TOMEI: THE ENGINE BUILDER'S ENGINE BUILDER
When professional engine builders need components they can trust absolutely, they reach for Tomei. Founded in 1968, Tomei Powered has spent over five decades perfecting the art of engine internals. Their camshafts, pistons, connecting rods, and valvetrain components are found in championship-winning engines worldwide. This isn't aftermarket—it's professional-grade.
The Tomei Poncam series became legendary among JDM enthusiasts. These bolt-in camshaft upgrades delivered meaningful power gains without requiring extensive engine modifications. For Nissan SR20, RB, and VQ engines, Toyota 4A-GE and 2JZ, Honda B and K series—Tomei developed cam profiles that balanced performance with reliability. Streetable power, not dyno queens.
Their forged internals set industry standards. Tomei pistons and rods appear in engines making 1000+ horsepower—and they survive. The engineering isn't flashy: precise metallurgy, tight tolerances, exhaustive quality control. These components don't announce themselves. They simply work, reliably, under extreme stress.
The Expreme Ti titanium exhaust line showcases Tomei's manufacturing excellence. Genuine titanium construction (not titanium-tipped steel) saves significant weight while delivering that distinctive titanium exhaust note. The signature blue/purple heat coloring develops naturally through use. These exhausts are as much jewelry as they are performance parts.
THE PHILOSOPHY: ENGINEERING OVER MARKETING
Tomei operates differently from many tuning companies. They don't chase trends or celebrity endorsements. Instead, they focus on continuous engineering refinement—making their pistons 2% stronger, their cams 3% more efficient, their exhausts slightly lighter. Incremental improvements that compound into significant advantages.
This engineering focus earned them OEM relationships. When manufacturers need prototype components or limited-production internals, they sometimes turn to Tomei's expertise. The same precision that builds race engines serves development programs.
For enthusiasts visiting the facility, Tomei represents pure engineering culture. The showroom displays decades of product evolution—you can trace how their SR20 cams developed from first generation to current, see the metallurgical progression of their pistons. It's a masterclass in iterative improvement.
