what's the story about the 964 engine block? As far as I know the GT1-derived engine block, used in GT2/3 and TT, doesn't have any connection with previous models but was developed for racing purposes from scratch. Anybody can confirm this? Not sure on this one...


The GT1 block was a water cooled derivative of the 964 block. Until Porsche switched to a re-designed block last year (changed to remove the last vestiges of support for the air cooled motors such as oil return tube holes) the 996 Turbo/GT2/GT3 blocks actually had a 964 part number.
