Hey all. I'm looking for info on machining cylinders on my H22, (boreing, sleeving) My question is can it be done? Does anyone make oversized pistons? Any info would be nice.

if its just scored you might be able to just hone it out real good and get away with it. You could also bore it over .5mm and they do sell bigger pistons.

If you have the money, I would go ahead and sleve it. It will run you around a $1000, but make sure you get some one reputable installing the sleves, if not you might have problems with one of the cylinders dropping or possibly having them misaligned.

As for how much you can go over with the stock block or how big a bore you can get with a h22... couldnt tell you. I really only have experience with b series

 

i was under the impression that the FRM sleeves cannot be overbored...
i might be wrong.

i think the max h22 sleeves can be overbored is .20 or .25
