R33 RB25DET Clutch Identification

I recently purchased a used Nismo Clutch pack out of an ECR33 Type M.  I got it home and I was very excited but now my excitement is mild concern.  I purchased the clutch out of Japan so all I had to go by was the pictures.  After reviewing lots of photos I decided that the clutch in the photos was the Nismo Sports Clutch kit for the RB25DET.

 

For reference here is a pic of the Nismo RSR21 Flywheel that I thought I was buying.

When I looked at the one I bought it doesn't have any of the nismo markings but I figured it may have been resurfaced at one time so I weighed it on my crappy analog bathroom scale which put it around 16lbs.  The Nismo RSR21 flywheel supposedly weighs just a bit over 15lbs so I was in the right area for weight but again this flywheel has no markings that say nismo.  I looked at some factory flywheels and they dont have the conical dish in the center of the flywheel and they tend to have a bunch of balancing divits where this one only has two which is much more commonly found on the lightweight nismo flywheels.

The clutch disk is the only thing with any part number or markings and it says a four number code that ends with N14 on one side and it has the code RCD-205 on the other side.  I thought this was the RB25DET Nismo Sports clutch but a quick search with the number code RCD-205 only brings up results for the SR20DET.

To further complicate things it also appears that the pressure plate doesn't have any markings on it either.  I think its the Nismo Pressure plate that comes with the Sport Clutch kit but I have no way to confirm this.

Can anyone confirm that these parts are indeed what I think they are or if they are actually factory stock parts for the RB25DET.  I would appreciate it.  Hopefully I have given enough information for someone to make an accurate call.

Thanks in advance,

Alex R.

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
