Now I have been doing alot of searching....Im not going to pretend like I know anything about this subject...Because if I did, I wouldnt be posting this. Im sure this is more than likely the same bullshit question you guys get all the time...But I just need an anwser, So I can move on and start buying what I need. Now theres more than enough info on the LS/VTEC everywhere...and im clear on everything but this. I have a B18A1 Block (1990-1993 Integra GS/RS/LS) I have a B16A2 Head (1999-2000 Civic Si) I have a 1997 Honda Civic Hatch (EK) ECU and Harness configuration? What is it? I was thinking a GSR (B18C1) harness and a civic si ECU (P2T) But then I start thinking thats not right. Tell me whats up guys...Im burnt on trying to figure this out, And I dont want to order the wrong shit.
