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.
