Solstice / SKY 2.4L LE5 Stage 2 Kit

This kit was found from years of using the 2.4L in a competitive environment. As RPM supported race teams around the country using GM’s 2.4L LE5 engine we continued to get the same feedback.. Headers were cracking due to excessive lean conditions and there was no power above 3500rpm’s.. So we spent a few days trackside running one of our own cars only to find that the stock 24# fuel injectors were hitting 100% duty cycle very quickly and they hit their max even sooner with things like a Cold Air Intake and/or High-Flow Down-pipe bolted onto the engine. The 2.4 was under equipped from the get-go as they say..


2006-2010 Solstice & Sky 2.4L Stage 2 Kit

We contacted General Motors, and with their support, we found a direct replacement injector that was 50% larger. What does this mean?

With the injector capable of 50% more duty cycle, we are now able to “properly” fuel the car in all types of driving scenarios.

No more lean condition caused by small fuel injectors.

More power over 3500 RPMs; we can even add more timing to help make additional power.

The Dirt: Factory/stock 2.4L in a rear-wheel-drive platform makes about 135 wheel HP / 140 lbs of wheel TQ. Our Stage 2 package with a cold air intake and 400-cell count high-flow cat has been independently dyno’ed to make 168 wheel HP / 180 lbs wheel TQ. (Dyno results were submitted by past RPM customers; some cars may make more, some make less).

Let’s Talk Tuning: RPM-Motorsports pioneered ECM tuning for the Kappa platform back in 2006. We were the first company to release pre-programmed Stage 1 calibrated ECMs in partnership with GM. From there, we took to the streets—or the air—as it was setting up live tuning sessions all over the country, tuning sometimes 26 cars in a 15-hour period! But then in 2008, we released our V-Tuner service; this revolutionized the way that ECM tuning was delivered. We wanted to be able to offer that 100% unique tuning service for each of our clients because we learned very quickly that none of these cars were exactly the same and required specific tuning from car to car.

We developed our remote access V-Tuner kit that we loan out as part of the tuning purchase. This allows us to remotely tune your car, taking into account everything that makes your car specific and special, plus any bolt-on mods that you have added. You will not find a more custom remote tune on the market!

The fine print as they say: As we normally have around 18 V-Tuner units in circulation traveling around the world, we do inherently have a waitlist to receive a loaner device. Please allow 3-5 weeks from the date you placed your order for a loaner kit to become available for your project.

I can’t wait! No problem; use the option to purchase your own tuning interface. This adds $399 to your total, but let’s talk about how $399 could be the best investment you make. By purchasing your own interface outright, you not only get to skip the loaner line and can get your project tuned ASAP, but you will get long-term support—yes, long-term support. This means that if you purchase an RPM Motorsports component after your original install, give us a call, and we’ll calibrate your car for the new mod—or, in 6 months, 1 year, 4 years down the road, and you throw a check engine light—give us a call. By having your own interface, we can help! We can save you thousands of $$$ by helping you diagnose your car by remote vs. taking it into the dealership. (Note: The interface must be part of the original package purchase in order for the tuning credits that we include with the package to be allocated to your interface.)
