SUPRA
Build for your B58.
Two-port or six-port. Automatic or manual.
500 / 800 / 1,000 / 1,200 wheel horsepower.
bootmod3, MHD, Pure, JDY and custom turbo options.
Build disclaimer: results are not guaranteed.
These guides and parts packages are suggested starting points. Horsepower figures are targets, not guaranteed results. No listed combination guarantees a particular power output, vehicle fitment or level of reliability.
Customers should do their own research and review the complete build with their own engine builder, installer and tuner before purchasing or installing parts. Confirm compatibility, all supporting modifications, fuel and tuning requirements, engine and drivetrain limits, and suitability for the intended use. Results vary with the vehicle, parts, fuel, installation, calibration and operating conditions.
Dedicated Toyota GR Supra 3.0 build guide. These are Supra selections, not the BMW B58 carts. The B48 2.0 Supra, MK4/2JZ, BMW Z4 and other BMW B58 models are outside this page. Two-port does not mean BMW Gen 1 fitment.
Start with the exhaust ports on your actual engine. Then choose the power target, transmission, steering side and tuning platform. The cart selects every listed catalog part by default; custom work and unresolved fitments stay visible in the build checklist.

Two ports and six ports need different turbo hardware
| System | Supra-specific specification |
|---|---|
| US model-year reference | US 2020 3.0 cars use the two-port arrangement; Toyota introduced a six-port head/exhaust arrangement and revised pistons for US 2021. This is a reference, not a global fitment rule. Toyota source. |
| Confirm the actual car | Give Kies the VIN, selling market, engine/head identity or flange photos, current turbo, transmission, steering side and existing modifications. Registration year, A90/A91 badge or the word “Gen 2” alone cannot determine a turbo order. Swapped engines and special editions need individual review. |
| Two-port turbo choices | Kies lists two-port Supra Pure650 and Pure850 core configurations. The JDY kit reviewed here has a six-port flange and is excluded from two-port carts. A custom two-port manifold is required for the APX route; a six-port conversion is a separate engine project. |
| Six-port turbo choices | Use six-port Supra variants and Supra inlet/charge-pipe geometry. JDY choices below explicitly select Supra and LHD/RHD. The available PURE900 cart variant is six-port; generic catalog references to two-port do not create a verified orderable two-port option. |
| DME / special cases | Check physical DME production date and software, including replacement ECUs. Quote the appropriate unlock only if required. New software, a prior unlock, a manual conversion or a Final Edition badge does not establish CustomROM/PI support automatically. |
Supra driveshafts and axles: automatic ≠ manual
| System | Supra-specific specification |
|---|---|
| 8HP51 automatic | At 800+ WHP the proposed cart includes Pure 8HP51 Stage 3 / high-stall converter, automatic oil cooler and xHP. Only “No” transfer-case variants are allowed: the Supra is RWD. Rebuilder approves torque, stall, duty cycle and core terms. |
| Six-speed manual | Toyota’s manual has a different gearbox/clutch and final drive. Quote a Supra-specific clutch, flywheel, release components, gearbox and shaft length/flanges. No BMW B58 clutch is assumed to fit; no automatic hardware or xHP appears in manual carts. At 1,000–1,200 WHP, approve the whole transmission solution. Toyota source. |
| Driveshaft | Kies DSS 610308 is a ZF8HP51 automatic candidate in the 800-WHP cart only. Manufacturer lists 1,000 HP, not 1,000 WHP; installer must approve torque/duty margin. Higher tiers require a stronger shaft quote. Manual cars require their own shaft specification. Include safety loop and approved joints/giubo. Manufacturer specification. |
| Axles / differential | DSS Supra SKU 510463 is an automatic candidate, subject to supplier resolution of conflicting BMW fitment copy. Do not substitute BMW SKU 510525 or Z4 hardware. Manual differential/axle interfaces and all high-load applications need approval; quote alternatives through Kies if required. |
Choose one tuning and fuel-control system
| System | Supra-specific specification |
|---|---|
| bootmod3 | Supra-specific license + port-matched Paul Johnson tuning candidate. PI/JDY/APX routes use REV2 with fuel-pressure and High Flow flex hardware after confirming CustomROM V2 and Supra wiring. The cable in the cart is for a compatible laptop connection; a suitable Ethernet adapter may be required. |
| MHD | MHD B58 license + MHD Wi-Fi adapter. Supra-specific custom tuning is separately quoted. PI routes use A90 Supra MHD+ complete controller kit with tuner-confirmed PT-CAN/PT-CAN2, firmware and AT/MT integration. Automatic and Open Wire manual flex kits are different at the DI-only baseline. |
| Fuel strategy | 500 WHP: tuner-selected fuel blend with DS25 DI upgrade; pump gasoline does not guarantee the number. 800–1,200 WHP: plan around an approved ethanol/race-fuel calibration, added PI and logged fuel-pressure margin. Do not use a generic OTS map for upgraded turbos/PI. Do not add methanol as an undocumented primary-fuel substitute. |
| Control & protection | Verify low-pressure and high-pressure fuel delivery, injector duty, lambda, ignition corrections, IAT, coolant/oil/transmission temperatures, overboost and PI-loss response. Above sensor range, fit and calibrate higher-range MAP sensors. Commission torque by gear and traction with the actual gearbox and tire. |
2-port Supra WHP builds
500 WHP · 2-port Supra
Start with a port-matched Pure650 for an upgraded-turbo 500-WHP target. The factory-turbo route is available for tuner review; it does not promise 500 WHP on pump gas. The six-port JDY kit is not an option for this head.

