Performance Builds
Whether you want a clean Stage 1 or a full build, we plan it as a system: power, fueling, cooling, drivetrain and brakes, on a healthy car, with every part installed in our shop.
We drive what we build
Our own shop car is a B58-powered 340i making 1,300 horsepower, built here with the same process we use on customer cars: health check first, fueling before boost, and a drivetrain that can hold the power.
Hardware is ours, tuning is theirs
We plan the build and install the parts. Software tuning is done by independent tuning specialists, and you work with the tuner directly on the calibration. Keeping those roles separate means each part of the build is handled by the people who do it every day.
Built right, not cheap
More power always costs more than the parts that make it. A proper build includes the fueling, cooling, drivetrain and brakes to support it, plus a healthy engine to start with. We'll be straight with you about cost and risk before anything is ordered. If the goal is the cheapest way to more boost, we're not the right shop; if you want it done properly, we'd love to build it.
Plan your build
Use our Build Your Car tool to pick your car, set a power goal and see the parts and supporting mods it takes with a ballpark price. Every build starts with a health check, compression or leak-down, a full scan and a look at known weak points, because power on a tired engine is money wasted.
What we do
- Intakes, charge pipes, intercoolers and heat exchangers
- Downpipes and exhaust
- Fueling: port injection, low-pressure fuel pumps, injectors and flex-fuel/E85
- Hybrid and big-single turbo upgrades
- Installing built transmissions from specialist builders, plus clutches, axles and driveshafts
- Oil and transmission coolers
- Brakes, suspension and tires to match the power
Flexible financing
Finance your build. Flexible terms available. Ask when you send your build.
Builds can be financed with flexible terms, so you can do it right the first time instead of cutting corners on supporting mods. Ask about financing when you send your build.
Street, track or competition
Street builds stay emissions-compliant with catted parts. If you're building a dedicated off-road or competition vehicle, tell us. The build tool has a competition option, and we'll talk through what that means for registration and inspection.

Common questions
Will more power hurt reliability?
A conservative, well-supported build on a healthy car is very reliable. Problems come from skipping supporting mods: fueling, cooling, ignition and drivetrain. That's why our build tool adds them automatically.
Can a modified car pass Massachusetts inspection?
Street builds using catted downpipes and emissions-compliant parts can pass as long as there are no warning lights and readiness monitors are set. Removing catalytic converters or emissions equipment won't pass and isn't legal on a road-registered car.
Do you tune cars?
No. We don't do software tuning in-house. Tuning is handled by independent tuning specialists, and we take care of the hardware, installation and supporting work.
