hey guys, ive been searching around for the better part of my christmas day now and i havent turned up anything that helps me on this subject. After this post i will continue to search, but figured id see if theres anyone out there that could help me out.

im looking for Compressor specs and Turbine specs for the turbo, as well as if anyone knows of how many lb/min they can flow.

i have 2 reasons for asking this.

1. I have one being rebuilt with metal wheels and a 360 Thrust bearing so i can take the time bomb version i have sitting on my motor off for now. Im only looking for about 300whp at this current moment in time and i would assume i could get to that if i could turn the boost up but the one i have on the car has in and out play, and i cant afford a T3T4 at the moment.

2. I eventually WANT to go to a T3/T4 but have to stay with the same sized Turbine housing due to its close proximity to my brake master. I have a heat shield going in place but i just dont want any rubbing.

Thanks for any help! merry christmas to everyone!

Phil

Aftermarket mani? Check skylinesaustralia.com . Those guys run a lot of "high flowed" rebuilt RB20/25 turbines and post up a lot of specs/dyno charts.
