Forza Horizon 6: How to Complete the Supercharger CSC Mechanic Challenge

Forza Horizon 6's new Collection Journal introduces a variety of progression goals that encourage players to dive deep into the game's upgrade systems. Among the various automotive tasks given by Mei—the game's resident tuning expert—you will eventually run into a Mechanic Challenge requiring a "CSC" upgrade.

In Forza Horizon terms, CSC stands for Centrifugal Supercharger. Unlike standard superchargers that provide instant low-end power, a centrifugal unit functions similarly to a turbocharger, scaling its boost linearly with the engine's RPM. It is highly favored in lower-class racing builds for its excellent Performance Index (PI) efficiency.

If you are trying to check this requirement off your journal list, here is exactly how to do it without wasting unnecessary credits.

Step-by-Step Installation Guide

To complete the challenge, you need to purchase a compatible vehicle, head to a garage, and install the specific part under the aspiration conversions.

1. Travel to any Horizon Festival Site or your unlocked Player House.
2. Open the main menu, select Upgrades & Tuning, and then click Custom Upgrade.
3. Navigate to the Conversion category (located on the far right of the upgrade menu).
4. Select Aspiration Conversion.
5. Purchase and install the Centrifugal Supercharger (CSC).

Note: If the option does not appear immediately on a car's stock engine, it means that specific engine does not support it. You will either need to perform an engine swap first or use a different car.

Best Cars to Complete the Challenge

Instead of guessing which cars in your garage support a CSC setup, you can use these three specific vehicle pathways to guarantee a quick completion.

1. 2024 Ford Mustang GT (The Budget Option)

This is the single easiest and most cost-effective method available. You can buy the standard 2024 Mustang GT directly from the Autoshow for 45,000 Credits. Because its stock factory V8 naturally supports a centrifugal setup, you can navigate straight to the aspiration menu and install the CSC immediately without buying a expensive engine swap first.

2. Ford GT (The "Treasure Find" Method)

If you have already uncovered the Ford GT Treasure Find car, it can be used to clear this journal entry with a bit of extra garage work. Open the conversion menu and purchase the 8.4L V10 engine swap. Once the new engine is dropped in, the Aspiration section will unlock the Centrifugal Supercharger upgrade option.

3. DeLorean DMC-12 (The Classic Route)

The iconic DeLorean DMC-12 is another confirmed vehicle that accepts the CSC configuration. Equipping the centrifugal option on its powerplant will instantly trigger the journal credit, making it an excellent alternative if you already have the car sitting in your garage.

What Car Has A Supercharger Csc?

The easiest way to complete this challenge is to pick a vehicle that allows you to install a Centrifugal Supercharger directly onto its factory engine block without forcing you to buy an expensive engine swap first.

The most reliable, community-tested choices include:

• 2005 Honda NSX-R: This is the absolute best and most highly recommended car for the job. You can grab it directly from the Autoshow, head straight over to the upgrades section, and apply the CSC to the stock motor.
• 2005 Honda NSX-R GT: Functionally identical to the standard NSX-R for this challenge, its factory engine block takes the CSC upgrade immediately.
• 2017 Acura NSX: Another modern supercar choice where players have found the CSC conversion readily available in the menus.
• Dodge Viper (Various Models): Multiple generations of the Viper accept a CSC upgrade directly onto their stock, massive V10 layouts.

Common Pitfalls to Avoid

The upgrade system in Forza Horizon 6 has a few quirks that are currently tripping players up, causing them to lose credits on cars that won't activate the challenge:

• The 2024 Ford Mustang GT / Dark Horse Trap: Many players rush to use the new Mustang for this challenge. However, upgrading its stock motor equips a Displacement Supercharger (DSC), not a Centrifugal Supercharger (CSC). It will not give you credit for the challenge.
• Factory Forced Induction Issues: If a car leaves the factory floor with a twin-turbo setup or a traditional roots-style supercharger already installed, the game usually locks out the CSC option entirely. You cannot switch it over unless you perform a full engine swap first, which adds unnecessary costs to a simple challenge.
