13-11-2005 - The 'new' head came by post. It's a 12G295 and in the center of the picture. On the left, there's a CAM4180 (normal 998 head) and on the right a 12G940 (normal 1275 head). The one in the center is the one as was originally fitted to Mini Coopers with the 998 engine. It's getting rare and is almost perfect for this turbo conversion. This head has better flow than the original one and fits the engine better than the 12G940 (avoiding hot-spots). The larger compression chamber makes getting the compression ratio down easier.
