cheap high compression pistons?
Does anyone know a cheap alternative for some higher compression pistons for a na build looking for about 12:1** compression? Looking to spend under $500 -

Cheap?? You could always get some high temp jbweld and pour it through the spark plug hole. Make sure to measure right so you get even compression accross all cylinders.

A high compression build and you want 12:1 pistons but under $500? I know where this is going.
its gonna cost u twice that if you go with Z32 Non Turbo pistons and rods, but still you will not get the 12:1.Gone - 1988 Shiro

i was just wondering whether you could get some pistons etc from another engine that will boost it up for that price, don't need it brand new or anything,
BTW: say i put z32 na pistons in it and a copper head gasket, what would you thyinhk it would set the compression to roughly, any real performance gains??? -

Generally from what I have seen, most Z31's running Z32 pistons generally work out to say… 9.5:1 in a Z32 but somewhere in the neighborhood of 8.0-8.5:1 on a Z31. Do not go cheap with bottom end parts, do it right the first time, get decent parts.1986 300ZX Turbo - Sold

how about unequivocally stating the obvious, 12:1 will require some serious effort on the pistons
