Product Details
Transform your second-generation Acura Integra into a K-Series-powered performance machine with the Innovative Mounts 99350 Steel K-Series Engine Conversion Mount Kit, specifically engineered for 1992–1993 Acura Integra non-GS-R models.
Designed for enthusiasts replacing the factory B-Series engine with a Honda K20 or properly configured K24 engine, the Innovative Mounts 99350 provides the specialized mounting components needed to position and secure a compatible K-Series drivetrain in the Integra chassis.
The 1992–1993 Acura Integra is a popular platform among Honda and Acura performance enthusiasts thanks to its lightweight construction, responsive handling, and extensive aftermarket support. Converting this classic chassis to a modern K-Series engine provides opportunities for increased horsepower, improved torque, and a wide range of performance upgrades.
However, installing a K-Series engine into a second-generation Integra requires specialized mounting components because the factory B-Series engine and transmission mounts are not designed for the replacement drivetrain.
The Innovative Mounts 99350 addresses these requirements with a purpose-built steel conversion mounting system featuring performance polyurethane bushings and a weld-in chassis mounting bracket.
Designed to accommodate compatible Integra models originally equipped with either manual or automatic transmissions, the 99350 supports conversions using specified K-Series manual transmissions.
Innovative Mounts incorporates CAD/CAM engineering, stress-analyzed components, and its proprietary True Torque Positioning Technology (TTPT) to provide a performance-oriented drivetrain mounting solution.
The polyurethane bushings help reduce excessive engine movement during acceleration, deceleration, and shifting, maintaining more consistent drivetrain positioning compared with conventional factory rubber mounts.
Whether you're building a naturally aspirated K20-powered Integra, developing a turbocharged K24 project, or preparing a dedicated drag racing or road racing vehicle, the Innovative Mounts 99350 provides the mounting foundation for a properly configured K-Series conversion.
Important: The 99350 is designed for 1992–1993 Acura Integra non-GS-R applications. It requires welding a self-locating bracket to the chassis and is not a direct bolt-in engine swap kit.

Available Polyurethane Bushing Hardness Options
75A – Black – Street / Performance
The softest available bushing option for the 99350.
Recommended for street-oriented Integra conversions where improved drivetrain stability is desired while retaining some vibration isolation.
Manufacturer horsepower guidance: approximately 250–400 HP.
85A – Grey – Performance / Race
Provides increased drivetrain rigidity for modified engines, aggressive driving, and competition applications.
Manufacturer horsepower guidance: approximately 400–500 HP.
95A – Red – Extreme Race
The stiffest available polyurethane option, intended for high-output engines and dedicated racing applications.
Manufacturer horsepower guidance: 500+ HP.
These horsepower ranges are manufacturer bushing selection guidelines rather than guaranteed load ratings or minimum horsepower requirements.
