Thread: cummins B3.3t into Range Rover

Cummins run the intake and the exhaust on opposite sides to say an Isuzu 4BD1T.
So while the Isuzu is a tight fit, the cummins will be a battle between having a steering box and a turbo with exhaust fitted.

The torque curve on the cummins also plummets pretty quick, hence peak power around 2600rpm.
It'll be a trickier swap than the average Isuzu or landrover engine. But doable.

Have you considered the max. revs and the torque curve, this engine may not be suitable for use on or off road, if it doesn't have similar or same torque curve and RPM range as a 300TDi then you may have to alter final drive ratios to maintain highway speeds and that could bugger up the torque curve, Regards Frank.
