The L20 is an engine produced by General Motors for full-size van and pickup vehicles. Displacing 4. It was previously available in the Chevrolet Silverado and GMC Sierrabut has been replaced by the all-new 4.

The Vortec 4. One of the enablers of the 4. The 4. Quiet features built into the engine are complemented by an improved engine cradle and mounting system. These help reduce vibrations transmitted through the chassis and into the passenger compartment. Its deep-skirt design helps maximize strength and minimize vibration. The result for the customer is less engine wear, improved durability and quieter operation.

High-Flow Cylinder Heads and Valvetrain : the 4. The high-performance cylinder heads support great airflow at higher rpm for a broader horsepower band, along with strong, low-rpm torque. E85 Flex-Fuel Capability : E85 is a clean-burning, domestically produced alternative fuel composed of 85 percent ethanol alcohol and 15 percent gasoline.

Ethanol is renewable and produces fewer greenhouse gases in the combustion process. It can be produced from various feed stocks, including corn and wheat stalks, forestry and agricultural waste and even municipal waste. Advanced Electronic Throttle Control : with ETC, there is no mechanical link between the accelerator pedal and the throttle body. A sensor at the pedal measures pedal angle and sends a signal to the engine control module ECMwhich in turn directs an electric motor to open the throttle at the appropriate rate and angle.The LS based small-block engine is the primary V8 used in General Motors ' line of rear-wheel-drive cars and trucks.

Introduced in Januaryit is a "clean sheet" design with only rod bearings, lifters, and bore spacing in common with the longstanding Chevrolet small block V8 that preceded it as the basis for GM small-block V8s.

The basic LS variations use cast iron blocks, while performance editions are all aluminium with cast iron cylinder liners.

Variants of the LT version of the GM small-block have been used since. Most of the credit for this engine family must go to Ed Koerner, GM's Powertrain vice president of engineering operations at the time. The performance improvements in the LS-family V8s over the previous classic small block V8 family are several.

The lower section of the block incorporates deep side skirts, along with 6-bolt cross-bolted main bearing caps. This fully boxes the crankshaft, creating a very strong and rigid structure that has been hot-rodded by enthusiasts to over 1,HP. Although it is the same compact physical size as the classic small block V8, this block can accept a 4-inch stroke as an option in its stock form, due to the cam location being elevated slightly, compared to previous block designs.

Also, the cam bearing journals are larger, to allow for a higher cam-lift profile than was previously possible. The stock aluminum heads can provide a high amount of air-flow, which previously could only be found in aftermarket race-performance heads. The aluminum heads also incorporate steam vents to prevent gas pockets from building up in critical areas, and this is vital in allowing the coolant to manage heat build-up for high-performance applications. Such design features allow for a higher compression ratio with no fear of detonation.

The thermostat has been located at a low position, which eliminates the possibility of a gas pocket preventing the thermostat from properly sensing the heat of the coolant. Previous generations incorporated a coolant passage through the intake manifold to warm the incoming fuel-air mixture in very cold climates.

However, modern fuel-injection techniques eliminate fuel atomization concerns under all conditions, so the LS family uses a dry intake manifold. This removes a common coolant leakage point, and also allows the incoming air to remain as cool as possible for better power production. The architecture of the LS series makes for an extremely strong engine block with the aluminium engines being nearly as strong as the iron generation I and II engines.

The LS engine also used coil-near-plug style ignition to replace the distributor setup of all previous small-block based engines. The cylinder firing order was changed toso that the LS series now corresponds to the firing pattern of other modern V8 engines for example the Ford Modular V8. The first of the Generation IIIs, the LS1 was the progenitor of the new architecture design that would transform the entire V8 line and influence the last of the Big Blocks.

The Generation III 5. The extra horsepower was claimed to come from the intake ram-air effect available in the SS and WS6 models.The L20 is a 4.

GM 4.8L Liter V8 Vortec L20 Engine

IV iron block truck engine. It replaced the LY2 in It was available in GM pickups and vans until It was also known as the Vortec These engines are strong and durable. Many people use them with boost or nitrous. With upgraded internals, the blocks can handle over 1, hp. The L20 4. However, that will thin out the cylinder walls. A smaller bore size will keep the block strong and rigid. These motors are capable of making a lot of horsepower, and respond well to upgrades like turbos, superchargers, high-flow cylinder heads, intake systems, cams, and nitrous oxide.

Check out L20 4. The aftermarket is strong for LS swap engines. Summit Racing has created a series of comprehensive guides for each engine in the LS family, so engine builders and tuners can have a handy reference for their projects.

This guide is specifically about the GM L20 4. The L20 replaced the LY2 in Pingback: L20 4. Your email address will not be published. Your Website.

LS Engines L20 4.The Nissan L series of automobile engines was produced from through in both inline-four and inline-six configurations ranging from 1. This was the engine of the dependable Datsuniconic Datsun Z sports carand debut upscale Nissan Maxima.

