hey, i was wondering if a intake for a s13 wtih a sr20 or ka24 will work on a s13 with a ca18(JDM 180SX). same deal for cat back systems, as well as downpipes.

Catbacks will fit all s13’s  
Intake’s are not interchangable though.  
Downpipes are usually engine specific, but I have seen sr downpipes used with ca18’s before. Just make sure it has the proper t25 flange so it bolts to your turbo.
