Alternator clarification....


Recommended Posts

Deckman and I are in a need of a new alternator. After several parts catalog search (auto Atlanta and PET, Pelican) the only part number that i got is 997 603 012 00. But Deckman took his alternator off and the part# is 996.603.012.02. After other research on Ebay different alternator sellers I found out the 996 number is 120 amps and the 997 number is 150 amps... I check with Pelican and PET and the 996# seems to be for Carrera 1999-2004 and the 997 # for turbo manual 2001-2005.... Did they increase the amps ? May be Loren you can clarify? Thanks.

The 996TT (6 speed) can use either:




The MY2003 996 Carrera can use either:




PET does not show amps for each unit so you may need to email Jeff at Sunset Imports and see if he can read the amperage off of each unit he has in stock.

To clarify, the part number JPFLIP listed as what came out of my 2003 996TT is correct. I'm pretty sure that's what shipped with the car when new, and it is a 120 amp unit. When I called a Porsche dealer for a replacement they gave me the part number starting with 997, and that is a 150 amp unit that shipped originally with the 05 996TTS model. Maybe it was a part change they thought all previous 996TT's should have.
