Jag XJ220 / 6R4 Forged Pistons
dont know how much these are worth or if they are of any interest to you but i thought id put a link up for anyone interested 8) http://cgi.ebay.co.uk/Jaguar-XJ220-Metro-6R4-Forged-pistons_W0QQitemZ160154740161QQihZ006QQcategoryZ10390QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

They are low compression (no crown on them) pistons only suitable for a large bore (94mm instead of 92mm) turbo engine. ie, unless you have a suitable engine or VERY deep pockets they would make good ashtrays!...

Cheers for the info there Ali :)
