Help, I'm scared
 

Hey

Alright, so very soon I will be attempting a mini-me swap for the very first time. I'm going to be using a d16z6 head on a d15b2 block. Now here's the part I'm scared about, I also have the d16z6 intake manifold which I will be using as well.

I've searched, and looked, and am still pretty confused, because everything I look at pertains to a z6 head on an a6 block, which I don't have.

So my question is, if I'm swapping both the head and the intake manifold, along with getting the P28 ECU, what sort of wiring am I looking to do? I'm really confused on whether I need to get a Z6 harness, whether I need to switch from DPFI to MPFI and what I have to do in regards to switching from OBD0 to OBD1?

I've looked at the write-ups for going to OBD1, and they're all based on the A6 MPFI setup, so would it just be best for me to rewire my DX ECU to MPFI, and then convert that to OBD1? I'd really rather not have to fab up my own harness if at all possible, it just seems like I'm missing something here.

So thanks to anyone that can help me out, like I said I've searched and looked and even with the stuff I've found I'm stuck, so if someone has done this before and could give me a hand with it, or point me in the right direction, that'd be awesome. Thanks in advance.

from my experience you have to go to MPFI then do the OBD0-OBDI swap

Re:Help, I'm scared
 

Ouch, sounds like alot of wiring is ahead of you man. Like mentioned above, you need to do the basic DPFI-MPFI swap first, then convert to obd1. You can just swap in another harness and call it a day, if it was that simple that would be great ;)

Your better off just sticking with obd0, the dpfi-mpfi swap itself is pretty easy. Also you can skip the injector resistor wiring portion of the swap since you will be using saturated injectors from obd1.

If I stay OBD0, I'll need some way to activate Vtec still, right? Either way I need a new ECU :-\ since I'm running DPFI right now. I'm ok with wiring, I've got the pin-outs and everything, and I've been soldering for a while now, it's just gonna take time to do it, and I was wondering what all I needed to do. Thanks!

do the dpfi to mpfi, then just run a rpm switch for vtec

Re:Help, I'm scared
 

I was doing that exact same thing. I got pissed off and junked the whole car when I couldn't get it figured out. SOrry if it discourages you. Good luck

Re:Help, I'm scared
 

why not do the DPFI to MPFI and then just get a VAFC and use that to control vtec...or am i missing something? im juts taking a stab at it...cause i've never had a vtec motor...hope i have helped!

Re:Help, I'm scared
 

if u stay obd0 get a pg7 ecu otherwise you'll get fuel cut @ 7k.

Re:Help, I'm scared
 

doing it right means runing the p28, or at least the maps from the p28 on a chipped OBDI ecu.
