Aaron Demers
Check out Aaron Demers’ ‘93 LX running a Royal Flush! This is on his son’s car with original paint and interior. They are both trying to push the car into the 10s, and they are hoping the Royal Flush + 150 shot of nitrous will do just that! Be sure to check it out, and thanks again Aaron for sending in the pictures and video.

What we offer
Everything you need to upgrade, tune, and take control—whether you're converting from carb or building a high-performance EFI system from the ground up.
Ditch the carb and upgrade your classic or modern engine with one of our easy-to-install EFI systems. Whether you choose our Throttle Body Injection (TBI) kits for their affordability and simplicity, or go all-in with Multi-Port EFI (MPEFI) for maximum tunability and horsepower potential, we’ve got the right fit for your build.
TBI systems like the Killshot or Deuces Wild offer a retro look with modern reliability—perfect for street cruisers and weekend warriors. If you're after finer control, sequential injection, or running boost, our Wild Card and Royal Flush multi-port systems give you the tools to unlock your engine’s full potential.
Not sure which to choose? Our detailed guides and real-human support make finding the right system quick and painless.
Running a late-model LS, LT, HEMI, or other modern platform? Our Jackpot Series EFI systems are built to give you full control of your high-performance engine with modern tuning, expandability, and seamless integration.
Choose from TBI or Multi-Port EFI options depending on your goals—whether you’re swapping into a restomod, dialing in a boosted setup, or just want a cleaner, more tunable alternative to factory electronics. All Jackpot systems support both 24x and 58x crank triggers, are boost-ready, and are compatible with drive-by-cable or (select models) drive-by-wire setups.
From the streamlined Jackpot Lite to the fully featured Jackpot LS Pro, you get support for transmission control, sequential injection, multiple O2 sensors, and more—all without needing factory ECUs or complicated re-flashes.
Aces delivers a full lineup of performance components to support your build from top to bottom. Pair your EFI kit with CDI ignition systems, high-energy distributors, coils, and manifolds that are engineered for seamless compatibility and serious spark.
Want to go deeper? Our Top End and Master Kits bundle everything you need—from throttle body to fuel delivery—taking the guesswork out of custom builds. Whether you're piecing together a street machine or assembling a boosted track car, we offer the parts, packages, and support to do it right the first time.
Everything we make is designed to work together, so you spend less time troubleshooting and more time turning the key.

Adam Wichers
Adam Wichers’ 1986 Toyota Corolla AE86 GTS has been heavily upgraded with modern performance parts while keeping the car’s original character. Power comes from a 5.3L aluminum LS engine with an ACES Jackpot system, paired with a T56 manual transmission. This setup delivers strong performance and a true driver-focused feel. A Fox 8.8 rear end was added to handle the increased power and improve durability. The suspension has also been fully addressed. The car runs a full T3 suspension setup along with Annex Suspension Club Sport Pro coilovers. Together, these components improve handling, stability, and overall feel.

Here is a customers Camaro we just finished the swap to fuel injection. After doing some research we thought we would try your aces throttle body kit with the inline pump. Installation was easy, finding where to run the wires was the hardest part. We finally started the car today and drove it for the first time with the fuel injection. It runs great. Just a couple small things to finish up before it goes back to the customer. The car is a 1977 Camaro with a 350 ci. Turbo 350 trans. We are using your distributor and coil with the throttle body. We made a custom bracket to mount the touch screen on the center console. We think this turned out real nice.

Donavan McDaniel
So, Donavan McDaniel reached out to us this week and showed off his 84 Chevy S10 Durango, and can we just say it looks AWESOME! The truck is a standard cab long bed. He claims it to be a survivor as it came from Ohio with very little rust. Donavan has since addressed the rust, and is putting a 5.3 and 5 speed manual in it from a Colorado. It is not running yet (although it will be running a Jackpot), but Donavan will begin addressing it when he gets back from deployment. Thank you for your service Donavan, and thank you for sending in your beautiful build!

For a first time engine build and tuning, Travis did great work! He built and tuned this 1990 C1500 and used our KillShot EFI to bring it to life. E85, 11:1 compression, forged internals, and an Edelbrock RPM Air Gap to top it off. This is how you start 🔥
