for my money if you have a genuine 400kw at the wheels GTR you should be looking at nothing less than a triple plate. yes singles and twine can hold the power but to do so they need massive clamping force and simple logic dictates they have much less surface area than a multi-plate. that massive clamping force puts load on the crank and on everything else.

with more surface area in a triple or even quad plate clutch they can be run with near factory levels of clamping as think of one plate at 2000kg and then think of 4 plates at 1000kg. the 4 plates will hold much more power and put much less stress on other components. with more plates (more surface area) they also handle more heat (power/abuse) and also last longer.

so I'd look at an OS Giken triple or quad. NPC also do good multiplate clutches. I also quite like ORC. I've personally used both ORC and OS GIken and happy with both. have not personally owned an NPC but plenty of people I know have and I've driven cars with them.

something like this: http://otomoto.shop033.com/p/4145670/os-giken-r3c-triple-plate-clutch-for-nissan-bnr32-gt-r-after-jan-1993.html

you can check out the os giken catalogues here: http://www.osgiken.co.jp/pdf/catalog_e.html and then chose where you want to buy if from.

ORC triple are like this: http://www.rhdjapan.com/orc-1000f-triple-plate-metal-clutch-kit-nissan-push-type-57305

Nismo coppermix twin plate. Those who have driven a car with one in them will understand.

+1 Yours has held 400rwkw now for how long? :)

Mine is taken huge 7300-7500rpm launches on Drag Radials @ 380rwkw for 1.6-1.5 60ft times, without issue as well and no sign of dying.

Hell Lee wah was running a Jim Berry custom single plate, and the car was making 440-600rwkw in various forms over 4 years without issue as well. His clutch was similar stock feel/weight as are the Nismo Coppermix Twins

IMO no need to get a triple, they just cost more and are a pain in the ass to use, cost more to rebuild etc.

No matter what clutch you use, if you cannot drive and ride the ass out of it - you'll make mince meat of the plates.

Well its been in the car since 2005. DECA it did 40 7500 - 8000 RPM launches? Hillclimbs, drags and general street abuse. Has NEVER slipped or had 'PMS'. If you bog a launch just dial up more revs a few seconds later and go again. Have driven N1GTR's OS triple plate. Hated it. Even he is going back to a Nismo C spec. I think that there says something.

      V37 Radiator removal

      OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.

      OK, now we are ready to get started. You need to remove the air boxes on each side for clearance. The cover is straightforward, undo the clips on the top and lift the front cover out of the rest of the housing. If it is tight you can remove the air filters first. The rear section of the airbox is trickier. On each side you need to remove the Air flow meter wiring which is held to the airbox with a clip; you need to get behind the clip on 2 sides if you want to remove it without breaking it - unclip the harder side and pull on the clip with medium force, then unclip the easier side and it should pop out The airbox is held onto the intake hose with a spring clamp; you need to get a flat bladed screwdriver behind the spring on both sides and pop them outwards. When you have got them in the right unclipped place they will stay there and the airbox slips out pretty freely. Put a rag in the intake to prevent anything getting dropped in there, and also to prevent you seeing that the turbo seal is leaking oil (as they do). Then. The top of the radiator is held by a steel plate, it is secured by 2x10mm and 2x12mm headed bolts . Remove them and remove the plate Also grab the bushings that hold the radiator to the plate on each side so they are not lost!

      Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.

      Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
