On my turbo'd DOHC ZC motor i have the stock pistons in which are sorta domed i guess and i have the chance to swap them out for a set of d16y7 pistons, just woundering what you guys would do, think it would be better snice they're not domed like mine are i would assume so just getting a second opinion thanks.

 

I'm pretty sure the zc ones should be stronger, but wait for another reply. I'm Stoopid.

 

Well if you want dished pistons get the D16Z6, and those are dished unlike the D16A6 (flat) and the ZC (Domed). What is the comp. on the ZC?

 

So for boosting applications the ideal pistons would be the D16Z6? I can't get ahold of any of those so would the D16A6(Flat) pistons be better then the ZC(Domed) should i put those in over my ZC, thanks again.
