How to Turbo Your Infiniti G37: The Complete Guide
If you’re looking to transform your Infiniti G37 into a true powerhouse, installing a turbo kit is one of the most effective and rewarding modifications you can undertake. With the right setup, you can dramatically boost horsepower, improve throttle response, and enjoy a whole new level of driving excitement. This comprehensive guide breaks down everything you need to know about turbocharging your G37, from choosing the right kit to installation, maintenance, and cost-saving tips.
What Is a G37 Turbo Kit?
A G37 turbo kit is a bundle of components designed to force more air into your engine using a turbocharger. More air means more fuel can be added, and this results in increased horsepower and torque. Turbo kits typically include:
- Turbocharger(s) (single or twin)
- Intercooler
- Piping and couplings
- Wastegate and blow-off valve
- Fuel injectors and fuel pump upgrades
- Exhaust manifolds and downpipes
- Engine management or tuning device
Some kits are designed for stock engines, while others require additional supporting modifications to handle higher power levels safely.
Single vs. Twin Turbo: Understanding Your Options
When researching kits, you’ll often see the terms “single turbo” and “twin turbo.” Here’s a simple breakdown:
Single Turbo Kits
- One turbocharger is used.
- Typically easier and less expensive to install.
- Great for moderate power gains (350–500 HP).
- Smooth, linear power delivery.
Twin Turbo Kits
- Two small turbochargers (one for each engine bank).
- Offers even power delivery and quicker spool-up.
- Ideal for higher horsepower targets (500+ HP).
- More complex installation and tuning.
Your choice depends on your power goals, budget, and driving style.
Step-by-Step: How to Turbo Your G37
Successfully turbocharging your G37 involves careful planning and execution. Here’s what the process typically looks like:
1. Set Your Power Goals
- Decide how much horsepower you want; realistic street builds aim for 400–600 HP.
- Higher targets may require engine internal upgrades (forged pistons, rods).
2. Choose the Right Turbo Kit
- Research well-regarded brands and options (single or twin turbo).
- Ensure the kit fits your G37 model (coupe, sedan, RWD, AWD).
- Popular kits are available for both bolt-on simplicity and custom tuning flexibility.
3. Gather Supporting Mods
Even the best turbo kits need supporting modifications for optimal performance and reliability:
- Upgraded fuel injectors and high-flow fuel pump.
- Performance clutch or automatic transmission upgrades.
- Stronger spark plugs.
- Aftermarket intercooler (often included).
- Wider, stickier tires for improved traction.
4. Professional Installation vs. DIY
- Many turbo kits are bolt-on, but the job is rarely simple.
- Professional installation is highly recommended unless you have advanced mechanical and fabrication skills.
- Incorrect installation can lead to costly engine damage.
5. ECU Tuning
- Vital for safe and reliable performance.
- Professional dyno tuning ensures the air/fuel ratio is correct and maximizes power potential.
- Some kits include plug-and-play tuning solutions, but custom tuning is always best for maximum safety.
6. Test and Maintain
- After installation, start with low boost and monitor performance.
- Regularly check for oil leaks, boost leaks, and listen for abnormal sounds.
- Follow a strict oil change and maintenance schedule.
- Upgrade cooling systems if you plan to track or drive aggressively.
Benefits of Turbocharging Your G37
Wondering if all the effort is worth it? Here are some compelling reasons to boost your G37:
- Substantial Power Increases: Stock G37s make around 330 HP; turbo kits can push your car past 400, 500, or even higher horsepower.
- Improved Acceleration: Addicted to the feeling of being pinned to your seat? A turbocharged G37 delivers!
- Enhanced Driving Enjoyment: Turbo power brings a new level of excitement.
- Customization: Turbo kits let you fine-tune the experience for daily driving, drag racing, or road racing.
- Potential for Further Upgrades: Building a turbo platform opens doors to future performance modifications.
Challenges and Considerations (What to Watch Out For)
Turbocharging is a serious upgrade, and it’s important to be aware of some potential challenges:
1. Heat and Reliability
- Turbo engines run hotter. Upgrade your radiator and consider an oil cooler.
