I have come to the conclusion, that i need to come to a conclusion. As of now i have NO car. With the money I have, I can either get a ZC or a Mini Me setup. Today, I actually took a look at a friend's D16z6 head (complete, milled, gaskets, etc..) he wants $150 for everything. On the other hand I can buy a ZC long block for $250. After talking with some sources ive come up with some pros and cons for each..
DOHC ZC: Pros: DOHC, under 40,000 miles, bolts right in, more power?; Cons: Lack of Parts, JDM = not smog legal, costs more.
Mini-Me: Pros: VTEC!!, High Compression ratio, more power?, lots o' parts, VTEC!!, cheaper; Cons: 180,000 miles on the block, complicated, ive heard that the pistons will hit the valves, higher risk of failure.

Im gonna need some opinions because i need a car ASAP, and i need power. Also, ive gotten quotes as high as $500, just to put on the Vtec head. $600 just to bolt on the ZC! what should i do?

u are right abou thte risk of failure, but my friend is running around with one, and i know another guy runnign with one, i helped put the mini me swap together, valves dont hit if u put the timing belt on . ZC is JDM motor less parts available, more pain in the ***, aftermarket might be hard to find.

if you dont go with the mini-me, tell your friend i'm interested in the head for that price.

CRX_VTEC

Go with the mini-me set up. You have more potential to work with. As for the block being high on milage.... just break down th block and add new bearings and belts and pumps. It'll be as good as new.

Go with the mini-me but if you can just get the a 92-95 ex/si or 96-00 ex long block. It's not that complicated. If you have a si all you have to do is add vtec wire you don't have to add the vtec oil wire. If it's not a si then you'll have to convert it to multi point. I have a 89 civic std with a 95 D16Z6 with intake, headers, and vtec controller. I've had it for 2 years. I love it. I run high 14s (best time 14.7) with heavy *** 16s. When it was 1.5 d15 4 speed I ran 16 flat at sac raceway. The top end is crazy for a d16. I've beaten 2 zc powered ef's. I think it's easier to get power out of the mini me. With the d16a block you'll have higher compression then a d16z6. You'll probably be pushing at least 135 hp compared to 130 of the zc. It's about the same torque wise, the zc is a tad better. I might be bias, so what I love my car. I've beaten ef's with b16's, eg's with LS motors, a turbo ex, stock tsi's, any stock all motor car (gsr, prelude vtec)with bolt ons, and the best thing about the mini-me is that you could say that "it's just a D16" and surprise them because it's quick all motor. I'm sure you could find a d16 block for much less then a zc. I've seen a crx with a d16z6 run 13.9 with intake, headers, exhaust and slicks before. Just email me if you have any questions.

asnx6pac, do u have the whole d16z6 motor or a mini-me swap? 14.7 is very impressive, did u lighten the body at all?

brad.

14.7, thats pretty impressive for a SOHC vtec engine. Just curious, did you guys have to do anything to the block? how fast is the minime setup? anyone have instructions how to do it?

91ED7Si

16flat on a d15 4speed?
you running juice on those times?

asnx6pac

It's the whole motor (stock internals). I don't have the front bumper support i took out the back seats, the spare, all the sound proofing stuff, headliner and everything between the interior panels but i put the panels back in. Stock block....no internals....just intake, headers, vtec controller, act heavy duty pressure plate (stock clutch). Stock pea shooter exhaust piping.

asnx6pac

the 16 flat on the d15 4 speed was completely gutted almost everything gone except for the dash and driver seat. driver skill haha just kidding...

i will be posting my 1/4 mile time sat night
i'm going to the track sat

max

dude, i cant wait to see some real times for your car. u basically have the same setup as me, just in a hatch. i just need to get my v-sfc or v-afc and then i can go to the track myself. btw, weigh your car at a highway weight station. it only costs like $7, but it's something very important to know.

