The series 2 RB25's had a Nissan badged turbo with a plastic composite compressor wheel to help spool the turbo faster.

The series 1's had Garrett turbos with steel compressor wheels.

Both turbos have ceramic exhaust wheels.

My turbo says Nissan on it, I dont remember Garrett badged anywhere though, I could be wrong...I believe that the compressor wheel IS steel on mine though...
