WTB gen V supercharger
- Thread starter ProjectGTP
- Start date
Bone stock flow flow better then the best ported gen3 superchargers.
They came on 04+ gtp's.
The only car they ever put them on? I know a few years later the top dog was the V8. What about the Monte/Impalas and Buicks of that era?
Here you are...
Series II
Introduced in 1995, the Series II is quite a different engine. Although the stroke for the 3.8 L engine remained at 3.4 in (86 mm), and the bore remained at 3.8 in (97 mm), the engine architecture was vastly changed. The deck height is shorter than the Series I, reducing weight and total engine package size. This required that the piston connecting rods be shortened 1 in (25 mm), and the crankshaft was also redesigned. A new intake manifold improved breathing while a redesigned cylinder head featured larger valves and a higher compression ratio. The result was 205 hp (153 kW) and 230 lb·ft (312 N·m), better fuel economy, and 26 lb (12 kg) lighter overall weight (to 392 lb (178 kg)). The 3800 weighs only 22 lb (10.0 kg) more than the High Feature V6, despite being an all cast iron design.
The new intake manifold greatly improved airflow. To meet emissions standards, an EGR tube was placed in the intake manifold to reduce combustion temperatures. This increases fuel mileage by a substantial margin.
The 3800 Series II was on the Ward's 10 Best Engines list for 1995 through 1997.
GM recalled 1.5 million vehicles with this engine on April 14, 2009 due to risk of fire from engine oil leaking under the valve cover gaskets onto hot exhaust manifolds. The fire could spread to the nearby plastic spark plug wire retainers on the valve cover and then to the rest of the engine compartment. GM fitted the affected vehicles with redesigned spark plug wire retainers.[3] These engines were noted for having problems with the plastic upper intake manifold cracking around the EGR passage. The lower intake gaskets and upper intake manifolds were revised, correcting all these issues.

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 III 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 was built in Flint, Michigan. The engine was certified LEV in 2001.
This engine is or was used in the following cars:
[edit] Series III
- 1996–2005 Buick Park Avenue Ultra
- 1997.5–2004 Buick Regal GS / GSX (SLP)
- 1996–1999 Buick Riviera (optional 1996-97, std. 1998-99)
- 2004–2005 Chevrolet Impala SS
- 2004–2005 Chevrolet Monte Carlo SS Supercharged/Intimidator SS
- 1996–1999 Oldsmobile Eighty-Eight LSS (limited)
- 1996–2003 Pontiac Bonneville SSEi
- 1997–2003 Pontiac Grand Prix GTP
- 1996–2004 Holden Commodore VS (series II), VT, VX, VY
The Series III motors include many changes. The upper intake manifold is now aluminum on the naturally aspirated models. Intake ports are mildy improved, 1.83" intake valves (instead of 1.80" as on Series II) and 1.52" exhaust valves were introduced in 2003 engines, just before switching to Series III. Electronic throttle control is added to all versions, as is returnless fuel injection. Stronger powdered metal sinter forged connecting rods are used in 2004+ supercharged, and 2005+ naturally aspirated engines, instead of the cast iron style from Series II engines. Emissions are also reduced. In 2005, it was the first gasoline engine in the industry to attain SULEV (Super Ultra Low Emissions Vehicle).
Also note that Series III engines are the base for any 3800 produced for the 2004 year and up. This means the same block, heads, & connecting rods apply to any remaining Series II engines made after 2004 also. The difference is that Series III engines received the new superchargers (Generation 5 - Eaton m90 - if equipped), intake manifolds, fuel systems, and electronics.
[edit] L26 Naturally Aspirated
The L26 is the Series III version of the 3800. It is still a 3.8 L (231 cu in) design. Compression remains at 9.4:1 as with previous L36's, but the aluminum upper intake (2004+) and stronger connecting rods (2005+) are the primary physical changes. The powdered metal connecting rods were meant to be introduced in 2004 along with the L32's, but the GM plant in Bay City, Michigan that supplies the Flint, Michigan plant could not achieve the desired production dates in time for that engine year.
This engine was used in the following vehicles:
[edit] L32 Supercharged
- 2004–2008 Pontiac Grand Prix
- 2005–2009 Buick LaCrosse
- 2006–2008 Buick Lucerne
The L32 is a supercharged Series III. Introduced in 2004, the main differences between the L67 and the L32 is the L32's electronic throttle control, slightly improved cylinder head design, and updated Eaton supercharger, the Generation 5 M90. Power output is up to 260 HP (194 kW) in the Grand Prix GTP.
Applications:
- 2004–2005 Pontiac Grand Prix GTP
- 2006–2007 Pontiac Grand Prix GT
