Rotors for Series 4

I am very near to getting my engine rebuilt. I need to know what rotors fit and their weight and compression ratio. Will someone please post that info. Thanks.

Series 4, Series 5? The engine won't care but you might. The Series 5 rotors are lighter and have higher compression = more HP.

all the rotors will fit you need to decide on what you want in a rotor.
do you want high compression?? 3mm seals??

I know that the 13b rotors are interchangeable, but I want to know what they weigh and what the CR is. Anyone? And I won't need 3mm seals.

Yea, definately go with the 2mm apex seals. That'll allow you to possibly go to the 3mm apex seals if you blow it up, without having to buy a new rotor for $500.
