So guys, I'm wanting to ditch this heavy flywheel for a lighter item, have been on courtenay's site and seen the lightweight billet ones for £300.

Which gearbox is fitted to the 2.5V6?

Will an F20 or F28 flywheel fit, as retro-fitted to cavalier and vectra 2.5 v6's to save weight and improve acceleration??

Thanks in advance  8-)

You could fit a flywheel from a front wheel drive setup but, get it lightned by a local machine shop or specialist because courtney etc are real rip off merchants. You will also need the front wheel drive friction and pressure plate to as the omega friction plate has no damper springs in it (the dual mass does this) and the pressure plaet is also different.

For info, the 2.5V6 has an R25 gearbox so an F20 is about as close as you will get (F28 was turbo 4 pot) but fortunately the splines are the same on the front and rear wheel drive boxes.

Ok so F20 flywheel will fit if I use the FWD friction and pressure plate?

Yes....flywheel must come from a V6 though.

Sorry I'm getting confused now lol

I have met people who have an F20 flywheel and gearbox fitted to their V6's..

So what you're saying is I cannot fit an F20 flywheel (from 2.0 16v XE) to mine coupled with the F25 box?

I dont know if a flywheel from a 2.0 will fit the V6 crank.....a flywheel from a V6 cav or similar (which were not dual mass) will.....
