Unlock 400 Horsepower from Your G37 VQ37VHR Engine – Here’s How!
If you’re ready to unleash the full potential of your VQ37VHR engine, we’ve got the ultimate guide to get you there. With the right combination of performance upgrades, you can achieve an impressive 400 horsepower. Let’s dive into the essential modifications you’ll need, along with recommendations from trusted brands.
1. Long Tube Intake Kit
The first step in maximizing your VQ37VHR is improving airflow to the engine. A high-performance long tube intake kit replaces the restrictive stock airbox, allowing for cooler, denser air to flow into the engine. This results in increased horsepower and throttle response. Here are some top options:
- Injen Cold Air Intake System – Known for precision engineering, Injen’s system enhances airflow while maintaining safe air-fuel ratios.
- Takeda Stage 2 Cold Air Intake System – This intake kit provides a perfect balance of performance and durability, featuring a high-flow dry filter.
- Stillen Generation 3 Ultra Long Tube Intake Kit – Designed for maximum power gains, this intake system delivers proven results in both performance and reliability.
2. Test Pipes / Front Pipes / Downpipes
Improving exhaust flow is crucial for performance. Test pipes (or front pipes) replace restrictive factory catalytic converters, allowing exhaust gases to exit more efficiently. This upgrade reduces backpressure, freeing up horsepower and giving your vehicle a more aggressive sound.
- Berk Technology Test Pipes – Crafted for performance and reliability, these pipes reduce restrictions without triggering check engine lights.
- Armytrix High-Flow Cat Pipes – These pipes enhance both power and sound, featuring high-flow catalytic converters.
- Invidia Test Pipe with High-Flow Cats – Known for their craftsmanship, Invidia’s test pipes optimize exhaust flow for noticeable gains.
3. Exhaust System
A performance exhaust system not only enhances sound but also supports the increased airflow from the intake and test pipes. By reducing backpressure and increasing exhaust velocity, these systems boost horsepower and torque.
- HKS Super Sound Master Muffler – Known for their rich exhaust note, HKS systems deliver performance without excessive noise.
- Stillen Stainless Steel Catback Exhaust System – Engineered for power and durability, this system delivers smooth exhaust flow and a deep, aggressive sound.
- Greddy Revolution RS Exhaust – A favorite for its lightweight design and tuned exhaust note.
4. Upgraded Camshafts
Upgrading the camshaft optimizes valve timing and lift, allowing the engine to breathe better at higher RPMs. This translates to significant power gains, especially when paired with other mods.
- JUN Regular Series Camshafts – JUN’s camshafts are engineered for maximum performance, improving both top-end power and mid-range torque.
5. Fuel System Components
With increased airflow and power demands, your engine needs more fuel to maintain the right air-fuel mixture. Upgraded fuel components ensure consistent delivery under higher loads.
- Radium Engineering Fuel Rail Kit – Designed for high-flow applications, this kit ensures optimal fuel distribution.
- Deatschwerks 2200cc Fuel Injectors – These injectors provide precise fuel delivery, ideal for high-performance builds.
- ISR Performance 340 LPH Fuel Pump Kit – Capable of supporting higher power levels, this pump is compatible with E85 fuel.
6. Long Tube Headers
Long tube headers improve exhaust scavenging, reducing backpressure and increasing horsepower. They are a must-have for maximizing exhaust flow efficiency.
- ISR Performance HGC Long Tube Headers – A cost-effective solution for improved power and sound.
- PPE Engineering Race Headers – Precision-engineered for maximum performance gains.
- DC Sports Stainless Steel Header – A reliable upgrade for both power and durability
7. Finish with a Custom Tune
After installing these mods, a custom tune is essential to optimize performance and ensure everything runs smoothly. A professional tuner can adjust your engine’s parameters to maximize horsepower and reliability. While we don’t sell tunes directly, we highly recommend pairing these upgrades with a reputable tuner to achieve the 450-horsepower mark.
