TOMEI Powered: The Ultimate Engine Specialist from Japan
In the world of JDM performance, TOMEI is a name that commands absolute respect. Since 1968, TOMEI POWERED has maintained a singular focus: the engine. Their "Engine Specialist" philosophy has driven them to develop components that define JDM tuning for the Nissan RB, SR, and Subaru EJ platforms. From precision-ground camshafts to ultra-lightweight titanium exhausts, TOMEI parts are engineered to perform under the harshest racing conditions. ATOMIC-SHOP Ukraine is an official partner, providing enthusiasts with direct access to Japanese racing excellence.
For high-performance builds in Ukraine, TOMEI components are the benchmark for quality and weight reduction. At ATOMIC-SHOP, we know that serious racers choose TOMEI Expreme Ti exhausts not just for the incredible sound, but for the massive 15kg+ weight savings over stainless steel systems—a critical factor for cornering speed and agility.
Comparison Table: Expreme Ti Titanium vs. Standard Exhausts
| Feature | Standard Stainless Steel | TOMEI Expreme Ti (Titanium) |
|---|---|---|
| Weight (Typical System) | 40 – 50 lbs | 9.7 – 11.5 lbs |
| Material Grade | SUS304 Stainless | Grade 1 Pure Titanium |
| Exhaust Note | Deep and Muffled | High-pitched, Metallic "Race" Tone |
| Thermal Management | Holds Heat (Heat Soak) | Rapid Heat Dissipation |
| Resistance | Oxidizes over time | Immune to corrosion and rust |
Camshaft Engineering: Poncam & Procam Series
The core of TOMEI’s reputation at ATOMIC-SHOP is their camshaft development. The Poncam series is designed as a high-performance "drop-in" solution, compatible with stock valve springs and requiring no ECU remapping for immediate gains. For high-end competition engines, the Procam series offers professional-grade lift and duration profiles to maximize turbo efficiency and top-end power.

| Nissan SR20DET / RB26 | Poncam Camshafts | Optimized valve timing for street/track response |
| Mitsubishi Evo 8-10 | ARMS Turbo Kits | Direct bolt-on power with OEM-like reliability |
| Toyota 86 / Subaru BRZ | UEL Header (Expreme) | Restores the "Subaru rumble" and increases torque |
FAQ: ATOMIC-SHOP Insights on TOMEI Products
Is the TOMEI titanium exhaust too loud for daily use?
The Expreme Ti is designed as a competition-grade exhaust, so it is louder than standard systems. However, ATOMIC-SHOP stocks the full kits, which include a removable inner silencer. With the silencer installed, you can enjoy a more subdued volume for road use without sacrificing the titanium aesthetic.
Why choose TOMEI Head Gaskets?
TOMEI utilizes a multi-layer steel (MLS) design with a unique "Super Grommet" seal. This provides superior combustion chamber sealing under extreme cylinder pressures. Our team at ATOMIC-SHOP recommends TOMEI gaskets for any build targeting 400+ HP to prevent head gasket failure.
What makes TOMEI oiling solutions critical?
JDM engines like the RB26 and SR20 often suffer from oil management issues at high RPM. TOMEI oil gallery orifices and baffled oil pans (available at ATOMIC-SHOP) ensure that oil stays in the sump and flows correctly to the head, preventing catastrophic bearing failure during high-G cornering.
