so i put a z6 head on right.. but heres the thing i didnt use the z6 timing belt because i didnt want to take of fmy crank pully n all that crap because i dont have the tools to get that off.. so i used my stock camgear with stock belt (d16y7) this wouldnt be the problem would it? i have no idea why this **** wont start its been sitting around for so long...

You are going to have to do a compression test to get more help here.

timing, check it

slambedcivic

well. youre gonna put your Z6 cam gear back on, and change the timing belt over. the teeth are different and you if im not mistaking changing the cam gear will do nothing as they are both the same. i wouldnt turn your engine over anymore until you get the correct timing belt. if you can change a head over, im sure you can take an impact gun and take the crank pulley bolt out.

What kind of car is it in? The Z6 heads are a lot different than the Y series, you're going to need to give us information. Give us the car year, what distributor you're using, what ECU you're using, and how you've timed the motor.

Cashieboi

its a 96 hatch ek, p28 ecu with conversion harness, z6 distrubtor (atleast i think it is..) i dunno how to tell...the timing seems to be ok iv had a friend check it out too said that it shude be fine.. gears at TDC crank pully looked ok...i keep thinking that the distributor is that problem but i just dont know.. thsi is really frustrating my cars been out for so long just for a simple mini me..

Have you checked for spark and fuel?

As stated before, do a compression test and triple check your timing...

Cashieboi

i checked for spark by taken the last spart plug out (one closest to the timing belt) and put it by the block trien to start it up.. is that right way to do it? i didnt see spark btw.. and i dont hear my fuel pump comming on ... i tried spraying brake cleaner in the intake mani and startin it up quick to see if fuel was the prob.. nope...no fuel.. could be my dizzy then right?... if it is is it possible to use a y8 dizzy on a z6 head... cause if i can use that then i wouldnt have to rewire my dizzy again so the plugs match up..

BauleyCivic

You would have to re-drill the Y8 dizzy to fit a Z6 head...I believe it can be done. My guess is the issue is your distributor. I have never recommended doing a Z6 in an OBD2 car because Z6's are timed for 16 degrees while Y8's are timed for 12, and there is no OBD2 distributor that fits a Z6 head.

Cashieboi

so i shude prolly just get my dizzy tested sumwhere? where can i get it tested at?

Cashieboi

what are u talkin about thats timed 16 degrees n all that?

Base timing is 16 degrees BTDC (before top dead center) on a D16Z6, and is 12 degrees BTDC on a Y8.

Did you do any research before you did this?

Can't ignition timing be way off and the car still start? Won't it just affect performance?

I'm trying to remember, but I think mine was off by at least 8 degrees when I first started my mini-me, and I didn't have any problems.

I'm pretty sure that you need to use a different belt then the Y7 one. I may be wrong. If the belt is jumping teeth then it wont start and could damage your engine. If i were you i'd check the FAQ.

There is a write up on the mini me and what is possible with each different combination of block and cylinder head. Also check over that and see if you may have missed anything. You really need to go back and try to start over.

Cashieboi

iv read writups that said they reused the y7 belt with the mini me swap so im guessin that it will work... the gear seems to be the same on the y7 and z6 so it shude work shudent it? anyone kno for shure thats done it before maybe?? iv heard from many sources that you can reuse the cam gear from the y7 and the belt and its fine... anyone?

s_vares

Ive been running the same setup for 2 years now. mine been good.
I used the y7 belt workd fine but you will need a cam gear to get the thing running right and a y8 Dissy. Run your cam gear at 4.5de adv. Also set your timing at 16 deg. as the marks an your crank are for 12. Use judgment as the marks on your crank ar 10-12-14,so run it another 2 advance or so.
i think your belt is off a notch as to why it wont start. Give me more info if I can be of any more help.

so you used the y7 belt and cam gear with a z6 head? you can use a y8 dizzy on a z6 head or did u have a y8 head? cause if i could use a y8 on a z6 head that would save me so much trouble of rewiring the z6 to fit my plug. So set my crank to 16 instead? and the gear turning which way? also wat does the main relay for my car look like (96 ek) casue i was also going to check that but im not shure where its at

The main relay is grey box by the glove box.
I used a Y8 belt and a AEM adj. Cam gear for a z6 set at 4.5 deg adv.
The Y8 Dizzy will work, or a z6 body with the y7 guts.
Set ignition timing to 16 BTDC

Cashieboi

ok so u basically used a z6 belt not a y7 one? do i need to advance timing with the y7 or did you just advance for the y8? im gettin confused now.... and how positive are you that you can use a y8 dizzy on a z6 head? can you use obd 2 dizzys on a obd1 head?

bsixteen

read what he said. he used a Y8 belt with an adjustable cam gear.

he also said the Y8 distributor will work.

Cashieboi

well yea he said that he used a y8 belt but why dont u read wat he said before.. he also said the he used the y7 belt.. now those are 2 diff belts with 1 tooth difference... so i need to kno if the y8 belt needed advancement or the y7 belt with the z6 head needed advancement.. need to be really specific here we are talking about timing this isnt sumthin i wanna start advancing my timing on and get a bent valve listening to sumone on hondatech
