Rotor weights
 

Can i use a B and E rotor in the same engine

Nope, you shouldn't. The maximum allowable difference is one letter.

thanks

wut about 2 front turbo rotors?
like one that has D E on one
and the other has D and then [E] on the gear side..

Is it a badidea to use a B & D rotor in a 13BT?

What is better rotor to use for compression 2mm or 3mm seals
and RX4 or FC 13B rotors.

If anyone can help me thanks in advace :icon_tup:

i would think that used should still turn the same direction as originally. if u use 2 front rotors then the one u use in the rear will be turning the opposite direction than it originally did. front and rear should stay front and rear. like with lifters in a piston engine, they go back in the place where they came from.

As I said, the maximum allowable differene is one letter.

While front and rear rotors are the same, once they have worn down inside an engine, they should only be used in the same position they were originally installed. The apex seal grooves wear asymmetrically so swapping the direction of a rotor after 100K isn't a great idea.
