rb20/350z flywheel/clutch combo

[kazuma]

Okay I know this topic has been beaten to death already but I just need to ask to make sure before I purchase.

I currently am looking to purchase a rb20 flywheel(250mm) and a 350z clutch kit but I just wanted to make sure can the 350z stock clutch kit(for example the exedy one) handle 350-400 ft/tq? I know with the whitey bunny special you can use a d21 fly wheel and a stage 2 280z-t clutch and handle that no problem but I wasnt sure what is the limit for the 350z/rb20 combo.

Anyways any help you guys can give me would be great.

Thanks.

The limit is whatever the said clutch is rated for. You can find that information online.

Why would you go to all the trouble of getting a rb flywheel then not go for an aftermarket clutch? You can get OEM feel with a much higher max tq rating out of one.

I've also looked into doing this myself.

And why not get the aftermarket clutch? Because the factory 350z clutch is capable of holding 350/350 I'm sure. But Yeah, I guess getting a better one wouldn't hurt.

The only thing I'm still confused about, is what Throwout bearing do you use? I would say the 350z one if I had to guess.

well considering a 350z clutch is meant for a car with about 700-800 pounds more weight than a 240 I'd assume the stock clutch in a ka-t should be able to handle alot more abuse than in a 350z.

regarding the bearing I would guess what ever came with the kit is what you'd have to use.

Not really, the clutch is going to hold the same ammount of TQ as it would in a 350.

see the problem with this is that the white bunny setup can use a stock 280z clutch with a d21 flywheel(which is smaller than a rb20) and can handle gobs and gobs of tq. so why wouldnt a bigger flywheel clutch setup be able to do the same?

Your not going to increase a clutches ability to hold TQ simply by increasing the size of the flywheel. The clutches mating(clamping, whatever) surface itself is only but so big.

One reason the swaps are so desirable is that with the 350 clutch or the 280, you have a larger clamping surface. This means that you dont have to have a racing puck style clutch to hold a lot of TQ as you would with the smaller flywheel/clutch of a 240. All the flywheel swap is doing is allowing you to use said clutch.

Thank you for clearing that up for me

ONE more question, with the bigger flywheel can I also use a 300zx turbo clutch instead of the 350z clutch as it is also 250mm in size.

My SPEC is rated at 450 ft lbs and drives like stock...peddle feel is soft enough for my wife to drive in heavy traffic and had no slippage at 20psi in 3rd, 4th and 5th WOT pulls.

So I can understand if you're saving a bunch of money, but other then that, why would you use a mix matched setup?
