Nissan Skyline R32 - Clutch Master Cylinder and Clutch Slave Cylinder USDM Compatibility

Nissan Skyline R32 - Clutch Master and Clutch Slave Compatibility

Wondering what Clutch Master Cylinder and Clutch Slave Cylinder are cross compatible with USDM parts for your Nissan Skyline R32 GTR or GTS-T? Look no further.

Nissan Skyline R32 GTS-T Clutch Slave

The clutch slave for the GTS-T is identical to the clutch slave in the 240SX S13. You can purchase them on Amazon here or on eBay here. There are multiple interchangeable part numbers, but if you plan to go to a parts store, just be sure to use a year of S13, not S14. 1992 works.

Nissan Skyline R32 GTR Clutch Slave

Unfortunately the Nissan Skyline R32 GTR doesn’t have a direct interchange USDM compatible clutch slave cylinder. However, the early R32 GTR are the same as the R33 RB25DET clutch slave cylinder, which has a somewhat plentiful aftermarket offering here in the USA. You can buy one on Amazon here, or here, and eBay here.

Be sure to look at your slave cylinder on your transmission to see which one you have. The early transmission is an L shaped cylinder, while the later pull-type transmission of the R32 GTR has a completely straight slave cylinder.

Nissan Skyline R32 GTST Clutch Master Cylinder

The R32 GTST do not have a direct plug-and-play clutch master cylinder in the USA. There is one viable option if you aren’t against bending a hardline, however.

The S13 240SX clutch master cylinder will fit the Nissan Skyline R32 GTST if you bend the clutch hardline that goes into the cylinder. It’s not a drastic change, and there is room for the bend to not kink if done properly, but do so at your own risk. The line in the Skyline cylinder goes into the top of the cylinder, whereas the 240SX S13 goes into the side.

If you want to buy the cylinder, you can purchase it on Amazon here, or eBay here.

If you don’t want to bend the hardline, you might be able to get lucky on eBay finding a used clutch master. New ones are $100~ as of writing this post, but I have seen used ones pop up as low as $30 on eBay.

Nissan Skyline R32 GTR Clutch Master Cylinder

The R32 GTR doesn’t have a USDM Compatible Clutch Master Cylinder. Your only option is to find a used one or aftermarket replacement, which you can find on eBay here for about $100.

How to change the RB20DET spark plugs - R32 Nissan Skyline GTS-T DIY

RB Motoring

Changing the spark plugs in your RB20DET is an easy job if you've ever turned a wrench. You'll need the following tools:

  1. A basic socket set (I've had the same Kobalt set for 10 years. I can return anything that breaks to Lowes, no questions asked, and they even replace missing sockets for the price of shipping and handling.)
  2. Flathead screwdriver
  3. Long 3/8" extension
  4. Hex socket set
  5. Spark Plugs
  6. Spark plug socket
  7. Torque wrench
  8. Anti-seize

All the images below can be expanded by clicking on them. 

The spark plugs in the RB20DET are located under the black plate that says NISSAN. To get to it, we need to remove the crossover pipe. It can be done without removing the crossover pipe, but it makes things awkward and cramped, and removing the pipe takes minutes. 

Start by loosening the clamps labeled above. Both ends of the intake pipe, both ends of the blowoff valve, and one end of the black hose labeled #5 should be loose when you are finished. Flip the #5 hose out of the way. 

The crossover pipe is bolted to the engine with two bolts right above the kink in the crossover pipe (where it says TURBO). Remove those two bolts. There are two more bolts that hold the vacuum hardlines to the crossover pipe. We labeled one in the image above, follow the lines toward the intake plenum to find the other. Once you remove the bolts, you can remove the crossover pipe and attached blowoff valve. 

After the crossover pipe is removed, you'll need to remove the black plate covering the spark plugs, and unplug and unbolt the igniter. Start at the front of the engine and work your way back. Using your hex head driver, loosen the 6 bolts labeled in red #1-6 that lead back to the igniter. There are two more of these located under the igniter plugs (#7 and #8). Unplug the igniter plugs, and then remove the 4 bolts holding the igniter in place (yellow #9-12). Once the igniter is removed, unbolt the last two hex head bolts that hold down the cover plate. Remove the cover plate to reveal the spark plug valley. 

In the spark plug valley you will see the six coil packs mounted to a metal bracket, plugged in to six brown connectors. Unplug the connectors and then unbolt the coilpacks by the 12mm bolts with 4 etched into the top of them. The coilpack bracket is actually two pieces - pull it away from the head to reveal the plugs. Mine was suctioned in there really tightly, so I had to really wiggle and pull on it. If you can't get it out, wrap a flathead screwdriver with a cloth and use it to pry.

With the coilpacks removed you can finally access the plugs. Use your long extension and your spark plug socket, and take each plug out. Before installing your new plugs, apply a small dab of anti-seize to the threads. This will keep them from seizing (as the name implies...) and will also make them easier to remove next time. I put anti-seize on pretty much every threaded surface that goes back in the car - just be sure not to get it on the electrode of the spark plug! While the plugs are out, it would also be a good time to run a compression check. 

When replacing the plugs, torque them to 20 ft/lbs. Put everything back on in opposite order, and start your car up! 

Replacing the RB20DET Mass Airflow Sensor (MAFS) - R32 Skyline GTS-T DIY

How to replace the RB20DET Mass Airflow Sensor (MAFS) - R32 Skyline Tech

It's not super common for the RB20DET MAFS to die, but when it does you'll know it immediately. This Skyline was running perfectly when we took delivery, but once we parked it and tried to start it again it would immediately die. Diagnosing the MAFS won't be the topic of this article, but will be covered in the future. However, the way we found this particular one was by unplugging the Mass Airflow Sensor and the car was back to running again, albeit with a high idle. 


Getting the sensor out of the car

This is really easy if you have an aftermarket pod air filter, but in this case the car is 100% stock. Still, getting to it is relatively easy but takes some small hands. I don't have small hands. 


The MAF sensor is circled in green, and the 5 clips holding it in are pointed to with the red arrows. 

  1. Jack up the car and put it on jack stands. You can skip this step if you want but trust me, your back will thank you. You don't have to bend over as far and it will also be easier to climb under the car when you inevitably drop your tools. 
  2. Unplug the plug circled in green. 
  3. This is the only "hard" part of the entire removal. Below the plug circled in green there will be a single clamp holding the MAF sensor to a silicone coupler. Loosen that clamp. The area around it is extremely tight so getting a flathead screwdriver in there is pretty tough. I was able to lower it in from the top and turn it from the side, and then get the remaining turns with my hands. 
  4. Once the clamp is loosened, unhook the 4 clips on the stock airbox. There are red arrows pointing to those in the picture above. 
  5. Grab the airbox and pull away from the engine, and out the side. 

You MAF will come out with the top of the airbox, and look like this:


Remove the four 10mm bolts holding the MAFS to the airbox and replace it with your working sensor. 

This is a good time to replace the air filter or remove the entire airbox and replace it with an aftermarket AEM filter.
