obd1 question

hey im converting my mini me to 0bd1 now and had a few questions. ok the setup is zc black y8 head and y8 manifold. with the y8 manifold i am missing the idle air control valve. can i use on off of the z6 manifold or does it have to be the y8 iac. also what throttle body should i be using i dont have one except the zc tb. also with the injectors do they have to be rewired using diffrent clips and do they still use a resistor box. thanks Paul

If they are the stock y8 injectors then they are saturated and do not use a resistor box. The IAC should be ok, and you can use pretty much any throttle body made by honda..id recommend a b series if you can get one or the h22 ones, do a search and you can find all the sizes listed on one page.

right on i found a gsr tb for a great price so i think im going to get that also found a b16a1 tb for cheap also you guys recommend one over the other. thanks again for all your help now its just waiting for parts to get here and then for the snow and salt to go away.

Whichever one is bigger, but if you don't plan on making more than 300 HP, I wouldn't worry too much about having a huge TB.. you can google the sizes, the only diff besides bore size is the throttle cam diameter and pull angle.

Bore size is the only part to pay attention to. Bigger bore == more airflow, as long as you port match the intake for it..

Isn't the Y8 mani the stupid looking one that has the TB standing up straight?

[FrodoGT]

No, the y8 mani is the best flowing d series IM available. It looks like a big bloated log, but does not stand upright.

hey i was just thinking about all of the parts i just bought to do this obd1 conversion and remembered that the z6 dizzy dosent just bolt to the y8 head so my question is can i make the obd1 dizzy fit or do i have to get the y8 obd2 dizzy. should have asked before i ordered. i am an idiot

[FrodoGT]

I think the only different one is the z6.

[pbrizzle86]

yeah the z6 is the only diffrent one from what ive read. but i bought a z6 dizzy and i have a y8 head so i was wondering if i can drill and tap new holes or if they are not even close to being able to work

[FrodoGT]

Well you could always use a thin piece of metal and drill the holes like an adapter plate.. or cut the ears off and match up as many holes as you can.

[Christ]

take a piece of thin aluminum, like 1/16" thick, and make an adapter plate. the Cam engages the dizzy by a 1/4" or better, so you'll be fine there.

Either that, or sell that one and get any other dizz that will fit.

You could also RMA it and get the right one, if you don't mind paying shipping and restocking fees... it's easier to make the adapter tho, and nice to have for the future, when you get the right one and find someone else that made the same mistake..

There actually used to be a guy selling milled aluminum plates to adapt any dizz to any head, including Z6-other on eBay, but I don't think he's on there anymore.

I've made a plate for a 'teggy dizz to fit a B2 head before, used some 20g sheet metal and a couple machine screws w/ nuts, to attach the dizz to the plate, then used the dizz bolts to bolt the plate to the head.. added benefit, you can set it up for more timing play if you want.

[pbrizzle86]

sweet that is a great idea. i think i will be going that route for now. thanks
