Civic B16A Swap Imformation

I purchase my B16A engine complete with Y1 tranny and PR3 ECU. It came also with AC compressor, rear engine mount bracket and passenger side tranny bracket.

Before the swap is good to check everything is ok. Change the timing belt, water pump, etc. Is better to change it while the engine is out of the car.

First I took out my old good D16A6 and clean my engine bay. My budget was tight at the moment of the swap so I did the swap myself. 

The engine mounts was my first step:

The Driver side engine mount is from an Integra. For the rear side mount, I modified the rear bracket that came with the engine and I moved the rear factory mount to the second set of holes located next to it in the rear cross-member. For the passenger side mount I just fabricated an adapter that let me use the stock OEM Civic mount location and the OEM civic mount. The front mount I made my custom one using one Energy Suspension Bushing

The second step was the drive axles.

The drive axles that I used for the swap are from a 90 Integra that I purchased from a local Pep Boys store. There are a very informative article about Axles at the HaSport web page.

Third was the shift linkage.

Simply I took the Civic shift linkage cut it and I took the shift linkage end that came with the Y1 tranny. At one side (the Civic shift linkage side) I welded a long screw, and in the other side (The SiR end that came with tranny) I welded a nut. I did this with both sides of the shift linkage. This setup let me adjust it just by turning one end of the  shift linkage. 

Fourth was the engine wiring part.

Since my Civic is a 90 Si. I just need to add just four cables (oil pressure switch, second o2 sensor, VTEC solenoid and knock sensor) to my wiring harness. Then I just took out the Si ECU and plugged in the SiR ECU.

Fifth was the final mods.

The throttle cable is from a 90 Integra. It's easy to swap. Just take out your old one and install the Integra one the same way that the old one was. The clutch cable is the Civic stock one, works fine.

I have the B16A manifold for now, the connector of the B16A manifold is inverted so I took my Civic to a local muffler shop and modified the pipe connector so I can meet it to the B16A manifold connector.

The fun part, Testing the B16A.

I took my Civic to test it. The VTEC kicks in at 4900 rpm. I can really feel the pull of my Civic when the VTEC activates, also the engine sound changes too. The rpm limit seems to be 8500, since my factory tachometer doesn't have numbers after 8. It also have the 112mph speed limit .

Well Its a big difference over the stock D16A6 It's really worth the effort of doing the swap myself.

Remember there are mount kits that make the swap easier. Like HaSport B-series Mount Kit for 88-91 Honda Civic/CRX, and others. It's depend on the budget that you have to do the swap.
