LE5 Stage 2 Fuel Injector Kit

The RPM Motorsports Solstice/SKY 2.4L LE5 Stage 2 Kit is designed to enhance the performance of your 2.4L LE5 engine, particularly addressing limitations discovered through competitive use. Years of supporting race teams revealed consistent feedback regarding header cracking from lean conditions and a significant power drop-off above 3500 RPM. Investigations found that the stock 24 lb fuel injectors quickly reached their 100% duty cycle limit, especially when combined with modifications like a cold air intake or high-flow downpipe. This kit directly resolves these issues by incorporating fuel injectors that are 50% larger, enabling proper fueling across all driving conditions and eliminating lean conditions. With improved fueling capacity, this kit allows for increased timing to generate more power, especially above 3500 RPM. Independently dyno-tested results from RPM customers show a gain from the factory stock 135 wheel HP / 140 lb-ft of wheel torque to 168 wheel HP / 180 lb-ft of wheel torque when equipped with a cold air intake and a 400-cell high-flow catalytic converter. The kit also includes access to RPM-Motorsports' V-Tuner service, a remote tuning solution that personalizes the ECM calibration to your specific vehicle and any additional modifications. Tuning is essential for realizing the full potential of this kit. Customers can either use a loaner V-Tuner device, which may involve a 3-5 week waitlist, or purchase their own tuning interface for $399 to expedite the process and gain long-term tuning support for future modifications or diagnostics.
