Transform your Honda CR-Z into a K-Series-powered performance machine with the Hasport ZFK1-20 K20 Engine Swap Mount Kit, specifically designed for installing compatible Honda K20A and K20Z engines into the 2011–2016 Honda CR-Z ZF chassis.

Engineered for use with compatible Acura RSX and 2002–2011 Honda Civic Si manual transmissions, the ZFK1-20 provides the specialized mounting components needed to properly position and support a K20 drivetrain in the compact CR-Z engine bay.

The Honda CR-Z combines a lightweight chassis, sporty handling characteristics, and distinctive styling, making it an excellent candidate for a high-performance engine conversion. Replacing the factory LEA-series hybrid powertrain with a K20 opens the door to a wide range of naturally aspirated, turbocharged, and track-oriented performance applications.

However, installing a K-Series engine into the CR-Z requires application-specific mounting components that account for engine positioning, transmission alignment, axle geometry, and available engine bay clearance.

The Hasport ZFK1-20 addresses these challenges with precision-engineered mounting brackets, performance polyurethane bushings, and Hasport's dual-height K-Series mounting system.

Designed Specifically for K20A/K20Z Engine Swaps

The Hasport ZFK1-20 is the K20-specific configuration of Hasport's ZFK engine swap mount family.

It is designed for compatible K20A and K20Z engines paired with supported manual transmissions originally found in:

• 2002–2006 Acura RSX

• 2002–2011 Honda Civic Si

The ZFK1-20 uses the appropriate engine-height configuration for the K20 engine family, helping maintain the intended drivetrain position within the CR-Z chassis.

Unlike the ZFK1-24, which is designed for K24 engines, the ZFK1-20 is specifically configured for the shorter K20 engine block.

Hasport Dual-Height Mounting System

One of the key features of the Hasport ZFK mount family is its dual-height mounting system.

Honda K20 and K24 engines have different block heights, which can affect cylinder head positioning, hood clearance, and the fitment of surrounding components.

Hasport's dual-height system is designed to maintain a consistent cylinder head position when using the corresponding K20 or K24 mount configuration.

This design provides several advantages:

• Optimized engine placement within the CR-Z engine bay.

• Consistent cylinder head positioning between supported K20 and K24 configurations.

• Improved consideration for hood and ground clearance.

• Proper drivetrain positioning for compatible axle configurations.

• More consistent intake manifold and exhaust header positioning.

• Greater flexibility when planning compatible turbocharger systems.

The ZFK1-20 is the appropriate configuration when using a compatible K20 engine with an RSX or 2002–2011 Civic Si manual transmission.

Precision-Engineered Construction

Hasport designs its engine mounting systems using advanced CAD/CAM engineering technology to optimize drivetrain positioning, component strength, and fitment.

The ZFK1-20 incorporates precision-manufactured mounting components and application-specific brackets engineered for the Honda CR-Z chassis.

The mounting system provides a durable foundation for street-driven performance builds, autocross applications, road racing, and drag racing.

Performance Polyurethane Bushings

The Hasport ZFK1-20 utilizes polyurethane bushings designed to provide increased resistance to drivetrain movement compared with conventional factory rubber engine mounts.

By reducing excessive engine rocking during acceleration, deceleration, and gear changes, the mounts help maintain more consistent engine and transmission positioning.

This can improve drivetrain response, support more predictable shifting, and help reduce movement that contributes to wheel hop.

Hasport offers four bushing hardness options, allowing builders to select the appropriate balance between drivetrain rigidity and passenger comfort.
