Here's the note I put on the home page for Importing Japanese Sports Cars into Australia

I originally set up a page to help people decide on how to buy a Japanese import, based around my experience importing a 1989 R32 Nissan Skyline GTR. Now I'm gathering some facts and opinions that may be useful. For instance, I'm trying to get together a list of Oxygen Sensors for all Nissan imports, and identifying generic parts that can be bought from your local spare parts shop. Note: It's up to you to check that they are suitable. I'm just gathering opinions from the web and, as you know, practically everyone on the web is an expert, but many have trouble doing even basic research before going into print. And Google never forgets....

Here is a table of various models of Nissan imports, and the Nissan part numbers for their oxygen sensors. Some sensors also have alternative Nissan part numbers. The information came from an old copy of the Nissan FAST software, but I only have the data for the oxygen sensors, so please don't ask me about any parts except the sensors.

I have also listed part numbers from other suppliers that MIGHT work as alternatives. I have had a lot of support from the NTK technical staff here in Australia, so I am more confident about the NTK information.

Some people have emailed updates, so in January 2008 I finally got around to updating the table again. Come on guys. Send more info. The table is still pretty empty, and I'll update the table quicker now I've got some other stuff out of the way.

Oxygen sensors are also known as Lambda sensors or O2 sensors.

Most models have a single sensor (for the single turbo), but the GTR has two, a front and a back sensor.

Alexia Dupond from France wrote a really good article on changing the Oxygen Sensors on an R33 / R34 GTR. A link is at the bottom of the page.

In July 2010 Lance sent me some updated information, which I've added. Lance also pointed out that I had the front and rear R32 GTR sensors in the wrong order. I can't check any more because my GTR was written off, so I'll take his word for it. I do remember that mine were not in the same order as the manual - but that might have been the previous owner connecting them up incorrectly.

Trivia notes

For NTK Oxygen sensors (see source: NTK Parts breakdown)
the first letter refer to the type of sensor - O = Oxygen.
the second letter refers to the technology the sensor is based on
  - T = Titania and Z = Zirconia. The two different technologies are not compatible.
the third letter "A" or "D" refers to the thread size
  "A" = 18 mm thread (needs a 22 mm socket)
  "D" = 12 mm thread (needs a 17 mm socket)
the set of numbers (or characters) before the dash identify the Sensor (body) construction number
the string of characters after the dash have a character for the Customer Code followed by the Series Number.
So it looks to me as though the R32 GTR is the only Skyline with Titania sensors.
The sensor itself will have a three character code (like D2F) on the sensor and another code on the nut. The code on the nut is the batch number and is not much use to you. The code on the sensor is the important one. It is the sensor (body) construction number.

With Titania plugs:
Black is Reference (Out)
Red is Reference (In) and Heater (+)
White is Heater (-)
Output is 0 to 1 volts.

With Zirconia plugs:
Black is Signal (Out)
White is Heater
White is Heater
Output is 0.1 to 0.9 volts.

Note 1: I had listed the R33 GTR (and 260RS Stagea) sensors as Titania. Apologies for any confusion. Simon from Skylines Australia sorted it all out and gave me the correct information. His old parts were: Front - Bosch p/n A24-A21 140 95250; lead length was 330mm; Zirconia (2 white, one black wire); Square type connector (3 pins. 1 on top row, 2 on second row). Rear - Bosch p/n A24-A21 141 95260; lead length was 380mm; Zirconia (2W & 1 B wires); Rectangular connector (3 pins). He bought the NTK parts listed in the table above. Thanks for the feedback Simon.
Also, you'll see that the sensor Simon identified is the same one used for the N15 etc. They should be easy to get. If you need a longer lead, NTK have a sensor with the same plug and a 1820mm lead which may be the same sensor. It's part number OZA446-E27, and it is fitted to the 300ZX. If anyone finds out if they're interchangable, let me know.

LambdaSensor.com sell Bosch part number 0 258 003 256 for Zirconia based Skylines. It's apparently intended for the Nissan Micra, but fits the Skyline. The NTK equivalent part number is OZA446-E45 (3 wire, type 11 connector, 380mm), so maybe it will work too. They export from the UK to Australia, and can ship a universal Titania sensor for around 70 pounds including shipping.

The Ford EA to EL Falcon uses a sensor which is apparently compatible with some Nissans, although the plug may not be. Its part number is OZA23-D2 so we know it is based on Zirconia. There is an ACA part - ROX207 that apparently also works. If you have fitted one to your Nissan and it works, let me know which engine you have (and its year), whether the cable was long enough, whether the plug was compatible and any comments you have. I'll update the table.

Bosch part number 13385 looks like it might be a contender as an R32 GTR rear O2 sensor replacement. It has a square plug and was fitted to 300ZXs. Its supposed to be compatible with Nissan part number 22690-21P11, which was fitted to the Z31 VG30T engine from April 1987. It's Titania, 17" (430mm) and has the square plug.

Alexis researched O2 sensors for the R34 GTR and found that they were the same as the sensors for the R33 GTR. The original parts all start with A24-A21 14...., and page 519 of a Bosch Document (pdf, 10MB, 519 pages) says that the Bosch universal replacement sensor, part number 0 258 005 726, is a replacement for Nissan parts 22690-24U00 and 22690-24U01 (amongst others).

Wide Band Oxygen Sensors

This page is for parts that can replace factory O2 sensors, and will work with factory controllers. If you want real control though, you should consider Wide Band Oxygen (WBO2) Sensors. An Australian company called Tech-Edge makes world-class WBO2 controllers. I've included their site in the Interesting Sites table below.

Z32 Air flow meters

I have Z32 Air Flow Meters.  I have an orange sticker on each AFM with 22680-30P00 A36-000 N62 printed on it.  A Bosch cross reference document Bosch Document (pdf, 10MB, 519 pages) showed that both Bosch part numbers F00E000202 and 2268063107 are replacements.  I am also told that they are cheaper than the Nissan part. There's a Tutorial on the Skylines Australia forum (see my main page for the link) on how to connect the wiring.

Australian radios and Japanese wiring harnesses

If you fit an Australian radio to your Japanese car, you may need to join up the aerial amplifier wire. The correct connections on mine were really obscure. The radio and the harness had different type plugs that had to be connected - one was a spade, and one was a bullet. I drove around for a couple of months with really bad AM reception until I found the tip on the SAU site. I then re-read the installation instructions and found that I had missed the connection. Now AM reception is fine, and it may have also improved FM. I think the radio was designed to be connected to an amplifier, but I don't have one.

Scratches on your driver or passenger windows

If you have scratches on your driver or passenger side windows that only seem to have appeared since the car arrived from Japan, the problem might be that the compliance shop put the side-intrusion bars in the door, then tightened up the glass support too much. This presses the glass against the pads and any crud in the pad scratches the glass. Also, the white plastic clips can rub against the glass and scratch it. I covered my clips with some of that tape with 'fur' on one side that is used to seal doors in houses, and it seems to work. Fix it before it gets bad. Replacement windows are hard to get. Also, don't think it's just a matter of replacing the tint. On my car the scratches are on the outside, and the tint is on the inside. The only thing that could touch the inside of the glass is a small square pad, and it rarely touches the glass on my GTR (but I cleaned it anyway while I had the door pulled apart putting in new speakers). The scratches may also be because of a buildup of crud on the windows, rubbers and pads while the car was waiting on the docks, or in storage in a long-term carpark. Again, clean them well. I'm told compressed air can be used to reduce the grit if you do not want to replace the pads.
