hi i have a nsr12 s3 nova and i'd like to changed the motor bearings to ceramic bearings. i visited the bocabearings site and sent them a email but i still haven't found, or recieved a reply of the correct bearings i need.

i noticed on the boca site there are:

high speed and
high temp bearings

which are better for the .12 use? i want the higher rpm, but does this mean they will explode at high heat? ie 150degrees celcius, it is the R version so i am going to run it at the required temp for max performance.

MY QUESTION IS WHICH MODEL NUMBER BEARING DO I GET? I WANT FULL CERAMIC BEARINGS.

thanks

pm me the answer please as i don't visit the engine thread often
