Upgrade your fourth-generation Honda Prelude with the Hasport BB1K5 K-Series Engine Swap Mount Kit, engineered for installing a compatible Honda K20 or K24 engine paired with a later-generation Honda or Acura K-Series manual transmission into the 1992–1996 Honda Prelude.

Designed specifically for the BB chassis, the Hasport BB1K5 provides the mounting foundation needed to replace the original H-Series or F-Series drivetrain with a modern Honda K-Series engine and transmission combination.

The BB1K5 is configured for compatible manual transmissions from the 2008–2013 Honda Accord, 2009–2014 Acura TSX, and 2012–2015 Honda Civic Si. These later-generation transmissions use a different mounting arrangement than earlier Acura RSX and Accord/TSX transmissions, making the correct Hasport mount kit essential for proper drivetrain positioning.

Featuring Hasport's dual-height mounting design, precision-engineered mounting components, and performance polyurethane bushings, the BB1K5 provides a dependable foundation for naturally aspirated, turbocharged, and competition-oriented K-Series Prelude builds.

Designed for Later-Generation K-Series Transmissions

The Hasport BB1K5 is specifically designed around compatible later-generation K-Series manual transmissions.

Supported transmission applications include:

• 2008–2013 Honda Accord 2.4L manual transmission

• 2009–2014 Acura TSX 2.4L manual transmission

• 2012–2015 Honda Civic Si 2.4L manual transmission

These transmissions feature mounting configurations that differ from the earlier Acura RSX, 2002–2011 Civic Si, and first-generation Accord/TSX K-Series manual transmissions.

The BB1K5 provides the appropriate mounting arrangement for the supported transmission family.

K20 and K24 Dual-Height Mounting System

Honda K20 and K24 engines have different engine block heights, which affect drivetrain positioning, hood clearance, ground clearance, and surrounding component fitment.

Hasport's dual-height mounting system accommodates compatible K20 and K24 engine configurations while helping maintain consistent cylinder head positioning.

This design offers several advantages:

• Optimized engine placement within the Prelude engine bay.

• Improved consideration for hood and ground clearance.

• Proper engine and transmission alignment.

• Consistent drivetrain positioning.

• Greater flexibility when planning intake, exhaust, and forced-induction configurations.

Precision-Engineered Hasport Construction

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

The BB1K5 combines application-specific mounting components with durable polyurethane bushings to provide reliable drivetrain support for demanding performance applications.

Performance Polyurethane Bushings

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

By limiting drivetrain movement during acceleration, deceleration, and shifting, the BB1K5 helps maintain more consistent engine and transmission positioning.

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

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

4. Inspect Engine-Side Brackets: Verify that all required K-Series mounting brackets and attachment points are present.

5. Remove the Factory Transmission Bracket: The original transmission mounting bracket must be cut from the frame rail as specified by Hasport.

6. Prepare the Chassis: Complete all required bracket removal and related modifications before final drivetrain installation.

7. Plan Supporting Swap Components: Additional axles, wiring, ECU, shifter, cooling, clutch, and exhaust components will be required.

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

9. Select the Correct Engine Height: Follow Hasport's instructions for the dual-height mounting configuration.

10. Install the Hasport Mounting Components: Position the engine and transmission mounts according to the manufacturer's installation instructions.

11. Verify Engine Positioning: Check hood clearance, oil pan clearance, and surrounding engine bay components.

12. Inspect Axle Alignment: Confirm proper axle engagement, operating angles, and clearance.

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

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

15. Torque Mounting Hardware: Follow Hasport's instructions and applicable Honda service specifications.

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