Flywheel resurface. How much?

I just picked up this k20a type r flywheel that I will be installing in my 6 speed along with an exedy stage 1 . I know that I will have to resurface it, but what amount should I tell the machine shop. I never had a flywheel resurfaced before since every time I bought a new clutch for any of my cars I always bought a new flywheel at the same time.
Here are the pics:





Thanks in advance

The shop who sees it in person can only tell you that. I just question why deal with used flywheels especially if they already need to be resurfaced. That's just me, have at it.

I had a type-r flywheel in my Si. Before installing it, I paid about $55 to have it resurfaced. I think I paid about $75 for the flywheel itself.

That's about right. A local shop wanted to charge me $50 for resurfacing

That's written on the Exedy website because TSX owners need to switch to a K20 (Type-S/R) flywheel. Since he has the OEM K20 one he doesn't need to use the HF02.

My car is stock, I promise.

Damn you guy are braver than me on used parts. Horrible lesson learned long time ago on flywheel reuse for me.

A local shop here wants to charge me $40. They specialize in Flywheel resurfacing so I think I will be ok. I don't think I would resurface an aftermarket flywheel but since this unit is oem it gives some degree of confidence.
-a2dadamm, I got the k20 exedy stage 1 clutch to go with k20a flywheel.

-harmonichonda, what problems did you experience with resurfacing?

Maybe warping. The flywheel could become out of round and imbalanced. That would be pretty bad on the crankshaft.

Do you know if the flywheel has been machined before? If yes, you should likely toss it.

Machining a flywheel is just like machining rotors. The machine shop should measure it's thickness comparing that to the manufacturers mininimum thickness spec.

If it checks out initially, the shop will start machining it until the surface is perfect. They should take measurements between passes.
If it gets too thin, or is too thin after the machining, the rotor or the flywheel is tossed.

You can resurface and balance a flywheel as long as it's within the factory spec, which is in the service manual.

After years of aftermarket flywheels in my Integra, I'm going to back to a stock ITR...after resurfacing and balancing of course.

There are quite a few places in Orange County that will charge between $40-$60. I used to resurface S13 flywheels all the time when doing swaps for customers.
