@siteunseen is kindly hooking me up with 3 injectors, so I should be all set.

@Terrapin Z Curious though, any idea what car those green ones in your pic came out of? They do look to be a bit of a more vivid green than what I've seen. Maybe that's what mine looked like back in the day😅

Well if Site's don't work out these could be another option.

I do not know any specifics on these, They came in a hoard I picked up in OR sometime ago.

As far as the green I think your light ones are just these but faded. Again I am not really sure.

Blue wrote up a thing about injectors on his AtlanticZ web site. He didn't mention ZX NA injectors but I'm sure that they're the same. It's the same injection and basic EFI system.

He also has a good part number for the connectors. I picked up a set of the springed/sprung connectors from a Volvo 240. Get rid of those little wire clips, they're a pain. Any EV1 style injector connector will work. Roam the salvage yard for early 70s and 80s cars. Even some GM cars used them.

Here’s the Bosch Ev1 connector I used. Bought them off Amazon. Gone up a bit in price in the past 3 years.

Zed & Yarb, thanks for the info on the connectors. I might just end up replacing all of mine. Man those Bosch connectors are pricey devils. I'll do some shopping around and see how well I can clean up my existing ones. I've found some 220 grit adhesive back sandpaper, stuck to the end of a popsicle stick is a handy tool for cleaning up those blades inside the connectors👍

Shop Bosch Ev1 connectors. I found some for around $7 each but don’t think they came with the boots. Do yourself a huge favor and change every single one. Knock that critical variable out of the way. You won’t believe how much green corrosion has creeped up the wire.

You've convinced me.🙂 Adding it to my list. I'm especially easily convinced when I've already got it all torn apart and accessible!

I totally feel you on getting a 78 280 to pass smog in CA. Great list. Here's a few recommendations to add based on my own experience:

1. Perform a hot valve adjustment.

2. Consider an additional small fuel filter between the tank and pump just to be safe. Of course, it needs to be changed out every so often.

3. Get new NGK plugs and wires. I like the NGK 4291/ZFR6F-11 V-POWER PREMIUM COPPER SPARK PLUGS.

4. Test your EGR. That was the reason why I failed the first test. Replacement is easy if cleaning doesn't remedy it. Testing procedure is in the FSM.

5. I would just get a new set of fuel injectors. Aside from replacing the rubber collar on a couple of them, my set from MSA have worked just fine. If you can find OEM injectors, even better but I believe those are hard to find.

6. Make sure your AFM is set back to factory. Atlantic Z has a great article on them.

7. I always drive my 78 on the freeway for about 20-30 minutes before the test.

@AndysPlit Great points. Most of those are on my list, minus testing the EGR and the hot valve lash adjustment, so thanks for mentioning that. I'll lookup the procedure. That being said, when I heard this engine run, I was surprised at how quite it was. Hopefully that's still the case when I'm done😄

I'll be sending a full set of OEM injectors out for rebuild shortly, so I'll be able to cross that off the list.

I couldn't help myself this week from making just a couple non-smog related changes. Removed front and rear bumpers, removed power and antenna that was bent beyond repair. Also I'm hoping to pickup a set of 280zx iron cross wheels this week that I plan on restoring. The blue car below is the final inspiration. Love that meaty sidewall and white letter tires. Ideal for performance? Probably not. But visually, I dig it. Oh, and my car will be a bit less shiney 😅

Good luck on the injector rebuilds. I’ve seen a few sets of the ZX iron cross wheels for sale. The ones you have on now are even more common. I have the 15” ZX 82/83 turbo rims. I’ve been looking for a single wheel to replace one of mine, which may take a while. What tire size are you thinking for the wheels you’re looking for?
