2005-2019 Tacoma Engine Specs

2005-2019 Tacoma Engine Specs

The engine of your Tacoma is its heart and soul. It’s what defines it as an automobile. The nature of operation and modifications surround the engine entirely. It’s what provides you with heat, power, and forward motion. Without the engine, a Tacoma would simply be a hollow shell of a truck with little to no value. Regardless of the trim level or engine size, it’s worth taking the time to learn a thing or two about this operating system and how you can improve it.

Maintenance is simultaneously the worst and best aspect of owning a modified vehicle, Tacoma or not. Knowing when something is starting to go bad versus waiting for it to fail will not only prevent you from being stranded on the trails but also save on your wallet. Replacing worn out engine parts with either stock or aftermarket versions will keep your Tacoma around for the long haul.

Tacoma Engines

Over its lifespan, the Tacoma has arrived with three different engine sizes. The Toyota engines have always been top notch. Even their smaller platforms have been proven as stout, capable motors that work both on and off road.

The layout of the engine is crucial to understand if you’re about to dive into the engine and start making modifications. Establishing the baseline will give you an idea of how much power you are making, how much more you will need, and how to achieve it. 

2.7L 4- Cylinder: The smallest engine available in Toyota Tacoma’s is the 2.7-liter inline 4-cylinder engine –  a stout, fuel-efficient option. It may be thought of as an underdog in terms of power output, but these engines have been proven to hold their weight both on and off road.

  • Bore & Stroke: 3.74 in x 3.74 in
  • 185 horsepower @ 5800 RPM
  • 184 ft/lbs of torque @ 4200 RPM

3.5L V6: The 3.5-liter engine is the largest engine available to the Tacoma since the year 2016. This engine uses a large bore that’s combined with a relevant stroke size. Despite the smaller displacement, this engine is capable of producing a much higher output than the larger engines used in the years before.

  • Bore & Stroke: 3.7 in x 3.27 in
  • 295 horsepower @ 6600 RPM
  • 263 ft/lbs of torque @ 4700 RPM

4.0L V6: The 4.0L V6 engine is the largest engine to have ever arrived in the Toyota Tacoma. This motor uses a large bore with a long stroke to achieve its displacement. 4.0 liter Toyota engines are a favorite among crowds due proving its capabilities both on and off road. 

  • Bore & Stroke: 3.7 in x 3.74 in
  • 240 horsepower @ 5200 RPM
  • 278 ft/lbs of torque @ 3700 RPM

Common Mods

Toyota has always been an industry leader in terms of performance and durability. Its engines are excellent platforms that leave little to be desired by average drivers. For those looking to boost performance, Toyota engines are always excellent platforms to work on. They respond excellently to power adders and bolt-ons. If you’re looking to boost your Tacoma’s power output, there are routes you can follow that are proven to work.

Cold Air Intake: Dense air contains more oxygen and will help your Tacoma produce more power. Cold air intakes work to draw in as much cold air as possible to help increase horsepower, torque, and fuel economy. This type of modification is extremely cheap and requires very little time to perform. Popping one on your Tacoma is the first and easiest step you can take toward increasing performance.

Computer Programmer: The factory tune of your Tacoma is one that is meant to perform in street driven scenarios. It’s an economically friendly program that will help you produce decent power will reserving some in the name of fuel consumption. Programmers can upload tunes that are meant to increase power output. They don’t exactly add power they just unlock it. Programmers are reasonable on the cost scale, and you can upload tunes on demand from the comfort of your Tacoma’s cabin.

Supercharger: Allowing the engine to draw in air is one thing; forcing air in there is another. Superchargers are a common mod for Tacomas as the units dramatically increase power output. The addition of a supercharger is very expensive and time consuming. It may require professional techs in order to be installed properly but will result in the highest power increase of all typical mods.

Don’t Forget a Beefed Bottom End

Forced induction is hard on the bottom end. If you have too much power the pistons, connecting rods, and the crankshaft can take a serious beating. This is why you should consider beefing up the engines rotating assembly before throwing high amounts of boost at the bottom end. Boost also affects the compression of the fuel mixture and dished pistons may be required in order for the engine to operate correctly. 

Exhaust Systems: Getting air out of the engine is just as important as cramming it in. Bigger exhaust systems work to do more than just make the truck sound cool. Exhaust can escape the engine faster with high flow exhaust systems, which will help increase efficiency and power. High flow cats, bigger pipes, less restrictive mufflers, and good headers all work to help increase the flow of the exhaust. Wrapping the headers with heat wrap is another way to increase power. Keeping heat in the headers increases their ability to scavenge exhaust from the chambers which further improves power output.
