You could just use a set of PM7/P29 pistons from the ZC/A1 motor. Would be alot cheaper and would probably give you around a 12.03-12.5:1 compression. :TU:

But, to answer your question, yes they make them.

Pm7s are a cheap, easy way to bump up compression, but they also lead to some really sucky side effects, namely HAVING to use higher occtane (93 in some extreme cases) and dealing with tuning issues to keep the engine from pinging to death.

A better option for high compression is a PM3 piston. It will actually stick out of the hole some, which provides a rather fantastic amount of quench, lowering the octane requirement and generally making for an overall better running engine.

All this is if you want to save money. If you would like to go with aftermarket pistons, I would recomend Bisi, Endyn or Supertech.

your gonna want forged then, and maybe start out with a compression ratio of around 10-10.5:1. This lower ratio has much more room for tuning error than say 11.5-12.5:1. So, why not just deck the block(.010) and mill the head(.020-.030)? That will raise your ratio to around 10.4-10.6:1 or so? Stock pistons will take that much, maybe be more concerned with the rods...

spraying higher compression is fine, tune for it, hope your pistons dont melt from detonation. competence plays a huge part. really, u have to run higher octane? no sith? may the scwartz be with you

so me and the mad scientist dont have to replace the piston rings you just fried

The PM3s are the only OEM pistons (well..., maybe the GX too) i would consider for a 1.6 block with a P08 head.
The way i look at it, a Z6 with PM3s is the "cleaner" 12c.r. setup.

But off course, Joseph Davis' suggested PM3/Y8 combo should be something even better - though, only if done right :jesus:

those JEs look very nice bone!
