What is the difference in a series 2 supercharged and a series 3 supercharged 3.8, series 2 was in the 97-03 grand prixs and the series 3 3.8 was out of an 05 or later grand prix. I do not know the difference in either motors and would rrally like some help. Thanks!

04+ GPs got the S3. Not many differences. A different blower, bigger intake valves, electronic throttle body, and a returnless fuel system come to mind right now.

I believe the rods were different materials as well in the later motors.

L67 put out 240 HP and L32 put out 260 HP.
