b-series turbo kit

To build a 600hp B-Series turbo setup, you’ll need a carefully chosen combination of high-quality parts, strong engine internals, and precision tuning. A 600hp goal is considered high-performance, and achieving it reliably on a B16, B18, or B20 engine requires reinforcing the engine, selecting the right turbo components, and ensuring all supporting systems (fuel, cooling, and drivetrain) are up to the task.

Key Components for a B-Series Turbo kit Build

1. Engine Internals (Forged and Reinforced Parts)

• Forged Pistons: High-performance forged pistons (e.g., CP Pistons, JE Pistons) are required to handle the extreme cylinder pressures of 600hp. They also allow for higher boost levels without risking failure.
• Forged Connecting Rods: Reinforced rods, like those from Eagle, Carrillo, or Manley, are essential for supporting the increased power and higher RPMs typical in a turbo setup.
• Upgraded Bearings: High-quality main and rod bearings (e.g., ACL, King Racing) are important to ensure the engine can handle the added stress.
• Upgraded Head Gasket and ARP Head Studs: A MLS (multi-layer steel) head gasket and ARP head studs are necessary to maintain a strong seal between the head and the block at high boost levels.

2. Turbocharger

• A large turbocharger capable of moving enough air for 600hp is essential. Common turbo choices for this power level include:
  • Precision 6266: Known for its efficiency and ability to handle high boost pressure, this turbo is popular in 600hp builds.
  • Garrett GTX3582R: Another excellent choice, providing good spool characteristics while supporting up to and beyond 600hp.
  • BorgWarner EFR 8374: Offers strong performance across the RPM range with modern turbo technology.
• Make sure to choose a T3/T4 flange turbo manifold capable of supporting a larger turbo with good exhaust flow.

3. Turbo Manifold

• A high-flow turbo manifold designed to maximize performance is necessary. Ramhorn-style manifolds are popular for high-horsepower builds due to their ability to promote better flow and reduce backpressure.
• Consider high-quality brands like Full-Race, PeakBoost, or Go-Autoworks for your manifold.

4. Intercooler and Piping

• A large front-mount intercooler (FMIC) is required to cool the compressed air from the turbo, which helps prevent detonation and maintains power. Choose a large-core intercooler that can support 600hp, like those from Mishimoto or Treadstone.
• Ensure all intercooler piping is properly sized (typically 2.5 to 3 inches) and made from materials like aluminum or stainless steel.

5. Fuel System Upgrades

• High-Flow Fuel Injectors: For a 600hp build, you’ll need 1,000cc injectors or larger, depending on fuel type. If using E85, even larger injectors like 1,300cc or 1,600cc may be necessary (brands like Injector Dynamics or DeatschWerks).
• High-Flow Fuel Pump: A fuel pump capable of delivering enough fuel at high pressure is critical. The Walbro 450 or AEM 340LPH are common choices, but for E85, consider dual fuel pumps or a larger Bosch 044 pump.
• Fuel Pressure Regulator: An adjustable fuel pressure regulator helps maintain the correct fuel pressure, especially under boost.

6. Engine Management System (ECU)

• To safely tune a turbocharged engine to 600hp, you’ll need a standalone or programmable ECU like Hondata S300, AEM EMS, or Neptune RTP. These systems allow for precise control over fuel, ignition timing, and boost levels to ensure the engine performs reliably under high loads.
• Dyno tuning is essential to ensure proper air-fuel ratios and to avoid engine-damaging detonation.

7. Wastegate and Boost Control

• A high-quality external wastegate (such as Tial or Precision 44mm or larger) is needed to control boost pressure effectively. Boost creep can be an issue in high-horsepower setups, so proper wastegate sizing is important.
• Consider a boost controller (electronic or manual) to dial in your desired boost levels. Electronic controllers, like those from AEM or Grimmspeed, allow for precise adjustment and in-car tuning.

8. Exhaust System

• A 3-inch exhaust system is recommended for a 600hp build to minimize backpressure and maximize flow. A turbo downpipe (3-inch or larger) and a free-flowing exhaust will help the turbo perform at its best.

9. Blow-Off Valve (BOV)

• A high-performance blow-off valve is essential for releasing excess boost pressure when you lift off the throttle, preventing compressor surge. Brands like HKS, Tial, or Greddy offer reliable options.

10. Transmission and Drivetrain Upgrades

• Clutch: At 600hp, a high-performance clutch like the ACT Extreme Duty, Competition Clutch Stage 4, or Exedy Twin-Disc is necessary to handle the power without slipping.
• Transmission Gears: Stock B-Series transmissions may not hold up under 600hp, so you might need to upgrade to strengthened gear sets from brands like MFactory or Gear-X.
• Limited-Slip Differential (LSD): To ensure power is delivered evenly to the wheels, especially in a front-wheel-drive application, an LSD is crucial for traction. Brands like Quaife and MFactory offer excellent LSDs for B-Series transmissions.

11. Cooling System

• Upgraded Radiator: A high-capacity aluminum radiator (such as Mishimoto or Koyo) is needed to keep engine temperatures in check under high boost.
• Oil Cooler: Adding an external oil cooler helps manage oil temperatures, which can rise significantly under turbo conditions.

12. Brakes and Suspension

• Brake Upgrades: With 600hp, upgrading your brake system is essential. Consider larger rotors, performance pads, and high-performance brake kits from brands like Wilwood, Brembo, or StopTech.
• Suspension: To handle the extra power, upgrade your suspension with coilovers, sway bars, and bushings from brands like Tein, BC Racing, or KW Suspension.
