I bought a light weight flywheel from an rx7 store here in town. the packaging says it is for an fc but the guy who sold it to me said it would fit a fd3, can anyone here confirm this? If I cant get confirmation I will take it back, gonna have my flywheel off in a day or so and will see if it is similar to the new one I bought. If anyone knows it would help out alot (all shops I have called are closed this weekend and I need to find this out asap). Thanks guys-B

 

Which RX-7 store in Raliegh? clean and fast? If not what other RX-7 store is there in Raliegh

just wondering, that's all, I'm not going to speculate on fitment

I remember reading a thread in here a few weeks ago stating that a light-weight flywheel for an FC is close in weight to a stock FD flywheel (close enough not to go with one). I can't find the thread right now, but it should be somewhere.
Unless it is dirt-cheap, I would recommend just a light FD flywheel. I think that the salesperson was trying to get rid of old stock.
just my 1 1/2 cents

 

If it is for a TII it will work on a FD with an FD counterweight.

If it is a 17lb steel flywheel there won't be a lot of difference over the stock 21lb FD flywheel. The 17lb flywheel does have less mass at the outer edges of the flywheel.

If it a 9-11 lb aluminum flywheel then you'll notice a big difference. They are available for TIIs and FDs, again the counter weight is the only difference.

what weight would you reccomend for a t78 with a 6puck race clutch?

The stock flywheel works well for getting the car moving at the drag strip. It also works well for getting the car moving on hilly roads.

Lightweight would be nice for road courses.

Puck clutches tend to tear up the flywheel, running a puck clutch and a lightweight flywheel will wear even quicker. The lighter the flywheel the more you have to slip the clutch to get the car moving.
