Its normal for a flywheel to have some very slight graze marks on the teeth from the starter motor, but other than that there shouldnt be any chips etc.

one thing to look at and make sure of is that the surface of the flywheel isn't glazed from being dropped at high rpm continuously etc. A few spots of glazing indicate high rpm and shifting and are less of a problem but if the whole thing seems very highly polished and glazed over its not worth your time.

Don't know the part number sorry, but a shop that deals and JDM honda parts should know, just ask around.

To those that suggested aftermarket flywheels ,they are good options aswell.

Granted the JDM honda one isn't actually much cheaper at I decided to buy it for piece of mind. OEM honda parts are great quality and you know there is going to be no issues with them fitting or being overly light for the application.

On an engine with such a long stroke a superlight flywheel could place extra wear on the engine due to the faster revving (just a theory). I found the 4.7kg flywheel with an aftermarket clutch to be more than enough of a performance upgrade and loved what it did for the car.

Don't forget the clutch is a spinning component also and it may be worth changing to an aftermarket one to save some weight aswell.

The oem euro clutch and flywheel comes to 16kg I weighed my aftermarket combination at 9k (both times the box they were in was included).

Hope this helps.
