I did search this up. and no one really answers the question i want to ask. but. for stock d15b pistons. where do most of you get your rings from? some people "think" that z6 piston rings should work. but no one really knows. I ordered d15b7 rings. and nope. they didnt fit for nothing. not even close to fitting the top and second compression rings. so tomorrow the z6 rings should be in. but if they dont fit and i dont want to keep doing trial and errors. being florida doesnt have a "JDM-R-US" I also know that the z6 has the same P08 piston code. not really sure. but if i remember correctly. so if im wrong on any of this. correct me. and guide me to the correct answer.
