mini-me options

alright, so i got an extra D-block now with about 110K miles sitting in my garage which i want to use in my Hatchback project (which i shall be acquiring soon 
).
anyways, i was at the junkyard today, and there was a Z6 engine and a Y8 engine. the Z6 had about 230K miles on it, the Y8 im not sure. boh of them were missing their VTEC solenoids though :x
i was thinking about pulling the head from one... but im not sure which one i should get haha.
im guessing Z6, because its OBD-1 and that seems like it would be easier to do. i dont really know though, im not sure whats really involved in the Mini-me process or anything so yeah.
im hoping those that have done this, can point me in the right direction.
also both cars' ECUs were gone, as well as dizzies. all i could pull the is the engine wire harness, if need be.
i didnt have any tools with me really, so i couldnt take off the VC to see what the parts looked like underneath, but i guess that would be a step eh? haha. ANYWAYS.
chime in!!

Thats my plan: Z6 head, Y8 IM, B18B TB, Z6 dizzy(not the A6 thats on it now)
Don't mind the paint on the VC, not my doing. And that TB fits, I just didn't have it on all the way before I snapped the pic.
I got the z6 head put on mine and got it running without the vtec (for now). I'm waiting to pick up a valve spring compressor. The valve stem seals on my head are leaking. It would probably be ok to drive it but I've got a loner car so I'm going to wait till I get it fixed.
I guess the y8 manifold is a heavy breather. There is one sensor you have to custom mount to make it work though.
From all the research I've done I've decided to go with the obd0 to obd1 swap. Stock p28 ecu.
For now it's running obd0 with a modded obd0 distributor.
I did a little research on adding a b18 throttle body (because I just happen to have one). I pretty much got the feedback that it's not going to really make any difference unless go turbo or something of the sorts.
I found one of the y8 manifolds locally. I think I'll end up picking it up sooner or later. just don't think I'd wanna hassle with it while I was working the rest of the swap. But word on the streets is that they probably are as good of an upgrade as most aftermarket units.
Y8 manifolds breathe alot better and are what the skunk2 guys based there d-series manifold off of.
Sensors are sensors, obd2 might have more or less(???) but you only need to use the sensors that your ECU needs, thats why obd0-obd1 swaps are easy cause you can use the same wiring harness to the sensors on the obd1 motor with a few added wires for vtec, 4 wire O2, knock sensor.
last question, is the Y8 intake manifold much different then a Non-VTEC head of the same year?
cheers
Not really sure what you mean, but I'm guessing that you are asking if the IM's are the same between VTEC and non-VTEC. No idea
As for the head, for an N/A application take the Y8 head as it has a slightly smaller combustion chamber than the Z6 for higher compression as well as quench pads that are better for all motor builds. In reality either head would work fine, whether N/A or boosted, you probably wouldn't notice a real difference if you built two mini-me setups to compare the heads. Just remember the Y8 runs different timing.
Also Skunk2/Blox and the other Chinese D-series intake manifolds floating around out there are garbage and a waste of money. If you put an S2 manifold on a flow bench against a Z6 manifold, you aren't going to see an improvement. Just a word of advice to everyone, don't waste hundreds of dollars on parts that don't perform.
A ported Z6 intake manifold with big bore throttle body is going to run circles around a Skunk2 mani.
Here it's kind of explained. WARNING though, first post contains a few pictures of women in revealing undergarments... NSFW probably.

This EF std. hatch if memory serves me right has less than $3k invested including the purchase price of the car. D16Z6 with ported Z6 intake manifold, big bore throttle body and plenum spacer from http://polarbeartuning.com/, car runs 10.54 @ 132mph.

Chris Maletsky is the man to go to for your D-Series port work needs, the entire RealHomemadeturbo website will vouch for him.
Good luck with the build!
anyways. cool. grand total was $80.14 and i got a free lip as well
that includes COMPLETE intake manifold..injcetors, fuel rail, etc for $20
complete head for $50 + $5 core.
add tax and you got $80.14 hehe
this head was missing the VTEC solenoid.
anybody got a spare Z6 solenoid sitting around they wouldnt mind donating to a good cause? LOL.
B18A1 Throttle body. bolt holes line up, but the surface of the TB and IM dont, dunno if this will be a problem haha..
wagon....................4ever.................
its going to be QUITE a while before i get anywhere with this. as in, Wagon will get its swap first haha.
D16A6 short block - i have this under my bonnet
Z6 head - i got this from a friend
D16A1 - dome piston but i have to buy this (is this a good idea?)
Z6 or y8 head gasket - which is better for future turbo?
b16 throttle body - future upgrade
p28 ecu - i still have to get one
any thoughts here my wagon bretheren. i am in the process of collecting the necessary hardware and knowledge for this awaited project.
thanks

what performance do you expect?
cause we aint talking...
and i speak for myself...
If your building for turbo, from what I've read I'd prob use a vitara piston, and the z6 gasket. That will give you the lower CR you want for boosting.

that should help you in your build.
