KIES MOTORSPORTS, LLC — TERMS AND CONDITIONS OF PURCHASE AND SALE

Fitment comes before the horsepower number

Driveshafts & axles by chassis

Choose the chassis and drivetrain before ordering shafts or axles. Sharing a B58 or S58 engine does not establish interchangeability. These references apply across all four WHP tiers.

Choose the route for your power target

Compare bootmod3/MHD and Pure/JDY at the lower tiers. At 1,200 WHP, both tuning platforms use the dedicated Custom Race Package; its hardware selection is not restricted to one turbo brand. At 1,000 WHP it also replaces the unsubstantiated Pure-only option with a lower-output calibration. All proposed combinations require final fitment and dyno validation.

Choose your tuning platform

Choose one platform. A flash license, an unlock and a custom calibration are separate purchases. Turbo brand does not determine the tuning platform.

Supporting mods every tier starts with

All tiers below include this foundation and one tuning-platform package. Tier lists show the additional hardware. Items marked “quote” are still part of the build and must be itemized by Kies before it becomes an orderable package.

500 WHP · S58

Keep the factory twin turbos for a sensible 500-WHP baseline. Establish what the specific M2/M3/M4 already makes, then request a controlled pump-fuel calibration if needed. Upgraded Pure or JDY turbos here are optional preparations for a later power target.

500-WHP supporting-parts specification

Read with the foundation and your selected tuning package. Choose one turbo path; avoid duplicate included components.

800 WHP · S58

An ethanol-fueled upgraded-turbo build with controlled torque, added fuel capacity and repeated-run cooling. The proposed hardware works as a system; the brand of the turbo does not remove the need for port-injection controls or a gearbox plan.

800-WHP supporting-parts specification

Read with the foundation and your selected tuning package. Choose one turbo path; avoid duplicate included components.

1,000 WHP · S58

Choose the JDY 7275 route below or the Custom 1,200-WHP Race Package with a lower-output calibration. Both approaches use a built-engine plan and transmission/driveline specification matched to torque.

1,000-WHP supporting-parts specification

Read with the foundation and your selected tuning package. Choose one turbo path; avoid duplicate included components.

1,200 WHP · S58

The turbo selection

DOCRace S58 kit / Precision 7475 Next Gen Sportsman. Select the 1.5-inch Schedule 40 manifold and “Yes Please. Vent to atmosphere” catch-can option. This adds a DOCRace/Precision route beyond the JDY and Pure turbo choices. [S5] [S6]

The exact turbo, housing and operating point must satisfy the 1,200-WHP airflow requirement. An advertised HP rating is a component selection clue, not proof of wheel output. Any substitution must include a compatible manifold, downpipe, oil plumbing and boost-control plan.

Choose one calibration package

Shared hardware bill of materials

Install the following with one calibration package above. Quantities refer to kits unless individual pieces are specified. Keep the inspection, maintenance and validation foundation in the work order.

Why this is a 1,200-WHP target package

The DOCRace/Precision combination is a new proposed route. Precision’s 7475 specification and the Kies kit options support the component selection, while the separate JDY/bootmod3 Kies car demonstrates that an extensively supported S58 has reached 1,218 WHP. That car does not validate this DOCRace package or its MHD calibration. [S1] [S5] [S6]

Documented turbo alternative: JDY 7275 / recirculated / 0.96 A/R kit follows the turbo family used in the 1,218-WHP reference. If selected, use the JDY-specific installation hardware and required JDY catch can in place of the DOCRace turbo/catch-can assembly. Keep a separately validated calibration for either tuning platform. [S1] [S3]

X3 M / X4 M parts and fitment references

Kies product configurations were checked October 14, 2026. Manufacturer application references support the chassis-specific selections; they do not verify the completed WHP package.

Research & source notes

Evidence standard: measured vehicle results, manufacturer capability statements and proposed engineering selections are identified separately. Turbo model numbers, pump names and unspecified “HP” ratings are never converted into WHP. No fixed drivetrain-loss percentage is applied.

