Anyone know if the det rod/main bearings (non-gti-r) are made of different materials vs. the usde bearings? From my understanding there the same materials but a builder questioned it. Due to the fact that the 300zx turbo bearings are different material than the NA version. Also since turbo cars will obviously see heavier load tha a NA car.

Same material and for the bluebird trubo motor, the same bearings. The GTI-R bearing has different oil grooves in the mains to feed the rod bearings different but the material is the same.
