im wondering would i need to change any of the wiring or ecu to make this swap work. i just got a v-tec conversion for the motor and i would like as much help as i can get to make this work properly like stock with my rpm and mph gauges working

 

so will you be running a b20/vtec conversion correct? you need to wire up the vtec switch and a use a vtec ecu... https://honda-tech.com/zerothread?id=1538003 if your not running a vtec head, its plug n play.....
