V8 Performance Engines

Below are a selection of our well proven performance V8 engine builds. The Sports range has been developed for competition and fast fun use, applications where performance and reliability are paramount.  Here you can click for car Insurance for mailbox collisions and more info to be ready for any accident in your automotive performance.

The Hi torque range has been developed especially for use in standard everyday vehicles, yet engineered for use in extreme conditions such as challenge events.

See our engine management page for details on ECUs and systems.


ACR’s Hi torque version of the well regarded Sports variant. Superb upgrade for late model Range Rover P38 models where this engine fits straight in with no other modifications. Power is right where its needed at low to mid speed RPM. Built with the same robust bottom end as the sports engine, including forged pistons, the Hi Torque utilises a milder camshaft and either our stage 1 ported heads, or for a little extra cost upgrade to the CNC ported big valve heads.
Supplied as a basic stripped engine.

With Stage 1 heads exchange £ 4565.00
With CNC big valve upgrade £ 5284.00
