Hi,
Porsche uses the basic engine - the
M96 in all Boxsters, Caymans, and 911 Carreras. The last two characters describe which Bosche Motronic version (DME Software) is used. The 2007 Porsche Carerra uses the new
M97/01, an
M96 derivative, the
M97 contains so many newly designed internals as to deserve a new designation according to Porsche. The Carerra GT's V10 is designated the
M80.
The 2.5L Boxster uses the
M96/20 with Bosch M 5.2.2 Motronic.
The 2000-2002 uses the 2.7L
M96/22 and the 3.2 L (S model)
M96/21, both with Bosch ME 7.2 Motronic.
The 2003-2007 uses the 2.7L
M96/22 and the 3.2 L (S model)
M96/24, both with Bosch ME 7.8 Motronic.
Hope this helps...
Happy Motoring!... Jim'99
