Upgrade your fourth-generation Honda Civic or second-generation CRX with the Hasport EFD2 D-Series Engine Swap Mount Kit, engineered for installing compatible later-generation Honda D-Series engines into the 1988–1991 Honda Civic and CRX chassis.

Designed specifically for enthusiasts looking to modernize their EF-platform drivetrain, the Hasport EFD2 provides the specialized mounting components needed to install compatible 1992–2000 Honda D-Series engines while maintaining proper engine and transmission positioning.

Unlike the Hasport EFSTK, which is intended for original-generation 1988–1991 D-Series applications, the EFD2 accommodates the different engine-side mounting configurations found on supported later-generation D-Series engines.

Featuring precision-engineered mounting components, durable construction, and performance polyurethane bushings, the EFD2 provides a dependable mounting foundation for naturally aspirated, turbocharged, and street-oriented D-Series engine conversions.

Designed for Later-Generation D-Series Engine Swaps

Honda's D-Series engine family includes several popular SOHC VTEC and non-VTEC configurations used in 1992–2000 Honda Civic applications.

The Hasport EFD2 allows builders to install compatible later-generation D-Series engines into the earlier EF chassis without relying on improvised engine mounting solutions.

Popular engine swap applications include:

• Honda D16Z6 SOHC VTEC

• Honda D16Y7 SOHC

• Honda D16Y8 SOHC VTEC

• Other compatible 1992–2000 D-Series engines

These engines offer access to updated fuel injection systems, VTEC technology on select models, and extensive aftermarket performance support.

Engineered for Two-Bolt D-Series Engine Mounting Configurations

The EFD2 is designed around the later D-Series engine-side mounting arrangement used on compatible engines.

This mounting configuration differs from the original 1988–1991 D-Series setup, making proper engine-side bracket compatibility essential.

The EFD2 is particularly relevant for builders installing compatible 1992–1995 D-Series engines with the two-bolt engine block bracket arrangement or supported 1996–2000 D-Series engines.

Improved Drivetrain Stability

Factory rubber engine mounts can deteriorate over time, allowing excessive drivetrain movement during acceleration, deceleration, and shifting.

Hasport's performance polyurethane bushings help reduce unwanted engine movement while maintaining consistent drivetrain positioning.

This is especially beneficial for modified D-Series engines producing increased torque or operating under demanding driving conditions.

Precision-Engineered Hasport Construction

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

The EFD2 is designed to provide application-specific mounting support for later-generation D-Series engines installed in the EF chassis.
