A turbocharger upgrade is one of the most significant modifications you can make to a modern performance vehicle.

Unlike many bolt-on upgrades, changing the turbocharger directly changes the airflow capacity of the engine and can fundamentally alter the power potential of the entire build.

That is why choosing the right turbo matters.

PureTurbos has developed a broad range of upgraded turbochargers for performance platforms from BMW, Porsche, Audi, Mercedes-Benz, Toyota, Nissan, and other manufacturers. The lineup includes staged and high-flow turbo upgrades designed around specific engines and applications rather than a one-size-fits-all approach.

At XPH, the PureTurbos catalog ranges from relatively conservative upgrades to large turbo solutions intended for substantially higher-output builds.

The Turbo Should Match the Build

A bigger turbo is not automatically a better turbo.

The ideal upgrade depends on what the vehicle is being built to do.

A daily-driven street car may benefit from an upgrade that improves power potential while retaining responsive spool characteristics.

A drag-oriented or high-power build may justify a substantially larger turbo capable of moving considerably more air at higher engine speeds.

Between those extremes are countless combinations.

That is why PureTurbos uses different upgrade levels and turbo sizes across its product range, including models such as Pure500, Pure600, Pure650, Pure750, Pure800, Pure900, Pure1000, and Pure1200.

The correct choice should be based on the engine, intended power level, fuel system, tuning strategy, and supporting modifications.

BMW Remains a Major Part of the Lineup

PureTurbos has extensive coverage for BMW's turbocharged engines.

Its current BMW catalog includes:

• N20
• N26
• N54
• N55
• B46
• B48
• B58 Gen 1
• B58 Gen 2
• S55
• S58
• N63
• N63R
• S63
• S63TU
• S63 F9X
• N74

These applications cover everything from four-cylinder BMWs to high-output M cars and V8-powered models.

This breadth is one of the reasons PureTurbos is particularly relevant to BMW enthusiasts building beyond the capabilities of their factory turbochargers.

N54: An Established Platform With Plenty of Headroom

The BMW N54 remains one of the most heavily modified BMW turbo engines.

PureTurbos offers several upgrade paths for it, including Pure Stage 1, Pure Stage 2, and Pure600 turbo upgrades.

The N54 Pure Stage 2, for example, is positioned as a substantially larger upgrade than the factory turbo configuration, while the Pure600 provides another option for owners pursuing greater airflow capacity.

For an N54 build, the decision between different turbo options should take into account the desired powerband, fuel system, tuning strategy, and intended use of the vehicle.

N55 Options From Street Builds to Higher Power

The N55 has also received multiple PureTurbos upgrade options.

The current XPH catalog includes:

• N55 Pure500
• N55 Pure600
• N55 Pure750
• N55 Stage 2
• N55 inlet components

This allows an N55 owner to select a turbo according to the overall direction of the build rather than being restricted to one upgrade level.

The Pure600 N55 upgrade, for example, uses a billet compressor wheel, a larger and stronger turbine wheel, and an upgraded bearing housing while retaining OEM-style housing architecture.

That type of design is particularly useful for enthusiasts who want increased turbocharger capability without turning the installation into a completely custom fabrication project.

B58: Multiple Generations, Multiple Turbo Choices

The B58 illustrates why exact engine identification matters when selecting an upgraded turbo.

PureTurbos offers separate products for B58 Gen 1 and B58 Gen 2 applications.

The current lineup includes Gen 1 Pure600, Pure800, and Pure900 options, while the Gen 2 catalog includes Pure600, Pure650, Pure800, and Pure900 upgrades.

That distinction is important.

A B58 is not simply a B58 when it comes to turbo fitment.

Chassis, engine generation, factory turbo configuration, and the intended application all need to be considered before selecting an upgrade.

Toyota Supra and the B58 Connection

The Toyota GR Supra A90/A91 is another major PureTurbos application.

Because the Supra uses BMW's B58 powertrain architecture, turbo upgrades for the platform have become an important part of the aftermarket.

PureTurbos currently offers Pure650, Pure800, and Pure900 options for the A90/A91 Supra, providing multiple stages for different power goals.

For Supra owners, this creates a progression from moderate turbo upgrades to considerably more aggressive setups without requiring every build to use the largest available turbo.

S55: Built for BMW M Applications

The S55 powers the F80 M3, F82 M4, F83 M4 Convertible, and F87 M2 Competition, making it another platform with substantial turbo-upgrade potential.

PureTurbos offers several S55 configurations, including Pure Stage 2, Pure Stage 2+ and Pure800/Pure1000 solutions.

The current catalog therefore covers both moderate and high-output S55 builds.

This is important for an M car because the desired result can vary dramatically.

One owner may want stronger midrange performance for street driving.

Another may be building specifically around high-RPM power and maximum airflow.

The turbo should be selected accordingly.

S58: The Next Generation of BMW M Performance

The S58 has brought even greater factory performance potential to BMW's modern M lineup.

PureTurbos currently offers an S58 Pure Stage 2+ upgrade for the platform.

The S58 application is particularly interesting because the engine already produces substantial power in factory form.

As a result, a turbo upgrade is generally considered as part of a broader build rather than as an isolated modification.

