The Porsche 944 is a celebrated classic, and with modern engineering ingenuity, we can enhance its performance to meet contemporary standards.
Engaging in an engine swap with a 2JZ engine from Toyota is a popular modification that offers the 944 a significant boost in power and reliability.
The 3.0-liter inline-six 2JZ, known for its strength and capability to handle substantial power increases, is a highly sought-after choice for engine conversions.
We recognize the importance of precision in such an endeavor.
Swap kits designed specifically for the 944-2JZ conversion streamline the process, addressing crucial fitment and compatibility issues.
These kits often include custom mounts, brackets, and hardware to ensure that the new engine not only fits but performs seamlessly with the 944’s existing systems.
As enthusiasts looking to revitalize the driving experience of our 944, a well-engineered swap kit is the gateway to transforming it into a modern-day performer.

Choosing the Right Components for Your 944 Engine Swap
Embarking on a Porsche 944 engine swap project, especially when considering a 2JZ conversion, demands careful selection of components for compatibility and performance.
Let’s ensure you start with a solid foundation and choose parts that complement the iconic performance of models such as the 924, 944 Turbo (951), or the standard 944.
Understanding the Basics of Engine Swapping
Engine swapping requires detailed knowledge of both the vehicle and the engine you intend to install.
In our case, the 2JZ is a high-performance, inline-6 engine, which contrasts with the 944’s original inline-4 or V8 options popular in LS swaps.
We need to verify engine mount compatibility, component clearances, and the integrity of the drivetrain to cope with increased power.
Selecting the Appropriate Swap Kit
The market offers various swap kits but selecting one that caters specifically to a 2JZ-GTE engine into a Porsche 944 chassis is crucial.
These kits should contain all necessary hardware, from custom mounts to modified bell housings, and appropriately tailored wiring harnesses and ECU solutions.
Compatibility and Performance Considerations
Our main objective is to enhance the 944’s driving dynamics without compromising the vehicle’s structural integrity or reliability.
Therefore, compatibility with the 944’s suspension, brakes, and gearbox is as crucial as the engine fitment.
Upgraded components may be necessary to handle the 2JZ’s power, like stronger axles or a more robust clutch.
| Component | Necessity | Performance Impact |
| 2JZ Engine Mounts | Essential | Stability & Alignment |
| Custom Wiring Harness | Essential | Electrical Integration |
| Upgraded Drivetrain Components | Advisable | Handling Increased Torque |
| High-Performance Clutch | Advisable | Transmission Longevity |
By being systematic and thorough in our approach to component selection, we set the foundation for a successful marriage between the robust 2JZ engine and the classic Porsche 944, unlocking a new realm of performance for this revered chassis.
Installation Process and Technical Details
The Porsche 944 2JZ swap is an intricate process that requires specific modifications, especially when ensuring that the engine fits and operates properly in its new home.
We’ll guide you through the crucial steps involving the mounting of the engine and transmission, as well as the necessary modifications to the exhaust and cooling systems.
Mounting the Engine and Transmission
Engine Mounts and Bellhousing
We start by aligning the 2JZ engine using custom-engineered engine mounts for perfect placement within the 944’s bay.
The bellhousing connects the 2JZ to the Porsche’s torque tube, and a robust bellhousing adapter is essential for this task.
The adapter allows for the original transmission to mate with the new engine, preserving the car’s balanced weight distribution.
| Component | Details |
| Oil Pan | Custom Fabricated Upper Oil Pan |
| Transmission | Utilize Original with Adapter |
A specially designed flywheel and a spec clutch facilitate the connection to the Porsche gearbox, ensuring a smooth transfer of power.
A compatible starter from the Boost Brothers Garage kit can be employed to align with the flywheel and bellhousing.
Exhaust and Cooling System Modifications
The exhaust system in a 2JZ engine swap must be custom fabricated to fit within the 944’s structure.
