All this talk about the GA16de being a drop in and having the same bell housing as my GA16i has got me thinking about a switch myself, the only thing that worries me is the trouble you had with the wiring harnesses.
Exactly how much trouble was the wiring swap over and what did you use to over come the issues at hand.....schematics of the electrical layout from Nissan??

*****Yes, the wiring was tedius. I used Nissan shop manuals, for both the donor car ['93 B13 XE] and the '89 4WD B12 project car. Here are some pics of the custom 2" mandrel bent exhaust system that I fabricated from U and J bends. I ported the ex. manifold to get the outlet as close to 2" as I could. Then I bored out the stock front pipe to ex. manifold flange on a lathe, to fit the 2"" headpipe. You can also see the modified cast iron alternator bracket that I lightened up with a sawsall. The original bracket was much larger because it included the mount for the A/C compressor as well.
I had actually given thought lately to possibly preparing an adapter of sorts by having the output harness lets say from the DE engine and the input harness on the 16i for any given accessory.., and run the wiring from point A to point B between the two harnesses for proper hookup and use this as an adapter when placing the DE in place....think it would work?? I'm thinking yes. or at least hoping yes, granted not all things are as easy as they sound on paper and it may not look quite as nice....but whatever gets the job done....correctly.
thanks
I actually did wire the car circuit by circuit, but I didn't make any adapter. I did connect quite a few of the input wires from the original ecu connector, to the DE's harness. It is far too complex a process, to try to describe on a message board though. Even I don't have that kind of time and patience.

I said the same thing in another thread, blown! These swaps are done more from desire and learned application with a twist of fate, rather than being orchestrated via a service manual.

That's why you get the ENTIRE wiring harness from the car you're getting the motor from. My brother purchased the Toyota Levin GTZ wiring harness from a high school student in Japan for his motor swap, a JDM 4AGZE into his 1989 Toyota Corolla. It makes it much easier as we just had to take out some of the wiring that we didn't need and lengthen a few others as well as a couple of other things. Still not an afternoon job, but considerably easier than the wiring hell that Boost Boy and Blown310 probably went through. But we also had to convert from carburated to Fuel injection and automatic to 5 speed. Yipee! Research and understanding a wiring diagram as well as being able to use all the diagnostic equipment (Multimeters are a man's best friend in this case) is key.
On my first swap with the CA16DE, I was stuck for 3 months and all because a stinking ground wire got severed inside the engine's harness. Talk about someone who felt they had failed, "I actually cried" like a punk. I even had considered calling the junkyard to come and get the remains because it wouldn't start. So I got desperate and opened up the harness and found a wire cut I soldered it together and ran around to the driver's side to see if it will crank. It fired right up (1 rotation) and I never looked back

AWESOME JOB MAN!!!!!! thats something Ive wanted for YEARS.. Looks like a nice clean job.. 1 Question though, wouldnt it have been easier to swap the whole vehichle wiring harness and ECU instead of reworking it??? I had to do this when swapping a GA16i into an 87 E16s sentra. Along with Fuel tank and Pump. Just wondering............

That is exactly what I did! But keep in mind that the donor car was in a terrible accident that cracked the tranny case as well as crush the engine against the firewall hence the crushed wires. But even when doing a pulsar to sentra swap, there's so much reconfiguration and sorting around the dash because the pulsar and the sentra are not identical internally. It wasn't easy and I don't recommend anyone with no wiring experience to try it or you will be crying, too .

I had a great time autocrossing the car this weekend. With the AGX's and Hyperco Gen. 2 [B13] street/track springs, and the Bridgestone RE71's on B14 wheels, the thing handles incredibly well. Hey how about the creative "Sport Compact Car" magazine style picture I took on the way home?
Man blown, you always look like you're having fun in your car (that's the way it should be) . How did the car do? I never really understoof (fully) how autocrossing works, but it sounds cool.
