I got my new J-Spec motor installed tonight and it is tight. On the motor when I got it is what appears to be a dual plate OS clutch with a light steelwheel. It appears that a stock mounting clutchplate won't fit it. Almost seems to have a propriotary flywheel with it. Can anyone confirm this? A search on the net rendered little help, other than the fact that it is a pretty expensive clutch. Thanks.

 

more than likely it is a os giken clutch, about 2 grand for the flywheel and clutch combo. the stock stuff will not mount to it, the clutch mostly come as kits over here i.e. non interchangeable only os giken stuff will work with it

 

Lucki Bastard LoL

 

Well, not that lucky I want to take it off and reinstall my Mazdaspeed flywheel, 3 puck metal clutch plate and HD PP that is on my other motor. I like the harder feel of the Mazdaspeed one. Will I have to change front counterweights if I remove the OS clutch?
