Do you need to run race gas when using aftermarket pistons with a higher compression ratio than stock? As part of a complete motor inspection/refresh, I'm looking at replacing my worn stock 06 GSXR 600 pistons (12.5:1 CR) with some Wiseco pistons (13:1 CR) while keeping the displacement stock at 600cc. This is for a small boost in power, and I can get a Wiseco kit with pistons, rings, wristpins...

Looking for a set of L24 .040 over high compression pistons. Prefer new but used in good condition OK too. Email to TBork95577 "@" AOL.com or PM here. Thanks! Tom

I've found high compression pistons at srmotorsports and at protegegarage, but theres a pretty huge prize difference. $79 a pop at srmotorsports and $599 for a set at protegegarage. Why the big difference? Do you "only" get pistons and no pistonrings from srmotorsports or is it just the quality of the steel that differs from the two?? If anyone knows or think they do, please say so....

If you want consistent power throughout the season, stick with the OEM pistons. If you want something that makes power on the dyno when the engine is first built but then rattles and uses oil after a few race weekends then go Wiseco or JE.

do not mill your heads that far, you will not get your manifold to fit and will never get that motor timed correctly, they don't know these motors at all. They WIlL have to be custom pistons like I already told you! And you should get them in an oversized variety, so that the machinist will bored each cylinder individually to match each piston on a motor like this. If you send them a piston ...
