Swap is done, it runs...break-in time and then turbo! (pics)
I drove her around the block yesterday. Front end alignment is whack, but everything went smooth.
To recap, my car is an 87 CRX Si (1st gen...wooohoo) and I installed an 89 DOHC D16A1 (basically a US version of the "ZC") Integra engine into it. It was a lot of work. I had to rewire a shitload of stuff including converting the system to run from an electronic advance distributor (stock setup was vacuum advance), add vehicle speed sensor (VSS) capability, add the electrical load detector (ELD), and a lot of other little stuff.
Here are some pics to recap what was done...
Old engine
Rebuilt Integra engine coming together
Tranny rebuild
Many many many hours of wiring changes
Stealthy and functional gauge setup
Finished
Coming soon
With the turbo, I'm shooting for about 250 whp at a weight of about 1850 with driver.
Why didn't I go B series? Simple...cost! Installing a B series engine into this car is very expensive. The mount kit, custom axles, and shift linkage cost me more than my entire D16A1 plus all the parts to build it up.
The D16A1 bolts right in using all OEM Honda parts. The D16A1 is a smog legal California swap for 1st gen CRX's. 
My goal with this car is to run about mid to high 12's. If I wanna go any faster than that, I'll probably use a B series engine in a more modern car.
I documented every part of this setup. For full details, see my web site.

Awesome Sonny.. Being different is ok.
not to mention, I went to the Honda Salvage Yard the other day. There had to have been 30 dohc d16a in cars.

Wow that looks great. I have an older brother that has the 1st gen CRX and when i saw the first picture i swear it was my bro's. Hehe, i just replaced the headgasket, and radiator on that thing, and it was a total bitch. No room for anything, congrats on getting that thing in there, as well as the future boost plans. I remember that car was super light too....me and my dad were able to lift the rear pretty easily.

Is that discharge elbow going to work out for you? Also, do you really think you're going to see 250whp? My goal says anything over 200whp/wtq is just bonus... how many PSI are you planning on pushing anyway? It should be a MONSTER when you are done...

Thanks for the props, guys.
Jalopy: I plan on running as much boost as it takes to get the power I want as long as the compressor is still in its efficiency range. For this setup, I think I can boost about 15-18 psi and still be above 75% efficiency with the 60 trim T3. I'll have to go back and look at my diagrams. I'm expecting to need the Pulsar/Sunny GTiR's .86 a/r turbine housing to reach my final goal. We'll see.
yellowsub: The 86-87 D16A1 are an easy swap for the 1G CRX. However, both of those engines use vacuum advance ignition. You can't control the ignition timing with a setup like that. I have a Hondata and plan to use it with this car, so converting to the 88-89 D16A1's electronics made that possible. It also paves the way for me to run a B18A later if I choose to do so.

Re: Swap is done, it runs...break-in time and then turbo! (Scott - 93HB Si)
Scott,
This is what I did to keep the ECU happy for the ELD:
I was going to cut the panel apart, but I didn't want to risk damaging the ELD. The ELD has a "ring" that wraps around one of the main power wires. I figured that hooking that up would be necessary, but it wasn't.

Awsome man!
So glad to see it's in and running! I can't wait to see the turbo setup...
It's been really cool watching your build up.
