The short answer is no—no factory Honda Civic model shipped with a K24 engine. The 2.4-liter K-series is used in several other Honda/Acura models, and some enthusiasts swap a K24 into a Civic for extra power and torque.
What follows explains why the K24 isn’t a stock Civic option, which models do use the 2.4-liter K-series, and what a typical Civic-K24 swap involves for performance-minded buyers.
Where the K24 engine fits in Honda's lineup
The K24 family is a 2.4-liter engine platform Honda/Acura employed across multiple models since the early 2000s. It did not appear in the Civic as a factory option. The most common factory applications for the K24-family powerplants include the Acura TSX, Honda CR-V, and Honda Element, as well as certain variants of the Accord. For Civic enthusiasts, that means a K24 swap is a popular aftermarket route rather than a built-in Civic offering.
Below are the main Honda/Acura models that use a 2.4-liter K-series engine.
- Acura TSX — 2.4L i-VTEC (K24 family; various subvariants over production years)
- Honda CR-V — 2.4L (K-series family; early to mid-2000s models)
- Honda Element — 2.4L (K-series family; shared components with other 2.4L models)
- Honda Accord — 2.4L variants in certain markets and years (K-series family)
In practice, while these models used the K24, the Civic did not receive this engine from the factory. The result is a strong aftermarket interest in K24 swaps for Civic builds.
Civic K-series swap basics
For owners who pursue a 2.4L swap, the process typically involves sourcing a complete K24-based donor engine (often from an TSX or CR-V), along with matching transmission, ECU, and wiring harness. Other common considerations include engine mounts, radiator and cooling upgrades, fuel system compatibility, exhaust routing, and a compatible ECU tune to balance power and reliability. Safety, emissions compliance, and local regulations should also guide the project.
Swaps can vary in complexity depending on the donor engine variant, the Civic generation, and whether you aim for a streetable daily driver or a track-focused build. Prospective swap owners should plan for additional improvements such as upgraded intake, intercooler or exhaust (if turbocharging), and a robust drivetrain to handle the increased torque.
Additional considerations for buyers and builders
Beyond the mechanical work, buyers should consider insurance, registration rules for a non-original engine, and potential resale impact. While a K24 Civic swap can deliver noticeable performance gains, it also increases maintenance complexity and potential reliability questions if not done with high-quality parts and professional tuning.
For most Civics, evaluating the total cost of the swap versus pursuing a Civic with a built-in performance option (such as models with proven powertrains or turbocharged variants) is essential. In any case, a K24 swap remains a specialized project rather than a factory option.
Summary
No current Honda Civic model ships with a K24 engine from the factory. The 2.4-liter K-series engines power models like the Acura TSX, CR-V, and Element, and they are a popular swap choice for Civic owners seeking more displacement and torque. A K24 swap into a Civic is feasible but requires careful planning, parts compatibility, and professional tuning to achieve reliable, road-ready performance.
