i order new pistons to for my h23 i had 87mm BRC 9.8:1 pistons and i had a problem and melted 2 pistons in on just 15psi so i ordered some raceeng/wesco 87mm 8.5:1 pistons and i did want that low of comp but all they had was 12.1:1 and 8.5:1 in stock so u know i did not want 12.1 but i been thinking about getting my head milled 20thousands to bring my comp back up to about 9.5:1 do u think this is a good idea or not

 

info

 

dont mill your head, that is BAD. let me repeat, DONT DO IT. Are you keeping stock sleeves? You can only use the same bore pistons as stock if you dont plan on resleeving, im sure you know that. I recommend waiting till they get in the compression pistons in stock or having them custom made.

 

its all ready a built engine sleeved and all

i paid for the pistons all ready they be here Wednesday

 

and i got h22 pistons thats was i had before


what wrong with milling the head people do it all the time

it'll throw your cam timing off

 

it will just advance the cam timing a little right
But cam gears can fix that

 

DONT MILL YOUR HEAD. period. end of story. Is your block 20 over? I know JE has 9.0:1 pistons 20 over, and race engineering should have them in stock.

 

i got the 87mm i went with the stock bore i got h22 pistons not h23 piston but there the same any how

i may just have to deal with the 8.5:1 and just turn the boost up even more

 

I just installed my set of Weisco B16 pistons and they are nice. They are much lighter than JE, which is what i previously had, with there new design and alot cheaper. I think you will like them!
