The TNT480 80mm T4 is the step up from the 76mm for builds with the fuel to use it — a street-able 1230-1285hp on a 6.0L or smaller pushrod V8, on the T4 flange your manifold already has.

It runs our own 96x88 turbine wheel, engineered over several years of testing to cut the backpressure associated with maxing out the standard BW 96x88 design. That means faster rotor acceleration and a wider usable band — gains of 115-235hp under 5000rpm and higher peaks over competitors we have dyno tested back to back.

The TNT4R line is universal. While the HP figures above are quoted on pushrod V8 applications, the same 80mm frame turns up on LS and big-block swaps, import six-cylinder builds, drag and no-prep cars, and diesel trucks running Cummins, Duramax or Power Stroke.

Replaces / Cross-Reference

The TNT480 is a direct bolt-on replacement for S480 turbochargers and other 80mm S400-frame units. Built on the same 400 frame, it uses the mounting hardware you already have:

  • Turbine inlet: T4 — fits your existing T4 manifold
  • Turbine discharge: 4.62" (117mm) half marmon — same flange and clamp
  • Compressor discharge: V-band, sized to your charge pipe
  • Oil drain: 50.8mm (2.00") bolt centre, 12AN port — same drain

Frequently Asked Questions

Is the TNT480 a direct replacement for an S480?

Yes. The TNT480 is built on the 400 frame, so it is a direct bolt-on replacement for S480 turbochargers. Your T4 manifold, half marmon downpipe flange, clamp, compressor discharge and 12AN oil drain all carry over.

What is the TNT480 96/88 rated for?

A street-able 1230-1285hp on a 6.0L or smaller pushrod V8, with 115-235hp gains under 5000rpm versus comparable competitor turbines. The same frame is used across gas, import and diesel builds.

Is this turbo built to order?

Yes. Every TNT480 is built to order.

Power ratings on this page are quoted in crank horsepower (HP). Figures previously published in wheel horsepower (WHP) have been restated using our in-house tested conversion — the hardware and its capability are unchanged.
