What are the sizes for the guages in the EVO MR..becuase i think im going to change my boost guage that reads real psi because the one in the MR is in different units..thanx

 

52mm gauge should match the stock one ok, i would go with omori or defi gauges, best gauges out there imo

 

If you're talking about the sport meter kit, the gauges are 43mm. I think you'll have a hard time finding a replacement, especially one that reads in psi. If you're going to do gauges, you may be better off getting a larger one and mounting it somehwere that you can read it more easily.

 

What he said, the sport meter gauges are way too small to be 52mm ... I know its 40something ...

 

good idea
