The TNTSF58 is a direct bolt-on replacement for the Garrett® G30 and G35 series, running the same 58mm (2.28") compressor inducer size as the G30-770. Flowing 78 lbs/min, it's rated to 745WHP — roughly 870 horsepower at the crank — a full 100 hp above the G30-770's 770 hp figure while costing hundreds less. Fully ball bearing, water-cooled, and oil-lubricated.

Proven Across Platforms

• Subaru WRX/STI (EJ25): Expect 600+ hp, turning AWD thrills into outright dominance.
• Mitsubishi Lancer Evolution (4G63): Push past 600 hp with confidence.
• Toyota 2JZ: Unlock 600+ hp, perfectly balanced for street or strip.
• BMW N54/N55: Smooth power up to 600 hp.
• Ford Coyote 5.0 V8: Twin SF58s can propel you well beyond 1100 hp.
• Chevrolet LS/LT V8: Twin setups deliver 1100+ hp — serious flow for serious builds.

Drop-In G30/G35 Fitment

If your setup is plumbed for a G30 or G35, the TNTSF58 bolts straight in — no custom fabrication. Choose your turbine: the 60x55mm G30-size wheel for maximum response, or the 68x62mm G35-size wheel for more flow — each available with a T3 0.83 A/R housing or dual V-band in 0.61, 0.83, 1.01, or 1.21 A/R. The TNTSF58 is an independent True North Turbos unit, not a Garrett product — same footprint, more rated power, lower price.
