FS: S50 Pistons and Rings
« on: April 10, 2011, 07:32:35 AM »
I have a complete set of S50 pistons and rings for 4 of them for anyone doing a project that would be able to make use of them - they're 86mm bore.  Will post pics soon.  I paid $150 shipped with the new rings so looking to get as close to this as possible.

This is a great deal guys. Someone should jump on this! New rings will run you $100+ shipping alone.

Cheers,

You're not alone.  Nobody will buy my S52 pistons either.  Let's hope it's just tax season.

Yes, you'd need to bore them to 86mm.  Advantage is "there's not replacement for displacement" when making power (at least the non-aspirated kind).  Can also be used as the basis for stroked m42 variants.

Recipe for S50 pistons: Bore block to 86mm, get M44 2.04mm HG, Deck the piston 2.65mm, cut valve reliefs into pistons, get a set of 138mm connecting rods, attach to a M47 crank and away you go! A perfect set up. Minor machining on the crank.

Then you have to option of lightening valve train parts and porting the head for power.

A major write up coming soon....

Cheers,
~Ralph
