97 Civic Hx With 95 Civic Si Head Won't Start

[coronamoto]

I have a 1997 civic hx that I had the head, head gasket, and distributer replaced with a 1995 civic si's. To my understanding they are the same engine, everything is put together, but the engine won't turn over. Any suggestions? Am I wrong about the engine's being the same?

What detail do you need? It's a friends car and the guy who did it flew to Alaska before he could get it working, and now I'm trying to figure out what he did wrong. The engine is cranking but not turning over, he said he put the timeing belt back on properly. I just don't want to start ripping this thing apart trying to find the problem, I was just wondering if anyone has done this before, and if this combination (97 civic hx bottom with 95 civic si head and distributer) will work.

i dunno but y not check your spark, never know. maybe with the new distro the wires didnt get put on correctly to the plugs.

yeah thats a real good call .. check the firing order of the spark plugs. infact now that you say that.. thats probably what i'd say it is

1,3,4,2 starting at the lower left of the distributor cap and rotating clockwise. the cylinders are numbered 4,3,2,1 left to right.

Well, a 97 is an OBDII, while a 95 is an OBDI. Did you change the distributor to match the ECU? That's where I would start. You need to match the dizzy with the ECU, whether you use both OBDI's or both OBDII's, but they need to match.

ahh missed that.. good call

no I didn't check that. the 95 si head and dizzy have to go with a 95 si ecu? I'll check to see if he changed that. Thanks guys.

The head doesn't matter, but the dizzy and the ECU have to be the same OBD version. Well, the head does matter if you're using a VTEC head with a nonVTEC ECU.

Howdy everyone. I am new to the forum, but I am also doing this swap, sometimes called a MINI-ME. The head is probably a d16z6 if it is from an Si. You will need to use a P28 ECU and a distributor from a 95Si. Also, there are different computers for manual and auto transmissions. Another thing you will need is a jumper harness if you plan on using your existing engine harness as the newer OBD2 Cars have 4 plugs while the p28 ECU has 3. Sorry if this isnt much help. I am also running into trouble adapting my harness to my distributor. Hope to be done soon.
