Hey Guys,

Soooo Lexus does not want to fix the misfire on my GS because "it's not enough of a misfire to meet the bulletin qualifications". Bunch of BS!! I really love my GS and I would like to rebuild the engine. Ive been searching for aftermarket pistons/rings/bearing to replace my stock ones but no luck. If I am correct stock is 87.5mm. I would like to bore it out to 88mm. Does anybody know of a company that sells aftermarket pistons? Thanks guys!

Any of the aftermarket companies will make you forged pistons based on the stock ones, you need to send them one and they can do it for you.

I would chose Wiseco.
