Turbo mini-me Q.
 

Hey everyone I am getting ready to build my mini-me (a6-z6) Now I have some z6 pistons laying around an I used compresion calculator an it came up with 8.94:1 Do you think that is low enough to boost 10psi on a 14b with hf mani? I also have arp rob an head bolts. Thanks for any input

Re: Turbo mini-me Q.
 

Yea i will be doing the same set up with a6 pistons, only 8psi though...

Re: Turbo mini-me Q.
 

It's fine. I'd have no problem tuning a 10:1 compression motor.

Re: Turbo mini-me Q.
 

Just tune it right and you'll be fine, all stock B Vtec motors are over 10:1 and they boost nice :y

Re: Turbo mini-me Q.
 

The only reason I brought it up is because everyone said that the a6/z6 mini-me is too high comp. to boost safely so I was thats why I was thinking about putting the z6 pistons in there cause they are more dished than the a6 ones.

Re: Turbo mini-me Q.
 

Do you know how to swap pistons out? You'd need to hone the cylinders, get new rings, and take everything apart and its a headache unless you have a nice place to do it.

Yes I know how to swap out pistons. I have built alot of honda motors. But mainly all n/a. An I am now wanting to boost.
