what am i gunna need to swap my lsvtec (b18a1 mated with a b16a head) into my 1996 civic ex?
i know im gunna need mounts but what about the SOHC to DOHC vtec?
do i need a new wiring harness?

 

Get B series mounts. Your current wiring harness should work fine, but i would consider running the P72(1.8l VTEC) ecu for the LS motor. Also take into consideration that in order to keep LS/Vtec running in the long run, think about investing in a balanced crank, and new rods/pistons. For some reason, people who tend to just slap VTEC heads on a stock LS bottom end up blowing them up quickly, which is due to the fact that the LS bottom ends werent designed to be Rev-happy like the GSR and ITR blocks.

 

DC2 mounts, with a 99-00 Si rear mount. Use your stock harness, and wire it to your engine. OBDII --> OBDI conversion harness, chipped p28.

p72s are much harder to find,

 

whats a p28 0ut of?
