4.8 SHORT STROKE HI TORQUE 240 – 245 BHP @ 5300 RPM, 285 – 290 FTLB @ 2700 RPM BASIC STRIPPED ENGINE
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 £ 6026.00
With CNC big valve upgrade £ 6672.00
