The TNTSF62 is a direct bolt-on replacement for the Garrett® G30 and G35 series, built for serious power. Its 62mm (2.44") inducer matches the G30-900 and G35-900 compressor size — but with a larger 82mm (3.23") exducer, it flows 91 lbs/min and is rated to 935 crank horsepower. That out-rates the 900 HP figure of both Garrett counterparts, at hundreds of dollars less. Stainless steel construction, fully ball bearing, water-cooled, and oil-lubricated.

Drop-In G30/G35 Fitment
If your manifold and downpipe are plumbed for a G30 or G35, the TNTSF62 bolts straight in — no custom fabrication. Choose your turbine: the 60x55mm G30-size wheel for response, or the 68x62mm G35-size wheel for 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 TNTSF62 is an independent True North Turbos unit, not a Garrett product — same footprint, more rated power, lower price.

Frequently Asked Questions
What is the TNTSF62 rated for?
935 crank horsepower, with a 91 lbs/min flow rating.
Is the TNTSF62 a direct drop-in for the Garrett G30/G35?
Yes. It's a stainless steel direct bolt-on replacement within the G30/G35 footprint — fully ball bearing, water-cooled, and oil-lubricated — installing without custom fabrication.
How does the TNTSF62 compare to the G30-900 and G35-900?
All three run a 62mm compressor inducer, but the TNTSF62's larger 82mm exducer flows 91 lbs/min for a 935 HP crank rating — against the Garrett units' 900 HP — at a significantly lower price.
Is the TNTSF62 a Garrett turbo?
No. It's designed and manufactured by True North Turbos, a Black Sheep Industries brand. "G30/G35 fitment" refers to compatibility only.
