i need the best bang for the buck pistons available. its an a6 block, its going to be bored so no vitaras. im looking for 8.5-9.0:1 compression with stock valves and i dont have a head gasket yet so suggestions are very much welcome.im using tunertoys rods and im on a budget.

what's wrong with stock pistons then?

 

[garageEF]

its going to be bored

Just get O/S viteras or O/S A6 pistons

 

[Dweezil]

Or get O/S ZB P28 pistons. 8.7:1 C/R with a Z6 H/G if you go .5mm over.

best budget build. tunertoys rods mated to vitara pistons.

and it should land you right in your target c/r

*edit*

and OEM or FEL-PRO for the head gasket.

ive heard that going .5mm over kills block strength. does anyone have any experience with this setup?

I have a DOHC ZC motor that is bored .5mm and I have boosted it to 15psi with no problems.

yeah, .5mm or .020 wont hurt anything.
not unless you're gonna run some kinda crazy high boost, but then that'll be just as bad for a stock bore too! :lol:
oh and the z6 metal head gskts always worked good for me! but dont forget to coat it good with copper gskt spray though!!!!
