OEM or aftermarket bearings and rings?

[Suprafast0422]

Im doing a mild rebuild. Reusing the old pistons and rods. I work at toyota so I can get parts at a discount. Should I just get rings and bearings from toyota or are aftermarket ones a better choice even if im not doing an all out engine buildup?

oem has been proven over and over, its all in the tune(and good working supporting mods). A factory rebuild is exactly what i am going to do for my 400-500whp goals (If this one lets go).

how much can you get rings, .20 pistons, bearings and rods for?
