This is my how to: I am no expert and their are other ways to swap in a engine but this is what I did and it worked. This is for a 99-00 Civic Ex Manual 5speed and the donor motor is a JDM B16A gen2 obd1 motor. Some of my info will work on other motor swaps and cars, but this is directed towards one application.
The start:
Ok as some of you make know my car has been out of commission for about a year. I spun a rod bearing in the d16y8 motor I had. Instead of doing the cheap thing and replacing the block I decided I wanted something with DOHC. I decided to do a budget swap because house payment, school payment and other s**t payment I really did not feel like spending MAD money on a swap.
Finding the motor and tranny
I went down to a local shop that sells JDM motors http://www.japaneseengineimport.com/eng/home.htm and looked around. Before I went here I tried my local junk yard and they were trying to rape people on prices. So I kept looking an at japanese engine I found a b16a complete longblock that came with all sensors and jdm engine harness. Make sure you get this harness.. So I was on my way.
Next I had a friend selling a 94 gsr tranny with linkages, axles,int shaft, slave cyclinder, speed sensor, and flywheel. Ordered an exedy clutch and b&m short shifter with shifter stabilizer kit. As you can tell gsr axles will work on a civic application.
What kind of ecu?
As you all know in order to get a obd1 engine to work in a 99-00 obd2b(yes 99-00 all civics are obd2b) car I had to get a conversion harness. I picked one of those up at www.jhpusa.com.
Now it was on to look for an ecu. Local guy had one he was selling that was a chipped p28 running a skunk2 program (no ebay crap). Of course you can use a p30 ecu or any other chipped ecu. But the p28 is a real good starting point.
How to Keep AC
So I had everything or so I thought.
I knew I wanted to keep my AC, some of you that don't want to you can skip this part. But for me this was no option I wanted the AC. So what to do? When I took out the d16 I kept the compressor and lines all hooked up. Smart idea. You really don't want to break open the AC lines, cause then you have to go through the whole process of recharging the system. After researching I found out you can use two different brackets to adapt your d16 compressor to a b-series block. Either the p30 ac bracket off of a usdm delsol (must be usdm, I had a jdm p30 ac bracket that came with the swap but it did not work). You could also use a p7j off of a crv with b20 motor in it. So I went to the junk yard and picked up a p7j crv bracket for $25. For the belt I used a civic ex supintine(sp?) belt. The b16 ac belt was to long and the ex belt works but I would almost go a size smaller, because the tensioner pulley is really close to a bracket off of the block, so a size smaller belt would do a better job.
Keeping Powersteering
Yes, I know a lot of people don't keep the PS either. But I wanted this car to be all functional with all options I had before. So I wanted to keep the PS. Shouldn't it just bolt up? No. So my PS from the d16 was still hooked up in the car. I did not want to disconnect the lines and drain the fluid and then go and find lines to make the b16 PS work that came with the long block. To much of a hassle for me. So you are saying you can use a d16 ps on a b16? Yes. Took my d16 PS pump and I swapped on the B16 PS pulley. You don't have to do this but I found that the b16 PS pulley is smaller then the d16 PS pulley. Also since I had the ps belt that came with the b16 longblock, swapping the pulley would keep the same length. Ok so now we are getting ready to install the d16 PS pump on the b16 block. The bolt on the bottom can be re-used. I had to use a longer bolt and nut for the top mount on the PS pump. The d16 PS Pump adapting to the b16 block is easy.. One thing I wanna add is the ps bracket on the head was a b16 bracket and the d16 ps pump bolted right to that.
The Motor Mounts
Well almost done right nope. As you all know you need a rear "L" tranny bracket. Your d16 bracket will not work. You must have a 99-00 si rear "L" tranny bracket. I ordered all my OEM honda parts from www.hondapartsdeals.com. They had the bracket out to me in 3 days. The longblock came with all the mounts that are attached to it. You can reuse mount on the rear crossmember, the chassis mount on the driver side, the chassis passenger side mount can be reused from the d-series as well as the tranny tension mounts located underneath the frame rail on the passenger side. Now is a good time to upgrade the mounts. I also installed polyurethane motor mount inserts. So for this step the only brackets that I had to buy were the p7j ac compressor mount because this not only bolts the compressor to the block but it also mounts the block to the frame rail on the drivers side. I also had to buy a 99-00 civic si rear "L" tranny bracket.
