I want to swap a 97-00 b18b into my ek6 97 civic hb and also ref. it. What kind of engine harness do you need? What do you have to rewire? What motor mounts is require?

 

You need the Si rear tranny bracket and driver side block mount, all Civic rubber mounts (and top tranny mount), and all other brackets from an Integra. You can modify the EJ6 harness since neither the harness and engine have VTEC.
