B18C1 into 92' CX Specific Stuff
I'm putting this b18c1 into my 92' CX.
1. Do I need to custom fabricate my exhaust so that it fits with the cat? Or does it just bolt up like stock.
2. What is the one wire thats missing from my harness? I have read that the 92 Civic CX's from Canada are only missing one wire, but which one?
3. Should I go either with the ACT Street Disc with XT PP ~$450 or the Clutchmaster Stage 3 for ~$350

1) Depends on the exhaust. But with exhaust, anything is possible.
2) You would be referring to the Knock sensor at D3. You will also need to wire up IAB's which is A17 (for IAB ECU signal) and A25 for 12v power source (if you're using an OBD1 P72 ECU)
3) Both are good clutches, but I would go with a Clutchmaster Stage 3.
HTH.

Re: B18C1 into 92' CX Specific Stuff (Jinya1004)
1.) yes, with the factory GSR manifold and CX exhaust, the cat will come up short. with a GSR Greddy header (same length as the factory GSR manifold) and an Apexi WS exhaust for a 92-95 civic, that we used for my friend's swap, the length between the exhaust and the collector of the header is about 22 5/8". so, you can get the difference of the length that is given and the length of the cat you have now to have an idea of how much the cat needs to be extended.
2.) since you have a 92 civic, the wires that are missing are: the knock sensor, the IAB wires and you have to convert your 02 sensor from a 1 wire to the 4 wire that is required for the conversion.
here is a pic of the location of where you would have to pin the knock sensor to on the civic's harness to connect with the knock sensor from the integra's engine harness (it is #3 in the pic and pic provided by hybrid93hatch's thread):

Well, since everyone covered the wiring part pretty well, I'll add this about the stock GSR manifold. It'll be a good 5-6 inches short, and what you'll need is either an extension piece (for some reason we have tons of them laying around our shop that showed up in a container.... PM or email me if you need one), or have your piping lengthened. Another way to solve the problem is to run a 2nd gen B16A exhaust manifold or header from a Del Sol or 99 Si. The downpipe is the same length as needed and it'll bolt right up to your cat w/out having to modify your exhaust length.

Re: B18C1 into 92' CX Specific Stuff (Newman)
I dont think that the O2 need be changed to 4-wire because all of the 92's are already wired for vtec. I did 2 92' CX swaps and that never needed to be done. As I never converted to a 4 wire set-up and my electronics work fine, no CEL's. I understand your diagram above but, i think it is different with the 92's. The only thing you really need to do is wire up the IAB to get things going. Wire up the knock too, but, I didnt hook the knock up, I just made sure I had good ol' 94' octane in the biatch...

OK... VTEC and an o2 sensor have nothing to do with each other.
You'll need to convert the o2 to 4 wire.
You CANNOT elimanate the knock sensor by upgrading octane.
You can get a p28 ecu; it does not have a knock sensor... EDIT: A p28 is an automatic ecu, so it will need to be modified.

Re: B18C1 into 92' CX Specific Stuff (w00t!)
wow you cats are ALMOST RIGHT.
you do need to add a wire, ONE WIRE ONLY on 1992 civics as long as you use the 94-95 GSR ECU with a 94-95 GSR swap.
this is the knock sensor wire.
all of your suggestions on IAB etc are wrong.
you ONLY need to add the knock sensor wire. in essence you are connecting the ECU pin to the pin on the engine's harness near the underhood fusebox near the battery.
good luck bro! its easy!
Yes you can run a chipped P28 ECU (92-95 Civic Si) but if you use the oem GSR intake manifold, the P28 cannot operate the secondary butterflies, so many guys run a Skunk2 intake manifold with a chipped P28.
the exhaust, that does need to be modded length wise to fit to the GSR header.

That's only for the 92 and VTEC harnessed hatch back models right?

yes, you need to add one wire which is the knock on the civic's passenger side shock tower harness but, the IABs aren't obsolete, they need to be wired as well.

Re: B18C1 into 92' CX Specific Stuff (w00t!)
do you have to wire the iab from the driver side harness directly to the ECU?? there is a wire that already connects to the engineside of the harness to the ecu at that spot.. i believe it went to a20.. i dont know if its internally wired to any other pinouts, but i'm suspecting it is..
also another question, if you unplug the hose going to the actuator tyat controls the 2ndary butteflies, should the actuator move, or should it not move at all?? i'm confused because I dont have another gsr to compare to.. arrgh.. and my vtec dosent seem to be working because i can't feel it...

Re: B18C1 into 92' CX Specific Stuff (92HB_HB)
Wow, finally all the smart people read my post. Thanks guys. Somewhere I read that the 92 CX from Canadia...only needs one more wire for VTEC. But since my motor is a OBDII I guess I have to do the 4 wire thing. As for the Pipe inbetween the manifold and the new exhaust, the muffler shop quoted me 120 something. But they were talking about a Flex Pipe? He was saying people that weld on a non-flexing pipe? usually crack their headers. I was thinking why I would need a flex pipe if the none of the aftermarket or OEM exhausts don't have flex pipes. Whats the deal with that?
