- Fri Nov 02, 2007 10:10 pm #28325 yea well im getting a full b16 swap off a 99 civic si, i am planning on installing it on my 94 civic hatch cx. What i need to know is what kind of process will i have to go through with wiring for this engine other than vtec, and i heard some guy say that the b series axles wont fit my cx submodel, is this true cuz as far as i know its all the same.

- Fri Nov 02, 2007 11:39 pm #28343 you need to use the b series axles and they will slide right into your current cx hubs. You will want to upgrade your brakes soon after the swap though. You will have more power and a VTEC crossover you will want to hear on a daily basis and your stock brakes wont suffice.

As for wiring, you will need to rewire your 02 sensor to a 4 wire and add the wires for the vtec and knock sensor. You will want to get a P30 or a chipped p28 to run the motor. You will also need a OBD1 distributor so you dont have to swap over to the OBD2 system.

- Sat Nov 03, 2007 5:40 pm #28404 it all works just drop it in, axles fit, wire for 4 wire 02 and i think you might have to wire it up for Knock, might be easier just to get a EX/Si engine harness from 92-95 civic, and go from there, and you'll need integra mounts, or B series mounts for 92-95 and get an OBD1 Dizzy and convert all the other things to OBD1 thats needed to be converted

99-00 B16a ecu isnt a p30. the Delsols ecu was a p30. You cant use the obd2b ecu in your car.
