Hi guys, I am selling a complete Fuel injection system from a 1975/76 Z. Please let me know if you're interested and we can talk price. The system is in Oregon. Computer, harness, manifold, air filter box, tank, etc is included. See pics for more details.
 
Message me or reply to this post. Thanks.

Hey Mike, that looks like a 75-77 system.  The intake manifold is the non-webbed N42 intake (very desirable, for some reason).  Nissan started using the webbed intake with the N47 head, I believe, which was mid-1977, apparently.  And there's the three piece fuel rail which is also pre-1978.  1978 used a one piece.  The ECU and AFM numbers would clear things up.  Also, if the ECU and AFM are factory stock or aftermarket (like MSA)  that would be important.

Looks shiny and in good shape.

I always get mixed up with the webbed and non webbed manifolds. Did the N42 have the EGR. I have seen the N47 non webbed with EGR, so it could still be an N47.

Its definately pre August 1977. The fuel pressure regulator gives it away with two inlet and one outlet. The later version only has one inlet. I can just see the last two pins in the AFM 7-pin connector, which means it has the fuel pump switch.

A photo of the ECU sticker would be nice.

75/76 are typically non-webbed and non-egr N42.

The FSM shows 1975 CA cars with EGR.  California got all the good stuff early!

I had a 1978 parts car with a fuel pump contact switch in side.  Looked all original, a survivor.  The 1978 wiring diagram shows the pins and switch and labels them "useless".

I can't find firm documentation but some Googling suggests that it's a 1975 ECU.  The 050 on the AFM looks like 1975 also. It will run the 75-78 systems, just not sure what changes Nissan made along the way.

People like the square port exhaust manifolds also, which 1975 would have.  Is that part of the package?

The bosch ecu came on the very early 1975 model. I think I have a datsun pdf file somewhere with it listed as being replaceable with the later version.

It's a rare ecu and some people like them because it doesn't seem to suffer the lean running condition the later units can develop.

I have four AFM's. One is a pre August 77 with all the pins, two are from ZX's and one was uit of a 78, I think it was March iirc. I must say, I don't have any proof the 78 was an original AFM, but all the later AFM's I have don't have the last two pins in the connector or the plug on the afm. 

That doesn't mean the factory just kept installing the full afm and simply didn't use the switch function until stocks were depleted. You can test it with a multimeter to be sure. Contacts will close when the vane opens.

Can you check the stamp on the top of the manifold. You should see N42 or N47.

If its an N42, with the double inlet FPR, the really early ECU and the 7-pin AFM. Looks like it's from a very early Cal 280z.

Here is a photo of two AFM's I have.

Just noticed, you have a Bosch AFM. Yes, it's all pointing to the very early 75 model. First four months of production I believe.

I made this list in 2013. It's the best I could find at the time when I was looking for a replacement ECU.

I have a look on some back-up drive for the PDF file. It was a scan from a Datsun workshop manual. It did mention something about the Bosch unit was in the first 280Z and if needed could be replaced with the A11-000-051.ECU Part Numbers..JPG

Ok, so who wants to buy it?  I'm cleaning out my storage by August so I need it gone. :)  Looks like I need to adjust the title to say '75 EFI, will do that now.

By the way, thanks for all the help guys!  I thought this car was a '78 but it looks more like it was a '75 or '76.  It's been a LONG time since I got rid of it, so, my memory seriously lapsed here.  I was going to convert mine to fuel injection, but, I don't need that kind of project right now.  I'd most certainly have to replace the tank and fuel pump, which is something I don't want to do right now.  The triple Mikuni's are doing well.

Unfortunately I left Oregon and am now back in Washington.  I'll have to check the manifold when I go back in a month or so...

Here are some pics of the car it came off..  New fuel injectors at the time (probably 10 years ago).  I ended up parting out the car and the fuel injection system was the only parts I still have in storage.

The bumpers say 76 or earlier.  And my 76 has a "square" Datsun on the back hatch, yours has diagonal.  Unless that's a 2+2 thing.  I'm locking in on 1975.

You might get more and move the parts quicker if you spit them up.  AFM, AFM rubber boots, ECU, harness, manifold, even the charcoal canister.  All valuable individually.

I could break up the parts but i think there's probably someone out there who would be interested in the whole package. If you're interested please PM me. Thanks.

There's an old yellow 280Z under a broken down shed on Skyline Blvd.  Still there.  They'd be useful for whoever can break that car free.

  Thanks for the reminder, I remember it well. I'm a bit surprised it's still there, considering it's out in the open next to a busy road. Probably has been a lot of people bugging him or her about it. The owner obviously has an emotional attachment to the car, which is totally understandable.

 As much as I love searching for and finding treasure, I'm becoming one of those old farts who has more projects to complete than time, health and money may allow. I know I'm not alone. However, should anyone need assistance with evaluating Z's or parts in this area, I'd be glad to help. I love looking thru collectors treasures.

I know a guy Mike. He's got a shop with an early 280Z long term project. PM me a price and let me see if I can get the two of you together. I think his customer has a harness problem...
