Need help ordering SR bearings!!!

[FUNGC]

hey guys i know this topic has been covered in the SR rebuild thread but i need some advice.

right now i read that theres a serial number and you have to cross reference the grade of the bearing before ordering.

but frsport offers ACL race bearings with a special coat.

and they dont have the different grade, they come in complete sets. so am i safe just to order these?

and some more info of my engine is:S14 SR20DET with some bolt ons. im planing on doing a full bottom end rebuild. with forged pistons and rods.

also another thing is can i run 9:1 CR pistons with the stock ecu for now?

thanks for your time and advice nico!
