Before I start, yes I’m FULLY AWARE of the “tHeRe ArE hUnDrEdS oF aRtIcLeS aBoUt ThIs” I know there are but too be 100% honest I can’t wrap my head around any of em, lets keep this simple I got a d14a4 (Civic 2000 1.4iS) I wanna slap a d16z6 head on it Obviously I’ll need; D16z6 head Dizzy from d16z6? Spark plugs and wires from d16z6? And a lovely timing belt My question is, which ECU and harness do I use? Do I use a d15 harness and a d16 ECU? Both D15B or both d16??? And then comes the after works, will I have to get it tuned ASAP after I slap it on or will it run just fine? I apologise for such a stupid post.
