The Motor The Gen 1 B16a is the most popular B series VTEC swap into 4g Civics. It's the cheapest VTEC B on the market and makes pretty good power. It's definately a fun motor and if you got the money, why not? The Swap Parts Needed For the swap your going to need your stock Si harness if you have an Si or multi-point converted Dx harness, a VTEC subharness (or the plugs that plug into the knock sensor, VTEC solenoid, VTEC oil pressure sensor, and the 2nd O2 sensor) mounts, shift linkage, Pr3 ecu, 90-93 Integra throttle cable, 90-93 Integra axles, 90-93 Integra rear mount bracket , and a small ecu pin. If your going to put a mount on the front of the tranny you need to get one from a 90-93 Integra and weld a bracket to attach the mount to the front crossmember. You also need Si or Dx spindles if you have the Civic Standard. Dropping Motor In First things to do are grind the front motor mount bracket off the front crossmember (not necessary but looks better) and dent the frame rail in for alternator clearance. Then bolt the rear mount on the rear crossmember and the mount on the timing side of the motor on. I dropped it in putting the tranny side down under the mount. Then bolt the driver's side mount to the car. After thats secure put the tranny mount on and raise the motor up and secure that mount. Now for the rear mount. I bolted it on after the motor was in the car. This seemed like the easiest way. Wiring Your wiring harness has everything but the Vtec wires. You have to tap these 4 into the ecu. Looking at the diagram of the ecu plugs wire the VTEC solenoid into A8, the VTEC oil pressure into B5, the O2 sensors into C8, and the knock sensor into B19. There isn't a pin in C8 so you need to get one. I got mine off of Ebay.  Now all that's left is connecting your radiator and heater core hoses, fuel lines, and vacuum lines. The pictures below are vacuum diagrams from a stock Si motor(d16a6) and from a Del Sol Or Civic with a B16 in it. I used both of the diagrams to complete the vacuum lines.
