Frequently Asked Questions
What are the rarest upgrades in Forza Horizon 6?
Only a handful of FH6's 600+ cars can fit certain upgrades: the Motor and Battery slot, the Motor and Battery Swap, Roo Bars, rotary Rotors / Compression and the Restrictor Plate. This page lists every car for each.
What is a Motor and Battery Swap in FH6?
It's the electric equivalent of an engine swap — dropping a far more powerful motor-and-battery package (up to the 1893BHP Motor) into a compatible car for a huge power and PI jump.
Why can only some cars fit these upgrades?
These slots are tied to a car's stock configuration: EV parts only appear on factory electric cars, rotor upgrades only on rotary engines, and restrictor plates only on race-homologated cars.
Do these upgrades help with the Discover Japan Journal?
Yes — several Discover Japan Journal stamps ask you to install rare parts like these. Because each list is sorted cheapest-first, you can grab the most affordable eligible car and earn the stamp for the fewest credits.
How do I install a rare upgrade?
From your garage, open Upgrade & Tune → Custom Upgrade for a compatible car. If the car supports the part it appears in the matching upgrade category; cars not on these lists won't show the option.