[626] SiRJKwIcK89Ef

Well, looks like im conivinced that Mini-me is the way to go. Tomorrow im going to buy my friend's head (milled, throttle body, intake manifold, all gaskets, but no ecu) for a mere $150!! I think im getting a good deal. Taking off the head has proved to be a pain in the ****, but its coming off. Now comes the hard part, figuring out how to install and working properly. Any help or suggestions?? I might just a pay a friend who does it often to just do it for me, he was asking around $350 for the install, is it a good deal?

max

$150 for Z6 head is great deal, expecially if it has work done on it already and u have the intake manifold. i paid $225 for just the head. anyway, do it all yourself. there is nothing to it, and why do u say that taking the head off was a pain? go by the manual and it'll be easy. get a timinig belt for a 92-95 civic. dont forget to take the oil jet out of your block before u put the new head on. take a screw and put it in the little hole, then pull out by the head. u'll have to cut/drill the distributor mounts. i dunno what people are bitching about tho, mine holds just fine on only 1 bolt that is going through a cut mount u'll need the torque specs for the Z6 head tho, which i have and can give u if u dont. basically there is nothing to it, disconect a bunch of wires, take old head off, put new one on, connect the wires back

Thanks for the info Max, how long did it take you to do the whole setup? are there any other expenses that you had? It was just a pain to take off the head because some bolts were hard to get to. I have a JG 301 cam in my stock engine, will this be able to go into the Z6 head? I also have a Prospeed ECU program, will this work fine with MiniMe setup? I talked to someone who said the Pistons may hit the Valves, any truth to that? By the way, Max, it would really help if you can give me the torque specs for the d16z6 head and anything else i might need to know for the install, thanks.

W0oT

you will also need a 92-94 ex/si FPR, 92-94 ex/si head gasket. and use your upper radiator hose coolant elbow from your non vtec head that way you don't have to find a new rad hose.... hrmm anything else i'm forgetting. ohh if you want to get the head gasket material off easier go to napa and buy a gasket removing disk it's like 4-7$ and makes life madd easy w/ a drill or die grinder of some type. ohh yeah you'll need a vtec controller. i don't see why your ecu wouldn't still work. your starting your swap w/ a 1.6 non vtec block right?how is it set up??? race, drage, fuel curve ect??? it might be a really good thing might not. don't forget the vtec head needs more fuel. ummm.... what else. i used a curved set of pliers w/ a very small head to yank my oil squirter out. don't worry if you damage the squirter you won't need it just try not to scratch up your deck.

here's my engine compartment

TypeR0207

No doubt! With 117,00 miles and a totally stock car that burns a little oil, I ran a best of 18.9@70 in my STD turd!!

[626] SiRJKwIcK89Ef

Yeah ive heard that i might need that 92-95 FPR to handle the extra fuel. My prospeed ecu adjusts the fuel curve so more fuel is added, the rev limiter is at 9500, but i never took it that high. Will my JG 301 cam work with the Z6 head? its off my old non vtec head. Hey Nismo, when are you gonna update your page and show the complete mini-me swap? I need some instructions.

sicivic

Sorry to say, your JG 301 cam willn't fit in the Z6 head. The Z6 head has a vtec cam in it which is different that the non-vtec cam. Even though your computer is upgraded, I would still get a 92-95 FPR or buy an aftermarket one which is probably what I'm going to do. I'm in the process of doing a mini-me swap as well.
As a matter of fact, my old head is already off the block and I'm about to put the Z6 head on. Good Luck

DOHC DX:

JDM motors r not legal in CA...AT ALL...and the dood lives in CA

[626] SiRJKwIcK89Ef

Yeah, here in Cali, JDM motors are hard to get smogged. My brother is having a hard time figuring out how he is gonna get is JDM B16a smogged, and a ZC will be just as hard. MiniMe should be OK, assuming that it runs clean. In fact in going to pick up the Z6 head in a maybe a few min. Im still in the taking off my old head, almost done. I think i have all the necessary parts for the install, do i NEED a 92-95 FPR and a Vtec actuator switch? How exactly do i need to modify the distributor?

[626] SiRJKwIcK89Ef

I dont know if any you guys had problems with this.. but im having some trouble taking off the head. Im pretty new to doing internals by myself, but i cant seem to take the bolt on the bottom on my intake manifold out, its hard to get to. Taking off my distributor, i broke the 12mm socket and stripped the bolt a little. I guess because the engine is so old, everything is pretty hard to take off. I need VTEC!

brad.

ARGHHH!!!! i need SMOG!!!!!

go outside and breathe in
