sin embargo ningun distribuidor se moja....solo sabemos que los precios aumentan cuanto mas viejo es el vehiculo, en este caso el embrague 4.3 es mas caro que el motor 4.7, pero nadie habla de si el embrague es compatible, que se instala 4.7 en 4.3..., a ver si podemos arrojar algo de luz......
ASTON MARTIN VANTAGE COUPE 2006 4.3
ASTON MARTIN VANTAGE COUPE 2008 4.7

.....DEDICADA A LOS PANTALONES ROJOS----VELOCITY .. . .

Not sure I am translating your question properly. That said, the older 4.3 clutch assembly cost more because the flywheel is different. AFAIK the 4.3 flywheel is heavier.

si es cierto lo que dices entonces todos pondriamos el 4.3 hasta en los motores 4.7,..EL DISCO 4.3 ES IGUAL QUE EL DISCO 4.7 ..Y REALMENTE DEBE VALORAR, IGUAL....si solo buscamos diferencias puede haber algo en el diafragma.... pero los vendedores son los que lo saben, y luego los que lo montan, porque tienen los dos, para comparar...

I believe the 4.3 flywheel is heavier to compensate for the 4.3 having less torque that the 4.7 engine.
I believe you can use the 4.7 clutch assembly in the 4.3. I doubt if you would notice the difference.

But aren’t we always looking for a lighter flywheel so the engine revs faster? I know that is the case on the BMW M42 engine swapped into my 2002. So then we should all be using the 4.7 flywheel or something even lighter no?

Entonces que os parece:
1.- el disco de embrague 4.7, solo valido para 4.3, diafragma no
2.- en el motor 4.3 podemos montar todo el conjunto volante, plato disco y diafragma 4.7
3.- nothing can be done from the clutch 4.7 to 4.3
4.- Podemos montar fácilmente el disco de embrague y diafragma 4.7 en motores 4.3 y seguir usando el volante motor 4.3

Because of the slightly less torque, it’s easier to launch the car if the flywheel is heavier..

Once the car is launched, a lighter flywheel helps the engine rev faster.

It’s all a trade off as far as Aston Martin is concerned..
