I made a lot of search and found nothing about using 82 mm pistons in B18c engine

Some people had problems with this big bore on stock sleeves?

thanks for your help

 

Naw, its probably the most you would ever want to go on stock GSR sleeves, especially if you're running high CR or spray, even worse if you Boost. I plan on going 82 on my next build, im at 81.5mm right now on one of my blocks.

 

82m is okay... i have a GSR and a LS at 82m right now with ITR and CTR pistons

 

Running 82mm at 12.5:1 compression and no problems (that I know of)....

N/A is fine with 82mm sleeves, but boost is a big no-no.
