Fuel Injection System in the V35A-FTS Engine – V35A-FTS D-4S injection system
V35A-FTS Engine Fuel Injection System – Experience the Power of Toyota’s Groundbreaking D-4S Injection Technology
Are you on the lookout for a tough, strong, and technology-based engine for your project build or engine swap? If so, then the V35A-FTS engine with Toyota’s innovative D-4S fuel injection system might be just what you require. In this über comprehensive guide, we’re breaking it all down to get you current on just what you must know about the V35A-FTS engine, its advanced fuel injection system, its performance aspects, and why it’s among the smartest choices for tuners, enthusiasts, and pro fabricators.
Spoiler alert: Yes, we actually do offer the V35A-FTS engine – read on to discover why it’s the smartest investment.
1. Introduction to the V35A-FTS Engine
The V35A-FTS is the twin-turbo 3.5-liter V6 from Toyota that first appeared in the 2018 Lexus LS500 and later was also seen in other Toyota and Lexus high-performance vehicles. It’s a backflip for Toyota’s engineering department — unification of turbocharging with the D-4S direct and port fuel injection system for both maximum power and efficiency.

This engine is part of the Dynamic Force Engine series of engines, which are known for providing excellent fuel economy, low emissions, and plain old-fashioned power. Whether you’re building or rebuilding a high-end project car, the V35A-FTS has the strength, technology, and durability you need. V35A-FTS D-4S injection system
2. What is D-4S Fuel Injection?
Toyota’s own dual-injection system is known as the D-4S fuel injection system. D-4S is an acronym that refers to Direct-injection 4-stroke Superior — and, as it happens, that’s not a bad description.
It Employs Two Systems:
- Direct Fuel Injection (DI): Directly injects fuel into the combustion chamber for precision and efficiency.
- Port Fuel Injection (PFI): Fuel injectors spray fuel into intake ports, to the benefit of low-load efficiency and protection of intake valve clogging.
The system uses both the injection forms alternately or together, depending on the driving conditions. It changes mode cleverly to provide:
- Enhanced fuel economy
- Less emissions
- Additional power and torque
- Smoother engine operation
It is the same technology that makes Lexus and Toyota engines drive so well under normal and stiff accelerating.
3. How the D-4S System Functions in the V35A-FTS
The V35A-FTS has a performance-tuned D-4S system. This is what it does in real time:
- At low load and RPM, the engine relies heavily on port injection for better fuel atomization and more refinement of combustion.
- At moderate load, port injection and direct injection are employed to maximize efficiency and performance.
- Under high load or high boost, direct injection is employed such that there is more control over combustion and less knocking.
Combined with twin turbochargers, intercoolers, and electronic throttle control by way of advanced electronics, the D-4S system gives this engine an excellent response and breathtaking torque across the powerband.
4. V35A-FTS Engine Specifications
Following are the major specifications of the Toyota V35A-FTS engine:
| Specification | Details |
|---|---|
| Engine Code | V35A-FTS |
| Configuration | V6 Twin-Turbo |
| Displacement | 3.5L (3,445 cc) |
| Fuel System | D-4S (Direct + Port Injection) |
| Bore x Stroke | 85.5 mm × 100 mm |
| Compression Ratio | 10.5:1 |
| Turbochargers | Twin single-scroll |
| Max Power Output | ~416 hp (310 kW) @ 5200–6000 rpm |
| Max Torque | ~600 Nm (442 lb-ft) @ 1600–4800 rpm |
| Redline | ~6600 rpm |
| Fuel Type | Premium Gasoline |
| Emission Std. | Ultra Low Emission Vehicle (ULEV) |
Specifications differ by a hair here and there depending on the application employed (Lexus LS500, Tundra, Sequoia), but the overall architecture remains the same.
5. V35A-FTS Performance Advantage
The V35A-FTS is not merely a set of numbers — it’s how it produces power differently compared to other engines. Here’s how:
✅ Torque-On-Demand
Twin turbos and exhaust manifold tuned, torque is early — 1600 RPM — and flat across the rev range.
✅ Fuel Efficiency
D-4S system and high compression ratio, it pulls the performance-fuel saving trick off in concert, especially when cruising.
✅ Turbo Response
Low turbo lag with short runner concepts and downsized turbos.
✅ Tuning Potential
Aftermarket support is growing fast. With proper ECU tuning and supporting mods, this engine has great potential for 500+ HP builds.
6. Why Choose the V35A-FTS for Your Project?
You’re not just buying an engine — you’re investing in a modern performance platform with:
- Advanced engineering
- Lightweight aluminum block
- Built-in longevity and efficiency
- Exceptional power-to-weight ratio
- Easy integration with Toyota/Lexus ECUs
Whether you’re building a drift car, a sleeper, or a high-end street machine, the V35A-FTS delivers a mix of modern reliability and thrilling power.
7. Applications: Where the V35A-FTS Shines
This engine is already powering some of Toyota’s top-tier models:
- Lexus LS500 – Luxury sedan with sports car performance
- Toyota Tundra (new gen) – Full-size truck needing torque and towing power
- Toyota Sequoia – Full-size SUV with hybrid-assisted V35A
- Lexus LX600 – Off-road capability and performance in one
For project builders, it’s the ideal match for:
- Engine swaps in older Lexus or Toyota models (such as IS300, Supra, or Land Cruiser)
- Restomod installations
- Custom builds in which turbo V6 response and torque are required
8. V35A-FTS vs Other Turbo V6 Engines
This is how it compares to the competition:
