ok so have searched high and low and have not gotten a straight answer so here it goes. anyone know of a good diy for obd0 mini me swap using a y8 head? do have to convert to obd1 and what do i need? i know about the head studs deal with the y8 and could i just to a dpi swat to mpfi then just ad a jumper harness and ecu and the head swap? i am finding all kinds of different stuff but not the right answers. so any help for you guys would be great thanks.

anywho im not saying its impossible but the reason your not finding info on it is becasue people tend to stay away from y8 mini me swaps.
Z6 is OBD-1 and MPFI along with VTEC.
VTEC crossover is almost unnoticeable but it's pretty peppy for a SOHC.

You'll need to wire MPFI and VTEC, need intake manifold, complete head, Si throttle cable, and a bunch of random stuff you'll come across.
I'll be running the engine on OBD0 at first either with the PM6 ECU (with one wire vtec mod) or more likely the PW0 B16A1 ECU as I've got more experience tuning those ones.
Makes no difference what ECU you choose so long as you can tune it well.
VTEC cross over should be smooth as glass if it's in the right place.
BUT...as for the B-series... my B16A sure as hell didnt engage smoothly, it made my car hella loud and took off as if someone pinched its ass.
I dont see why it wouldn't be more benificial. It all makes more sense to me to go with the Z6 long block since you'll have the ecu for it, .1L more, and a VTEC head designed to work with the bottom end. i've seen Z6 long blocks sold locally anywhere from $75-$300. When it comes to cars, if money will allow it, keep it as simple as possible!
Depends on your cams.
However, with a stock B16 the VTEC kick is there as some sort of marketting gimmick so you get the illusion that all hell broke lose. If you actually lower it then it makes more power.
The kick happens because the torque is dropping off the low cam and comes in with a vengence on the high cam as it was already capable of making more torque before you asked for it's help so it climbs a torque cliff if you like.
Ideal location is where the torque curve for the low cam and high cam cross.
Normally stick a B16 on the dyno and set VTEC way up high and do the low cam map, then stick it quite low and do the high cam map.
Put the two plots on top of each other, where the torque curve crosses is the ideal VTEC point. It's never as high as stock.
Certainly tho some crazier cams you will get a "kick" from, but the setup should be much the same. Tyre spinning isn't ideal right ?
obd0 si dizzy bolts up to the y8 head no prob. the z6 only gets 2 bolts in.
