Hello,


I am new to this specific forum, but not to the interwebs... so, yes... I have searched... and yes, I have scrolled through the stickies... It is possible I've missed something, but so far I can't find an answer my specific question.

I have a compressor housing that I'd like to use... I will be buying a CHRA online (probably Garrett). What measurements do I need to make sure my housing matches the CHRA? Inducer, exducer, back plate, etc... Is there anything else I need to know? Basically, the exhaust size - I will be buying a T4 exhaust housing after mating the CHRA/Compressor housing.

So far, most CHRA's online just have the model number and don't appear to list the inducer/exducer/backing plate mm.

Thanks for your time.
