can you put a z6 head on a b2 and use the stock dpfi

 

nope, not if you want it to actually be a mini-me

 

Upgrade to the MPFI its super easy...the DPFI wont supply enough fuel for the new head anyways

 

thats what i was afraid of, how should i go about with the harness for the plugs and stuff for the z6 intake

 

Goto a junkyard or somewhere to buy the crap...theres old threads that tell you howto do it all...Ive even made a thread like 5 years ago...might not come up anymore...who knows seard MPFI in the EF forum archived not just recent, good luck its simple wiring and all easy when u have the intake manifold off your gonna swap the head may as well do the manifold too!

 

ya true done a mini to a 97 civic havent done 1 to a ef yet, like should i buy the part of the harness for the head and the intake or the whole thing and make a cutom 1 with mine z6 harness for the top obdo for the bottom then a jumper harness for part of the ecu

heres the thread i made damn seven years ago

lol. there's tons of info online of how to do a mpfi swap. i'v got a few sites saved in my favorites for when i do my ls swap.

 

thats what i did on my dx i did put a z6 head on my d15b1 block. still slow as ****.

 

if you didnt wire vtec and do the mpfi, then of course it's going to be slow. It's on the non vtec lobes all the time.....

please tell me you didnt actually expect a horsepower gain my downgrading to a far less aggressive cam profile....

 

I used to run 14.9 with a d15 in a STD 88 HB with a dx 4dr 5 spd tranny
d15,d16y7 head NO VTEC, z6 intake manifold shitty off brand header, 2.5 custom exhaust ebay intake and MPFI so i dont know what you call slow but it was pretty quick not slow 18 sec 1/4 it ran stock

 

we did a mini to my brother zc with his stock intake and we dont have his vtec hooked up and theres a noticeable difference he was pretty close to beeting a 92-95 not sure what year ex without the vtec hooked up on his car

 

wire the vtec, you're running out of cam completely by 6,000 rpm

pretty useless if you ask me.

 

thats easier said then done we dont have a z6 ecu and no jumper harness the cheapest z6 ecu we can find is like 200 but thats ridiculously high

 

i have 2 p28 ecus. i know both the cars they came out of. pm me and i'll give you a good deal on one of them. and no i didnt expect any hp gain from anything except for the mpfi swap. once the mpfi swap is done it will pep up a little.

 

im surprised noone has made a side career out of making full mpfi setups with instructions and selling them.

 

rywire does something close to that but you have to send them both of the harness and so you cant by it straight from them pretty stupid and a rip they want something like 200 for some tape and some cuts

 

So does hasport I believe.

 

id buy it if i didnt have to supply my harness, and for 200 i can figure it out myself

 

i mean sourcing the manifolds and everything. i know there are available wiring sources. but if everytime someone said i wanna do a mpfi, you could just send them to one place/person who sells complete kits they have pieced out.

 

You already know you should go MPFI to get any real gain from this, but... for arguements sake, I bet you could do DPFI with the Z6 head and just run vtec off an RPM activated switch and maybe an adjustable fuel regulator or something to deal with fuel. Fuel would be the big issue IMO.

 

Apekd is working on a ton of harnesses, and Monotech already makes premade MPFI Harnesses.

 

Who are they? And so they can build me an OBD1 B series harness cheaper than the $500 that rywire wants for theirs?

 

Maybe you can talk to chase and see...as a matter of fact ill pm him to come look and see what he can do...
