This article aims to provide a comprehensive, SEO-optimized guide to answer that very question, while also offering deeper insight into the performance, engine options, and tuning potential of the Honda Altezza series.
From its iconic status in Japanese auto culture to its global appeal, the Altezza—known as the Acura CSX or Infiniti G20 in some markets—has an enduring legacy. But did it ever come with a turbocharged engine from the factory? We’ll explore that, along with popular modifications and misconceptions that often surround this compact luxury sedan and coupé.
The Origin and Popularity of the Honda Altezza
Before diving into the technical specs, let’s take a brief look at the history of the Honda Altezza and why it captured the hearts of automotive fans, especially in the street racing and tuning scenes.
The Honda Altezza was introduced in Japan during the late 1990s as a luxury compact vehicle, produced by Honda under its Acura brand for export markets. The name “Altezza” is Italian for “height,” symbolizing both prestige and the car’s standing in Honda’s lineup.
It was available in both sedan (LX-R) and coupé (LSX) versions and was often praised for its sharp styling, plush interior, and sporty handling. While early Altezzas were positioned against cars like the Toyota Altezza (which shares no relation, despite the similar name), it was the engine choices and the platform’s lightweight design that sparked interest among tuners worldwide.
Altezza Generations Overview
Let’s summarize the basic versions of the Altezza:
- 1st Gen (1998–2000): Equipped with naturally aspirated inline-four engines like the D17A and D16Y8.
- 2nd Gen (2001–2006): Featured the improved D17A2 engine and more refined luxury features.
While some models—like the Infiniti G20 or Acura CSX—used different engine codes and options, the Altezza itself, particularly the Japanese domestic market (JDM) versions, never came with a turbocharger at the factory level.
Does Altezza Have Turbo? The Fact Check
To answer the question at hand directly: No, the Honda Altezza does not have a turbocharged engine from the factory. The car was designed as a lightweight, front-wheel-drive compact sedan or coupé with naturally aspirated engine configurations only.
This section dives into engine specifications that support this claim and explores whether the car is compatible with turbo conversions—a hot topic among performance tuners.
Engine Specifications of the Altezza
The Altezza is powered primarily by the lightweight Honda D-series engines, known for reliability, fuel efficiency, and great balance for tuning purposes. These engines were:
- D16Y8: A 1.6L engine producing around 125 PS (92 kW), used in early 1998–1999 Altezza LX-R models.
- D17A2: A more common 1.7L engine producing approximately 125–130 PS (93–97 kW), known for smoother performance, used in 2000–2006 models.
Though these engines are known for high-revving characteristics and modification potential, none came with forced induction technology from the factory. That is to say, the factory-manufactured Honda Altezza offers a naturally aspirated setup in all engine options across all production years.
Common Misconception: Confusing Altezza with Other Tuning Cars
Some enthusiasts get confused between Altezza models and Japanese tuning icons like the Toyota Altezza RX-Z, which is actually a different car produced by Toyota (internally as the Lexus IS200/IS250 in later years, but originally known as the Altezza RX-Z in Japan). That particular model never had a factory turbo either, though people often associate it with powerful tuning culture thanks to its 2JZ and 1JZ engines.
This confusion often leads to the mistaken belief that Honda’s Altezza also came turbo-equipped. The truth is that both vehicles—Honda’s Altezza and Toyota’s Altezza—were naturally aspirated when new and gained popularity largely due to modifications by enthusiasts.
Turbo Modifications for the Honda Altezza
Although the Altezza didn’t come with a factory turbocharger, it’s very commonly considered a prime candidate for turbocharged modifications. In this section, we’ll explore the feasibility, required parts, and benefits of turbocharging the Honda Altezza engine.
Is Altezza Engine Compatible with Turbo Setup?
Yes, the Honda D17A or D16 series engines used in the Altezza are compatible with turbocharging, but doing so requires a significant amount of engineering, mechanical know-how, and investment. Let’s break it down.
Basics of Turbocharging a Naturally Aspirated Engine
To turbocharge a standard engine like the D17A, you’d need the following setup:
- Turbocharger unit
- Manifold and downpipe
- Intercooler
- Boost controller
- Oil feed and drain lines
- ECU tuning (standalone or piggyback)
Additionally, you’d probably need forged pistons and rods, especially if you’re planning to run significant boost for long-term reliability.
