The 4.5L engine is a 4 cylinder, 107mm bore, 124mm stroke with a 16 valve head and central vertical injection. As well as being a turbo charged, high pressure common rail engine with a 17.3:1 compression ration and no glow plugs, it’s main design is based on the modern 6.7L truck engine that you can find in a Dodge RAM.
From the head down, the design is the norm for modern, medium diesels with 4 valves per cylinder and the injector mounted centrally and vertically, compared to the old 4BT and 6BT which use side injection and an off centre piston bowl.
The 24 valve heads are a cut down version of a model known for their excellent coolant flow and heat exchange capabilities throughout their power range, owing to optimal coolant gallery design.
As the pistons, conrods and most other internal parts are from the 6.7L with rated standard torque of 1100nm, there is more than adequate built in strength present to keep it all running smoothly up to 400hp, without the need for modification.
The cam and aux drive is via a geared drive train at the rear of the engine that drives the cam, fuel pump and accessory gear, as the timing gears are sandwiched between the rear of the block and the front of the alloy adaptor plate, this reduces timing gear noise vastly compared to the old front gears of the B-series using a tin cover that essentially acted as an acoustic amplifier.
Expected economy range in your average Toyota or Nissan set up to tour the country us about 10-12L/100KM up to 14L/100km depending on your individual set up, regardless these figured will be much better than late model V8 Landcruisers or standard engines like the ZD30, TD42, 1HZ etc with the identical set up.
We have over 12 months of development in custom software allowing us to completely retune the factory Cummins ECU, and are the only representative outside of Cummins that is able to make changes to fuelling and max RPM. Factory RPM is 2800RPM, Cummins list 4250RPM as the maximum, and we generally set them to be around 3500-3700RPM.
Being the original innovator of the Cummins 4.5L Conversion into Patrols and Landcruisers, we have adaptor plates ready to go, to bolt these weapon engines up to standard Patrol 5SP manual gearboxes, standard RE4 Patrol automatic transmissions and also Toyota H151 manual gearboxes.
