that is the one I also found. I managed to save the info on my HD in case the site disappeared.

@Captain Obvious let me know if that link works. I have the doc saved on my laptop and just did a drag and drop. I test clicked the link and the doc was put into my downloads folder.

The 2 sets of faulty injectors that I saw on ZCar were used in 1982 or 1983. Nissan made big changes in 1982 eliminating the external dropping resistors and incorporated their function inside the 82-83 ECUs. I too have been looking for other injector options. Ford had some yellow top hi impedance that may work on the pre 82 cars if the dropping resistors are removed. There have been many vehicles that used the EV1 style bosch style injectors including range rover, mercedes. If found a 1974 and a 1975 SL500 at the local junk yard and pulled the injectors from one of them and they flow twice as much as what is in the Datsun. Here is some very useful information that I found out on the web. Injector Information.odt

Hey @Captain Obvious , what kind of injector testing are you planning on doing? I have collected a pretty good pile of them. I have Pink ones from a 300zx, green ones ( at least 2 different colors of green) and I have a set from a 75 Mercedes SL500 that flow like mad! I purchased a couple of Autool CT150 injector machines for cleaning and testing purposes.

Over on another ZCar site we have seen the "no injectors firing after replacing all injectors with new" issue with some of the aftermarket injectors that are on the market today. One interesting this is that the injectors would fire if one or two of the injectors were disconnected. Even some of the Z CAR DEPOT injectors were doing it. Never could narrow down exactly what the issue was/is. Someone that has way more electronic knowledge that I thinks it has to do with the inductance. Here is a link to that post https://www.zcar.com/threads/1983-280zx-with-weird-injector-problem.427586/?post_id=2820006#post-2820006

Great info on the Toyota housings. I just managed to get 2 sets of housings and 2 sets of Auxito Led H4 for 100.00 including delivery! LEDs for my 81 and 83 on the way.

Personally I would start with getting the engine running before you take it apart. That way you have a baseline and know it will run. Disassemble of a non-running engine may get you a non-running engine after you spend $$$$. If it runs before you know it will run after. my 2 (no longer in production) cents worth.

I run manifold as it makes my car run better. I have 3 Oxygen sensors on my 1983. One for the ECU (narrow band) and 2 wide band running 2 different AFR gauges. I wanted to compare the AEM to the Innovative meters. They were pretty close. The reason I did this was because the AEM sensor right out of the box was bad. I spent a week trying to figure out why a 1979 ZX ran really good but the AFR said it was way lean..........bad O2 sensor. My wife purchased the AEM for me for Christmas but I did not get around to installing it for a year......warranty ran out so I purchased the Innovative and purchased a new sensor for the AEM. With both wide bands sensors installed I was showing the engine slightly rich, 14.0. Both showed this. When I crack the throttle, I would get a front fire (lean condition), some call it a backfire thru the AFM. I also have a 1981 that everything is new on that car. All original Nissan parts. I have always used manifold vacuum to the distributor on that car and it runs great. I switched the 83 to manifold vacuum, adjusted the static timing from 10° to 7°, reduced the idle speed and WHAM...no more front fire and the car runs strong. Third car, a 1983 that I sold to someone in the Houston area (Greg). I recently drove back down to Houston to help him with some issues. (replace intake/exhaust gasket, fix some rust in the windshield channel, install a new AC compressor. When I reassembled the engine, I decided to switch the distributor over to manifold vacuum, reset the timing and idle. I talked to Greg about the difference and he was willing to see what it would do. The difference in the cars performance was really amazing. Greg had the car for 1 year so he was familiar with the original configuration performance and he was astonished on how much it changed how the car pulls. Like I posted, swap between the two ports and drive your car to see how it affects YOUR car. Carb cars may react different than EFI cars. I dont have a carb car. Remember that your distributor has to be in good condition. The vacuum advance must work and the mechanical advance must work. It all works together.

I will disagree with CaptainO....sorry. Do some research into ported vacuum vs manifold vacuum for distributors. I totally understand that Datsun has really smart engineers building these cars and engines, but....I run both my 81 and 83 on manifold vacuum with slightly reduced static timing. Cars run fantastic. I agree that the factory attachment was ported vacuum. Try both ways and see how the engine performs. Adjust the engine idle to the proper spec when you switch.

What is the name of the business?

I just shipped a door glass for a 1983 280zx from the US to Switzerland. 22 pounds, mostly packing material. Box was 46x24x6. Shipping cost thru USPS was 188.00 International Priority 10 day. I was quoted 2500.00 by a UPS approved shipping store in my home town. I go on Shippo and Ship Pirate and Paypal shipping and came up with a shipping cost as low as 280.00 thru UPS. Someone is jacking up prices. I went with USPS International Priority. Hopping it gets to Switzerland without being broken. I filled out the forms online at Click-and-Ship US Postal. Super EZ. We will see....................

Yes Advanced Distributors is still in business. Jeff still own the place. I have done business with him for a couple of years now supply some of the parts needed to refurb the Z or ZX distributors. One thing to keep in mind is that the vacuum advance canisters are getting hard to find. I know there is a place in Australia that can rebuild a vac advance can.

The 1979 to 1983 matchbox distributor is a good upgrade.
