Whereas
the Patrol makes do with old pushrod-actuated overhead valve technology,
the Cruiser has double-overhead cams and four valves per cylinder, and
pumps out an impressive 165 kW at 4600 rpm and 387 Nm at 3600 rpm. Performance
is good and the big six offers the best fuel economy in its class as well.
But for people who want more, Safari 4X4
Engineering has the answer in the form of an intercooled turbo kit for
the big petrol six that will leave Toyota’s own GXV well and truly in its
wake.
The kit itself consists of a water-cooled
turbocharger, a cast alloy cross-over manifold a two piece exhaust manifold,
an intercooler and a Unichip engine management system. All plumbing
consists of teflon-lined water and oil lines.
Thanks in part to the Unichip engine management
system, Safari has been able to tune the engine to develop peak power and
torque at lower revs than the standard engine for better drivability.
The end result is a claimed 230 kW at 4200 rpm and 535 Nm at 3200 rpm.
Unlike turbocharged petrol engines of old,
the Safari Landcruiser loses none of its low rpm torque, making it easy
to drive around town with immediate engine response right from idle.
In the past it was necessary to lower the compression ration of turbocharged
engines to prevent detonation when on boost, but thanks to electronic engine
management and knock senors this is no longer the case, so the Safari Cruiser
works just as well off-boost as a standard cruiser. It is however
recommended that the Safari Cruiser be run on premium-grade unleaded fuel.
