has anyone ever had to ever replace a complete new flywheel when changing clutch kit or can it be machined? some places told me that you'd have to replace a new flywheel cant machine.

Depends on the condition of your flywheel, if it's in good condition it should be fine, most of the time people will machine it, but if its full damaged you will have to replace it. However if you do take out the flywheel its best to replace the flywheel bolts to new ones

S2000 fly wheels are recommended to not be machined.

yeh thats what i was told too alot of clutch places go honda recomends you replace a new flywheel everytime you replace the clutch. then i thought honda just wants to make a couple extra hundred bucks off yah thats why they would recomend that. but oh well see how it goes anyway when the clutch gets taken out

they always have a valid reason for recommending it not always from a $$ value.

i know afew people who have machined the standard flywheel and theyre still going good (70,000kms & 90,000kms or so)

It's a hardened steel balanced flywheel that has to spin at 9000 revs.

Machining not only reduces or even removes the hardened layer but can upset the balance. For my money (and legs), I'll replace rather than machine.

I also had the same question asked to me at work so I rang the Honda technical department. Honda recommends all flywheels be replaced as what AusS2000 said. NSX and S2000 definately require replacement and evrything else will be a light skim. Anything more than a light skim you will need to replace it.

Don't ask what a light skim is but if you look at the wheel and there are alot of heat marks and such just replace it to be sure it's still safe.

But definately replace it on an S2000. A few hundred bucks for a flywheel is only a small price to pay than repairing the damage it will cost you. If it lets go, worse case it will write off the car.