These engines are known for their extreme reliability, durability, and parts interchangeability. It is a two-valves per cylinder SOHC non-crossflow engine, with an iron block and an aluminium head. The four-cylinder L series engines were replaced with the Z series and later the CA serieswhile the six-cylinder L series engines were replaced with the VG series and RB series.

The legendary L16 four-cylinder design is derived from the Mercedes-Benz engine Prince Motor Company was licensed to produce copies of in four- and six-cylinder displacements. By the time Prince merged with Nissan in it had altered the design to where it no longer needed licensing. The engine still resembles a Mercedes in many ways, particularly the valvetrain. The six-cylinder L20 rushed into production by Datsun in was designed prior to the Prince merger using the Mercedes overhead cam engine as a model.

The L13 was essentially a de-stroked L The L16 replaced the Prince G When this engine was installed in a Canadian sedan model with manual transmissiontwo sets of points were installed in the distributor and this second set of points was in circuit only in third gear to obtain a different dwell angle.

This engine was equipped with an electronically controlled carburetor. The L16T was basically the same as the L16 but had twin SU carbs, flat top pistons same as ones used in Z and a slightly different head.

The L18 replaced the Prince G in All variants used the same camshaft lobe lift. The L18 was a popular powerplant in many non-USA markets due to its underliters displacement, which made it exempt from many fuel and classification tariffs.

The L18T was basically the same as the L18 but had twin SU carbs, higher compression pistons, and lower volume combustion chambers.

The forged U60 crankshaft also ushered in the use of a six-bolt flywheel boss. The block introduced a taller deck height to accommodate the longer stroke and connecting rods. This specification would also be used later in the Z20 and Z22 engine series. The legendary robustness and nearly square configuration have made this engine a popular choice among tuners for turbocharging.

The engine used a carburetor but switched to fuel injection and round instead of square exhaust ports in some non-USA markets in Carburetors were used in all US L20B applications for both cars and trucks. In the US, the L20B was used in six different model families -A10, S10,and models- making it the most versatile powerplant in the company's US history.

To avoid confusion with the six-cylinder L20, Nissan designated this engine the L20B.The engine—considered an updated version of the LY2—had or casting heads, which are closely related to the LS6. The engine also had flex-fuel capability, Variable Valve Timing VVTand pistons with valve reliefs, offering a compression ratio of 8. Do these engines have a downside?

If you do want to modify the engine, you can take comfort in knowing it responds the same to mods as the others.

There are quite a few parts available that also bolt onto the 5. The problem—if you can call it one—is that the engine starts to sound REALLY good, and owners often find themselves wanting to go faster. At this point, we recommend talking to your chassis dyno tuner and deciding on a computer programmer.

The 4. It also makes it easier to tune with a bigger cam and injectors later on. Before you go, make sure to install a colder thermostat to open up the tuning window.

The first thing to decide is whether you want to maintain VVT. Though uncommon for all-out racing, VVT widens the power band in a street-driven vehicle. More serious cams often require lbs. This makes it hard for the phaser to actuate.

LS based GM small-block engine

In addition, tuning VVT is a little more complex. Generally, 3-bolt cams are more common and just requires the addition of a 3-bolt 4-pole upper gear to convert it over. The price point of a LS3 or LS9 cam is good, but they make the engines pretty soggy up to 5, rpm.

This is due to the intake valve closing IVC point being late and bleeding off a lot of compression down low. What you want is a dedicated truck cam. To maximize torque in the mid-range, manufactures close the intake valve at about 40 degrees at. If the engine is being swapped into a lightweight car with deep gearsconverteretc.

These cams reduce overlap to keep high turbine inlet backpressure from flowing back into the cylinder. Beyond that. The stock rockers are good to lbs. You will want to install a trunnion kit for added reliability. There are a few other parts needed for a L20 cam swap, including an LS2 timing chainLS7 spec liftersLS2 timing chain damperand.

In general, the L20 will see boost or nitrous before any serious head work. Before we get into the power adders, there are a couple things to address:. The L20 injectors were rated at 36 lbs. Luckily, you have many options. As for upgrades, the 1. The shorter 59 lb. Keep in mind, the best injectors are fully characterized, which helps your tuner maximize idle quality, etc.

When running boost, you can use a water-methanol system to supply extra fuel and lower charge air temps.

The factory pump is good to about whp, but many fuel system upgrade options are available.The L20A in-line six engine was based on the design of the L The Nissan Datsun L20A engine features a cast-iron block, a wedge-shaped combustion chamber, aluminum head with overhead camshaft and a fully balanced 7-bearing crankshaft.

The cylinder block is cast in a single unit and features deep skirting. The L20A was an over-square design with 78 mm 3.

The L20A engine has a cast-iron cylinder block, bore is 78 mm 3. The cylinder block, a monoblock specially cast structure, employs the seven bearing support system for quietness and higher durability. The pistons are each fitted with two compression rings and a single oil ring. The crankshaft of L20A engine is made of special forged steel.
