I think im gonna stick to turbo rotors. Besides, i only want to rebuild it once
if u tune it wrong its gonna blow anyway, the rotors wouldnt make a difference

Never the less, i thank you for your response.
whatever is cheaper and in good shape will get you where you want to go.
So what im getting is that there is no significant improvements between turbo rotors

I'm waiting for the day that someone walks up and hands me a set of NA rotors so I can try it. As a side note there weren't any NA FC's in Japan from the factory, and I live in Japan.

from what ive read and talking to the big engine builders in the us, canada and australia it seems the s4 t2 are the way to go for higher boost. s5 t2/s6 are the same rotor with a different part number. The s4 t2 rotors are alot stronger and can from what ive been told is some of those big power guys have s5 and up rotors actually collapesing on them. As for the compression, you wont really see a noticable difference between s4 and s5+ t2 rotors. The s4 are just stronger (and heavier ... but they can rev to 8500 no problem, do you need more revs than that on boost?). My engine is using s4 rotors, but i plan on 25 psi with race gas, im shooting for 500+ whp. So you might want to go with whatever is cheap and avaliable, because any of those rotors will get you to 350

Ya know.. correct me if I'm wrong but didn't Mazda have an RX7... 2nd gen I wanna say that had lightweight rotors? I don't know by how much but wouldn't reducing rotating mass increase the life span of the motor and boost performance?
The S4 is lower C/R, and im not sure but I think the side seals are thicker. But, the rotors are heavier. Thats why i was asking, to see if anyone switched to either and found them better.
