.. i jus bought a 89 civic hatch and its dpfi.. i have around 500 to blow on it and i i dont know wether to try a mpfi conversion(seems kinda complicated but im ok with wiring) or to swap a y8/z6 head..
if i did use the z6/y8 head..what ecu would i have to use?
thnks in advance..

 

plzzzzzz anyone..jus a lttle help

 

if i was u ill do the mpfi and at the same time do the mini me in my opinion i would use the y8 head beacuse i can use the same si dizzy with out modifing the head.

 

here is a good link where u find alot of help just scrol down

i just finished the mpfi swap bro, it will make you cream ur pants. it beats the hell outta my buddies 2000 civic now.... send a pm to a guy called monotech on here and get the conversion harness. it plugs right in and looks oem. if you want check my build thread for pictures and a video. it is called very slooooow build up and dont be afraid to leave a comment. i think i spent 250 bucks on it. you need harness(optional but much much easier) intake manifold from si, ecu from si(i used pg7 from integra to get 7200 rpms) and an si/hf distributor. after you finish hold onto your ***** man. good luck

by the way with a y8 head, its vtec and u will need to hook the vtec up and get the y8/z6 dizzy because its vtec, and a vtec ecu.

 

using the y8 vtec head will allow u t use the ef si dizzy and for the computer u can still use the same ecu but u will need a way to activate vtec there is differents ways to do so from real cheap (like 2 dollars swich ), a shift lite , rpm module i think that what it is , vafc, chiping ur ecu etc

 

if its gonna be done, why not do it right. if he has 500 bucks, have the harness made with the vtec hooked into it so it is all good. sounds like the right way to me....

 

PM <U>monotech</U>

 

thnks.....ima get my cash if see if i can really do this
1 more Q, if i buy the harness i dont have to do any wiring from the ecu(all that c1 to b12 ****)
thnks all u guys

 

you will still have to unpin two wires and plug in four. montech runns the wire right to your ecu for you all you have to do is switch them up. good luck
