taking out my n14 and putting in a c15 need some pointers

well my n14 locked up on me. so now i think im going to swap in a c15 cat i think i can get a rebuilt one for around 10k. has any one done this on here
that might be able to give me some pointers.

i think i found a place to get the wiring from. and i know im going to need the coolant tubes and cac pipes. what other problems might i run in to?


thanks for the replys
