At Tysautoworks Performance, we love taking the legendary BMW N54 to its limits. This 335i isn’t just a fast car—it’s a masterclass in high-boost, bolt-on tuning, pushing over 700 horsepower on stock internals with a fully engineered setup.
From the 6870 Precision single turbo to the Doc Race single turbo kit, every component is carefully selected to maximize power, reliability, and drivability.
🔥 Engine Overview: N54 Single Turbo Potential
The N54 engine is legendary among BMW enthusiasts for its twin-turbo design, closed-deck block, and strong internals. Stock, it can handle moderate power increases—but when done correctly, the N54 can exceed 700 HP without engine failure.
Key to success:
- Proper supporting mods
- Correct fueling and boost control
- High-quality turbo and intake components
This 335i is proof that stock internals don’t limit high-power builds when done professionally.
⚡ Build Highlights
1️⃣ 6870 Precision Single Turbo
- Capable of 700+ HP safely
- Handles 30+ PSI of boost
- Smooth power delivery across the rev range
This turbo was chosen for balance between top-end power and spool time, making the car drivable on the street and deadly on the track.
2️⃣ Doc Race Single Turbo Kit
- Custom manifold and piping
- Optimized for high-pressure airflow
- Supports boost stability at over 30 PSI
Without a quality kit, single turbo conversions risk heat soak, turbo lag, and uneven boost—this kit solves those issues.
3️⃣ Motive Reflex Port Injection
- Solves fueling limitations for high-boost setups
- Prevents knock and detonation
- Critical for keeping stock internals safe at 700+ HP
Port injection ensures the engine receives the right amount of fuel across the rev range, improving both reliability and performance.
4️⃣ Upgraded Intake Manifold
- Improves airflow into the engine
- Maximizes turbo efficiency
- Works in harmony with port injection for optimal fueling and power
5️⃣ Dual Catch Cans by Burger Motorsports
- Essential for high-boost N54 builds
- Reduces crankcase pressure
- Protects turbo and intake from oil contamination
At 30+ PSI, catch cans are critical to keep the engine healthy and responsive.
🧠 How This Build Makes 700+ HP on Stock Internals
Many shops push power without considering engine stress. At Tysautoworks Performance:
- Stock internals are carefully monitored and supported
- Fueling is upgraded with Motive Reflex Port Injection
- Turbo efficiency maximized with Doc Race kit & intake manifold
- Boost is stabilized at 30+ PSI with proper tuning and catch cans
The result: insane power with reliability, not just “numbers on a dyno.”
📊 Real-World Numbers
