TNTSF68 Ball Bearing Drop-In Turbo — G30/G35 Fitment

When you're ready to leave stock power far behind, the TNTSF68 from True North Turbos is the flow king of the TNTSF lineup — a direct bolt-on replacement for the Garrett® G30 and G35 series that goes head-to-head with the G35-1050. Its 68mm (2.68") compressor rides the full 68x62mm G35-size turbine wheel and is rated to 1,110 crank horsepower, above the G35-1050's 1,050 HP rating — at hundreds of dollars less. Engineered and backed by Black Sheep Industries right here in Canada.

Features & Benefits

True Drop-In Fitment

Designed as a direct bolt-on replacement within the Garrett G30/G35 footprint, the TNTSF68 slots into your existing turbo location without custom fabrication. The mounting points, oil feed/drain connections, and housing options match what G-Series builders already plumb for — choose a T3 0.83 A/R turbine housing or dual V-band in 0.61, 0.83, 1.01, or 1.21 A/R.

Ball Bearing Centre Cartridge

The heart of the TNTSF68 is its precision ball bearing centre cartridge — a meaningful step up from journal bearing designs. You get quicker boost response off low RPM, reduced spool time, and a centre section built to handle the demands of high-power, high-hour builds. Water-cooled and oil-lubricated.

Rated to 1,110 HP at the Crank

With the right supporting modifications, the TNTSF68 is rated to support up to 1,110 horsepower at the crank. That's G35-1050 territory and beyond, making it a genuinely capable foundation for a full-send single-turbo build or a monster twin-turbo V8 combination.

Built and Supported in Canada

Designed and manufactured by True North Turbos, a Black Sheep Industries brand, the TNTSF68 comes with Canadian warranty coverage and direct-from-brand support. Whether you're building in Vancouver or Miami, you're buying from a team that stands behind their product.

Push your G30/G35-based build to its potential — the TNTSF68 is the drop-in solution for builders who aren't done yet.
