Could i use the y8 intake manifold with the y8 head on the a6 bottom withjout switching to obd0?
For activating vtec, i can use a buddy club vtec controller, correct?
If you guys coule help i would appreciate it. THanks

We just finished up one of these.

The Y8 head will fit your A6 Block.
- Remember to pull the oil jet.
- Have both sets of head bolts handy, and check thread engagement to determine which to use. They are different.
- Your OBD0 distributor will work fine with the Y8 Head.
- We used the stock A6 manifold on the Y8 head, just because it was already set up with the car and we didn't have to futz with sensors and cable fitment.

You can use many different things to activate VTEC
- VTEC controller
- RPM switch
- TurboEdit with the A/C Hack (You loose A/C to gain VTEC control)

Other notes.
- Have both of your water outlets handy.
- Consider using ARP studs.
- Use the Z6 timing belt (I think)
- Use an adjustable cam gear to correct the cam angle.


When VTEC activates on a MiniMe, the world pretty much stays the same.

Welcome Noob, Hope that helps.

craig, to add to the head stud bolt thing, since im in a nice mood. when using 88-95 block and 96+ head all bolts are used for that block except the one nearest the vtec solenoid, that one has to be a 96+ bolt or 88-95 bolt w/ an extra washer.

hell yea nignogs, thats the good ----. thanks.
p.s.
what about the fpr, becuase the y8 one dont bolt up to the a6 intake mani.
also, why do i need to check for engagement? You mean to make sure the threads arent tweaked. (head studs)

so if you are using all head bolts from a 96 plus motor. you are good.

no the 96+ bolts are shorter, thus the reason you need to use 1 of them in that far corner. like i have said, use 9 88-95 studs/bolts and 1 96+ bolt closest to the vtec solenoid. or all 88-95 bolts and a washer on the one closest to the solenoid.
