Forza Horizon 6 has taken the racing community by storm with its stunning depiction of Japan's diverse landscapes, from neon-lit urban streets to winding mountain passes. Among the most exciting discoveries hidden within this open-world playground is a true track legend: the 2005 Mitsubishi #1 Sierra Sierra Enterprises Lancer Evolution Time Attack. This aero-heavy, high-grip monster is a dream for anyone looking to dominate the game's challenging touge runs and technical road circuits.
However, you won't stumble across this machine by accident during your initial hours of exploring. True to the Horizon tradition, this iconic Evo is tucked away inside a hidden barn, and unlocking it requires a mix of specific campaign progression and precise navigation. If you are tracking down this racing beast, here is exactly how to unlock the rumor and where to find the barn.
Requirements to Unlock the Barn
Unlike previous entries in the franchise where you could occasionally trigger barn finds simply by driving near them early on, Forza Horizon 6 implements a stricter progression system. To get the specific "Barn Find" rumor to pop up on your map, you need to put in some legwork within the campaign menu:

• Collector's Journal Level: You must reach Level 6 (Adventurer status) specifically within the "Discover Japan" campaign track.
• Campaign Progress: Keep accumulating progression points. The fastest way to stack these up is by tackling core story missions, competing in touge and traditional road races, and investing your credits into purchasing houses across the map.
• The Purple Stamp: Meeting these milestones will eventually reward you with a Purple Stamp. Earning this stamp is the ultimate trigger that puts the rumor circle on your map and allows you to actually interact with the barn structure.

Note for completionists: If you drive to the location coordinates listed below before obtaining the Purple Stamp, the barn will simply appear as an inactive, locked building. Make sure you check your Discover Japan progression first!

Step-by-Step Location Guide
Once you have the Purple Stamp and the rumor area lights up, it's time to head out into the hills. The vehicle is hidden away in the scenic Shimanoyama region, specifically on the northern side of Narai-juku. Follow these steps to drive right up to the garage doors:

1. Travel to Narai-juku: Set your waypoint or fast travel to the historic town of Narai-juku. You will want to position yourself on the northern outskirts of the main town area.
2. Locate the Off-Road Trail: Look directly above the main town area on your map for a distinct dirt/off-road trail. Get your favorite off-road or rally build onto this path and start driving eastward.
3. Watch for the Right Fork: As you wind your way east along the dirt trail, keep a close eye on the right side of the track. You are looking for a subtle, narrow exit path that splits off to the right. It can be easy to miss if you are carrying too much speed.
4. Claim the Barn Find: Turn onto this right-hand fork and follow the path all the way to its absolute end. The trail terminates right in front of a secluded, weathered barn hidden among the trees.

Drive up to the doors, and the classic cutscene will trigger, kicking off the restoration process for your brand-new Mitsubishi Time Attack Evo. Give your mechanic some time to clean her up, and before long, you will have one of the sharpest-handling cars in the entire game sitting in your garage, ready to slice through the Japanese countryside.
