This 3800 weighs only 22 lb (10 kg) more than the all-aluminum High Feature V6 that currently dominates GM's six-cylinder applications, 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.
The CXL Turbo comes equipped with a turbocharged 2.0L direct-injected Ecotec DOHC I4 rated at 220 hp (164 kW) and 258 lb⋅ft (350 N⋅m) of torque, mated to either an Aisin AF40 6-speed automatic or a 6-speed manual transmission, making the Regal Turbo the first Buick model to be offered with a manual transmission since the Buick Skyhawk ended ...
Initially an uneven-firing engine, Buick later redesigned the crankshaft to a "split-pin" configuration to create an "even-firing" version. After it became the 3800 V6 in 1990, the engine gained a reputation as a reliable, powerful, fuel-efficient workhorse that became a mainstay of GM's FWD mid-size and full-size cars. It was discontinued in 2008.
A unique intake manifold that used the 48 mm (1.9 in) twin-bore throttle body from the 5.7L TPI Corvette engine was used on the engine's top end. [9] The turbocharged 4.3 L (262 cu in) was last used in the GMC Typhoon in the 1993 model year. The engine produced 280 hp (209 kW) at 4400 rpm and 360 lb⋅ft (488 N⋅m) of torque at 3600 rpm.
Starting in 1979, a two-barrel intake fitted with a Rochester Varajet carburetor and dual take down exhaust manifold were used in trucks and vans. The "integrated" cylinder head and intake manifold claimed to have resulted in increased low end torque and fuel economy inclusive of a smoother operation, lowering NVH (noise, vibration, and harshness).
Introduced in the MY2012 Holden Commodore SV6 and the MY2012 Chevrolet Camaro LS/LT, it is 20.5 pounds (9.3 kg) lighter than the LLT, thanks to a redesigned cylinder head, integrated exhaust manifold, and composite intake manifold. Other components like the timing chains, fuel injectors, intake valves, and fuel pump have also been updated.
The High Value engine family from General Motors is a group of cam-in-block or overhead valve V6 engines.These engines feature cast iron blocks and aluminum heads, and use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm (3.90 in) bore required offsetting the bores by 1.5 mm (0.059 in) away from the engine center line.
It featured the same multiport fuel injection intake manifolds and throttle body as the LH0, and produced 205 hp (153 kW) at 5200 rpm and 225 lb⋅ft (305 N⋅m) of torque at 2100 rpm. Around 3,700 engines were produced each year. This engine had a block with more nickel content and hardened internals. Applications:
