Choosing the right performance package for a Toyota GR Supra A90 or A91 starts with three questions: how much power do you want, do you plan to retain the stock turbo, and what fuel and drivetrain upgrades are appropriate for the build? East Coast Supra’s Stage 1 through Stage 4 packages provide a progression from a responsive stock-turbo setup to a complete big-turbo, supplemental-fueling and drivetrain-supported combination.

Quick answer: Stage 1 is the pump-gas stock-turbo entry point. Stage 2 adds flex-fuel capability. Stage 3 moves to an upgraded Pure 800 turbo. Stage 4 is the complete 800+ HP big-turbo package with port injection and drivetrain support.

A90/A91 Supra Power Package Comparison

Stage 1 | 480 HP label | Stock turbo | Pump gas | Best for a responsive, straightforward performance foundation.
Stage 2 | 550 HP label | Stock turbo | Flex fuel | Best for drivers who want greater fuel flexibility and optional methanol injection.
Stage 3 | 650 HP label | Pure 800 upgraded turbo | Flex fuel | Best for a serious upgraded-turbo street or race build.
Stage 4 | 800+ HP label | Boost Logic big-turbo system | Port injection and flex fuel | Best for high-output competition-focused builds with drivetrain support.

The horsepower figures above are the package labels and intended performance tiers. Actual output varies with model year, ECU access, fuel quality, calibration, supporting hardware, transmission configuration, dyno type and environmental conditions.

Stage 1: The Stock-Turbo Pump-Gas Foundation

Stage 1 is the entry point for drivers who want a coordinated package while retaining the factory turbo and running pump gas. It combines an EcuTek programmer and license, a custom stock-turbo pump-gas calibration, CTS Turbo 4-inch intake, Forge boost pipes and an East Coast Supra downpipe.

Choose Stage 1 when the goal is improved response and performance without immediately adding flex-fuel hardware or an upgraded turbo. View the Stage 1 Power Package.

Stage 2: Stock Turbo with Flex Fuel

Stage 2 retains the stock turbo but adds the fuel-system flexibility that many A90/A91 owners want before moving to a larger turbo. The package includes EcuTek hardware and licensing, a custom flex-fuel stock-turbo calibration, CTS intake, Forge boost pipes, East Coast Supra downpipe and a Visconti flex-fuel kit.

An AEM V2 or Titan Motorsports methanol-injection kit can be selected as the Stage 2+ option. Choose Stage 2 when you want a stock-turbo build centered on flex-fuel capability and a clear path toward additional cooling and performance support. View the Stage 2 Power Package.

Stage 3: Pure 800 Upgraded-Turbo Package

Stage 3 is the transition from stock-turbo performance into an upgraded-turbo system. Its core components include EcuTek tuning, CTS intake, Forge boost pipes, East Coast Supra downpipe, Visconti flex-fuel hardware, a choice of AEM or Titan methanol injection, and a Pure Turbo 800.

The Stage 3+ configuration adds port injection and ID1050 injectors for additional fueling capacity. Choose Stage 3 when an upgraded turbo is part of the plan but the build does not yet require the complete big-turbo and drivetrain package included with Stage 4. View the Stage 3 Power Package.

Stage 4: Complete 800+ HP Big-Turbo Build

Stage 4 is the most comprehensive East Coast Supra power package. It is built around a Boost Logic turbo system with a Garrett G30-900, with a G35-1050 available by request. The package also includes the matching Boost Logic intake, charge pipes and downpipe, custom EcuTek flex-fuel calibration, Visconti flex-fuel hardware, Titan methanol injection, an East Coast Supra port-injection setup with an AIC controller and ID1050 injectors, and upgraded DSS axles.

A Pure Drivetrain Solutions Stage 1 transmission upgrade is recommended at this level and can be configured through the product options. Choose Stage 4 when the vehicle is being planned as a complete high-output system rather than as a collection of individual parts. View the Stage 4 Power Package.

Which Supra Power Package Should You Choose?

Choose Stage 1 for a pump-gas, stock-turbo package with the core airflow and tuning hardware matched together.
Choose Stage 2 when you want to retain the stock turbo while adding flex-fuel capability and an optional methanol system.
Choose Stage 3 when the build calls for a Pure 800 upgraded turbo and a more substantial fueling strategy.
Choose Stage 4 when the plan is an 800+ HP big-turbo build with port injection, upgraded axles and transmission planning.

What Must Be Confirmed Before Ordering?

Model year and ECU production date
Current ECU unlock or clone status
Pump gas, ethanol blend and intended fuel strategy
Existing turbo, fueling, cooling and drivetrain hardware
Transmission condition and intended vehicle use

An unlocked ECU is required for tuning. ECUs dated June 2020 or later require a clone. Installation is not included in the listed package prices, and certain components are intended for sanctioned competition use. Confirm current requirements and vehicle compatibility before ordering.

Frequently Asked Questions

Can I use a Stage 2 package with the stock turbo?

Yes. Stage 2 is specifically structured around the stock turbo while adding flex-fuel capability and offering an optional methanol-injection system.

When do I need port injection?

Port injection is offered as the Stage 3+ fueling upgrade and is included in the Stage 4 package. The correct fueling configuration depends on the turbo, fuel blend, calibration and intended output.

Does an A90/A91 Supra ECU need to be unlocked?

Yes. The ECU must be unlocked before tuning. ECUs dated June 2020 or later require a clone. Confirm the ECU date and current status before purchasing tuning hardware or a power package.

Is installation included?

No. Installation is not included in the listed package prices. East Coast Supra can help confirm the correct package and discuss installation or freight options where applicable.
