Engine (03.00)
Engine Assembly (03.00)
Description
The engine is an all aluminium 4.3 litre 90° V8 configuration. The cylinder heads have dual
overhead camshafts and four valves per cylinder. An electronic engine management system
controls the sequential multi-port fuel injection and distributor-less ignition systems.
The engine uses the latest ‘fast-burn’ combustion technology. Heated oxygen sensors monitor the
oxygen content of exhaust gasses . The engine management system uses the oxygen sensor signals
together with other engine information to ‘fine tune ’ fuelling levels and ignition timing. This helps
to achieve the best possible fuel bur n with minimum exhaust emissions.
Inlet camshaft variable timing to impr ove engine performance and emissions.
Inlet manifold is design with tuned length runners to improve volumetric efficiency and
performance.
The engine is fitted with a dry sump to improv e oil pickup during high speed cornering.
The exhaust system has hydroforme d internals with a 4 into 2 into 1 design for improved engine
tuning and lower backpressure. Additional oxygen sensors are placed after the catalysts so that
long term catalyst efficiency can be monitored.
The engine runs on unleaded fuel only.

Engine Structure (03.01)
Issue 4, November 2008Workshop Manual 3-1-3
Knock Sensors
Two knock sensors (1) are installed into the cylinder block on the inboard side of each of the two cylinder banks. The
electrical connector of each sensor is secured to th e left-hand engine cover bracket (Refer to Figure 4).
These piezo-electric sensors send inputs to the ECM to indicate the detection and location of detonation during
combustion.
Bedplate
This is a structural casting that is attached with bolts to the bottom
of the cylinder block t attach the crankshaft and to further
improve overall rigidity.
Main bearing clearance changes due to expansion are minimized
by means of iron inserts cast into the bedplate main bearing
supports.
Two hollow dowels align the bedplate with the cylinder block and
the joint is sealed by a continuous bead of sealant.

Engine Mountings
The engine is mounted at two points. At the front, on ea ch side of the engine, there is a mounting bracket with a
Hydramount mounted to the subframe.
