BRZ Manifold Kit + 62mm Throttle Body + Tune — 2022+ WRX VB

• BRZ manifold adapter kit: manifold-to-head adapters, throttle-body adapter, MAP extension harness, EGR adapter, port-injection plugs, and MAP plug
• 62mm high-flow throttle body
• Custom WRX Atlas e-tune for the 2022+ VB WRX
• Post-purchase calibration guidance and data-driven revisions

The manifold itself is not included — you supply it. Three versions work with this kit:

• Gen 1 plastic: the most budget-friendly option.
• Gen 1 aluminum: the best-looking, “sexiest” option.
• Gen 2 plastic: recommended for the best performance.

For context only, a third-party FA20DIT BRZ-manifold test reported approximately +26 hp / +18 lb-ft on 93 octane and +36 hp / +21 lb-ft on E85. Those figures are not a GropeTuned dyno result, do not represent a guarantee, and may not apply to the FA24F or your vehicle. Throttle-body and calibration results vary with the complete setup, fuel, and vehicle condition.

• A compatible BRZ manifold is required and is not included.
• A throttle-body wiring extension is required. You will need one Ballenger Motorsports Ford/Mazda 6 Way DBW Throttle Body Connector Extension (CONN-86195). Purchase separately; not included.
• A complete front-mount intercooler setup is required and is not included.
• The intercooler pipe run must be custom. It can typically be made with two correctly sized universal intercooler-pipe J-bends. No intercooler piping is included.
• Source injector gaskets for the port-injection plugs, WRX and BRZ throttle-body gaskets, WRX and BRZ manifold-to-head gaskets, and WRX and BRZ MAP-sensor gaskets.
• Adapt the factory PCV hose to the manifold.
• Carefully bend the HPFP outlet away from the manifold, or cut the manifold for proper clearance.
• Trim the plastic beneath the manifold to clear the EGR adapter.
• Trim the in-head dividers as needed for clearance and airflow; use the supplied reference photo as a guide.
• The BRZ MAP mounting hole can be drilled to accept the WRX MAP sensor using a 31/64-inch drill bit.
• Disassemble the OEM TGV assemblies from the WRX manifold. Remove the rod from the remaining TGV motor/gear housing—the piece shown at the bottom right of the supplied TGV photo—before leaving it in the engine bay.
• Leave the TGV assemblies electrically connected in the engine bay and use the included calibration to disable them and prevent codes or drivability issues.
• The tune requires a suitable Atlas adapter and laptop. Follow the logging instructions after purchase.

Advanced installation: verify fitment, clearances, sealing surfaces, and fastener torque before starting the car. Installation and tuning should be performed by someone experienced with Subaru FA24F systems. Check local emissions and road-use requirements.

Because the kit components are hand-made, the hardware portion includes a 3-year limited replacement-parts warranty against manufacturing defects. Warranty coverage does not include installation damage, incorrect modifications, or normal wear.

Everything in this bundle is also sold separately — the bundle costs less, and the included tune is developed through the remote tuning process after installation.

• BRZ Intake Manifold Adapter Kit — $350
• 62mm High-Flow Throttle Body — $299
• WRX Atlas E-Tune — $450 (included here)

• Flex Fuel Tune Add-On — $100
• Speed Density Tune Add-On — $100
• Want Teach-As-We-Go alongside your included tune? Contact GropeTuned before purchasing to confirm the teaching upgrade cost and avoid paying twice for the calibration.

When the manifold side is sorted, the turbo is what's left. Both the G25-660 and G30-660 kits include their custom tune in the price too, and the hot side can be heat-shielded while it's off the car.
