hey guys, its been a while since ive been on here. i need to know the compression ratio of a 13brew. and would there be any problems with running s5 TII lightened rotors and counterweights in the rew?

oh yeah, its in a 90 TII with a single turbo, if that matters. thanks

i believe the compression is the same between s5 and 6 and the weight is the same on them as well. should be no issue running any 13b rotor as long as you run the matching counterweights

ok, thanks. now i just need to find my counterweights and figure out what turbo to use.
