I am trying to build a b18c1 and i have a set of Arias forged 84mm pistons; to have these work, the cylinder walls will have to be honed to about 55/1000s of an inch in a couple spots on the steel sleeves.....

i think thats more than 100/1000s over stock bore... anyway,

would that be asking for trouble, boring the cylinder walls that thin??

this is for a turbo set-up, and i cant really afford to buy sleeves at this point.

PLEASE help me with any wisdom that can be had, it would help me out like crazy, as the dudes building my engine are waiting on an answer.

i would greatly appreciate it. good day to you.

 

If you have it at a machine shop shouldn't they know what the expletive they are doing, and knowing the limitations of a block?

 

Sotck gsr block can be bored to 82mm. To use those 84mm pistons you would have to resleeve your block then bore out to 84mm. I would just sell those 84mm pistons and run 82mm pistons if you want to bore out your stock block for more displacement

 

aight then dudes i guess ill get some 82mms and sell those 84s..... i appreciate the help!!


let me know if anyone wants any 84s yea??

 

Check you PM
