Difference Between Rb20 And Rb25 Turbo

[4core]

Does the RB20 turbo have a vacum line on the compressor housing, or is that the RB25 turbo?

Anyone?

I am reasonably sure that the RB20 turbo has a vacuum line off the comp housing and I think the RB25 one is off the intake piping near the throttle body, something like that. Been years since I've played with either running an OEM turbo
