New Gt3 crankcase
Change in GT3 crankcase
The upper photo was taken of a GT3 engine delivered from the first batch of GT3's delivered to the USA. Note that it has a 964 casting number and is actually the same casting used in the last air cooled cars.
The lower photo was taken of a GT3 delivered last week. Note has a different crankcase casting with a 996 casting number and the casting has been modified to eliminate features used in the air cooled cars. It also appears to have ribs not in the earlier crankcase. Both pictures are taken from same side of engine.
