R34 gtr turbo
 

I am getting some bits together for my turbo setup, and I can get a hold of a ball bearing t25 from a r34 gtr skyline. I think the turbone a/r was .48 and compressor was .57a/r

The guy tells me they held 15.5 psi till 8000 on his 32gtr. Do you think it would be able to hold 12 psi to around 7k rpm on a mild 1.6? I just wanna get some opinions from some people with more knowledge than me.

Cheers, Tim

they may be out of their optimum efficiency, you should be able to make boost real quick though, but i think you'll be ok at 12psi-this is jsut an opinion, im by no means an expert here, im sure those will step up soon and correct me
