HI Guys
searched around for this but I couldnt find any answers so maybe you can help
found this thread but the answer is not there

Anyway so I know a few ppl on pp.com are running b21 (83mm pistons) in there 3G lude b20a's
Now I would like to know can I bore out my block to 83mm and still run high comp pistons or will the block walls become to weak ?
Thanks for any input
hey nice to see you here. I had my b20 bored out to 81.5. its much easier to run b16 pistons
haha still need to pay the balance on the intake manifold pm me how much I owe you again
been a while and I totally forgot about it lol
The reason I am looking at boring it out to 83mm is that I can get CA18 pistons for a good price
The only thing I am worried about is weakening the block to the point of failure
Why not run b16 pistons instead? You can find them cheap too
I have had a look at the rs machine pistons but those only go to 82mm and then jump to 84mm
why not 82mm? And there's some 83mm out there also..
I am kinda keen on those pistons as they per the price
