The Ecotec engine is a DOHC4-valve design that uses a lost foam cast aluminum head and block. It is designed for displacements ranging from 1.8 to 2.4 litres. It was developed in 1994 by a consortium including GM in Michigan, Saab in Sweden, and Lotus Engineering of the United Kingdom. It features aluminium pistons, cast iron cylinder liners, and twin balance shafts.
Stage 2
GM’s Performance Division and Powertrain teams have developed GM Stage One and Stage Two performance upgrade kits for the LSJ 2.0 L Ecotec engine. This engine still maintains full 50-state emissions and CARB Executive Order certification. Stage Two upgrades will increase horsepower by an average of twenty-six horsepower.
Stage 3
Many people have a misconception about stage 3 of the LSJ engine. Most owners don’t realize that the LSJ is actually a very powerful motor and can produce up to 450 horsepower without any external modifications. There are fewer LSJs on the road, and even fewer that are supercharged out of the factory. The reason for this is that many SS/SC owners didn’t know how to do the necessary modifications. Besides, the stage 3 cobalt is not a real one. It’s just a misrepresentation.
Stage 4
Intensity stage 4 of the LSJ engine is a high-performance kit that has been responsible for blowing up many cars. This kit was created by GM’s Powertrain team and uses parts from different manufacturers. Using these parts, you can increase horsepower by 36 hp and torque by 218 lb-ft at 5,400 rpm.
Stage 5
The LSJ engine is a fantastic motor and has the ability to push over 450 horsepower without any modifications. Unfortunately, fewer LSJs are being driven around today because not many were supercharged from the factory. In addition, a large amount of SS/SC owners were not aware of the proper modifications, and their cars were not getting as much power as they deserved. If you’re thinking of adding more power to your car, don’t be fooled by the stage 3 cobalt. The LSJ engine was built to make more power, not kill it off.
Stage 6
The LSJ is a very powerful engine that can push up to 450 hp with no internal modifications. However, there aren’t many LSJs on the road today and very few are supercharged from the factory. There are also many SS/SC owners who didn’t know how to modify their LSJs. They thought a stage 3 cobalt would help them achieve 450 hp but they were wrong.
Stage 7
The LSJ engine is a powerful engine that can push up to 450 horsepower without any internal modification. The number of LSJs on the road today is limited and very few are supercharged out of the factory. Unfortunately, many owners of these cars did not do the modifications correctly and ended up with a subpar engine. The common misconception is that you have to add a supercharger to your car in order to make it run faster. However, this is not the case and most owners aren’t even aware of the fact that their car is capable of such a high power output without a supercharger.
Stage 8
The LSJ engine is a supercharged version of the LK9 Ecotec 2.0 L engine. It features a Roots-type Eaton supercharger and an air-to-liquid intercooler. LSJs produce around 205 hp at 5600 rpm and 200 ftlb (271 Nm) of torque at 4400 rpm. The engine was produced until 2007 and is now discontinued.
Stage 9
The LSJ is a supercharged version of the LK9 Ecotec 2.0 L engine. It uses a Roots-type Eaton supercharger and an air-to-liquid intercooler. Most of its components are shared with the LK9. The LSJ is rated at 205 horsepower at 5600 rpm and 200 lb-ft of torque (270 Nm) at 4400 rpm. It was produced for about six years before it was discontinued.
Stage 10
LSJ engine is very powerful motor that can easily push up to 450 horsepower without any internal modification. Unfortunately, there aren’t many LSJs on the road and even fewer that are supercharged from factory. This has led to a lot of SS/SC owners having no idea of what to do. It is a myth that you can make the car supercharged with stage 3 cobalt.
Stage 11
The LSJ engine is a powerful and reliable engine that can push up to 450 hp without internal modifications. The LSJ was a top 10 engine in the Ward’s 10 Best Engines list for 2006, and is also known as the Z22SE in other countries. It was first used in the Saturn LS1 in 2000 and later in the Saturn Ion as the replacement for the S-Series.
