If you are considering ways to improve the performance and build quality of the vehicle you are working on, one option is an LS engine swap. Since GM introduced the LS engine in 1997, the world of custom cars has seen lasting change due to the quality of the engine and its ability to improve the function of almost any car that makes the swap.
What Is An LS Engine Swap?
An LS engine swap is the process of changing the current engine of a car with an LS engine created by GM. GM first developed the LS engine in 1997, and its debut revolutionized the world of V8 engines. An LS engine swap is a common tactic for improving the quality and power of a vehicle.
Reasons To Consider An LS Engine Swap
An LS engine swap is not done purely for cosmetics. LS engines offer a range of benefits over most other options. From their power to their cost and the ability to find one that suits almost any need, LS engines have become the most popular swap option, and for good reason. Though they originated in rear-wheel drive Chevrolet vehicles, they are now commonly found swapped into vehicles of all types, from Porsches to Mazdas.
Could Give You More Power
One of the primary draws of an LS engine swap is that it may boost the power of a car. GM created a motor that can push nearly 1000 bhp thanks to a strong engine block and high power output that remains consistent and reliable. LS engines are designed with durability in mind, given that they feature head bolts that are unusually long to decrease the amount of torsion experienced by the cylinder. This configuration also distributes torque evenly, which helps LS engines to function more effectively for a longer time without wear.
They Breathe Really Well
Air directly correlates to speed when it comes to engines; the more air that can be forced through at speed, the greater the amount of power that can be produced. The efficient head design of LS engines are comparable to the engines used by NASCAR when the LS first came out in the late ‘90s. State of the art computational fluid dynamics was behind this engineering feat that makes LS engines popular to this day.
They Are Not Very Expensive
For an engine with such power and durability, LS motors are very affordable. While some higher-end options like the LSX can run $10,000 or more, powerhouse LS1s and even LS3s can fit into almost any car budget with prices starting at just $2,000. LS engines are common in scrap yards, and even those with wear and tear can be revitalized to restore function that is more powerful and efficient than many other engines.
There Are A Wide Variety To Find The Right Fit For Your Car
Every individual’s journey through a car restoration is different, and that means that the LS engine that is right for someone else may not be right for you. LS engines come in a variety of shapes and sizes, from highly accessible LS1s to the 7.4-litre LSX for those aiming for the best of the best.
They Are Lightweight
Part of what makes LS engines so popular even in lightweight cars like the Mazda RX-7 is that the motors themselves are also light. The difference between an aluminum LS1 and a cast iron four-cylinder engine is negligible, and the LS’s pushrod design removes the need for an extremely heavy valvetrain sitting near the top of the engine. This creates high-powered performance with low weight and a sturdy center of gravity.
They Can Last A Long Time
Despite the wide variety of features offered by LS engines, they are simple in design and easy to tune up. A well cared for and regularly maintained LS engine can typically last between 200,000 and 300,000 miles, so even an older model that has seen some use likely still has years of life left.
