   • Manifold Selection: A tubular exhaust manifold enhances exhaust flow, improving spool and overall efficiency.
   • Boost Targets: Aim for 25–30 PSI of boost to achieve 1,000 HP with proper supporting modifications.
2. Fuel System
   • High-Flow Fuel Injectors: Replace the factory injectors with units capable of flowing at least 1,200 cc/min to handle the increased fuel demand.
   • Upgraded Fuel Pump: Use dual in-tank or external fuel pumps (e.g., Walbro 525 or Bosch 044).
   • Fuel Lines and Regulator: Reinforce fuel lines and use an adjustable fuel pressure regulator for precise control.
3. Engine Internals
   • Forged Pistons and Rods: Replace stock pistons and rods with forged alternatives (e.g., CP Pistons, Carrillo rods) for higher compression and durability.
   • Crankshaft Reinforcement: Although the stock crankshaft is robust, balancing and nitriding enhance its strength for extreme builds.
   • Head Gasket and Studs: Upgrade to a multi-layer steel (MLS) gasket and ARP head studs to prevent failures under high boost.
4. Standalone ECU
   • Programmable Engine Control: A standalone ECU (e.g., AEM Infinity, Haltech Elite) allows precise control of fuel delivery, ignition timing, and boost levels.
   • Tuning Expertise: A professional tuner is essential to optimize performance while maintaining engine safety.
5. Cooling System
   • Larger Intercooler: An upgraded intercooler ensures cooler intake air temperatures, increasing combustion efficiency and reducing detonation risk.
   • Oil Cooling: Install an external oil cooler to manage higher engine temperatures during prolonged high-power operation.
