion in plugging it in.
great shit. :thumbsup:

trust me and bam on this. his price is i dont even know words for it. if i would have come across you while in the dp to mp confusion. i definetly would have done it. that price is great. hey if mine dont turn out to good im gonna hit you up for that deal. trust me check prices on hasport.com and rywire.com guarerteed the lowest price and much more. and just to clear things up. you can only do this 3 ways. convert it over yourself/shop. pay for a plug play harness. or by the full mpfi wiring out of another crx/civic. i forgot which you had. so take your pick and if anyone else knows a way let us know

oh and bambam, what about a sub-wiring harness for vtec and the knock sensor. how much would that run me. i could do the pin swaping at the ecu if that saves some time and some money on my part. thanks

$39 shipped. That comes with priority mail as well.
There is another option as well that I offer. You can send me your stock harness, and i can send it back to you with the vtec (and mpfi if you haven't already done that) wiring integrated into it as if it were a stock harness. I completely strip your harness. Add the vtec plugs, and retape it and loom it back to a stock look. This option is $69 shipped.

let me know. all of my prices are available on my site as well in the products section at http://hybrid-creations.com/products.htm
