Do you have a Japanese classic car that you just love but hate the outdated feel? Do you wish that the drum brakes were a modern Big Brake Kit?

4worldlovers: We build performance engines and wiring harnesses, as well as offering consultations on engine + parts combinations for your individual project and setup.

Flag Motorsports was created to support anyone with a passion for performance cars. We don’t discriminate about what type of racing you enjoy, or whether your car is a restomod classic vs a modern sports car.

Our team has a range of cars, from old-school muscle to modern track focused supercars. Find us at the track when we’re not in the shop - we hope we’ll see you there as well.

Flags are used in most motorsports to communicate messages to drivers on the track. We’ve commandeered that idea for engine packages. Below are a few of our most common options, though we’re always excited to tackle custom projects.

In racing, the green flag means go. Our Green Flag engine package is designed to have you taking off, typically we recommend a built LS rated to about 500 horsepower at the crank. Specific configurations can range depending on application, but this healthy conservative build is a track and street favorite.

The yellow flag is technically a signal for caution. We use this package for a milder daily driver build, or specifically for California applications we can build a CARB legal engine. These CARB legal engines are great for clients looking to perform a smog legal LS swap, or to make a bit more power and still pass smog.


There’s one more lap in the race. Are you ready to haul ass? Hammer down, and let us build you an engine that has others asking what’s under the hood. Blown, NOS, turbos, or NA but running into the 700s+ for horsepower, whatever strikes your fancy. This is for the adrenaline junkies who want to fear their car.


When considering either an engine swap, or a rebuild/new engine there are quite a few factors to take into consideration. Don’t browse forums for 6 hours, or ask your buddy with a junkyard 5.3 what to do.

Flag Motorsports offers guidance for any engine, with a specific focus on the LSX platform.

Discuss power goals, application, chassis, and more. Our experts will use this information to suggest the best engine combination for you. It’s not as simple as “you’d do well with an LS1”. It’s more like “your best bet for road racing is a destroked LS3 so you can shift closer to 8000 or 9000 RPM, but you’ll also want a dry sump setup to avoid oiling issues. For a cam you’ll want longer duration…” and more. We’ll explain what parts to use, why to use them, and how it effects the build outcome.