- Stick to a regular maintenance schedule to avoid premature wear.
2. Transmission and Drivetrain Stress
- The added torque can overwhelm stock components—consider beefing up your clutch, transmission, and even differential.
3. Cost
- Quality turbo kits and supporting mods aren’t cheap—budget for $5,000–$10,000+ including installation, tuning, and upgrades.
4. Emissions and Legality
- Many turbo kits are not emissions-legal in all states or countries. Always check local regulations.
- Some manufacturers offer CARB-legal versions for specific models.
5. Insurance
- Performance modifications can impact your insurance premiums and coverage.
- Always check with your provider before making major mods.
Top Turbo Kit Options for the G37
The G37 is well-supported by the aftermarket, with options for every budget and power goal. While there’s no need to name every brand, reputable manufacturers offer:
- Twin turbo kits with bulletproof hardware and proven power gains.
- Single turbo mid-mount kits for easier installation and great value.
- Rear-mount turbo kits, which can simplify packaging but may have longer boost lag.
- Complete packages that include tuning and all necessary hardware.
Before you buy, look for:
– Customer reviews and dyno results.
– Warranty and after-sales support.
– Compatibility with your exact G37 year, trim, and drivetrain.
Practical Tips for a Successful Turbo Build
Want your project to go smoothly? Keep these best practices in mind:
- Research, Research, Research: Learn from other G37 owners, read forums, and watch installation videos.
- Plan for Extra Costs: Expect surprises—such as worn hoses, belts, or additional labor.
- Don’t Cheap Out on Tuning: Professional ECU tuning is non-negotiable for turbo cars.
- Use Quality Oil: Turbo engines are hard on oil; use high-quality synthetic, and change it often.
- Monitor Key Sensors: An aftermarket boost gauge, wideband O2, and oil pressure gauge are great investments.
- Upgrade Brakes: More power means upgraded stopping power is a must.
- Start with Lower Boost: Dial in the car at safe boost levels before cranking it up.
Saving Money & Cost Tips
Turbocharging isn’t cheap, but you can avoid breaking the bank by:
- Bundling Supporting Mods: Some retailers offer packages including injectors, pumps, and tuning.
- Look for Sales and Promotions: Prices can vary widely—shop around.
- Check Shipping Policies: Kits may ship from different regions—factor in taxes, customs, and shipping fees.
- Used Kits: Good-quality used turbo kits come up for sale but always check for completeness and wear.
- DIY Where Appropriate: Confident wrenchers can save on labor costs. Still, don’t compromise on tuning quality or safety.
Maintaining a Turbocharged G37
A turbo G37 is a blast, but it demands more care. Here’s how to keep it running its best:
- Frequent Oil Changes: Turbos rely on fresh, clean oil.
- Cool Down Properly: After hard driving, idle the engine for a minute or two to prevent oil coking in the turbo.
- Inspect Components: Regularly check all turbo plumbing, clamps, and gaskets.
- Watch for Warning Signs: Smoke, strange noises, or loss of boost should not be ignored.
- Stick to High-Quality Parts: Don’t cut corners, especially on critical components like the fuel system or engine internals.
Common Mistakes to Avoid
- Skipping Tuning: Never run a turbo kit on a stock tune.
- Ignoring Supporting Mods: Fueling, cooling, and drivetrain upgrades are not optional.
- Over-Boosting: Running excessive boost on a stock engine is a recipe for disaster.
- Poor Quality Parts: Cheap knock-off kits often lead to headaches.
- Neglecting Maintenance: Small issues can become big problems quickly on a forced induction setup.
Wrapping Up
Turbocharging your G37 can transform it from a great daily driver into something truly special. Power, responsiveness, and an unforgettable driving experience are all within reach with the right approach. Take your time researching options, budget accurately, and prioritize safety and reliability alongside performance.
With some planning and respect for the process, you’ll soon enjoy a G37 that not only sounds amazing but leaves a lasting impression every time you hit the throttle.
Frequently Asked Questions (FAQs)
