Hi guys,
i built up my RB26 engine with with tomei pistons (86,5mm). The supplier manual says piston ring gab Ring 1 and 2 0,18-0,35mm. It seems very tigt in compare with other pistons (wössner, CP etc). My engine workshop adjust 0,25mm for the rings, that makes me a litte uncertain. Does anyone have experience with the tomei piston rings?
Piston to wall clearance is 0,055, pursunat to supplier manual!!!
Sorry for my bad english 🤯
My aim 550-600hp.
