 L67 Supercharged
A 3800 Series II L67 Supercharged engine in a 1998 Buick Regal GS.
The L67 is the supercharged version of the Series II L36 and appeared in 1996, one year after the normally-aspirated version. It uses the Eaton Generation 3 M90 supercharger with a 3.8″ pulley, a different 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. Power is up to 240 hp (180 kW) and 280 lb·ft (380 N·m) of torque. Final drive ratios are reduced in most applications, for better fuel economy and more use of the engine’s torque in the low range. The engine is built in Flint, Michigan. The engine was certified LEV in 2001.
