metalmonkey47 Posted January 30, 2013 Report Share Posted January 30, 2013 Is it possible/feasible to do? Only reason I ask is because I believe my flywheel is warped (all my clutches come off warped regardless of brand and PP combination, and it's not leaking) and it's annoying. I'm killing clutches on this thing. New clutches feel good for about a week before the initial friction zone is gone, and then they grab snappy and only start to feel friction at the top of the pedal. I was looking at aluminum replacement flywheel/clutch combo's and they are wayyyy cheaper and widely available compared to the L20B which is a lot harder to find at a good price.. Just seems like it should work, but maybe I'm under thinking this? Quote Link to comment
schicksal Posted January 30, 2013 Report Share Posted January 30, 2013 Yeah the L6 clutches and flywheels do work on the L20b. You have to use the throw out bearing and collar from that year car you got the clutch from. Like if you get the 240mm clutch from 280zx turbo you need the throw out bearing and collar from that car.

banzai510(hainz) Posted January 30, 2013 Report Share Posted January 30, 2013 sounds like to me your using used cflywheels that need to be turned/machined. importrp.com has cheap Daiken stock clutches.for 620s and Daiken 225mm stage one if you want to break your leg on a stock motor. when first in to my 510 I would get a new clutch once a year. Disc would alwas look good. then One day I put another flywheel on and never had that proplem again. Roadster PP should last over 10years for sure most likely even longer. So more or less I was throwing away good Roadster P/P thinking they were bad. Quote Link to comment
Farmer Joe Posted January 30, 2013 Report Share Posted January 30, 2013 you can use any 6 bolt flywheel... the L/Z/KA have the same flywheel bolt pattern, and the Z and KA ones are plentiful. i had a Z24 flywheel and a 240mm clutch on the L20. its on the a Z24 again now. i preferred the bigger clutch. gripped better, even for just a stock clutch kit. might even be cheaper.

DanielC Posted January 30, 2013 Report Share Posted January 30, 2013 I recently got a 280 ZX 240 MM flywheel, pressure plate, to bearing, collar, and fork, and disk. I plan on having the flywheel turned to clean up the surface. I would like to get a new disk, not a whole clutch kit. I called the friendly local Nissan dealer and a clutch disk is NLA. Will a Z or a KA 240 MM disk work? Quote Link to comment
datzenmike Posted January 30, 2013 Report Share Posted January 30, 2013 The L6 wheels are lighter than the L4 ones as a rule. 29lb vs. 21lb. Quote Link to comment
metalmonkey47 Posted February 21, 2013 Author Report Share Posted February 21, 2013 DERP. So I forgot I posted this until just now. I've been looking at prices and I've found that everyone lists the S130 2+2 flywheel under a separate listing?? Is it any different the the standard L28E-ET flywheel? What's the lightest these can be machined to? The reason I ask is because I want the grippiest thing I can get for it, and minimize parasitic loss in the driveline. The motor it's going to be attached to is going to be FAR from stock. Quote Link to comment
banzai510(hainz) Posted February 21, 2013 Report Share Posted February 21, 2013 I believe the 2+2 is a 240 mm flywheel or a differnt strength stronger. Its a heavier car remember the throwout bearing and collor is based on clutch finger height. to make this simple get a 620 225mm set up.if you have a 225mm flywheel the car cars had alot of different set up over the years. key is getting the flywheel machined!!!!!!! you bleedin your clutch system also.? The reason I ask is because I want the grippiest thing I can get for it?????????? whats wrong with a daiken stage 1 from importrp.com or other places. That should be more than enough. http://performance.importrp.com/exedy_clutch/exedy_racing_stage_1_organic_clutch_kit/06805a/i-34392.aspx price usually stops most people from doing this , or just get the stock Daiken as its 450KG I believ which should be good and about 100$ use the above listing to swap or see if part numbers the same between different vehicles Quote Link to comment
datzenmike Posted February 21, 2013 Report Share Posted February 21, 2013 If you get a 240mm you can fit the 300zx turbo clutch to it. Quote Link to comment
metalmonkey47 Posted February 28, 2013 Author Report Share Posted February 28, 2013 Thanks for the help guys, i decided that instead of sourcing the collar etc for the 240mm and everything else, i just ordered the Exedy stage 1 225mm :thumbup: Quote Link to comment
Xnke Posted March 1, 2013 Report Share Posted March 1, 2013 Stock 225mm L24 flywheels are 24lbs, stock 240mm L28ET flywheels are 28lbs, 225mm flywheels can be machined down to 15lbs without exploding but cannot be turned after being machined down that far, and 240mm flywheels can be cut down to 17lbs. Come in under the ring gear at a 35* angle, leave at least a 1/8" radius at the root, and machine the inertia ring flush with the back of the flywheel. Cut the raised lettering down flush, until the as-cast surface is removed. Remove as little material as possible to remove the as-cast finish everywhere except the big inertia ring around the outside. DO NOT DRILL HOLES! You want to remove the material as far from the center of the flywheel as you can get, and when you're done, you MUST ABSOLUTELY have it rebalanced. That said, a stock 225mm KA24DE lightweight flywheel (13lbs) can be had on ebay from CBAutohaus for 113$. I regularly buy from the parent compay of CBAutohaus and they have very good quality clutch components, they are actually the OEM-supplier for the parent companies of Gripforce, F1 racing, Bahnhoff Performance, XTD, ect. Before you condemn them based on being a "shit ebay clutch", know the following: The shitty shit clutch kits that Gripforce, F1, XTD and the like sell on ebay are actually UNDER-RATED! I.E. you buy a 225mm Stock clutch for a KA engine and you get a stock disk with a cheap, low-end pressure plate that doesn't even meet stock spec! Buy the "stage 1" kit and you actually get a stock KA clutch, buy stage 2 and get a HD pressure plate and a stock disk, stage 3 is a 6-puck copper-ceramic with a HD pressure plate, ect. The supplier sells them what they order...then they turn around and sell it as a "performance clutch" when in reality it's just a stock clutch with some spray paint. Honestly, I'd just surface the flywheel you have and run the exedy clutch. Quote Link to comment
metalmonkey47 Posted March 5, 2013 Author Report Share Posted March 5, 2013 Thanks for the machining info XNKE! I did end up getting the stage 1 Exedy, and I'll be having a flywheel machined soon :thumbup: Quote Link to comment
