I have bought an R32 GTS-T and i was told by the guy i bought it off that it had a RB25 neo turbo/ an op6 on it. i had it on the dyno today and bumped it from 8 psi to 13 psi and it went from 127Kw to 166Kw but i still dont know if the turbine wheel is ceramic or not. i need to know if i can keep running it at 13 psi or not does anyone know if they came out only with ceramic wheels or is there a steel turbined op6.
