4BT LAND CRUISER CONVERSION
The team at ACD Engines has made 4BT conversions their specialty and had this 1992 Toyota Land Cruiser up on the rack while we were shooting photos of their new 4BT Stroker Kit. The owner of the Land Cruiser wanted more pep than the factory gas engine could offer, but didn’t want to sacrifice fuel mileage, making it the perfect candidate for a mildly upgraded 3.9L Cummins.
Knowing that major horsepower and torque would be needed and looking to keep things budget friendly, they opted for the less common and slightly cheaper VE injection pump series motor, versus the more popular and easily modified P7100 injection pump model. The VE pump working with custom ACD injectors and camshaft should bring power output up from the original 105 hp to a more user-friendly 200 hp. While this may not sound like much, the low-end torque of the 4BT backed by the NV4500 five-speed manual transmission (from the 1994-2001 Dodge Ram truck) will make for a great daily driver and off-road combination. On this particular build, ACD will also be able to retain the factory A/C and heating system, and were even able to add an intercooler system behind the grille. ACD and the vehicle’s owner are hoping this package nets a consistent 25-30 mpg. This 1992 Toyota Land Cruiser was on the rack while we were at ACD shooting photos of their 4BT Stoker kits; it’s already been converted over to a 4BT engine platform that uses one of ACD’S custom camshafts and reworked rotary VE injection pumps, which help pump power output from 130 hp to nearly 200 hp. The power and torque increase should be enough to move the Land Cruiser up and down the freeway with ease, while offering a good, usable power band while offroad and excellent fuel mileage while on-road. ACD Engines are experts at doing these 4BT conversions and have shoehorned the small Cummins engine into just about everything from Jeeps, mini-trucks and even a mid-’50s ambulance. Under the hood of this Land Cruiser you’ll notice that the four-cylinder diesel fits near perfect and will retain full use of the factory heat and A/C with some custom bracketry built by ACD. The addition of an intercooler in front of the radiator will also help with the turbo and engine’s efficiency. While you may think all the magic of this conversion is found under the hood of the Land Cruiser, ACD was right in the middle of installing the new transmission and transfer case. The mildly upgraded 4BT will be backed by the NV4500 five-speed manual transmission found in the 1994-2000 Dodge Ram trucks. The transfer case is also a one-off that with use of an adaptor ring allowed for a passenger-side tail shaft exit to allow proper driveline angles be kept with the Land Cruiser’s original front and rear axles.