The engine’s position and the room available under the car dictate the new exhaust routing, which often includes a bespoke manifold and downpipe to accommodate the change.
The crossmember needs modification for adequate clearance of the custom oil pan.
This is required to prevent any interference with the steering and suspension components, ensuring that the low profile of the oil pan does not affect the vehicle dynamics.
It’s imperative to ensure that the cooling system is capable of handling the increased thermal output of the 2JZ engine.
Upgrades to the radiator and custom hoses may be necessary for optimal engine temperature regulation.
Enhancing Performance and Reliability
When we undertake a Porsche 944 2JZ swap, the main objectives are to significantly increase horsepower and ensure steady reliability.
Let’s explore the essentials in achieving a successful powertrain upgrade and the corresponding improvement in suspension for refined drivability.
Upgrades for Increased Horsepower
The heart of enhancing a Porsche 944’s performance lies in upgrading to the 2JZ engine, renowned for its high horsepower potential.
By adding a turbo, tuning the engine, and installing high-performance components, we unlock a new level of power.
Horsepower Enhancements:
- Implementing a high-quality turbocharger to boost power.
- Advanced ECU tuning for optimizing fuel and ignition.
- Upgrading to a performance pulley system for better throttle response.
Boosting the engine’s horsepower with these upgrades not only augments performance but, when done properly, also contributes to the overall reliability of the vehicle.
Improving the Suspension and Drivability
With increased power, it becomes imperative to upgrade the suspension system to handle the added force and maintain a smooth ride.
- Adjustable coilovers for a tailored driving experience.
- Upgraded anti-roll bars to reduce body roll during corners.
- G Force performance products to ensure component durability.
Reliable and responsive suspension components not only complement the power but also contribute to a Porsche 944 that is as capable on daily drives as it is on the track.
Finishing Touches and Aesthetic Considerations
When conducting a 2JZ swap on a Porsche 944, the final steps involve not only ensuring all components function correctly but also that the car’s appearance is top-notch. This includes attention to the integration of the engine bay and the exterior’s finish.
Customizing the Exterior and Engine Bay
The factory hood of the Porsche 944 may require modifications or even replacement to accommodate the new 2JZ engine.
These adjustments must be precise to maintain the clean lines of the car’s classic silhouette.
Within the engine bay, installing a billet valve cover and a custom oil pan/pickup can add a striking visual impact while ensuring functionality with the larger engine.
It’s essential that all components, including the gasket, oil filter block, and power steering pump mount, not only enhance performance but also contribute aesthetically to a cohesive and professional look.
- Billet valve cover
- Custom oil pan/pickup
- Front crossmember/subframe spacers
Attention to Detail for a Factory Finish Look
Our focus transitions to the intricacies of the swap that gives the Porsche 944 a semblance of untouched factory finesse.
Integrating a GM throwout bearing/slave cylinder, mounting the pressure plate, and attaching an LS style flywheel, coupled with a Corvette C5 bellhousing, requires precision.
These components should be linked seamlessly with the bellhousing adapter plate and custom-engineered 321 stainless steel long tube 1-7/8″ headers leading to a Magnaflow muffler, signifying a high-caliber conversion.
We create a bespoke aesthetic with a remote clutch bleeder and VSS sensor adapter while retaining the original 944 power steering pump bracket for an unaltered external appearance.
| Component | Function & Aesthetic Contribution |
| Corvette C5 bellhousing & Adapter Plate | Integrates seamlessly for proper fitment; remains inconspicuous for a clean look. |
| GF-LS944-EXH Headers | Custom-fit to route efficiently; enhances both appearance and exhaust flow. |
| Remote Clutch Bleeder | Allows for easy maintenance without disturbing the factory look. |
By handling each aspect of the swap with scrupulous attention to detail, we not only guarantee a powerful performance but also preserve and enhance the Porsche 944’s iconic aesthetic.
We love what we do, and it shows in everything we do and more. We share our knowledge, here on Ran When Parked.
