The stock 25 turbo is a T3 compressor side with a special exhaust side. It is not anything standard. I believe it was made by.. Hitachi? Ceramic exhaust wheel. Oil and Water cooled.

It's not bad for a stock turbo. It's not 'great' or anything, but put a 10lb (RB20) WG actuator on it and it works better than the factory 7lb.

I don't know if anyone has spent the time to compare the A/R or anything. I'm thinking not..

It would be a great turbo if it didn't have a ceramic wheel and break so easily. Nitrous + Meth would make it soooo fun.

Ricky I thought that it was a Garret unit.I read somewhere that in the late 80's-early 90's Nissan was working with Garrett/Air Research.Also the Turbine is larger than the Compressor or is that a typo?
