Title: pistons & rods.
Post by: kowalski on May 16, 2007, 08:40:20 AM: ok, so who makes 87mm pistons for the M42?
i have the s50 ones, but i don't know if thats what i want to do because i want optimum piston top shaping with my combustion chamber, so who knows where i can get a set of these from?

and for that matter, where can i get a set of rods as well?

Post by: kowalski on May 16, 2007, 08:06:26 PM: ya, i have that already, except that they're just an intermediary for whoever is making their parts. you cut them out, and you have parts at a significantly cheaper rate. Although i am building what is close to their 205hp motor, but might actually end up beating it out...

A set of 4 custom M42 Turbo JE 2618 Alloy forged pistons with wrist pins
and JE Rings is $650 per set and takes approx 3-4 weeks to build. Any
bore size or compression ratio you want...

i guess the same is for no turbo pistons

Thats what im running, 8:1 CR, 1.5mm overbore

so far no problems with them, seem to be a great set of pistons
