Hi all, Just building a rb26dett engine with sps (special piston services) pistons with perfect seal ring set (PS1). The piston is 20 thu oversize not sure in regards to ring clearance because second ring is gapless one.
If anyone has used this rings set or has experience with this combination it would be appreciate it a lot. Not sure to fellow the clearance given or go higher. On the sheet with the rings set it says turbochargered engine.
- Top ring 0.005 - 0.007 per inch of diameter bore.
- second ring Gapless 0.003 - 0.005.
