Re: NEED help with 5th gen Pistons ASAP (Sorry)

taken from h22 build up info in the NA section
"While it is possible to bore out the stock sleeves on the H22, it’s not possible to go very far on them . . . . at all. In fact, the factory potential for overboring the stock 87mm is just .25mm, which will garner you a whopping 12cc’s (a 0.6% increase in displacement over the stock 2,157cc’s). On a budget rebuild (i.e. Type S overbore pistons & stock sleeves), this may be worthwhile as a “why not” modification, but don’t kid yourself about the amount of power you’ll see from doing it, aside from the increase in compression. If the improvement due to the extra displacement were measurable on a dyno, I’d be surprised.

In order to increase the bore a little more substantially, a resleeve is required. Resleeving the block needs to be done by a competent machine shop, and replaces the factory FRM (fiber-reinforced metal) sleeves with iron ductile ones. Some options available for resleeving include Golden Eagle, AEBS, Darton, and LA sleeve liners. A full-on resleeve will cost anywhere from $800 to $1,500, while replacement sleeve liners can be as little as $400 after labor. But bear in mind – stripping & shipping your block is a significant expensive just by itself."

so with 87 mm they will drop right in there without resleeving?

Re: NEED help with 5th gen Pistons ASAP (Sorry)

Don't think JUN are FRM compatible (should be a different series than others if so), so you would have to resleeve no matter what. 87mm is stock though.

If you don't want to resleeve then get Type S pistons. 11:1 vs. I think 11.5 on the JUN? Other option is Mahle Gold pistons. They are supposed to be compatible and are available in 11.5:1. Would be cheaper I would imagine than JUN anyway.

If you do go with Type S pistons, they have a slightly smaller pin diameter, so you will need to replace your con rods with Golden Eagle being about the only option (unless you get someone like Pauter to make you some custom ones).

Even with compatible pistons and 87mm stock size, your cylinders should be honed first. I wouldn't just drop them in.

Also Type S pistons come in A and B sizes (as well as 0.25mm OS) with A being slightly larger. Not sure about Mahle Gold, probably just A size and 0.25mm OS and you hone/bore a bit more material. Cylinder sizes are stamped on the block. For instance mine is BBBB.
