Lightened flywheel advice please - VX C20XE

Hi all,

Having pulled my engine and gearbox from my car, I figured it would be sensible to replace the clutch.

I have discovered I have the 'pot' flywheel type and it has been suggested that I replace it with the much lighter 'flat' type, to reduce inertia, which I want to do. So not exactly fitting a lightened flywheel as such but just replace with the OEM standard flat type which is lighter

Questions are:

1. is it sensible to stick with the regular flat flywheel or look for an even lighter one? If so, can anyone recommend one?

2. Will I need to change my clutch cover as well?  My clutch cover is very flat but I have seen other versions much deeper - which I am assuming is needed to fill the void created by the flat flywheel type.

3. Should I fit new flywheel bolts?

4. Should I replace anything else such as the  CRB?

Thanks,

David

As well as Paul Exon, I'd speak with SBD motorsport and QED motorsport re flywheel and clutch options.

If it uses the ford clutch arm / fork check for cracks. On mine (k series) the metal at the tip where the cable attaches was very thin and had cracked. I understand they are back in production.

You can buy a light steel "pot" type flywheel, if i am correct the pressure plate is flat and thus less prone to cracks. I bought it from an engine specialist in Holland.

Thanks everyone. 

I spoke to Phil and Road and Race and he recommended standard VX flat flywheel and the helix organic clutch and heavy duty cover, so that’s what I’m going for. 

Thanks,

David
