We can only do these in one bore size and one compression, so there has to be an agreement on which on it will be. We think the 88mm 12.5:1 would be the more safe and common application to go with. We've got the pricing down so anyone that is interested, please PM us.

Also these are only for the VE/VVL application. Not DE/DET.

Interesting. VEry interesting. What about same cr and 90 octane with 10% ethanol? Any expereince with that?

Sorry to go off topic.

@ Mazx, I know this is a 88mm thread but do you know if CP would do a 11.5 cr 86x86?

Thanks

Peace

Why could they not be used in a 54C engine block?

Im sure you could however it would be .7 compression lower on a de/det head and .9 lower on a GTIR head. So just take that into account. A 12.5:1 VE piston would be 11.8:1 on a DE/DET
