Diesel vs Gasoline Engines

The debate between a Diesel or Gasoline powered vehicle really depends on driving style. Most off-road capable Land Rovers usually opt for a diesel power plant. Why? Diesel engines typically have less electrical components, can operate under water better (when fitted with a raised air intake) and reach their maximum torque output at low RPMs which is great for slow speed off-road driving. Diesels typically take a bit less maintenance over time. They have less cylinders, usually around 4 in-line. They also return a much higher fuel efficiency which is also great when you are hundreds of miles away from a fueling station. Gasoline engines are more geared toward highway driving, and long hours in the truck where quicker speeds are needed. These engines tend to run quieter than diesels. They have a lot more electric components and with a V8 they have two banks of cylinders on the right and left side, spark plugs and a more complex injection system than a Diesel

our engine recommendations

Here at Brooklyn Coachworks we have driven all different engines and have a good understand of which engine will suit your driving style best. For diesel power we prefer the Cummins R2.8 engine because its both modern, powerful and efficient. The specifications on this newly release Cummins engine are spot on for any vintage Land Rover. The Cummins R2.8 is small and lightweight, produces 161 horsepower and 310 foot pounds of torque which makes this engine a beast for such a small 4 cylinder engine. You should also see 26/28 miles per gallon in return. Our second diesel engine pick goes to the 200Tdi & 300Tdi Land Rover engine. Build in the 90’s these engines have proven to be very reliable if set up correctly. Their output is moderate with around 110 - 120 horsepower and 200 - 220 foot pounds of torque. Maintenance on these 200Tdi & 300Tdi engines are simple and cheap. Our favorite Gasoline engine is the Chevy LS line which provides modern day engineering and quality. These engines will last forever and deliver incredible power and torque over any V8 out there. Your miles per gallon will slightly improve over a Land Rover V8 but not by much as most V8’s are thirsty.

Land Rover Diesel Engines

Land Rover are known to have build some quality small diesel engines. Low in horsepower and torque these engines are reliably if looked after properly and set up right. Brooklyn Coachworks has been tuning diesel engines for a long time now and have done all the proper steps and modifications to ensure you get the most out of your engine. Our 200tdi & 300tdi engines have boost pin modifications done, our advance timing is set up perfectly and we run a respected 10psi (200tdi) and 18/20psi (300tdi) turbo boost. We can also fit larger intercoolers to help compress colder air flow into your intake system for greater combustion. We also fit VGT (Variable-Geometry Turbochargers, also known as Variable Nozzle Turbines/VNT) turbos which help produce the max recommended boost at lower RPMs so that turbo lag is all but eliminated.

Land Rover Gasoline Engines

The Land Rover V8 was derived from a General Motors Buick 215, an all-aluminium OHV pushrod engine introduced in 1960. This gasoline engine was used in North American Spec Defenders, Discovery and Range Rover models from early 1970s to 2004. It came in various sizes from 3.5, 3.9/4.0, 4.2 and 4.6 liter engines. While still a V8 the output and torque ratings on these engines were just adequate to run a stock Land Rover, they have becomes tired over the years and their 12 city / 15 highway mile per gallon ratings are not very impressive. Parts are readily available but diagnosing them can be troublesome at times. Some engines can suffer from cooling issues and head gasket problems but we see those more or less in the later 4.6 engines. Sensors and electrics on these engines are also dated.

Engine Specifications

Land rover 3.5l - 158 hp @ 5,200 rpm / 210 lbfft @ 2,600 rpm

Land rover 3.9/4.0l - 188 hp @ 4,750 rpm / 250 lbfft @ 2,600 rpm

Cummins Diesel Engines

Brooklyn Coachworks is the premier Cummins R2.8 engine conversion builder. We take the new Cummins R2.8, 50-State EPA Certified (soon to be CARB - California Air Resources Board legal) diesel crate engine with 161 horsepower and 310 lb-ft of torque and fit it seamlessly into your vintage Land Rover. We fit it to an upgraded heavy duty Land Rover transmission and transfer case to ensure the driveline will handle this new amount of torque. These engines revolutionize your vintage Land Rover Series and Defender into a much more pleasant driving experience on-road and off-road. You are able to overtake other drivers on the highway and still return an impressive 26/28mpg. The Cummins R2.8 also comes with an ODB-II port so we are able to plug it in to figure out any problems or update the software like any other modern car.

Chevrolet performance Gasoline Engines

Chevrolet is known as one of the best engine builders in the United States. their famed LS line of crate engines are very well made and produce incredible horsepower and torque for such a small lightweight V8 engine. This LS engine comes in a variety of horsepower and torque specs so getting the right engine is easy to tailor for you. We tend to steer customers away from the massive LS3 as it can be a bit overkill for the Land Rover Defender. Remember these are trucks with a high center of gravity and with solid axles and no ABS, air-bags or traction control. So driving a 600 horsepower Defender can get scary very fast. We want you to enjoy the drivability of your Defender and also get great fuel economy from your gasoline powered Chevrolet V8 and trust us when we say their are way more fun at slower sleeps.

Engine Specifications

Chevrolet L96 - 360 hp @ 4,500 rpm / 380 lbfft @ 4,200 rpm

Chevrolet L99 - 400 hp @ 4,500 rpm / 410 lbfft @ 4,200 rpm

Chevrolet Ls3 - 525 HP @ 6300 RPM, 489 lbfft @ 4,400 RPM
