When you're building a Subaru—whether it's a forged daily, weekend track weapon, or full-send competition car—the power's easy. Anyone can make boost. The hard part is making it last.
At Roo Racing, we back brands that go the distance. And when it comes to serious Subaru engine support, Fuji Racing is the real deal.
Why Fuji Racing?
Fuji Racing was born in the UK under the ICP Imports banner, built by people who know Subaru engines inside and out. They weren’t chasing clout or trying to slap their logo on generic parts—they were solving real problems for real engine builders.
From blown head gaskets to oil starvation to inconsistent injector flow, Fuji Racing set out to engineer solutions that work. The result? A brand that's earned its place in engine bays around the world—and a permanent home here at Roo Racing.
Built for Boost, Made to Hold It
You don’t bring Fuji Racing into your build to look pretty (even though their billet finishes do look damn good). You bring them in to solve problems before they start:
🔩 14mm Cylinder Head Stud Kits
The factory head studs were never meant to see the boost pressures and power levels modern EJ builds can push. Fuji’s 14mm stud kits, made from heat-treated 8740 chrome moly, offer up to 30% more clamping force than OEM. That’s the difference between sealing power and chasing coolant leaks.
Tested in builds pushing 500+ bhp and over 1.9 bar, these studs are a must-have once you’re past basic bolt-ons. They hold it down—literally.
🛢 Thermostatic Oil Sandwich Plates
Oil temps too cold on startup, too hot on a track day? Fuji Racing’s billet oil sandwich plate includes a thermostatic valve that keeps temps in check. Whether you’re dailying or sending it, oil stays in the goldilocks zone.
🧪 High-Flow Injectors (550cc – 1650cc)
With ethanol and flex-fuel builds more common than ever, injector flow consistency becomes mission-critical. Fuji Racing’s Bosch Motorsport top-feed injectors are flow-matched to ±1%, giving you confidence under WOT and clean idle tuning every time.
🧰 Oil Baffles, Sump Mods, and Anti-Surge Kits
No one wants to be that guy spinning a bearing at the track. Fuji’s sump baffles and anti-surge plates reduce oil slosh and keep pressure consistent when it matters. Your bottom end will thank you.
🎯 Every Detail Counts
It’s the small stuff, too. Clear timing covers for visual inspo. Braided lines. Billet fuel rails. Lightweight pulleys. Everything is made to fit, function, and flow better than the factory gear ever could.
Why Roo Racing Loves Fuji
We’ve seen the difference first-hand. Fuji Racing parts don’t just fit—they work, and they work well. We recommend them to customers chasing performance and reliability. From garage-built street cars to dyno queens, Fuji Racing holds up where others tap out.
And thanks to our relationship with Fuji, we keep a solid range stocked locally here in Australia—no long wait times or international shipping dramas.
Built Right, Backed Hard
A fast Subaru is fun. A fast Subaru that stays together? That’s a weapon.
If you’re planning a serious build, don’t skip the support gear. Fuji Racing gives your engine the backup it needs to keep pushing, lap after lap, launch after launch.
