No, perhaps the turbine but I doubt that as well.Neil wrote:i thought it was for an S14 but on S15's it was exchanged for metal? ive read that multiple times.
he is correct the s14 t28, skyline t28, and gtir t28 all use ceramic wheels, for the s15 model they went to the inconel wheel. the t28s are fine to use up to about 15-16psi anything above that your asking for problemsNismo_Freak wrote:

The RB25's had a composite compressor on one model, and a steel wheel on the other. Perhaps that is what you are thinking of.
