The Toyota GR Supra (A90 generation, also called MK5 Supra) is a sports car produced from 2020 to 2026 model years, marking the revival of the iconic Toyota Supra nameplate that was last sold in the US through the 1998 MK4 generation. The A90 GR Supra is the result of a joint development partnership between Toyota and BMW, with both companies sharing development costs to create a sports car platform that would otherwise have been too expensive for either company alone. The result was the Toyota GR Supra and the BMW Z4 G29 roadster, sharing platform, engines, and major mechanical components, with both vehicles built at the Magna Steyr plant in Graz, Austria.
Important disclosure: The GR Supra uses BMW engines. The 3.0L turbo inline-6 is the BMW B58 (382 hp in updated 2021+ US trim, 335 hp in pre-update 2020 US trim), and the 2.0L turbo inline-4 (introduced for US market in 2021) is the BMW B48 (255 hp). The turbochargers are essentially BMW components, made by Mitsubishi for BMW (Mitsubishi MGT on B58 inline-6, TF035-family on B48 inline-4). The B58 uses a twin-scroll turbocharger for better low-end torque, while the B48 uses a single-scroll turbo appropriate for the smaller engine. Both turbos feature water-cooled bearing cartridges in addition to oil lubrication for improved durability. Wastegate control is electronic on most variants (replacing earlier pneumatic actuators).
The most common reasons GR Supra owners replace the turbocharger are: bearing wear from oil contamination, insufficient cool-down after spirited driving, or extended high-load operation (the most common failure mode), wastegate actuator failure causing under-boost or over-boost conditions (electronic actuator failure on later cars or pneumatic actuator failure on early cars), oil seal failure causing smoke from exhaust under boost or excessive oil consumption, compressor wheel or turbine wheel damage from foreign object ingestion (rare but possible), integrated exhaust manifold cracking from thermal stress (rare), or after aggressive aftermarket tuning that exceeded the factory turbo limits.
GR Supra performance tuning has revealed that the factory turbo has significantly more headroom than Toyota's conservative factory tuning suggests, with the B58 turbo capable of supporting 500+ hp on aftermarket tunes before reaching its limits. However, this also means that some GR Supras with aftermarket tunes have prematurely worn turbo bearings or other components. Our new OEM-specification turbocharger at $1,495 saves significant money over $2,500 to $3,800 dealer pricing. The BMW Z4 G29 turbocharger is mechanically identical to the GR Supra turbocharger for the same engine variant, expanding cross-reference options.
| Detail | Description |
|---|---|
| 3.0L B58 Inline-6 Turbocharger | Single twin-scroll turbocharger from Mitsubishi MGT family. Twin-scroll design uses two separate exhaust pulse paths for cylinder pairs to improve low-end torque response. Larger overall size matching the 3.0L six-cylinder application. 382 hp factory rating (2021+ updated US tune) or 335 hp (pre-update 2020 US tune). The flagship engine variant. |
| 2.0L B48 Inline-4 Turbocharger | Single-scroll turbocharger from Mitsubishi TF035 family. Smaller size matching the 2.0L four-cylinder application. 255 hp factory rating. Introduced for US market in 2021, base engine variant offering more affordable Supra ownership. |
| Cross-Vehicle Compatibility | These turbos are also used on BMW Z4 G29 (same engines, same turbos). Many BMW B58 and B48 engines across other BMW vehicles use similar but not always identical turbo variants, always verify specific part number before assuming compatibility. |
| Detail | Description |
|---|---|
| INCLUDED | The complete turbocharger assembly with compressor housing, turbine housing, integrated exhaust manifold (where applicable), bearing cartridge with water and oil ports, wastegate actuator (electronic on later variants), and mounting flanges. Pre-balanced compressor wheel. |
| NOT INCLUDED | Coolant lines (replace if cracked, source separately), oil supply line and oil return line (replace gaskets/seals at minimum), exhaust gaskets (always replace, source separately), heat shields (transfer from old turbo), oxygen sensor (transfer from old turbo, replace if old), wastegate actuator if separate, ECM software updates or programming. |
| Tools You Need | Metric socket set, torque wrench, oxygen sensor socket, hose clamp pliers, exhaust paste, fresh engine oil (turbo replacement requires oil change), coolant for refilling cooling system, basic hand tools, jack and stands or lift, helper recommended for handling the heavy turbo assembly. The replacement is a 6 to 10 hour DIY project for an experienced sports car mechanic, or 4 to 6 hours of professional shop labor. |
The Toyota GR Supra turbocharger is compatible with the following A90 variants. Confirm year and engine before ordering.

The GR Supra A90 turbocharger is essentially a BMW B58 or B48 turbocharger since the engines are BMW. Cross-reference with BMW Z4 G29 of same engine variant is direct. Cross-reference with other BMW vehicles using B58 (340i, M340i, Z4 sDrive40i, X3 M40i, etc.) and B48 (330i, Z4 sDrive30i, X3 sDrive30i, etc.) may work with verified part numbers but configurations vary. NOT compatible with previous MK4 Toyota Supra (1993 to 2002, used Toyota 2JZ-GTE twin-turbos, completely different vehicle). Always confirm by Toyota OR BMW part number for proper application.
Not sure if this Toyota GR Supra turbocharger fits your car? Call (240) 301-0095 with your year (2020 to 2026), engine (3.0L B58 inline-6 or 2.0L B48 inline-4), and trim level. For 2020 models specifically, confirm whether your B58 was updated to the 382 hp tune (typically requires ECU update). Our team confirms the right turbocharger for your specific GR Supra application before we ship. BMW Z4 G29 owners with the same engines can also call for cross-reference part identification.
These new OEM-specification Toyota GR Supra turbochargers are inspected before shipping. Quality control includes:
Each turbocharger ships with the engine variant clearly identified (B58 3.0L or B48 2.0L). Critical install notes: always prime the new turbocharger with clean oil before first startup, use OEM-specification synthetic oil (BMW-approved), bleed the cooling system properly to prevent air pockets at the turbo, and allow proper warmup before high-load driving. After hard driving, allow 30 to 60 seconds of idle cool-down before shutoff to prevent oil coking on the bearing cartridge.
