GM LS Series Engines The GM LS series has become the undisputed king of the import swap scene, and the NSX is no exception. This balance of old-world chassis engineering and new-world displacement is why the NSX swap community remains vibrant and technically sophisticated.
NSX Engine Swap Structural Integrity Check: Ensuring Chassis Strength and Safety
Swaps utilizing the B18, B20, or especially the B16 from a Type R have been common, but the true performance ceiling lies with the C32B from the original 1990s NSX or the C35B from the later models. The cooling system must be redesigned to handle the thermal output of the new powerplant, often requiring larger radiators and custom plumbing.
An LS swap requires more fabrication, including custom motor mounts and transmission adaptation, but the payoff is a massive increase in horsepower and torque, along with access to a vast aftermarket support network for reliability upgrades. This specific procedure involves replacing the original powertrain, typically a Honda K-series or hybrid electric motor, with a different engine, most commonly a larger displacement Honda VTEC unit or a robust GM LS platform.
