just out of curiousity, what would the advantages and disadvantages be? has anyone done this yet? i just have some stuff laying around. thinking about putting things together.

rotary>piston

into an s5 turbo right?

I don't know if there are any differences in weight and stuff. The compression ratio is the same, but if the rotors are lighter/heavier, then you'll need the fd counterweight.

yeah. i have some S5 TII housings laying around and 2 FD rotors. So if I put them together, what would I need to make it a running motor? I never tried something like this. Just curious. I probably won't do it but its crossed my mind a few times.

a FD eshaft. you can mix and match but its not the best way to build....

Cheers!

the FD rotors has hardened stationary gears, and they have 3 window bearings?



anyhow if u use FD rotors, you will need the FD front counter weight to make it work right.

vosko: AFAIK the eccentric shafts are all interchangeable.



you just have to make sure you use the right counterweights for the rotors (FD counterweights for FD rotors...)



the S5 housings are better than S4. Everything S5 is better than S4 for the most part.



the FD stationary gears are better but you can also just get hardened ones from racing beat which also have the modified bearing.

i know you can interchange but it is better to have a mazda balanced rotating assembly...........
