Picked up a 78 280z today. PROS & CONS with some Pics.

Good news. I've got 3 light green still in the manifold. Then the front 3 are all brown?

Let me know if you want them. I call pull tomorrow morning. The rest of today will be spent in front of this $825 window unit.ph34r20260629_052358.jpg20260629_052703.jpg20260629_052716.jpg20260629_052720.jpg

@siteunseen Appreciate you digging through your stash! I'll gladly take you up on that generous offer, thank you.👍

One thing I'll ask. In my research online, apparently many injectors carry that A46 part number, but they don't all interchange. I'd specifically need injectors from a 75-78 280Z. The ZX ones have the same A46 number, but they mount differently and won't seat right in my manifold.

Do you happen to know if these came from the 77 280z you mentioned? Thanks again!

No, those are ZX. Let me find my '77 injectors. They're in a coffee can, but OE light green. I'll do it in the morning, it's much too hot for me.

No problem at all, enjoy that AC! 😁

Pretty, pretty, pretty sure that 75 - 83 NA are the same. 300ZX would be different. 280ZX Turbo has a different flow rate. But they're a purple color, not tan or green.

The insulators changed over the years. They look different but they fit the same.

Many of the early EFI engines used these injectors. Even Jaguar used them for a few years.

Zed Head, you're probably right. The more digging I do seems to confirm what your saying, and these injectors were used all over the places, some made by JECS and others by Bosch, but the same at the end of the day. Annoying that they don't have a part number on them that's worth anything.

But I suppose if Siteunseen has a few that he knows came from a 77 280z, I'll try my luck with those first.

One thing I've learned after much wasted money on these cars, I'd rather purchased old, crusty, used OEM parts than shiny new aftermarket parts. More than once I've noticed that a properly cleaned up and maintenanced OEM part will work properly, while the brand new aftermarket part doesn't perform right, or doesn't fit right. Doesn't apply to every aftermarket part, but I really suspect that injectors would fall into that category.

No luck, yet. I spent 30 minutes out there. Found the OE Bosch fuel pump those injectors SHOULD be with but no luck.

I've got another memory of them being with my heat shrink kit that could not find. I'll look more in the morning.

I can send the other 3 tomorrow but those are on an N47 intake that was on a '79 2+2 motor and transmission deal. It had a wide 5 spd I wanted for my 240.

@siteunseen Appreciate you looking! Don't worry about tearing the place apart looking for them, either. If you can't find them, I'll happily try my luck with the first 3 you found. Like Zed mentioned, and as long as they appear to have light green tops, they'll probably be just fine.

I'll get those 3 out unless you want the whole manifold? I can get a box.

It has warming plate,bcdd,tps,throttle body,egr assembly, lots of nissan high pressure fuel hose clamps. All those components I mentioned are assumed bad. It sat in a junkyard for 100 years.20260630_130254.jpg

@siteunseen Appreciate the offer, and I'd take the whole thing if I didn't think shipping would be an arm and a leg, but just the 3 injectors should be all I need and will keep shipping reasonable. If you happen to snip off 1 or 2 of the injector electrical pigtails too, that would be awesome, however many inches of the wire you can easily get. I've got one that's halfway chaffed through the wires. Again, thanks so much☺️

I have two (dark?) green, a few whites, and a brown and black.