Performance Upgrades: From Stock to Turbocharged
Here’s a performance comparison table that shows what you can expect before and after a turbo modification on a D17A engine:
| Parameter | Stock (D17A2) | Post-Turbo Upgrade (Estimate) |
|---|---|---|
| Engine Displacement | 1.7L | 1.7L (can be increased with stroker kits) |
| Horsepower | 130 HP | 180–220 HP (with moderate boost) |
| Torque | 108 lb-ft | 160–200 lb-ft (with intercooler & tuning improvement) |
| 0-60 mph (approx.) | 9.5–10 seconds | 6.5–7 seconds (depending on boost levels) |
| Drivetrain | FWD | FWD or AWD (with additional conversion) |
This level of transformation requires not just engine work but also transmission reinforcement and tuning. As a result, it makes sense mainly for dedicated tuners looking to push the boundaries of what the affordable Altezza platform can do.
Turbocharged Builds in the Tuning Scene
In Japan and global tuning communities, there have been notable builds where D-series engines—specifically from the Civic, CR-V, and yes, Altezza—have been turbocharged in cars like the Civic, Del Sol, and CRX. As such, the Altezza has become somewhat of a DIY project for those looking for a unique platform to modify.
Because the Altezza is relatively lighter than other D-series-equipped vehicles and offers a better seating position for spirited driving, it’s become a popular sleeper car option after engine upgrades.
Modifications frequently include:
- D-series block upgrades (main and rod bearings)
- Upgraded turbo manifolds and intercooler piping
- Standalone engine management for proper fuel and timing control
Many tuners pair the turbo build with suspension work including coilovers and limited-slip differentials to manage increased grip and handling.
Identifying Altezza Variants and Import Models
This section is especially relevant for those purchasing used imports or looking into JDM and overseas variations of the Altezza. It’s easy to mix up different generations and trim levels.
Key Altezza Trim Variants
There are several trim and body variations of the Altezza:
- Altezza LX-R (Sedan): The entry-level 4-door luxury sedan with D16Y8 or D17A series engines.
- Altezza LSX (2-door Coupe): Often more sporty, featuring a tighter turn radius and a sleeker design, also powered by the D17A series.
- Acura CSX (North America Export): North American counterpart, slightly higher trim but still naturally aspirated.
- Infiniti G20: Sometimes mistaken for the Altezza but is a Nissan-produced vehicle, with different engine lineups—some of which were turbocharged in later model years.
It’s crucial to verify which model you’re considering before jumping to conclusions about its engine capabilities.
Turbo Variants of Other “Altezza” Named Cars
Confusion also arises from other brands. For example, as previously mentioned, Toyota also named its version the “Altezza RX-Z,” which is a different car entirely. These models were never turbocharged by the factory either, though heavily built versions of them like JZX100/110 have since become turbocharged tuning icons.
Does Altezza Have Turbo in Rallispec or JDM Circles?
JDM performance culture is synonymous with Honda’s D-series engines. The Altezza never made it into rally circles as a competitive platform, due to its front-wheel-drive layout and lack of four-wheel control systems in most models.
However, among Japanese domestic mechanics and tuners, there have been numerous isolated cases of enthusiasts turbocharging their Altezzas for track-inspired performance or to participate in underground racing events. This practice isn’t mainstream, but it’s more common among niche subcultures.
Common Turbo Install Kits for D-Series Engines
Among tuners and JDM performance specialists, several companies sell turbo kits for the D-series engines, many of which could be fitted to the Altezza variant:
- Toda Racing: Known for high-quality kits and tuning products.
- Hasport: Offers comprehensive turbo systems and accessories.
- Honda D Turbo Club: Grassroots performance communities online often share DIY how-to guides.
Most experienced tuners suggest starting with D16Z6 or D16Y8 engines for turbo modification rather than D17 due to their higher redline and compatibility with earlier turbo systems. Still, skilled engineers can adapt turbo systems to D17 engines found in later Altezzas.
Aftermarket Support for Turbo Upgrades
Because the D-series engines are so widely used, parts availability, tuning options, and community support are relatively robust. For those considering a turbo conversion:
- Research existing build logs
- Determine a realistic budget (expect $2k–$5k for proper setup)
- Use tuning shops experienced with Honda engines
It’s an ambitious but attainable project for enthusiasts who enjoy the art of car customization.
