I got to ask, how does the LSA fit? I have a built LQ4 with long tube headers and want to go super charger but dont want to spend the $7-10K on a Magnuson super charger (could go with a corvette pro charger but that would screw up my AC system as it would push my compressor into my engine mounts). My understanding was the LSA wouldnt fit under the hood.

@Zetsaz Maybe its just a slight design change but mine does not have that problem. That being said, I could add a diverter down the center of it to "split" the air around the center of the vent.

It's very even with the side vents. I did this to get some more air on my hands during cold mornings.

Hey everyone. I developed and 3d printed an adapter to go from the vintage air mini gen II tube to the center vent on the 280z and figured others might want to utilize it as well. I'm figuring $20 and it's shipped to your door (U.S., I don't know about international shipping). for mine I mounted it in a carbon fiber center section so I also can include the stands to offset the air vent and a cut template to utilize.

So I swapped in a OBX Lsd a few years ago and it has sense been a little louder so I decided to disassemble everything, clean it up and check clearances. In opening up the diff there was a lot of metal in the oil from the OBX unit (every tooth has some kind of minor damage) which I'm not to concerned about but looking at my carrier bearings I wanted to see what yall thought. Running my figer nail over everything there is little to no groves (the case feels like they are factory machined a little rougher) and there is no distortion on the bearings or bearing races. They do however look like they were spinning in the case. I put the race back in the diff and it almost "snaps" into place (very tight, definitely an interference fit). As I don't remember what they looked like the first time I rebuilt it I just wanted to get some opinions before putting it back together. P.s. all bearings are still O.E. with about 200k miles (20 of which was with an LS).

So this is the finished product if anyone else is interested. It is made out TPU which is very flexible (and hard to print). I have used TPU to create plugs for my floors, wiring grommets and other such.

Ok, so i think i have a working prototype for you to try out. I did a stepped lip on the side that buts up against the brake actuator and then did a minor fillet on the side that goes against the car. The inside diameter of the bushing is 28mm instead of 28.5 just to give it a tight seal against the metal "cup that it fits over. I just printed one off and will make a second one that is a little longer (21mm instead of 17 because i figure with the stepped lip it will slip up the shaft that it is sealing against). Again, i do not know how TPU filament is going handle some of the road debris and grease but it does handle heat just fine. I have made all the grommets for my engine bay out of this stuff and it still looks new after two years. If you want me to ship these to you, send me an address in a private message.

@foosman below is what I came up with based on what you gave me. based on the design of the Datsun I am assuming that this part is a seal used to keep out road grim and such (if that is the case, I would change up some of it to prevent water intrusion). With that in mind, the dimensions of that which it seals up against would be just as important if not more. I have TPU filament which is a Composed of polyurethane and rubber but Im not sure how well it would hold up under a vehicle.

Forgive the dust, cutting carbon fiber is very messy. Here is the finished product installed. After about 3 hours of dry time for the epoxy, it took all of 5 minutes to install. It was mounted with a pair of 5mm stainless steel button head screws that I polished to match my existing hardware. my set up is unique and very different than other peoples but I couldn't find a vent to use that I liked for the center area.

I dont know what everyone else is doing about the transition from the vintage AC 2.5in hose to the Datsun 280z center vent but below is what I have come up with. If I am not mistaken the original dash vent just butts up against the original AC housing and there is no tubing. I designed this adapter to be glued to the back of the dash vent which would allow the 2.5in hose to plug into the backside. my set up will be installed into a custom carbon fiber dash insert. This allows me to mount the vent, new LED lights, my vintage AC controls, and potentially another gauge over the vent (I'm looking at a digital fuel pressure gauge). There is also a little overlap from my double din radio. Ill post more pictures once the glue dries and I get it installed. Let me know what yall think

I installed mine on the driver side kick panel and then installed my ls ecu on the passenger kick panel.

What do yall think of my new 3D Printed gauge mount?

No they did not.

If you want to get me dimensions, I can 3D print whatever you would like and sent it to you for the cost of postage. Wont take but 20 minutes to print I'm sure.

I have a set of chromoly stub shafts on my 77 2+2 280z. I am having a lot of problems with the wheel studs not seating/cutting into their holes though. I have tried both ARP and autozone stock ones but every time, the knurl "flattens" out and doesn't bite into the stub shaft. This in turn allows the wheel stud to turn. I have just installed another set with red locktite and am hoping that will do the trick but am not holding my breath. The only other thing I can think of would be to put a little tack weld on the backside to keep them from spinning. Am I the only one with this problem?

Trying to figure out if this is an lsd or just a 4 pinion. Seller says it's out of a zx so I'm guessing it's just a 4 pinion but hope he just doesn't know. I have only seen the inside of a 2 pinion diff.

I am looking for a hi-low beam headlight selector switch. I do not Need the whole assembly, just the switch. I have a 280z but I think they are all the same.

The original connectors are actually very good. I had good luck reusing them and then bought extras and connectors from Amazon for less than $20, they are actually very common connectors (the only common part on the datsun).

I went back and looked. The only O-rings I bought at the time was the Dorman O-ring kit of like 10 different sizes. I assume I matched up the sizes as close as I could get. I know that's probably not what you wanted to hear but that's all I can think of. Make sure its the epdm type rubber as the other stuff will melt away.

Did you have to trim the back (rear) of the front fenders? I'm rubbing my 11in wide rims with 275/50r15s on the rear of the fender (trimmed the front just like you did)

If I'm not mistaken I went to napa with the seals in hand and found some that fit tight. I would suspect you could also order replacements from McMaster that would work perfectly. I will look back through my notes on this.

looks good. I really like that double exhaust outlet and most peoples exhaust area is not in the best of shapes so this option would really clean it up.

I bought the stuff below and after cutting my stuff apart from the rubber (it practically fell off) I glued it on with a plastic epoxy. It is thin enough I was able to glue two side by side to ensure there was a very tight seal.

Well if you are looking for a complete rebuild kit... If you need replacement seals, this is perfect. Everything is different except the seals. I was able to replace all mine and get a good working master cylinder. If you are interested, see the part numbers below. Engine is together and is in. everything is plugging in nicely. I have to finish plugging in the exhaust, install the fuel tank, and finish the cooling system. almost there!!!

That's not bad at all. I chopped up mine and threw a 2002 camaro fuel tank in it. Even if I kept the spare tire I doubt I would have had the guts to use it.
