Hi Guys, some of you might remember a thread I started on B15Sentra.net several months ago. It described the start of my GA16DE swap into my '89 B12 4WD wagon. There were quite a few technical details in it, and it described getting the engine into the chassis. It's at: http://www.b15sentra.net/forums/showthread.php?s=&threadid=24244. Anyway, after being put on hold for a while, I got back working on it a few weeks ago, and got it done. I had the engine and trans bolted in back then, and needed to finish the wiring. After installing all of the B13's EFI harnesses and ECU, it was time to finish connecting the rest of the ECU's wiring to the B12's electrical system. I have seen many threads on this subject, but no one ever really describes exactly what wire goes where. Now I know why. This is neither simple or quick. It can be done, but it is time consuming and you need to have a good understanding of electrical systems in general. Oh, and in my opinion, a factory service manual for both the B12 and the B13 donor car are a must. I slowly turned the key, and heard the fuel pump do it's five second cycle. Turned it some more, and she started right up, and purred like a kitten. The engine had no idea that it was in a B12 chassis. Sweet! :D I also got to hear for the first time, my custom 2" mandrel bent exhaust system that I scratch built, with a Dynomax UltraFlo muffler. I am shopping for a Sony digital camera next week, and will post pics and give more details. Gotta go take her for a road test, and find some gravel, so I can light up all four wheels! :D

***** Hey Marty, I am as excited as you are. Wait until I tell you guys the story of the rear Subaru LSD I put in it. It's an R160, with a 3.70 ratio, the same as the original Nissan diff. I had to have some machine work done to get the Nissan axles to fit in it. The Subaru's use a male splined stub shaft that comes out of the differential. I had to remove those stub shafts, and toss them. The Nissan axles tap into the diff, just like the front ones do, and use an internal C-clip to retain it. I had to completely disassemble the Subie diff, and machine that same C-clip groove into the Subaru's side spider gears. This was not easy, because the gears are hardened. But a carbide cutting tool got it done. Next I am going to try to fit a Phantom Grip LSD in the front differential. They make them for the RS5F31A five speed [for the B13 & B14's], and I'm hoping it will fit my trans too, because the B12's also use an RS5F31A five speed. I just put a set of the 14" factory Nissan aluminum SE wheels on it too, with some new rubber. Looks better now! :D

I was reading an article on swapping an SR20DE into a GA16DE powered B13. It described how all of the wiring just plugged in. This is not too surprising, because the B13 could originally be had with the SR20DE from the factory. This made me reflect back on the intense amount of custom wiring I had to do, during the GA16DE swap in to my B12. it was much more work than the typical engine swap. Now I know what Hybrid DET and BoostBoy have known for quite some time. ;)

***** Gentlemen, thanks for the compliments! :) AVERAGE, it would indeed, be easier to put in an SR20 at this point, because alot of the wiring would already be done. I have actually thought of that, but what to do for an SR20 4WD trans? I know of a guy from NYC, that has not one, but two SR20 4WD five speed trans/transfer case setups. They came with two SR20DET's he imported. He has no use for them, he only wanted the engines. I have considered the possibilities, but I am not ready to do something like that just yet. Hmm......maybe someday. :p

most of the FWD are actually AWD Sr20DET.... :) you would probably get one of those if you went throu an importer !! :)

nice though : B12 4WD, SR20DET ... that would make an Sentra SSS ?? or a Sentra GTI-R :)

Now if you could just do all that into a sedan body.. ;>
***** I like the wagon though, because I can fit six extra studded tires in the back, along with a floor jack, and other gear. Then it's time to head out on the frozen lake! :D
