Transform your fourth-generation Honda Accord with the Hasport CB1K5 K-Series Engine Swap Mount Kit, engineered for installing compatible Honda K20 or K24 engines paired with later-generation Honda Accord, Acura TSX, or Honda Civic Si manual transmissions into the 1990–1993 Honda Accord CB chassis.

Designed specifically for K-Series engine conversions, the Hasport CB1K5 provides the specialized engine and transmission mounting components needed to replace the factory F-Series drivetrain with Honda's popular K-Series engine platform.

The CB1K5 is designed for compatible manual transmissions from the 2008–2013 Honda Accord 2.4L, 2009–2014 Acura TSX 2.4L, and 2012–2015 Honda Civic Si 2.4L. These transmissions use different mounting configurations than earlier K-Series transmission families, making the correct Hasport mount kit essential for proper installation.

Featuring Hasport's dual-height mounting design, precision-engineered construction, and performance polyurethane bushings, the CB1K5 provides dependable drivetrain support for naturally aspirated, turbocharged, and competition-oriented Honda Accord builds.

Whether you're building a high-revving K20-powered Accord, a high-torque K24 street car, or a custom forced-induction project, the Hasport CB1K5 delivers a purpose-built mounting solution for your K-Series conversion.

Designed for Fourth-Generation Honda Accord K-Series Swaps

The 1990–1993 Honda Accord provides a versatile platform for custom engine conversions and performance upgrades.

The Hasport CB1K5 allows builders to replace the original F-Series engine with a compatible Honda K-Series drivetrain while using supported later-generation Accord, TSX, or Civic Si manual transmissions.

Key benefits include:

• Application-specific mounting for the 1990–1993 Honda Accord CB chassis.

• Compatibility with supported Honda K20 and K24 engines.

• Support for 2008–2013 Honda Accord 2.4L manual transmissions.

• Support for 2009–2014 Acura TSX 2.4L manual transmissions.

• Support for 2012–2015 Honda Civic Si 2.4L manual transmissions.

• Dual-height mounting geometry for optimized drivetrain positioning.

• Improved axle alignment considerations.

• Engine placement designed around hood and ground clearance.

• Reduced excessive drivetrain movement.

• Durable mounting support for street and motorsport applications.

Later-Generation Accord, TSX and Civic Si Transmission Compatibility

The Hasport CB1K5 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 use mounting arrangements different from the Acura RSX, earlier Civic Si, and earlier Accord/TSX manual transmissions.

The CB1K5 provides the appropriate mounting configuration for this later-generation transmission family.

For builds using Acura RSX or 2002–2011 Civic Si manual transmissions, the corresponding earlier-transmission mount configuration is required.

For builds using 2003–2007 Accord or 2004–2008 TSX manual transmissions, Hasport offers the CB1K4.

Dual-Height K20 and K24 Mounting System

One of the key advantages of the Hasport CB1K5 is its dual-height mounting design.

Honda K20 and K24 engines have different block heights, which affect cylinder head positioning, hood clearance, and overall drivetrain placement.

Hasport engineered its CB-chassis K-Series mounting system to accommodate these differences while maintaining consistent cylinder head positioning between supported engine configurations.

Benefits include:

• Optimized engine placement for compatible K20 and K24 engines.

• Improved hood clearance considerations.

• Better ground clearance management.

• Consistent cylinder head positioning.

• Simplified intake manifold and intake system fitment planning.

• More consistent header and exhaust positioning.

• Greater flexibility when designing turbocharger systems.

• Improved drivetrain alignment within the Accord chassis.

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 CB1K5 uses application-specific mounting components designed to withstand the demands of performance-oriented engine conversions.

Combined with performance polyurethane bushings, the mounting system helps maintain consistent drivetrain positioning during acceleration, deceleration, and shifting.

Performance Polyurethane Bushings

The Hasport CB1K5 is available with four polyurethane bushing hardness options.

Unlike conventional factory rubber mounts, polyurethane bushings help reduce excessive engine and transmission movement under load.

Reducing drivetrain movement can improve engine stability and help maintain more consistent transmission positioning during aggressive driving.

Builders can select the appropriate bushing hardness based on their intended application, from daily driving to dedicated competition use.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a 1990–1993 Honda Accord CB chassis.

2. Confirm Engine Compatibility: Identify the exact Honda K20 or K24 engine being installed.

3. Verify Transmission Compatibility: Confirm that the selected transmission is from a supported 2008–2013 Accord, 2009–2014 TSX, or 2012–2015 Civic Si application.

4. Verify Engine Block Bracket Requirements: Confirm whether the selected engine requires an additional Honda or Hasport engine-side mounting bracket.

5. Inspect the Engine Bay: Check the condition of the frame rails, factory mounting points, and surrounding components before beginning the conversion.

6. Prepare for Chassis Modification: The factory transmission mounting bracket must be cut from the frame rail to accommodate the K-Series mounting system.

7. Plan Supporting Swap Components: Additional axles, intermediate shaft, wiring, ECU, shifter, shift cables, clutch, cooling, fuel system, and exhaust components will be required.

8. Support the Engine and Transmission: Use appropriate lifting equipment and drivetrain supports.

9. Remove the Factory Drivetrain: Follow the applicable Honda service procedures.

10. Complete Required Chassis Modifications: Remove the factory transmission bracket according to Hasport's installation instructions.

11. Install the Hasport Mounting Components: Position the mounts and brackets according to the manufacturer's instructions.

12. Verify Engine Height and Positioning: Confirm that the K20 or K24 configuration provides the intended engine placement.

13. Inspect Axle Alignment: Verify proper axle engagement, operating angles, and clearance.

14. Check Hood and Ground Clearance: Confirm that the installed drivetrain does not interfere with surrounding components.

15. Verify Intake and Exhaust Fitment: Check compatibility with the selected intake manifold, header, exhaust routing, and any forced-induction components.

16. Complete Supporting Systems: Install and verify the required wiring, ECU, fuel, cooling, clutch, and shifter components.

17. Torque Mounting Hardware: Follow Hasport's installation instructions and applicable Honda factory torque specifications.

18. Perform a Final Inspection: Verify mounting hardware, drivetrain positioning, and surrounding component clearances before operating the vehicle.

19. Recheck After Initial Use: Inspect mounting hardware and drivetrain components after the initial driving period.

Professional installation is strongly recommended because K-Series engine conversions require chassis modifications and extensive drivetrain integration.
