Major Maintenance, Custom Fab & Bulletproof Reliability Upgrades!
Subaru Forester XT S-Edition just received the ultimate treatment at Fuji Performance.
We didn’t just tick off the major service items—we completely transformed the exhaust system and threw on some critical engine bay upgrades to ensure this EJ stays healthy under boost.
Here is everything we wrapped up on this build:
Engine Bay & Reliability Upgrades
* Custom Catch Can Setup: Installed a dedicated catch can with brand new breather hoses and heavy-duty clamps to keep blow-by out of the intake, ensuring only clean air enters the combustion chamber.
* Quick-Disconnect Negative Battery Terminal: Fitted a quick and easy negative terminal disconnect switch—perfect for easy storage, working on the car, or a quick reset without fumbling for wrenches.
* Passenger-Side Cylinder 4 Cooling Mod:Cylinder 4 sits right at the back of the passenger side where engine heat gets trapped. We installed a proper cooling mod using premium FTF AN fittings to equalize coolant flow and protect against catastrophic ringland failure
Full Custom 76mm (3") Stainless Steel Exhaust Fabrication
We fabricated a completely restriction-free, high-flowing masterpiece from front to back:
* 76mm S/S Bellmouth Downpipe: Allows for smooth, optimal exhaust gas expansion right out of the turbo hot side.
* Full 76mm Stainless Steel Piping: Straight-through flow to eliminate backpressure.
* 76mm S/S Resonator: Welded in to eliminate nasty cabin drone while keeping the tone incredibly deep.
* Dual 76mm S/S Free-Flow Rear Silencers: Performance twin mufflers for that perfect balance of sound and exhaust flow.
* Leak-Free V-Band Flanges: Used high-quality V-band clamps throughout the system for a perfect seal and effortless removal down the road.
* Dual 101mm (4") Tips: Filling out the rear bumper perfectly for a massive, aggressive look.
The Major Engine Service & Timing
* Complete Cambelt Kit & New Water Pump: Brand new timing components installed for total peace of mind.
* Engine Flush & Premium Lubricants: Flushed out the old oil and filled her back up with high-performance Motul 10w60 Fully Synthetic Oil, a fresh OEM Oil Filter, and a new sump washer.
* Ceratec Oil Additive: Added Liqui Moly Ceratec to provide advanced anti-friction and wear protection for the internals.
* Cooling Overhaul: Brand new top and bottom radiator hoses, topped up with fresh, high-grade anti-freeze.
* Tune-Up Essentials: Crisp new spark plugs, a fresh OEM Air Filter, and a new OEM Cabin Filter for clean interior air.
Drivetrain Service
* Gearbox & Rear Diff: Drained and filled with premium Liqui Moly Oil for silky smooth shifting and bulletproof drivetrain protection.
Fuji Performance Tip: A catch can is essential on turbo Subarus. Over time, oil v***rs from the crankcase breathe back into your intake, lowering your effective fuel octane and increasing the risk of knock. Catching that oil v***r before it hits the intake keeps your engine running crisp and safe!
This S-Edition looks mean, sounds absolutely beautiful with the custom exhaust, and is mechanically locked down from top to bottom. Ready to hit the streets!
