Product Details
| Part Number: | ESK4 |
| Brand: | Hasport |
Bring K-Series power to your 7th-generation Civic with the Hasport ESK4 K-Series Engine Swap Mount Kit. Designed specifically for 2001–2005 Honda Civic non-Si models, the ESK4 provides the mounting solution needed to install a Honda/Acura K-Series engine while using a 2003–2007 Accord or 2004–2008 Acura TSX manual transmission.
The ESK4 works with Civic chassis that were originally equipped with either an automatic or manual transmission, making it a versatile foundation for K20 and K24 conversions. Installation requires the use of an Acura RSX or 2002–2005 Civic Si front subframe, replacing the original non-Si Civic subframe to provide the proper drivetrain mounting geometry.
Hasport engineers its swap mounts using sophisticated CAD/CAM design, combining billet mounts, steel brackets, and performance polyurethane bushings. Multiple bushing stiffness options allow the ESK4 to be configured for anything from a street-driven K-swap to a dedicated drag or competition build.
