280~Master Posted January 13, 2015 Share #1 Posted January 13, 2015 So after many long years I have upgraded to a L28ET in my 76 running MS3PRO. I am now in need of a clutch for my beast as stock will not hold up to the power. I have looked at after market clutchs and not really impressed with costs. What I did notice is the parts from the L@* are interchangeable with many other nissan engines. The KA, VG30, Z24, L20, SD22, SD25 all seem to have the same basics about them when it comes to the clutch with the size of the surface being different. From what I have read the D21 4x4 truck clutch can hold some HP also.. Well good news is I found a clutch set up that runs under 400 with 18lbs flywheel. setup is 35lbs total. This is a custom flywheel with a 350Z plate and disk stock realese/pilot.. Enjukuracing.com offers a great deal on a custom setup for the L series engines and all of it is OEM parts except the flywheel. A whopping 250mm pressure plate and disk that hold 400HP all day long... Now the poor mans setup....AKA "White Bunny" Flywheel - 240MM 12310-N4256 280ZX 1979-1983 GL, NON GL 6 Cyl 2.8L L28E, L28ET 720 Pickup 1982-1986 DX, GL, ST, STD 4 Cyl 2.0L, 4 Cyl 2.4L Z20, Z24 Hardbody Pickup (1986.5-1994) 1986-1990 Basic, DX, SST, ST, STD 4 Cyl 2.4L Z24 Pathfinder 1987-1990 DX 4 Cyl 2.4L Z24I Clutch Disk - 240MM C010M-24086 280ZX 1980-1983 GL 6 Cyl 2.8L L28ET 300ZX 1984-1989 GL, GLL, SF, SS 6 Cyl 3.0L VG30, VG30T Presure Plate - 240MM - 30210-P9500 280ZX 1980-1983 GL 6 Cyl 2.8L L28ET 300ZX 1984-1987 GL, GLL, SF, SS 6 Cyl 3.0L VG30, VG30T Bearing Release - 30502-21000 200SX 1979-1988 DX/SL, GL, SGL 4 Cyl 1.8L, 4 Cyl 2.0L, 4 Cyl 2.2L, 6 Cyl 3.0L CA18ET, CA20E, VG30E, Z20E, Z22E 240SX 1989-1997 SE, STD 4 Cyl 2.4L KA24D, KA24DE, KA24E 280ZX 1979-1983 GL, NON GL 6 Cyl 2.8L L28E, L28ET 300ZX 1984-1989 GL, GLL, SS 6 Cyl 3.0L VG30T 720 Pickup 1980-1986 DX, GL, ST, STD 4 Cyl 2.0L, 4 Cyl 2.2L, 4 Cyl 2.2L Diesel, 4 Cyl 2.4L, 4 Cyl 2.5L Diesel L20B, SD22, SD25, Z20, Z22, Z24, Z24I Datsun 810 1980-1984 DX, SL 6 Cyl 2.4L, 6 Cyl 2.8L Diesel L24E, LD28 Hardbody Pickup (1986.5-1994) 1986-1994 Basic, DX, GST, SST, ST, STD 4 Cyl 2.4L, 6 Cyl 3.0L KA24E, VG30, VG30E, Z24 Hardbody Pickup (1995-1997) 1995-1997 Long Body SE, Long Body XE, Short Body XE 4 Cyl 2.4L, 6 Cyl 3.0L KA24E, VG30E Pathfinder 1987-1997 DX, SE, ST, XE 4 Cyl 2.4L, 6 Cyl 3.0L, 6 Cyl 3.3L VG30E, VG30I, VG33E, Z24I Van 1987-1990 E, XE 4 Cyl 2.4L Z24I Pilot bushing - 32202-B950A Stock Pilot Bushing - 32202-B9500 Nismo IMPORTANT INFOUse the realse bearing from the year of transmission as advised from others......

EuroDat Posted January 13, 2015 Share #3 Posted January 13, 2015 Be aware when you use a truck flywheel. I don't know if they are all the same, but most Ive seen are 29lbs which will add a lot of rotating weight. Nice for a truck, bad for a sportscar. The 225 and 240mm Z flywheels are both 23 lbs.When you go from the 225mm pressure plate to the 240mm you will increase a couple of lbs as well.A common practice is to have the flywheel lightened proffesionally or use the Fidanza 143281 aluminium flywheel. Finding someone that knows how to lighten flywheels is not as easy as it sounds. Lightened incorrectly it can be very dangerousThe Fidanza will set you back about $300 which isn't really budget, but it is a safe alternative and it will lighten the overall result about 10lbs on the original 225mm setup.It will be intersting to follow your progress.

EuroDat Posted January 13, 2015 Share #4 Posted January 13, 2015 IMPORTANT INFOUse the realse bearing from the year of transmission as advised from others......I think its the release bearing collar thats important. It should match the pressure plate. The pressure plates over the years have different heights. The collar should match the pressure plate.How that works with a 350Z setup? My experience is based on the early stuff up to the 240SX.Be carefull. There is a lot of info out there and the more you read the worse it gets.I ended up going with a 240mm lightened 280ZX 2+2 flywheel, pressure plate, clutch disc and release bearing collar with a FS5W71C tranny from a 300ZX. Project in progress....Chas Link to comment Share on other sites More sharing options...
zKars Posted January 13, 2015 Share #5 Posted January 13, 2015 Re clutch release collar, search on "92mm". This is the total height from flywheel face to place on release collar where the forks touch when you have the right collar. We have an extensive thread that verified this from several users. +/- a couple of mm is okay too. Link to comment Share on other sites More sharing options...
280~Master Posted January 14, 2015 Author Share #6 Posted January 14, 2015 I am going to go with the cometition clutch that uses a flat faced 250MM flywheel.250MM Disk and 250MM plate from a 350Z.Total weight is 35lbs..Will hold the HP I'm after.. and you can not beat the price... http://www.enjukuracing.com/products/competition-clutch-nissan-240sx-white-bunny-upgrade.html Link to comment Share on other sites More sharing options...
