flywheels and starters

[PeteC]

Took the plunge and bought a flywheel from Tiger sports cars to fit up to the zetec, had to take the ring gear of the old flywheel to fit onto the new one. Not a problem but I did notice that the ring gear sits in a slightly different place than on the old flywheel, therefore the throw required by the starter may be a little different. This may explain why there are so many different choices for starter motors out there..

Have a good look at the seat for the flywheel mounting bolts as I understand from the Tiger forum that they are not flat and either need machining or washers used to get the head of the bolt to sit tight.

Thanks for that, I will have a good look. I had heard that the flywheel was a bit thinner and that the crank shaft bolts would require shortening or use the bolts from an automatic as they are already shorter.

Presumably there is a limit to how light you can go with flywheels, anybody know what it is?
The Tiger flywheel is now not going to be used but replaced and I don't know how light is too light. I've found companies selling steel (not lightened cast) ranging from 3.2kgs to 6.8kgs.
On my 2.0 Zetec I have a 216mm (8.5") clutch but am happy to change, although it will be mainly a road car with the odd track day thrown in.
Thoughts anybody?
