T78 exhaust housings
 

Hi guys,

The greaddy T78 turbo comes with a choice of two exhaust housing sizes... the 17cm and 24cm... which one is more suited to the S6 13bt REW, I am looking at making 400+wrhp @ 15psi on a rebuilt ported motor. I prefer the 17cm as it should spool up a bit faster but is it too small for a rotary?

cheers

i do believe you want the 24cm one, due to the rotary's insanely high exhaust energy