1. [S1] Kies S58 dyno build: 1,218 WHP
   JDY 7275, built engine, Pure transmission, AFS.800, 1750-class port injectors, bootmod3/REV2, HCP, GSC cams and E85R. Result belongs to this car.
2. [S2] Pure: current S58 Stage 2+ specification
   Current manufacturer description says 900+ WHP. Older Kies collection copy says 1,000+; use the current manufacturer statement and request a documented 1,000-WHP combination.
3. [S3] JDY: S58 single-turbo kit
   Kit hardware, manifold sizing, required catch can and heat management. Use the actual Kies variant selection for ordering.
4. [S4] Kies: S58 engine build kit
   Stage labels use HP without a stated wheel/crank basis. The listing recommends additional cylinder sealing above 1,000 HP; builder must size for the WHP goal.
5. [S5] Kies: DOCRace S58 kit and selected options
   Live variant 42428352364629 selects PTE7475 Next Gen Sportsman, 1.5-inch Schedule 40 runners and the VTA catch-can option. This is the proposed alternative package’s turbo kit. Descriptive copy contains other turbo choices; the selected variant governs the order.
6. [S6] Precision: Next Gen Sportsman 7475
   74-mm compressor / 75-mm turbine. Precision describes upwards of 1,350 HP; the Kies option title says 1,400 HP. Neither is a 1,200-WHP dyno result. Confirm the exact revision, turbine housing and required airflow with the tuner.
7. [C1] Kies: REV2 requirements and contents
   Gen 2 B58/S58, CustomROM V2 requirement, pressure/flex options, harness and MAP sensor contents. Ordinary platform unlock and CustomROM V2 support are separate checks.
8. [C2] MHD: current supported features
   MHD+ DME port-injection control and custom safeties vary by engine and software version. Feature availability must be checked against the actual ROM.
9. [C3] Kies: Visconti S58/B58 controller package
   Full-kit controller, harnesses, pressure and ethanol sensor contents. Rail/manifold and manifold fuel feed are separate; competing flex kits are not integrated.
10. [F1] Kies: Precision Raceworks AFS configurations
    AFS.800 is a two-pump auxiliary system; its name describes nominal fuel flow, not an 800-WHP ceiling. Catalog flow is at 3 bar, not at peak rail pressure under boost.
11. [F2] Injector Dynamics: ID1750-XDS data
    Universal 1750.34.14.14 configuration, fuel compatibility and pressure-dependent characterization. Nominal flow is 1,728 cc/min at 3 bar; product family naming is not exact flow.
12. [T1] Kies: HCP S58 stock-turbo map
    Reports 600–640 WHP on 93+ octane and 700–740 WHP on E50 with specified supporting mods. It is explicitly a stock-turbo bootmod3 product, not a JDY/Pure custom tune.

Finish the bill of materials with Kies

The tier cart builders add the selected catalog parts with live price and availability checks. They do not include unchecked parts or quoted work. A parts cart is not a complete installed or dyno-validated package. The following must be resolved in a Kies build quote:

• Confirm VIN/chassis, fuel availability, target torque and use. Quote exact variants and current lead times; active/orderable is not proof of physical stock.
• Itemize omitted small parts: correct turbo installation gasket/seal/bolt set, air-filter/inlet hardware, boost solenoid and hoses, high-range sensors/adapters, rail fittings and pressure-reference plumbing.
• Confirm injector/manifold dimensions and provide the combined DI+PI fuel budget at the chosen ethanol content, differential fuel pressure and duty cycle. At high boost the pump sees rail pressure above base pressure; free-flow/catalog figures are insufficient.
• Name the custom tuner, approved ROM/controller firmware and scope: flex fuel, PI fault handling, pump control, electronic/pneumatic wastegate strategy, torque reporting and dyno revisions.
• Quote engine and transmission labor, machine work, sealing, valvetrain work, converter, drivetrain reinforcement, installation, fluids and dyno validation. These cannot be costed accurately from engine name and WHP alone.
• Select tires and brake hardware by the actual wheels, calipers, vehicle weight and intended use. Include track-required rollover protection, harness/seat system, fire equipment and other safety equipment through a separate race-preparation review; their Kies availability was not verified.

Provide Kies with the page, desired route, VIN, existing modifications and intended fuel to finalize the bill of materials. The cart builder shows a selected-parts subtotal; the complete project cost also includes the quoted work.
