How the V35A‑FTS Engine Compares to the 2UR‑GSE and Other Toyota V8s

If you’re shopping for a high-performance engine, or considering an upgrade, you’ve likely come across Toyota’s V35A‑FTS engine and the venerable 2UR‑GSE V8. In this in-depth comparison, we’re going to break down how the V35A‑FTS stacks up — against the 2UR‑GSE and other Toyota V‑series engines — in terms of specs, performance, efficiency, reliability, and real-world usability. Along the way, we will also demonstrate how and why you may want to purchase these engines (yes, we sell them) and which one is appropriate for your application. 35A-FTS vs 2UR-GSE

1. Engine Design & Underlying Philosophy

V35A‑FTS: New Generation Twin‑Turbo V6

Toyota’s new 3.5 liter twin‑turbo V6 engine, the V35A‑FTS, has been created to deliver V8-level power with higher efficiency and weight savings. 35A-FTS vs 2UR-GSE

Key design features:

  • Displacement: ~3444 cc (3.444 L)
  • Bore × Stroke: 85.5 mm × 100 mm
  • Compression Ratio: ~10.5:1
  • Forced Induction: Twin turbochargers with intercooler
  • Valve train & timing: DOHC, VVT‑iE + VVT‑i (i.e. electrically controlled intake cam timing + conventional variable timing)
  • Injection system: Direct injection (D‑4ST / D‑4S style)
  • Engine block & heads: Aluminum construction for weight saving

Toyota’s intention with V35A‑FTS was to create a “downsized” engine with V8 power and torque levels, yet improved fuel economy, lower emissions, and lighter weight.

2UR‑GSE: The High-Revving Naturally Aspirated V8

2UR‑GSE is a naturally aspirated 5.0 L V8 that is used in Lexus performance models such as the IS F, RC F, LC 500, GS F, and more. 35A-FTS vs 2UR-GSE

Key specifications:

  • Displacement: 4969 cc (5.0 L)
  • Bore × Stroke: 94 mm × 89.5 mm
  • Compression Ratio: 11.8:1 to 12.3:1 (dependent on version)
  • Valvetrain: DOHC, 32 valves, Dual VVT‑i with VVT‑iE on intake in some versions
  • Fuel System: Toyota’s D‑4S (direct + port injection)
  • Materials: Aluminum block and heads

2UR‑GSE is designed for naturally aspirated performance, with wonderful sound, very high engine speed, and more traditional “sports car” feel, compared to forced induction torque. 35A-FTS vs 2UR-GSE

2. Performance: Power & Torque Comparison

Let’s cut to the chase and compare the performance of those two motors and what that implies for driving.

V35A‑FTS Performance Numbers

Depending on application and market tune, the V35A‑FTS is able to:

  • Power: ~350 to 420 hp (tuning and application dependent)
  • Torque: ~550 to 650 Nm (peak)
  • Engine Weight: ~182 kg
  • Efficiency: The V35A‑FTS is part of Toyota’s “Dynamic Force” line of engines with ~37% thermal efficiency in some models.

Tuning and variant-specific modifications in real life will affect numbers (i.e., on trucks such as the Tundra or Land Cruiser). E.g., in Land Cruiser J300, the V35A‑FTS delivers ~415 hp and 650 Nm torque.

2UR‑GSE Performance Figures

The 2UR‑GSE offers:

  • Power: ~416 to 467 hp in different tuning versions
  • Torque: ~503 to 540 Nm (few models)
  • Revs: Redline is typically ~7,100 rpm (some older models lower)
  • Weight: ~224 kg dry

In short, the V35A‑FTS loses a bit of its high-end power but gains a whole lot of torque (especially at low rpm) under forced induction. The 2UR‑GSE, conversely, takes it best at higher revs with that familiar V8 throttle sound and powerband. 35A-FTS vs 2UR-GSE

Side-by-Side Spec Comparison

SpecificationV35A‑FTS (Twin Turbo V6)2UR‑GSE (Naturally Aspirated V8)
Displacement~3444 cc4969 cc
Forced InductionTwin-turboNone (naturally aspirated)
Peak Power~350 to 420 hp~416 to 467 hp
Peak Torque~550 to 650 Nm~503 to 540 Nm
Weight (Dry)~182 kg~224 kg
Compression Ratio~10.5:111.8:1 to 12.3:1
Redline / Peak RevMore conservative RPM bandHigh revving, ~7,100 rpm
Thermal Efficiency~37%Lower overall (naturally aspirated)
Torque DeliveryStrong at low-mid rpm (boosted)Linear and rising with rpm

So, under most real-world scenarios, the V35A‑FTS will be more responsive and willing at low rpm (especially under load) and the 2UR‑GSE will be all about higher rpm and imparting that V8 vibe. 35A-FTS vs 2UR-GSE

3. Efficiency, Emissions & Practical Useability

Fuel Efficiency & Emissions

As V35A‑FTS is turbocharged and downsized, it will use less fuel in low loads than enormous naturally aspirated V8s.

