What’s the Difference Between LS1, LS2, and LS3 Injectors?

The physical size of the fuel injector
LS1 fuel injectors are much smaller than LS2 or LS3 fuel injectors. This is due to the fact that the LS1 engine is a smaller engine, and therefore doesn't require as much fuel. LS1 fuel injectors have a longer length compared to other fuel injector types. This is because LS1 engines are larger, making it necessary for the fuel injectors to be longer in order to reach all the engine's cylinders. LS2 fuel injectors are shorter, as they are designed for smaller LS2 engines. The shortest fuel injectors are the LS3 fuel injectors, which are designed for the compact LS3 engine.
Fuel Pressure
The other major difference between fuel injectors is the fuel pressure. LS1 fuel injectors operate at a lower fuel pressure than LS2 or LS3 fuel injectors. This is because the LS1 engine doesn't produce as much power as the LS2 or LS3 engines, and therefore doesn't require as much fuel pressure to operate efficiently.
Spray Pattern
Finally, another difference between fuel injectors is the spray pattern. LS1 fuel injectors have a narrower spray pattern than LS2 or LS3 fuel injectors. This is because the LS1 engine has smaller cylinders, and therefore the fuel injectors need to be able to provide a more focused spray of fuel in order to efficiently fuel the engine.
Fuel Injector Connectors
While fuel injector size is an important consideration, it's not the only one. Another important factor to consider is the type of fuel injector connector. The LS1 fuel injector uses a single-hole O-ring style connector, while the LS2 and LS3 fuel injectors use a multi-hole clip style connector. The advantage of the multi-hole connector is that it provides a more secure connection between the fuel injector and the fuel rail.
