Transform your third-generation Honda Fit into a K-Series-powered performance machine with the Hasport GKK3 K-Series Engine Swap Mount Kit, engineered for installing compatible Honda K20 or K24 engines with later-generation Honda and Acura manual transmissions into the 2015–2019 Honda Fit GK chassis.

Designed specifically for K-Series engine conversions, the Hasport GKK3 provides the specialized mounting components needed to replace the factory L-Series drivetrain with Honda's popular K-Series engine platform.

The GKK3 is configured for compatible manual transmissions from the 2008–2013 Honda Accord, 2009–2014 Acura TSX, and 2012–2015 Honda Civic Si. These transmissions use a different mounting arrangement than earlier Acura RSX, Civic Si, Accord, and TSX transmissions, making the correct Hasport mounting system essential for proper drivetrain positioning.

Featuring Hasport's dual-height mounting design, optimized engine placement, precision-engineered construction, and performance polyurethane bushings, the GKK3 provides a dependable foundation for naturally aspirated, turbocharged, and competition-oriented K-Series Honda Fit builds.

Whether you're building a high-revving K20 street car, a torque-focused K24 Honda Fit, or a custom forced-induction project, the Hasport GKK3 delivers the drivetrain support needed for a serious engine conversion.

Designed for Third-Generation Honda Fit K-Series Swaps

The 2015–2019 Honda Fit GK chassis provides a lightweight, compact platform with excellent potential for performance-oriented engine conversions.

The Hasport GKK3 allows builders to replace the factory L-Series engine with a compatible Honda K-Series drivetrain while maintaining engine positioning engineered specifically for the GK chassis.

Key benefits include:

• Application-specific mounting for the 2015–2019 Honda Fit.

• Compatibility with supported Honda K20 and K24 engines.

• Support for later-generation Accord, TSX, and Civic Si manual transmissions.

• Optimized engine placement for axle alignment.

• Improved consideration for hood and ground clearance.

• Reduced excessive drivetrain movement.

• Increased flexibility for naturally aspirated and forced-induction applications.

Later-Generation Accord, TSX and Civic Si Transmission Compatibility

The Hasport GKK3 is specifically designed for compatible K-Series manual transmissions from the following vehicles:

• 2008–2013 Honda Accord 2.4L Manual

• 2009–2014 Acura TSX 2.4L Manual

• 2012–2015 Honda Civic Si 2.4L Manual

These transmissions feature mounting arrangements different from earlier K-Series manual transmissions.

The GKK3 provides the appropriate mounting configuration for the supported transmission family, allowing builders to use these later-generation drivetrains in a K-Series-swapped Honda Fit.

For applications using a 2003–2007 Honda Accord or 2004–2008 Acura TSX manual transmission, Hasport offers the GKK2 mounting configuration instead.

Dual-Height K20 and K24 Mounting System

The Hasport GKK3 features a dual-height mounting design intended to accommodate the different engine block heights of compatible Honda K20 and K24 engines.

Because the K24 engine block is taller than the K20, the two engines require different mounting arrangements to maintain consistent cylinder head positioning.

Hasport addresses this difference with engine-specific mounting configurations.

GKK3-20 – K20 Engine Applications

Designed for compatible Honda K20 engines using the supported later-generation manual transmission family.

GKK3-24 – K24 Engine Applications

Designed for compatible Honda K24 engines using the supported later-generation manual transmission family.

The dual-height system offers several advantages:

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

• Improved compatibility planning for intake manifolds and intake systems.

• More consistent header and exhaust positioning.

• Greater flexibility when designing turbocharger systems.

• Optimized engine placement for hood and ground clearance.

• Proper drivetrain alignment for the supported chassis.

Important: Select the GKK3 configuration that matches the engine being installed.

Optimized Engine Placement

Proper drivetrain positioning is especially important when installing a larger K-Series engine into the compact Honda Fit engine bay.

Hasport engineered the GKK3 mounting system with consideration for:

• Axle alignment

• Ground clearance

• Hood clearance

• Engine and transmission positioning

• Surrounding engine bay component clearance

The GKK3 provides the foundation for a properly planned K-Series conversion while helping maintain consistent drivetrain positioning.

Precision-Engineered Hasport Construction

Hasport develops its engine mounting systems using CAD/CAM engineering technology to achieve accurate fitment, consistent manufacturing quality, and dependable structural strength.

The GKK3 combines application-specific mounting components with performance polyurethane bushings designed to support the drivetrain during demanding street and competition use.

Performance Polyurethane Bushings

Hasport's polyurethane bushings help reduce excessive engine and transmission movement compared with conventional factory rubber mounts.

Limiting drivetrain movement helps maintain more consistent engine positioning during acceleration, deceleration, and shifting.

Multiple bushing hardness options allow builders to select the appropriate balance between street comfort and drivetrain rigidity.