OEM Tuning Options vs. Third-Party Upgrades
Some might wonder, did Honda ever officially offer a turbo package for the Altezza? The short answer is no.
Instead, we can contrast the Altezza with vehicles that did have OEM turbo options.
Comparison with Other Honda Turbo Models
| Model | Platform | Factory Turbo Available? | Engine |
|——-|———-|————————–|——–|
| Honda CRX Si (non-turbo) | Front-wheel drive | No | D16Z6 |
| Honda Integra Type R | Front-wheel drive | No | B18C |
| Honda Prelude VTEC | Front-wheel drive | No | H22A / F22A |
| Honda Accord Euro R | Front-wheel drive | Yes (Euro R 2007–) | K20A |
| Honda Altezza | Front-wheel drive | No | D16, D17 |
This comparison shows that while Honda did explore turbocharging across several of its model lines, the Altezza series never benefitted from factory forced induction.
Why Didn’t Altezza Feature a Factory Turbo? Historical Insight
When Honda designed the Altezza, their focus was on entering the compact luxury sedan market, emphasizing fuel economy, comfort, and balanced driving dynamics. The idea was to compete with Toyota and Nissan’s similarly-styled vehicles using Honda’s reliable inline-four engines.
Honda did not anticipate that the Altezza would become such a favorite in tuning circles—its natural air intake, small size, and affordability made it more of a commuter vehicle than a track-ready machine at its initial launch.
In contrast, turbocharged Honda models like the Integra, Accord, and certain Civic Type R editions were designed with performance in mind from the factory and targeted different niches.
Who Should Consider Turbocharging a Honda Altezza?
While the stock Altezza is a reliable and efficient commuter car, there are specific profiles of drivers who might find the idea of turbocharging appealing:
- First-time tuners: The D-series engine is well-documented, so this could be a learning project.
- Car enthusiasts building a sleeper: With its factory styling and low visibility in tuning media, the Altezza makes a great stealth performance car.
- DIY mechanics: Enthusiasts looking for cost-effective forced-induction builds can find a solid foundation in the Altezza.
For those considering this kind of build, it’s important to consult experienced tuners, budget carefully, and invest in proper fuel and engine management systems.
Important Considerations Before Going Turbo
Before diving into a turbo conversion:
1. Budgeting at least $2000+.
2. Choosing between budget-friendly turbo kits or more robust setups (e.g. T3-T4 turbos with intercooler).
3. Upgrading the engine internals (forged rods/pistons if desired boost is over 15 psi).
Again, many tuners prefer earlier D16-based engines for easier turbo conversions, but D17A engines are gaining popularity thanks to slightly more torque.
Conclusion: Does Altezza Have Turbo?
To summarize: No, the factory Honda Altezza does not come with turbocharged engines—but with its lightweight body, FWD efficiency, and strong aftermarket support, it makes for a compelling project car ripe for turbo modifications by tuners worldwide.
Whether you’re buying a stock Altezza for comfort and efficiency or planning a full-on turbo build depends entirely on your style, passion, and technical appetite.
If you’re considering acquiring one—especially from JDM or as a restoration project—know that the car offers a rewarding canvas for those willing to modify and improve it.

What is the Honda Altezza, and what engines are commonly associated with the model?
The Honda Altezza is a sporty compact sedan introduced in the late 1990s, primarily marketed in the Japanese domestic market (JDM). It was known for its sharp styling, front-wheel-drive layout, and availability in various trim levels, including models powered by Honda’s high-revving VTEC engines. The Altezza line was a collaboration between Honda and Toyota, with the car being a rebadged version of the Toyota Altezza (also known as the Lexus IS200 in some markets).
In its standard form, the Honda Altezza did not come equipped with a turbocharged engine. The most notable engine option was the 1.8L inline-four B18C, known for its high-revving performance and VTEC technology. This engine emphasized naturally aspirated performance rather than forced induction, offering impressive responsiveness and a smooth power delivery, especially in higher trim levels like the B18C Type R variant.
Did any Honda Altezza models ever come with a turbocharged engine from the factory?
No, none of the Honda Altezza models were ever factory-fitted with a turbocharged engine. The Altezza was offered with naturally aspirated powerplants only, focusing on high-revving capabilities and driving dynamics rather than forced induction. Honda’s performance strategy at the time leaned heavily on VTEC technology to maximize horsepower without the use of turbochargers.
