92 CX hatch, i will be purchasing a gsr motor....soon...
what will i need to buy...i think that i will be buying it from hmotorsonline on there it says it needs axles, shift linkage, and mounts...

axles: do i need special axles to fit in my hatch? What axles do i need to buy?

shift linkage will be the same between the gsr and the hatch right?

mounts: do i need to get new mounts of can i use the stock ones i have, i know i should buy them, but what is the reality?

obd1/2: if i get a 94-95 gsr motor, do i need to worry bout this stuff?

oh yeah...almost forgot....the catalytic convertor to...whats the best way to do that? I know it needs to be made longer, but on the cx i have the precat and yea.. Do i need to buy a aftermarket header as well?

i think thats all...anything else you can think of let me know...please?!?!?!

No special axles, just 94+ integra axles

No, you need 94+ integra shift linkage

You need the rear transmission bracket, the A/C mount (get a del sol DOHC VTEC A/C mount to keep your A/C, p54), and the front side transmission mount from 94+ integra.

IF it is OBD1, it is pretty much plug and play (if it is USDM, IF JDM, you have too use you stock harness or get a GSR or 92-95 EX/SI harness). You will have to wires up knock and IAB(for the GSR or EX/SI harness, if you reuse your CX harness, you will have to wire up Vtec to the shock tower harness and wire up the Four wire o2.). All 92 model civics are pre-wired with Vtec from the shock tower to the ECU. IF it is OBD2 (usdm), you will use the Stock OBD2 harness and plug it in to the CX harness (shock tower) and run IAB and knock sensor and get a OBD1 p72 (GSR) ECU and you are set. IF the swap is JDM, reuse your stock harness, and you will have to rewire the dizzy, alt., and injectors. or get a OBD2 GSR harness and run a OBD1 p72 (you will have to run IAB and knock to the ECU).

Just take it to a muffler shop and extend the pipe.






Thank Katman and poison for the diagrams.

EDIT: for the four wire o2 if you have to rewire it.
O2 Sensor Input - WHT to D14 (needs to be a shielded wire)
Heater Control - BLK to A6
Sensor Ground - GRN to D22
Sensor Voltage - BLK to A25 or B1

holy crap....thanks that was a amazing answer...i think im ready now....

one more question, when purchasing a cat back system...should i get it for the Si hatch, or does it matter..

does not matter, any 92-95 hatch trim level will work.

No, it matter what OBD the swap is and what harness you use.

i did this swap just a week ago, runs great motor is an obd2 , i didnt need to change any wires i just pluged my stock harnes into the one on the motor, and got a obd 1 and plugged the car into that , runs great, no codes, and once in a while the speedometer will drop out and not work, basiacally thats the only problem, and vtec wiring is project for this week

Nice.....Excellent info.. Correct me if im wrong, but if you end up changing your cat you can go with an integra cat to make up the space in your exhaust so it will bolt right up to your civic exhaust and header.

if im putting a b16 2nd gen into a 93 ex coupe eg will the rear mount work or no?

you have to have a 94+ integra B-series mount trans bracket, but the stock (civic) mount will work.

The B16 header will bolt to the factory Civic exhaust without any mods. You can use an Integra or Civic cat because they are the same length. The GSR header is the one that will come up short, about 4" short.
