Rb26Dett Rebuild

[dav32]

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.

Same as normal rings. Cut to the specs given and a little bigger is better than to tight always. ".001 more" it won't make a difference.

And watch the thin ring on the gapless second they're weak and tough to get square in the bore. I just use a old piston with the oil ring left on. Puts the ring down around 10mm and square.
