Brazilian Project Documented in Video Details How a Toyota Hilux Diesel Went from 204 HP to an Estimated Level Close to 400 HP, Combining Oversized Turbo, Nitrous System, Reinforced Injection, Suspension Adjustments, and Solutions Aimed at Drag Racing and Real Road Use
An extreme automotive preparation project caught attention in a recent video published by BFMS, presenting in detail a Toyota Hilux diesel transformed to achieve unusual power levels in the pickup segment.
The vehicle from the Hilux Project Brazil channel belongs to Danilo and features an oversized turbo, nitrous system, reinforced injection, and a series of mechanical and structural adjustments primarily aimed at drag racing.
The event, which was initially meant to be just an informal record of the truck, ended up becoming one of the most complete content pieces ever published about the project’s evolution.

Throughout the video, the presenters and the owner detail the main modifications, explain the technical choices, and show how the setup performs both stationary and in motion.
Original Base and Power Jump
The Hilux used as the base for the project leaves the factory with a diesel engine rated at 204 horsepower, already recognized for its robustness and durability. However, the goal was never to keep the truck close to the original configuration.
From the first interventions, the focus was on extracting performance far above the standard, without sacrificing the minimum reliability needed for real use.
With the current modifications, the estimate is around 300 horsepower at the wheels, which represents approximately 400 horsepower at the engine when considering transmission losses.
The figure has yet to be confirmed on a dynamometer, mainly because the chosen turbo has difficulty fully spooling in static conditions, but the street performance indicates that the goal has been achieved.
Giant Turbo and Custom Manifold
The heart of the preparation is in the new forced induction system. The Hilux received a significantly larger turbo than the original, with no variable geometry, installed on a custom-made manifold.
This manifold was specifically developed to accommodate the setup and optimize exhaust gas flow, an essential condition for feeding such a large turbo.
Unlike the original system, the new configuration uses an external wastegate valve, allowing greater control of working pressure at high RPMs.
All the pressurization was built from stainless steel, ensuring thermal resistance and durability, while the aluminum intercooler is responsible for reducing the temperature of the intake air before it enters the engine.
Nitrous System Applied to Diesel
One of the most unusual aspects of the project is the adoption of nitrous in a diesel engine. The truck features two nitrous injection points, used as a temporary power boost, especially in drag racing situations.
The main goal is to compensate for the time required for the giant turbo to reach full load, improving response at low RPMs.
According to the owner, there are other solutions aimed exclusively at drag racing that were not fully revealed in the video.
These choices reinforce the experimental and progressive character of the project, which continues to evolve.
Reinforced Fuel Supply and Modified High-Pressure Pump
To sustain the significant power increase, the fuel supply system also needed to be deeply altered.
The Hilux received fuel injectors with a flow approximately 50% greater than the originals, allowing for greater diesel delivery at high loads.
Additionally, the high-pressure pump had its internal shaft replaced, a modification that increases the volume of fuel delivered to the system.
In prepared diesel engines, this type of adjustment is crucial to avoid fuel shortages in extreme regimes and ensure that the combustion matches the volume of air supplied by the new turbo.
Suspension, Tires, and Chassis Adjustments
Performance on a straight line does not depend only on the engine. Therefore, the project also advanced on suspension, wheels, and tires.
The Hilux received a set of Ironman Foam Cell Pro 2.5, known for its behavior closer to competition suspensions than comfort.
The rear leaf spring was replaced and subsequently adjusted by removing load leaves, seeking a balance between height, traction, and comfort.
The final lift was set at about two inches, combined with 285/70 tires, which are smaller and lighter than those used previously.
The change reduced unsprung weight and improved both dynamic response and comfort in daily use.
Baja Visual and Structural Modifications
Visually, the truck follows a design inspired by Baja vehicles. The front bumper was cut to improve approach angle and reduce weight, but the finish received special attention. Instead of a simple cut, the assembly was internally reworked, maintaining a clean and functional appearance.
The result is a Hilux with an aggressive look, consistent with the mechanical proposal, but without an improvised appearance. The wheels, the lifted suspension, and the external details reinforce the identity of a project designed for extreme use.
Transmission, Cooling, and Instrumentation
With elevated power, the automatic transmission also required additional care. The project includes an auxiliary transmission oil cooler, responsible for controlling temperature in drag racing situations, when the torque converter is highly stressed.
Inside, the Hilux received additional instrumentation, including a display that monitors engine temperature and air-fuel mixture.
This data is essential for fine-tuning adjustments and preserving the mechanical setup during intense use.
Real Use and Project Philosophy
Despite its level of preparation, the truck is not restricted to events or tracks. The video itself shows that it is used for long trips, including a journey of approximately one thousand kilometers between Campo Grande and São Paulo.
Maintaining a cruising speed close to 120 km/h, the recorded fuel consumption was around 7.5 km per liter, a number considered acceptable within the proposal.