Fueling, calibration, cooling, exhaust flow, drivetrain capability, and the intended use of the car all become increasingly important as output rises.

BMW's V8 Platforms

PureTurbos also supports BMW's larger turbocharged V8 engines.

The current catalog includes upgrades for:

• N63
• N63TU
• N63R
• S63
• S63TU
• S63 F9X

Options include Pure Stage 1 and Stage 2 configurations as well as larger Pure800 and Pure900 applications.

For the F9X-generation M5 and M8, PureTurbos offers a Pure900 upgrade specifically for the S63TU engine.

The catalog also extends to the N74, with the Pure1200 upgrade designed for the 2017+ BMW M760i. XPH lists this application as an OEM-housing turbo designed to support more than 1000 whp.

Beyond BMW

PureTurbos is not exclusively a BMW turbocharger company.

Its current XPH catalog includes upgraded turbochargers for several other performance platforms.

Porsche

Applications include:

• 718 Cayman 2.5L
• 991.1
• 991.2
• 992 3.0L Carrera/S/GTS
• 992 Turbo S
• 997.1
• 997.2
• Cayenne/GTS/Panamera

Available upgrades range into the Pure800, Pure850, Pure1000, and other configurations depending on the platform.

Audi

PureTurbos offers upgrades for:

• S4
• S5
• SQ5
• RS4
• RS5
• RS6
• RS7
• RSQ8

Current products include Pure700, Pure750, and Pure900 configurations depending on the engine and vehicle.

Mercedes-Benz

The lineup includes turbo upgrades for several Mercedes-AMG applications, including:

• CLA45
• GLA45
• A45
• C63S
• AMG GT
• E63S
• AMG GT Black Series

Depending on the engine, available upgrades include Pure550, Pure650, Pure900, and Pure1000 options.

Nissan

PureTurbos also offers a Pure1000 turbo upgrade for the Nissan R35 GT-R.

This gives GT-R owners another option when the factory turbochargers become a limiting factor in a high-power build.

Why Turbo Sizing Matters

The purpose of selecting a turbo upgrade is not simply to chase the largest advertised horsepower number.

Turbocharger characteristics affect how the engine produces power.

A larger turbo can provide more airflow at high engine speeds, but the ideal setup depends on the entire combination.

Important considerations include:

• desired horsepower
• torque target
• engine displacement
• fuel system capacity
• fuel type
• boost target
• exhaust flow
• intake flow
• intercooling
• transmission capability
• intended driving conditions
• tuning strategy

A street-driven vehicle and a dedicated drag car can require very different turbocharger specifications even if they use the same engine.

The Supporting Hardware Matters

Installing a larger turbo is rarely the final step.

The rest of the vehicle needs to support the additional airflow and power.

Depending on the application, a turbo upgrade may require consideration of:

• ECU tuning
• fueling
• intake and inlet flow
• charge-air cooling
• exhaust flow
• wastegate control
• transmission capacity
• engine cooling
• drivetrain components

The exact requirements depend heavily on the vehicle and turbo selected.

For example, XPH's N55 Pure Stage 2 listing provides configuration options for a high-flow silicone inlet, upgraded diverter/blow-off-valve hardware, and turbo model, demonstrating how supporting components can become part of the turbo selection process.

OEM-Style Packaging

One of the advantages of application-specific turbo upgrades is maintaining predictable packaging.

The N55 Pure Stage 2, for example, uses OEM housings while incorporating upgraded internal components.

This type of approach can provide significantly greater turbocharger capability while maintaining the packaging characteristics of the original installation.

For enthusiasts, that can be preferable to converting an otherwise streetable vehicle into a completely custom turbo system.

From Moderate Upgrades to Extreme Builds

PureTurbos' staged approach makes it possible to select a turbo based on the direction of the build.

A smaller Pure upgrade can make sense when maintaining street responsiveness is a priority.

A larger Pure800 or Pure900 can make more sense when the build is targeting substantially greater airflow.

At the top end of the catalog, options such as the N74 Pure1200 demonstrate how far the product range extends for extreme applications.

The important point is that there is no universal "best" PureTurbos turbo.

There is only the turbo that best matches the engine and the goals of the build.

Selecting the Correct Application

Before ordering a PureTurbos upgrade, verify:

• exact vehicle
• chassis generation
• engine code
• engine generation
• turbo configuration
• wastegate configuration where applicable
• intended power target
• supporting modifications
• core requirements

This is especially important for engines such as the B58, where Gen 1 and Gen 2 applications use different turbo solutions.

Some PureTurbos products also involve refundable core deposits and specific core-return requirements, so those details should be reviewed on the individual product listing before ordering.

Built Around the Next Stage of the Build

PureTurbos occupies an important position between factory turbo hardware and fully custom turbo systems.

Its staged upgrades allow enthusiasts to move beyond the factory turbocharger while retaining application-specific packaging and a defined path toward additional power.

Whether the vehicle is an N55 BMW, B58 Supra, S55 M3/M4, S58 M car, Porsche 992, Audi RS model, Mercedes-AMG, or Nissan GT-R, the same principle applies:

Choose the turbo around the build, not the build around the turbo.
