Send me an email at
[email protected] and I'll give you the link to the supplier. It's that top secret place Dee and I talk about. They can definately hook you up with any size/compression pistons you want.
A word of warning to those that are looking for only rings: The set of Deves rings we got came with oil rings that didn't fit. Apparently Deves didn't make oil rings to fit our 2G pistons. We ended up with Deves compression rings and stock Mitsubishi oil rings. If you want rings only, have your ring groove dimensions handy when you order.
We didn't get the pistons from this place so I'm sure if you get pistons and rings everything will be perfect.
FYI, HERE'S the link to Motortune USA break-in page.
