Default How big can I re-bore my block

Hi all,

I have got a spare block now due to Mahle rejecting the cracked pistons.

I want to use bigger pistons. How big can I go?

Cheers
Dave

I would go for the smallest rebore you can get away with. If you do go all out maximum, that renders the block useless if you ever need a rebore...

1mm oversize has given me a 1640cc CVH...

I might go the ZVH way then. Might be safer. I've heard about the bores being bored out on a CVH to 1900cc. Is that right?

Cheers
