hi all,
have got a set of powermax pistons with the code 20950 stamped into them,
there for a 998 with a +20 overbore, thing is one of the rings has snapped and i need to get a new set but cant find any for this piston, does any one know of any that will fit,?
cheers for any help

Ive had trouble trying to find a ring before, the only real way to get one is to find someone whos done the same thing and bought a set, then buy some off them.

its not the single ring im having trouble finding, its the whole set,
my pistons dont seem to be listed on most sites and on mini speed they are out of stock
thanks for trying though.

Oh ok, I typed in my piston part number into google, then pressed the shopping tag and it came up with a few results, you could try that. Try contacting powermax directly and ask where they may be available.

first measure the ring lands on the piston, this will give you a better idea of what rings you are after... you may find that std +20 rings will fit..

eg the top two may be something like 1.2 or 1.4mm, and the oil scraper 4mm
