Hi everyone. I'm looking for some info. Hope you could help
where can I find standard RS500 turbo spec? like A/R and trim figures?
so far I found that it had 57 trim compressor wheel and .63 exhaust housing. Correct me if I'm wrong and add any info you have.

Thanks

 

pm paul at north yorks mate im sure he'll inform you

 

Would be cheaper to call grove on me sig or a turbo place cr turbo on the other on my sig
