Looking for overbored stock pistons for an h22a1. I'm wondering where I can find them and what size is the biggest they offer. Trying to find some solutions other than getting it resleeved. I haven't pulled my head off yet and I don't know the condition of my walls, but if it's not too bad, one option is to hone it slightly and get new pistons and set the end gaps a bit bigger.

If the walls are a bit scratched, I may need to overbore .5 and get bigger stock pistons. If worst comes to worst, I will need to resleeve but for now, want to know where and how much overbored pistons are .

Thanks

As far as stock, I believe they make a piston .025 over.

I don't think they make them .050 over though.

also, overboring .5 may be too much, frm is very slim...

 

the helm manual says .25mm is overbore. basically if you have to go beyond that they recommend getting a new block instead. or you can do replacement sleeves.

 

Thanks for the info guys! ****, looks like I may have to go with another block or resleeving, but I won't know until I open her up...by the way, how much are oversized pistons compared to after market ones like ge or wiseco?

EDIT** I just saw some prices on that link. My bad.

 

darton makes sleeves first u are going to have get your block boring darton sleeves can be enlarger from 87mm to 89mm or just 87mm pistons.
wiseco makes very nice pistons for a h22 u can get them in 87mm 88mm 89mm if i was u i would sleeve your because u can run more boost if u have turbo sleeve are a must .email if u need more help brad5dimes@netscape.net