While the base engine was the B16A series with VTEC, the top-tier variant, the B18C Type R, became very popular for its high horsepower output and track-ready characteristics. Despite not being turbocharged, the B18C was known for its reliability and performance potential. Therefore, any turbo-equipped Altezza on the road today would be the result of aftermarket modifications rather than a factory setup.

The Honda Altezza wasn’t positioned as a turbocharged performance car due to its engineering philosophy and market targeting. Honda focused on high-revving, lightweight, and efficient engines that could deliver strong performance without relying on forced induction. The use of VTEC technology allowed Honda to optimize valve timing and lift for better performance in the upper RPM range, making turbocharging unnecessary for the Altezza’s intended use and audience.
The driving experience offered by the B18C engine is linear and engaging, with smooth power delivery that appealed to driving enthusiasts. Unlike turbo engines, which can produce sudden power spikes, the Honda Altezza emphasized control and predictability. This design made it more suitable for street performance and track driving without the complexities of turbocharging systems.
Can the Honda Altezza be modified to include a turbocharger?
Yes, the Honda Altezza, particularly models equipped with the B-series engines like the B18C, can be modified to include a turbocharger. While the engine wasn’t designed for forced induction from the factory, the robust nature of Honda’s B-series engines makes them ideal candidates for turbocharged conversions. Enthusiasts frequently consider adding a turbo to extract significantly more horsepower and torque, especially for drag racing or time attack builds.
Such modifications typically involve upgrading engine internals (pistons, rods, crankshaft), installing a turbo kit, and tuning the ECU to manage boost levels and fuel delivery. It also requires upgrading intercoolers, exhaust systems, and fuel systems to support the increased power output. However, it’s crucial to balance the budget and practical goals since turbo conversions can be complex and costly.
What advantages does the naturally aspirated B18C engine offer compared to a turbocharged alternative?
The naturally aspirated B18C engine in the Honda Altezza is known for its reliability, responsiveness, and smooth power delivery. Without the added complexity of a turbocharger system, such engines generally offer lower maintenance costs and a more predictable driving experience. The high-revving nature of the B18C allows for an engaging drive, especially in cars with manual transmissions, making it a favorite among purists and circuit drivers.
Compared to turbocharged engines that generate power through forced induction, the B18C’s powerband is linear and easier to modulate. This makes the car more enjoyable in scenarios where throttle precision and engine feedback are essential, such as in canyon driving or track events. Additionally, since the engine lacks turbo lag, power delivery is immediate, enhancing its driving dynamics.
How does the power output of the Honda Altezza compare to other cars in its class with turbocharged engines?
The Honda Altezza’s B18C engine produces around 190 horsepower in its factory-tuned form, which was quite competitive for a naturally aspirated inline-four in its era. While this figure is not as high as some turbocharged rivals like the Mitsubishi Lancer Evolution or Subaru WRX models, which can generate 270+ horsepower in stock form, the Altezza’s power-to-weight ratio and responsive handling help close the gap in real-world driving.
Turbocharged cars typically offer more torque and faster acceleration off the line, especially in lower RPM ranges, whereas the Altezza relies on high-revving performance and a lightweight chassis. While it may not dominate in straight-line speed like turbocharged vehicles, the Altezza excels in offering a balanced, engaging driving experience that differs from the aggressive nature of forced induction competition.
Is the Honda Altezza a good candidate for car enthusiasts looking to build a turbocharged street or race car?
Yes, the Honda Altezza remains an excellent platform for car enthusiasts aiming to build a high-performance turbocharged street or race car. Thanks to its strong chassis, balanced handling, and durable B18C engine, adding a turbocharger can unlock significant horsepower gains while maintaining the lightweight and nimble characteristics of the original design. The car can be optimized for various purposes from daily-driven turbo compacts to full race machines.
Many builders and tuners favor the B18C for its excellent aftermarket support, making it relatively straightforward to source turbo kits and performance parts. When built properly with supporting modifications including forged internals and upgraded transmissions, the Honda Altezza can reliably handle boost levels that push it beyond 400 horsepower. This versatility makes it a rewarding project for those looking to create a unique and powerful performance car.
