The 4P Stage 3 engine offers more power and rpm capability over an OEM engine configuration through 120+CFM improvements in the cylinder head and a race developed 4P Camshaft. Expect 50+hp gains over the OEM engine with an equal turbocharger, and where the stock engine leans over before redline, this engine keeps building power and acceleration. Durability is increased with stronger components, allowing larger turbos to be used up to 800+hp.
