The vtec engine will go right in with no additional parts needed.

Then decide if you want to spend money to control the vtec solenoid and either
do it manaually,
buy a aftermarket vtec controller,
or (replace the ECU with correct ECU-get it programmed for your car-change O2 sensor pins- add vtec pins)

That thread explains how to use a VAFC2. Kpro would require using a donor ECU from a K series vehicle (US Civic Si, Acura RSX). S300 is for older Civics, Integras, and Preludes. There is also a D17 option for Ktuner but it is awfully expensive. Cheapest option is either VAFC2 and original ECU or find a VTEC ECU/harness and reflash keys.
