Engine - 2.5L Duratec
The 2.5L Duratec engine is of all aluminum construction with a 2-piece cylinder block made by a special casting process.
The 2.5 liter 24 valve V6 engine has an electrical controlled lower intake manifold switching system to optimize torque and power output.
The four overhead camshafts are driven by two timing chains. The engine incorporates the latest engineering: electronic engine management with Distributorless Ignition (EI) System, sequential electronic fuel injection, electronically controlled exhaust gas recirculation and two catalytic converters in the exhaust manifolds.
The Cougar includes the following power upgrades;
^ Extrude honed secondary cylinder head intake ports.
^ Extrude honed upper and lower intake manifolds.
^ Larger 60 mm throttle body.
^ New intake and exhaust camshafts with revised valve timing.
^ Compression ratio is increased to 10:1.
^ Low restriction air inlet using a conical filter element.
^ Large diameter low restriction exhaust system with dual outlets.
