ill try no tips man didnt you do yours or did you run across somethin and how much for the wheels mine i got now are to big

[Mad Mike]

you will need the belt side motor mount off the original motor and bolt it to the z6. Also put the water neck on the original motor on the Z6 it makes it a lot easier to run the upper hose. The original trans will bolt up to the z6 but you will need to install the clutch and flywheel to that went with the original transmission.
Did you get a OBD0 to OBD1 conversion harness?

Yes. :goodjob:

Also, for the VTEC wiring, you will need to convert to OBD1 with a jumper harness and wire for VTEC and 4 wire o2, also change the plugs on the harness to OBD1 ones for the dizzy. Or you can chip a PR3 with a P28 Map and stay OBD0, but then you have to use an OBD0 dizzy, and none of them bolt up without hacking them. Or you could stay OBD0 and use a VAFC with the stock PM6 to make VTEC work. Don't forget to elminate the resistor box if you are using the Z6 injectors, or you can leave it in and put the crx injectors on the Z6, they are both the same CC.

ok we bought a obd1 ecu from a guy and now we need the obdo to obd1 conversion harness.. cause we just dont have one..

and the z6 motor goin in is just a motor by itself no tranny came with it just motor nothing else.... someone live near monroe so they can come and give a better expanation

With all due respect it is very straight forward,If you run across any problems check out honda-tech they have tons of write-ups on this.It seems everything needed for it to work has been mentioned on here you should be fine.

good luck.:goodjob:

thanks man i think now he wants to do the mini me swap we are just gonna do a head conversion do we have to take it out to put it on or will it just bolt up without having to take out the block

[Mad Mike]

you can head swaps with the block still in the car. Just not sure witch heads can work with what blocks. I've done a 1.6 d16a6 head on a 1.5 dx block but my friend said it would work so we did it. It worked but wasn't vary much faster.

[green91]

Just use the z6 engine. You'll have to cut the timing covers for the driver side mount to fit (use the mount from your original motor). Its a EASY swap. I do them in under an hour.

[dustinkelley]

green91...it wasnt my car or choice plus it pisses me off today he said he is goin to stockbridge for a while soo now im even more pissed cause he isnt gonna do the swap yet.....but the swap is a d15b5 or somethin not sure its a HF and the new vtec motor is d16z6 sooo...he wants to make more power...not sure if it will......by putting the vtec head on the original block and



im about to trade a clutch for a set of cam gears and another ecu anyone want a p28 or dohc zc ecu dont have it here so no info on it....both stock not touched and work....

[green91]

HF makes the swap eaiser but i wouldnt use a HF bottom end, im not even sure that it has enough valve reliefs for the z6 head.

[dustinkelley]

i thought there would be a problem with it but its his car so he can do it now.. hes movin away and havin someone put it in for him now i guess........bastard

[MidLifeCrisis]

the head should bolt right up.... and as for the comment of the d16a6 head on the dx block, the d16a6 head and d15b7 heads are basically identical, its all in the bottom end..

[dustinkelley]

thanks man
