Ok any 996 GT2 gurus that can decode the different engine types M9670-641 to 644, what are the differences?

It appears that M9670-645 would apply to the 996GT2 Mk2 model with the increased bhp and GT3 style alloys, but it was news that there are potentially four different engines in the 1st gen. Could these be specific to country code.

My UK c16 car has a M9670-642 designation if that helps, I've seen a Canadian c36 VIL sticker showing M9670-643.

the MXX.XX number is the porsche engine code. it groups by basic design so all turbos and GT2 use the same basic engine, Mk1 Gt3 has a different basic engine from the Mk2 GT3 and RS etc.
as for the three digit code, its part of the engine number as is read as follows.......
first digit: engine type. 6 = 6 cyl engine
second digit: engine version
third digit: model year. Y=00, 1=01, 2=02 etc
this is followed by five digits which show the actual number of the engine. the range is covered in your table. ie 00501 >60000

as such there wasnt four different engines for the pre facelift (or whatever you call it) GT2.
