So I just bought an EVO X intercooler and am currently sourcing the pipes, I bought the UICP but so far none of the parts I bought have couplers on them.

My question is with a full assembly replacement, what size couplers and what length will I need to fit all the pipes and everything to my RA?

This is assuming I have absolutely no couplers. So I need one for the turbo outlet to the UICP and one for the inlet and one for the outlet of the IC and probably one for the LICP to engine manifold
