Question Engine Bearings

Would I need to replace the main and rotor bearings with the three window race type to run 9000-9500 rpm safely ? , this is in a 13bREW motor .

the REW engine bearings are better than the racing beat 3 window they more oil to pass through. I would also get a deeper groove rotor bearing for better lubrication. The deeper groove rotor bearing DOES make a difference.

The REW has a deep groove along the centre of the rotor bearings.

Yeap, the REW engine stationary gear bearings have more oil inlet than the Racing beat or mazdatrix 3 window style.

Rotor bearings and stationary gear bearings are different things.
