TORQUE SPECIFICATIONS CHART

The 3.0L (4V) (182 CID) is a 60-degree V-6 engine with dual overhead camshafts (DOHC), 4 valves per cylinder and sequential multiport fuel injection (SFI). The engine has

  1. An aluminum upper intake manifold.
  2. A lower intake manifold.
  3. Aluminum cylinder heads.
  4. A cast aluminum upper cylinder block.

The ignition system is electronic (distributorless) with a single ignition coil located above each spark plug. This high-energy ignition system is required for fast-burn combustion.

A unique 3-stage intake air system that utilizes 2 separate plenums, one for each side of the engine. The plenums can be connected through the operation of 2 special intake manifold tuning (IMT) valves to improve upper RPM power.
