Anyone ever use these rings before? Are they any good? Also king engine bearings?
 
The ring are good. The bearing are good to BUT they are very hard i.e. any debits or swarf thats passes through them will score the crank not the bearing.

What bearings would you suggest that i get, as block is being rebuilt?:D
 
im running nippon pistons/rings in current build and have used them in my b18 build that is ready to fit.
the guys in the US rate them highly.

as for bearings the "king" bearings and ACL "race" bearings tend to be too "hard" as mentioned above.

you need ACL "duraglide" bearings but very hard to get hold off,well they where few months back in the US and UK.
