Mini Me swap question..Which head
 

Alright i'm looking for some info for a buddy of mine.

He has a 00 civic lx..d16y7..he's looking to do a mini me swap. I have found him 2 dif. heads. the Z6 head (which is the 92-95 head correct?) or the y8 head (obd-2 head correct?)

which one of these would be better to use on the y7 block? what would the compression be after each head, and which one would be easier to use with stock wiriing.. I'm assuming the y8 because its a obd-2 head..


ps. he's going to use a p2p for now for mangement

Re: Mini Me swap question..Which head
 

also does the y7 have the oil jet that is supposed to be removed? i've heard yes and no..so any expierenced help would be great

Re: Mini Me swap question..Which head
 

yes the y7 does have a oil jet to take out for mini me swap..the y7 block with the z6 head will put out 13.6:1 comp ratio! and with the y8 head its 13.2:1 comp ratio
and me personaly I would use the z6 head I am sending to you..I would choose z6 over y8 anyday...but thats just what I think..find out which head has best specs and such and use that one..

Re: Mini Me swap question..Which head
 

wow, yours way off on those compression ratios. y7/y8 mini-me doesnt change the compression, both heads have the same cc volume, y7/z6 mini me will lower the compression a tad because the cc volum of the z6 head is larger than the y7.

Re: Mini Me swap question..Which head
 

check it out on the d-series compression calculator..

http://www.knology.net/~jediklc/D.htm and tell me what you come up with....

Re: Mini Me swap question..Which head
 

either way its gonna be better with the z6 head..

Re: Mini Me swap question..Which head
 

i just did, and exactly what i said, 9.5:1 w/ y8 head (same as stock y7) and 9.2:1 w/ z6 head. dont know where you got 13:1 from????/

Re: Mini Me swap question..Which head
 

I guess I was doing something wrong :S lol...thanks for correcting me...

Re: Mini Me swap question..Which head
 

alright well since i am getting the z6 head, is it possible to get a thinner headgasket to raise compression back up to around the stock, or even higher..i thought doing a mini me swap raised compression. kind of disappointed that it doesn't..

also greddy07, from what i've heard the y8 head flows better, and since it keeps the same compression ratio, i think its a little bit better than the z6

Re: Mini Me swap question..Which head
 

if you want to raise compression i assume you dont plan on boosting so what are you doing on HMT?? this question will get you alot of answers on HT, just gotta hope those idiots are right.

Re: Mini Me swap question..Which head
 

I'm here because i do have a HMT setup. but its on my cavy not, a honda. Honda tech is gay, and i don't own a honda so why bother going over there to ask. when this is mostly a honda site also and i should be able to get my question answered here. Also i don't believe in the "lower compression is better for boost" O0..but hte car isn't going to be boosted anyways, its his DD..he just wants it to be a little peppier ;)

Re: Mini Me swap question..Which head
 

in that case tell him to "search" :y

Re: Mini Me swap question..Which head
 

You can get a thinner gasket, we offer them from Cometic down to .027". You can plug that value into the same CR calculator mentioned earlier, to see what your ratios will be with the thinner gasket.

On our A6 MiniMe project, we chose the Y8 head, because it allowed us to just plug in the OBD0 distributor without converting or repinning anything. Not sure about the combination you have, but it may be something you'll want to check out before commiting to a particular head type.

Re: Mini Me swap question..Which head
 

that was another concern of mine was the dizzy.. allthough i'm searching for info on that. maybe someone can answer it before i find it myself. we are using a stock y7 bottom end, with a z6 head. and p2p for controll as of right now, but that can change if need be. what can i do for distro?

Re: Mini Me swap question..Which head
 

all 88-00 D series dizzy have the same bolt pattern except 92-95 vtec dizzys. td42u i think. the rest all bolt up and are interchangeable. so if you are using a z6 head use a z6/z1 dizzy and repin, or hack the mounts on any other dizzy to work.

Re: Mini Me swap question..Which head
 

You mention about the Oil Jet on the block of the Y7, where is it? Is that why sometimes my oil drip stick reads that I'm low on oil but when I topped it off and let the motor sit about 3-4 hrs and it reads full but the next morning I check it again and its way over filled? I have the same setup in my 93 DX coupe and I test the compression on each cylinder and got 199 for all of them. It does feel a little better then a regular D16Y8 or the Z6. But now that I'm going to put my stage 2 clutck kit in it and maybe feed a little dose of the SPECIAL stuff from the BLUE Bottle I can hit low 14's w/ street slicks.

Re: Mini Me swap question..Which head
 

what kinda compression would a sohc zc and a y8 head get? z6 head? average horespower with full bolt ons?

Re: Mini Me swap question..Which head
 

same as an A6 minime, or very close to it. assuming you are talking about the obd0 sohc zc