Boiler direct injection efficiency, latest variable timing, and act to reduce pumping losses and emissions.

Toyota’s V35A‑FTS is part of Dynamic Force engine lineup with industry-mentioned 37% thermal efficiency in some models.

Additionally, Toyota also features electric wastegate control of turbos (in a bid to reduce boosting lag and pumping losses) in some models.

In return, V8s like the 2UR‑GSE experience increased fuel consumption, especially under part-load, as a result of their inherently larger displacement and frictional losses. 35A-FTS vs 2UR-GSE

Thus, for everyday driving or mixed driving, the V35A‑FTS can deliver better economy (yet still deliver V8-like torque when needed).

Heat, Packaging, and Weight

The lighter and smaller V35A‑FTS benefits from packaging, weight distribution, and center-of-gravity, which improves handling and chassis balance.

Forced induction, however, requires cooling systems, intercoolers, and thermal management, adding complexity.

The 2UR‑GSE is less complex (no turbo plumbing) and stronger from a cooling stand point in some applications, although heavier and larger. 35A-FTS vs 2UR-GSE

4. Reliability, Durability & Common Issues

When investing in a performance engine, how long it will last—and under what conditions—matters. Let’s compare what’s out there.

V35A‑FTS: Potentials and Risks

Pros:

  • New-age engineering, with Toyota’s newest materials and design.
  • Advantage of forced induction (assuming well-maintained and well-tuned) to enable reduced engine stress at a given power rating. 35A-FTS vs 2UR-GSE
  • Since it’s a newer platform, Toyota has more advanced manufacturing and control systems.

Cons / Known Problems:

  • A few instances of main bearing failure on certain 2022–2024 models with V35A‑FTS (especially heavy duty or irresponsible maintenance).
  • Others propose that oil change interval and oil quality are paramount; dawdling or below-par oil can cause failure.
  • Because it’s a turbocharged engine, turbo, boost control, heat soak, or inefficiencies in inter-coolers might place too much pressure on an NA engine.

In brief: The V35A‑FTS is good, but needs strict maintenance, high-quality oil, and delicate tuning. Its state-of-the-art performance is a worthwhile compromise for most consumers. 35A-FTS vs 2UR-GSE

2UR‑GSE: Tried and Tested

Pros:

  • The 2UR-GSE has been built for decades in many Lexus models and has a proven record.
  • Simpler design (no turbos) would typically equate to fewer parts under high stress, and hence fewer turbo-related modes of failure.
  • Owners also bring with them high mileage with excellent maintenance.

Advantages:

  • Wear is a problem at high rpm, or under heavy use (as in most high-performance engines).
  • Fuel economy is poorer, and running costs (friction, etc.) could be higher.

Overall, for long-term reliability, a properly maintained 2UR‑GSE is a better bet. But for those who require cutting-edge performance, V35A‑FTS could be the trade-off. 35A-FTS vs 2UR-GSE

5. Use Cases, Swap Viability & Buyer Considerations

Use Cases & Applications

Luxury / SUV / Truck Use: V35A‑FTS is presently used in vehicles like the Land Cruiser J300, Lexus LX600, Tundra, etc.

Sport / Performance Cars: 2UR‑GSE is ideally used in high rpm, sporty performance cars like Lexus performance sedans or coupes.

Swaps / Custom Builds: If an engine swap is done, it will entail balancing packaging constraints, cooling, exhaust, ECU integration, wiring harness, mounts, and support components. The smaller, lighter V35A‑FTS may be simpler to package in certain chassis, but configurations involving turbos make things more complex.

6. Daily Driving & Performance Response

This is how all engines behave to driving:

  • V35A‑FTS will be harder to drive day to day due to boost allowing you to be available at lower rpms. There will be firm mid-range pull, which is convenient with trucks, SUVs, and more heavy-duty trucks.
  • 2UR‑GSE gets its power at higher rpms. You’ll achieve linear power ramp, unadulterated engine note, and non-stop performance if driven aggressively. 35A-FTS vs 2UR-GSE
  • Turbo lag (if bad engineering) will stun reaction in the V35A‑FTS unless properly tuned; optimally matched ECU and turbo package must be utilized.
  • Comfort, noise, vibration: The V8 can have more even natural balance at certain rpms, but current engineering in V35A‑FTS renders NVH under control. 35A-FTS vs 2UR-GSE

7. Summary & Recommendation

If we were to summarize:

  • V35A‑FTS: A newer, high-output twin-turbo V6 with V8 torque in a lower weight package, tuned for every day usable output, but needing meticulous maintenance.
  • 2UR‑GSE: A proven naturally aspirated V8 engineered for high-revving performance with a nostalgic premium and comparative mechanical simplicity. 35A-FTS vs 2UR-GSE

Which one is “better” depends on your needs. Need modern turbos’ performance, gas mileage, and torque? Use V35A‑FTS. Need classic V8 roar, more straightforward maintenance, and high-rev thrill? Use 2UR‑GSE.
