An LS engine swap involves replacing a vehicle’s original engine with a General Motors LS-series engine. The cost of this conversion varies significantly depending on several factors, including the specific LS engine chosen, the vehicle receiving the engine, the parts used (new or used), and whether the work is performed professionally or by the vehicle owner. A basic swap using readily available used parts might cost a few thousand dollars, while a high-performance build with professional installation can easily reach five figures.
Swapping in an LS engine is often motivated by a desire for increased horsepower, torque, and reliability. LS engines are renowned for their relatively compact size, lightweight construction, and potential for significant power gains. This makes them popular choices for a wide range of vehicles, from classic muscle cars to trucks and even import cars. The aftermarket support for LS engines is extensive, providing readily available parts and a wealth of knowledge within the automotive community.
