The "White Bunny Special" was first created and explained on FreshAlloy by member #18, s14turbose, the "white bunny" being his 98 S14 turbo SE. KA24's come stock with a 225mm clutch surface area, but using parts from other nissans allows you to run a 240mm clutch, which by logic gives you more tractable area for the clutch to grab onto thus reducing the chance of slippage.

We used the flywheel of a 1993 D21 Pickup(4 cylinder model), which is the standard flywheel to use because it carries the same crank bolt pattern as our cranks but is a 240mm flywheel. I believe any year will work, 87 being a common year people use but to play it safe use the 93 because I just installed one and it fit fine. There is also talk of lightened 240mm flywheels, but I have yet to see any that arent custom made.

Now the pressure plate and clutch disc are varied. We used the stock setup of the afor-mentioned 93 D21, but common clutches used are off the 280Z Turbo, the 300ZX Turbo, and the RB series clutches. You can use both aftermarket and stock as long as it is 240mm. But one rumor surrounding this special is the truck and 280Z clutch can hold balls of torque, some saying near 400ft/lbs and they still retain stock pedal feel and longer life than aftermarket clutches. I'm still searching for the answer, but I read it went on Mike Lee's T66 KAT, and it had no problems holding 500rwhp.

One very important point is that the 240mm clutch uses 9bolts to hold the pressure plate onto the flwheel, while your stock uses 6. Be sure to pick some up before you attempt this. Also, you'll have to break the small pin on the crank off to bolt up the flywheel, as it has no slot for it.

and of course here are the comparision pictures:

this is both setups(225mm and 240mm) set beside each other


here are the 240 flywheels, notice the O.D. is the exact same, but the surface area and bolt holes are different



the pressure plates... mmmm that just looks good



and of course the clutch discs



disc and plate



beefy!!!



flywheel bolted up



clutch disc on



pressure plate torqued down




And there you have it, the "White Bunny Special". I'll update this if any new information comes up, and of course details after tyler breaks this setup in and gets to go alittle hard on it. Hope this helps!

And before anyone asks about what the hell is sticking out of my crank, I'll let these pictures do the talking.

That was a fun day/night....the pics turned out really good

If u want to know the prices

I payed
Flywheel - Advanced - $77
Clutch Kit - Nissan - $113 (thats with my sweet hook ups):thumbsup
the normal price is around $150 + shipping

If u do go this way, when u start the car the first with the new clutch their might be a weird grinding/tapping noise when the clutch is pressed in. Dont worry about it just let car run in neutral for a few min. and the noise should go away.

As of now im still babying it, but it feels good:humper

Update: Clutch is broken in and it grabs super hard, definitely well worth it.

2nd gear syncro was out, was never going to rebuild it, but I may use it for spare parts.

how do you use the "system for finding squeeks and rattles" ...really need this one
its a small selector box with 6 different long wired microphones on clips coming out of it. the box has a selector for each mic and a set of headphones. you clip the mics to different sections of the car and drive as you switch between mics. keep repositioning them until you find the source

thanks for the help of 240sxAddict install went very smooth

here a little more pictures and info for people who want to go this route

White bunny test video

after about 2 cans of brake cleaner still had 2more to go

as a result of not running my dust cover this happen. i thought it would help with cooling, but was I wrong..................yup

more size difference pics



tools used to remove old worn pilot bearing for act bearing




putting new setup on

the little bulge that you see at the bottom of the dust cover is what the flywheel will grind down. when the noise has stopped, you will be able to insert your bolts at the bottom of the bell housing. after that, more noise will sound for about 1 minute. after that your all go.

Hey, sorry to bump this old thread back up. I was looking on that site and it doesnt have any specs on that flywheel. It doesnt even say its a light weight flywheel. Does anyone know how much it weighs? Also, how much do the stock d21 flywheels weigh? Thanks in advance for any help!!

dont apologize for bumping the thread, I give rep to you for bumping an old tech thread instead of starting a new one.

we didnt weigh the new flywheel, but would venture to say its weighs the same as the stock one(being the same size and all), just different surface area for the clutch disk. as for the lighter one, I dont know. get in touch with biggamehit

I also have a question. Couldn't you just drill a hole in the flywheel for the little pin instead of breaking it off crankshaft?

do 300zx throwout bearing and pilot work?

or do i need to get the 240sx ones?
I dont know, if you're buying a clutch kit and are trying them let us know. if I had to guess the throwout bearing will should have the right inner diameter, as should the pilot, although I dont know if the pilot will fit nicely in the crank.

I also have a question. Couldn't you just drill a hole in the flywheel for the little pin instead of breaking it off crankshaft?
whats the point? the flywheel is balanced, leave it as is. and the pin wasnt even metal, and it served no purpose in our opinion. it was brittle and just snaped right off without even really trying.

instead of letting the flywheel grind down the bulge on the bottom of the dust cover, couldn't you just take it down w/ a grind wheel?

what throwout bearing do you use? one for the 280zx or the 240sx?
sure why not? i dont recomend letting the flywheel rub anything, hell we didnt even have the dust cover on our install. who cares, its just dust:greddy:

and we used the 240 bearings, but we also bought everything seperate straight from nissan. i dont know what else will work, perhaps I'll search later.
