as above is it an all bolt up and go after swapping ecu and running vtec solenoid and wire. btw, how do you do that. it is going into a 91 so it will remain obd0. i can just use the harness on my b18a cant i. help please. motor is ordered and i want to get my shtuff str8 before i do swap.

 

Swap out the longblock (and tranny if you're getting a B16 tranny), you can use the same clutch & flywheel, same starter, same alternator, same injectors, same fuel rail, etc. You need to use the B16A distributor (if you want it to bolt onto your PR3 head, or cut one of the LS distributor legs off and ghetto-rig it) and the VTEC ECU (either PR3 or PW0 in this case) and everything will plug right in. There are just 4 extra wires that you run from the engine bay to the ECU. Use the same Integra wiring harness - everything will plug right in. You need to add a wire for the 2nd O2 sensor (C8 on the ECU), a wire for the knock sensor (B19 on the ECU), a wire for the VTEC solenoid (A8 on the ECU), and a wire to the VTEC pressure switch (B5 on the ECU) and then you're pretty much set. Use the same axles, mounts, and brackets.

 

cant i just use the stock ecu and run a V-FAC to adjust fuel and engeage vtec? theres two 02 sensors for the b16? i thought there was just one? i swore when we swapped my friends b16 in his crx ther was only one. the b16a i have is the obd0 one so it is a 2 wire 02 sensor, right?
