wiseco vs prox what piston

[TALLSUP]

getting ready to bore my 86 250r but what piston to get prox or
wiseco:doh:

[250sx]

fwiw my 250r guy swears by pro-x :shrug:

[Mr. Richard]

i am running a wiseco, a stock honda , a sudco, a pro x and i really don't see a difference,,,, the cast honda and sudco run at a tighter clearance when bored so there tends to be less piston noise but thats all ,,,,,

IMO Wiseco, cost a bit more but overall a more durable piston.

Good call TALLSUP. I am using the same thing in my 250r. IMO, i think it last longer but that my .02

Pro X pistons claim to contain more silicon the alloy mixture. This is supossed to make them more durable.

Wiesco's like loooong break-in's.

I prefer Pro-X.... Less chance of a cold seizure.
