What is a 'top feed conversion' and what modifications are needed?

A top feed conversion means the injectors will be installed from the top of the fuel rail, pointing down into the intake manifold. This typically requires compatible top feed fuel rails and may involve modifications to your intake manifold or associated plumbing to accommodate the new injector style and orientation.

Are these injectors compatible with my stock ECU?

Yes, these are high impedance injectors, which means they are designed to work with most factory electronic control units (ECUs) without the need for an additional resistor box. This simplifies the wiring and installation process compared to low impedance injectors.

What else might I need to install these injectors?

To effectively use these 1000cc injectors, you will likely need a higher-flow fuel pump to supply adequate fuel volume, and a professional ECU tune to properly calibrate the fuel delivery for your specific engine modifications and ensure optimal performance and reliability.

Product Details

If you're looking to significantly increase the fuel flow for your 1993-1998 Toyota Supra Twin Turbo, these 1000cc high impedance injectors from DeatschWerks are a solid choice. They are designed to replace your stock injectors and are part of a top feed conversion, meaning they'll require compatible fuel rail and intake manifold modifications to fit correctly. This set includes six matched injectors, ensuring consistent fuel delivery across all cylinders, which is crucial for optimal engine performance and tuning, especially when pushing your engine beyond its original specifications.

DeatschWerks has been a well-known name in performance fuel systems since 2004, and these injectors are built to their standards. They are high impedance, which means they are compatible with most factory ECU systems without the need for an external injector resistor box, simplifying installation. The 1000cc flow rate is substantial, making them suitable for modified engines running higher boost pressures or alternative fuels. Each injector is precisely matched to the others in the set, a critical step for ensuring your engine runs smoothly and can be tuned accurately. The 14mm O-ring size is standard for many top feed injector conversions.

When undertaking a fuel system upgrade like this, it's important to consider that these injectors will likely require a corresponding fuel pump upgrade and ECU tuning to take full advantage of their increased flow capacity. Ensure you have the necessary supporting modifications and a qualified tuner lined up before installation. Please note that these injectors are not CARB approved and cannot be shipped to California.