| Tuning | Supra bootmod3 or MHD B58 plus custom calibration and DME/ROM verification. Dedicated flex sensing, DS25 calibration and a tuner-selected fuel blend. JDY at 500 also adds the full PI/controller system. |
| Direct injection | Dorch DS25-350 · Supra/Z4 variant. DI-only at the stock/Pure 500 baseline; higher and JDY routes add a separate PI supply. Do not equate a pump model number with supported WHP. |
| Cooling | do88 Supra heat exchanger. Retain a healthy factory charge cooler for the stock/Pure baseline; monitor intake, coolant, oil and gearbox temperatures. |
| Crankcase / exhaust | Stock-location routes use Supra-specific BMR VTA catch can, FTP Supra charge pipe and AA Supra catted-downpipe candidate. Confirm intended use and catalyst duty. JDY includes its own can, piping and downpipe. APX needs a complete custom inlet/exhaust, wastegate, oil-line and heat-management quote. |
| Finish the package | Health checks, six plugs with tuner-set gap, required unlock, fuel and pressure safeties, labor, fluids, brake service/upgrade, wheels/tires and alignment. Every omitted or unavailable required item must be arranged before commissioning; cart subtotal is not complete installed cost. |
800 WHP · 2-port Supra
The two-port Pure850 is a stock-location candidate, but the reviewed evidence does not verify 800 WHP. For a strict target, the custom full-frame route includes an APX candidate and the required fabrication plan; it still needs engineering approval.

Research, dyno evidence and limits
A target is not a tested package.
The documented two-port Pure800 example made 742 WHP on E75 using EcuTek. The Pure900 manufacturer advertises 800+ WHP capability. Neither proves every recipe on this page. The four-digit Supra packages here are proposed engineering combinations; no exact 1,000/1,200-WHP result for these carts was verified.
- Toyota: US 2021 engine changes: Six exhaust ports replace two and compression changes from 11:1 to 10.2:1 in the US 2021 update. This is not a worldwide year-to-port lookup.
- Toyota: US 2023 manual transmission: The six-speed manual has its own clutch/gearbox design and final drive. Transmission and differential interfaces must be checked independently.
- Pure: two-port Supra dyno example: 742 WHP on E75 with a two-port Pure800, auxiliary fueling and EcuTek/Sam Badawi calibration. Evidence for that car only; not an 800-WHP bootmod3 or MHD result.
- Pure: current six-port PURE900 specification: Manufacturer advertises 800+ WHP capability. This does not validate a complete Supra package or a four-digit WHP target.
- JDY: B58 turbo-kit architecture: Six-port flange; included catch can, downpipe, charge piping and lines. Select the actual Supra and steering-side variant. HP marketing is not dyno WHP.
- Apex: APX 7685 specification: Compressor/turbine dimensions and housing choices for the custom candidate. No validation of these proposed 1,000/1,200-WHP Supra combinations.
- DSS: 610308 automatic driveshaft: Manufacturer identifies ZF8HP51 fitment and a 1,000-HP rating. Conflicting higher Kies copy is not used as a 1,200-WHP approval.
- Kies: Supra Pure850: Two- and six-port core choices; included inlet; 720+ WHP statement. Its name does not establish 850 or 800 WHP.
- Kies: REV2 requirements: Gen 2 B58 support requires CustomROM V2 and the correct DME unlock/software. Confirm the actual Supra ROM and wiring.
- Kies: Visconti complete Supra controller kit: A90 Supra MHD+ complete-kit variants exist. Current controller hardware, harness, port injection and transmission compatibility require confirmation.
- Kies: Supra AFS.800: Dedicated port-injection supply; 800 LPH is specified at 3 bar. Size from flow at operating pressure, fuel and voltage.
- Kies: Dorch DS25-350: Supra/Z4-specific connection option. Published E85 DI flow potential is 560 WHP without the pump-cam upgrade; higher recipes add PI.
- Kies: do88 MERA manifold: Includes auxiliary rail for compact injectors. Candidate injector dimensions, fittings and flow must be approved; no duplicate spacer rail.
- Kies: 5150 internal kit: Pro-Xtreme includes sleeves, pistons, rods, bearings and fasteners. HP labels are not stated as WHP; head parts, machining and assembly require a separate specification.
- Kies: Supra axle SKU 510463: Title/SKU identify Supra, but one fitment line names BMW. Supplier confirmation is required before using this candidate; manual fitment is not assumed.
- Kies: two-port Supra tuning evidence: The stock-turbo E50 figures vary within the listing, around 470–490 WHP; its 500+ examples add methanol. This guide does not describe 500 WHP as a universal pump-gas flash result.
Catalog variants and primary manufacturer/Toyota sources checked September 17, 2026. All product purchase links go to Kies; manufacturer links above are research references. No assumed drivetrain-loss percentage converts an HP advertisement into a WHP claim.
Finish the complete Supra package with Kies
All listed catalog parts start selected. The cart contains those selected products only. Required fabrication, unlisted components, labor and unresolved fitments remain in each build’s separate checklist; removing an unavailable part does not remove the need for it.
- Send VIN/market, actual port count, AT/MT, LHD/RHD, current parts, fuel, intended use and WHP/torque goals.
- Confirm turbo airflow, head/engine compatibility, fuel-system capacity, ROM/controller support and all safety strategies.
- Finalize manual clutch/gearbox or automatic converter/rebuild; correct shafts/axles, differential, mounts, tires and brakes.
- Approve all quote-only hardware, fabrication, cooling, machining, assembly, installation and dyno work before ordering the proposed package.
Product-specific competition-use restrictions apply to listed turbo and tuning hardware. Follow the selected product’s intended use. No WHP outcome, stock-component limit, reliability or warranty result is guaranteed.
