as the topic says, im looking for the width of the top ring groove, second ring groove and the oil ring groove on the 88-89 d16a1 pistons. Thanks for the info!

 

haha welp looks like i answered my own question

Heres what it says, these measurements are for ring width so you know which rings you can use with specific pistons (top, second, oil)

D16A1, A6, Z6: 1.2 1.5 2.8
B17A1, VTEC: 1.0 1.2 2.8
B18A1, B1, C1: 1.0 1.2 2.8

so it looks like most d series stuff is interchangable, same goes for b series. I looked for this stuff since I remember people saying only use rings that're specifically for your piston and since i don't have part numbers lying around I couldn't compare them. hope this helps other peeps out there too
