Essential Components for a Twin Turbo Build

Okay, you're sold on the idea. What do you actually need for a twin turbo build? Here's a rundown of the essential components:

  • Turbos: Obviously! Choose turbos that are appropriately sized for your engine and power goals. Garrett, BorgWarner, and Precision Turbo are popular brands.
  • Intercooler: This cools the compressed air from the turbos, increasing its density and further boosting power. A front-mount intercooler (FMIC) is a common choice.
  • Piping: You'll need custom piping to connect the turbos to the intercooler and intake manifold. Stainless steel or aluminum are common materials.
  • Wastegates: These regulate the amount of exhaust gas that bypasses the turbos, controlling boost levels. External wastegates are generally preferred for performance applications.
  • Blow-Off Valve (BOV): This releases excess pressure when you let off the throttle, preventing compressor surge and potential damage to the turbos.
  • Fuel System Upgrades: More power means more fuel! You'll likely need larger fuel injectors, a higher-flowing fuel pump, and possibly an upgraded fuel rail.
  • Engine Management System (EMS): A standalone EMS or a piggyback system allows you to properly tune the engine for the increased boost levels. Popular options include AEM, Haltech, and Hondata.
  • Gauges: Boost, air/fuel ratio, and oil pressure gauges are essential for monitoring engine performance and ensuring everything is running smoothly.
  • Exhaust System: A high-flowing exhaust system is crucial for reducing backpressure and maximizing power output. A cat-back or turbo-back system is recommended.
  • Reinforced Internals: Depending on your power goals, you may need to upgrade the engine's internals, such as the pistons, rods, and crankshaft, to handle the increased stress.
