On our old forum for Tbird SC's we had data sheets, I haven't seen a single schematic on this forum. The porting and blower info is from other sites and I have no idea why you guys insist on calling 97'-03' superchargers Gen 3 when they are clearly Gen 4. You don't just jump from Gen 3 to 5 a Gen 3 M90 was never offered on GM products.

Are you sure about that??

Taken straight from the web, directly about the buick L67's.

The L67 is the supercharged version of the 3800 Series II L36 and appeared in 1996, one year after the normally aspirated version. It uses the Eaton Generation III M90 supercharger with a 3.8" pulley, a larger throttle body, fuel injectors, cylinder heads, and lower intake manifold than the L36 uses. Both engines share the same engine blocks, but compression is reduced from 9.4:1 in the L36 to 8.5:1 for the L67.
