FAQ
Is this turbo a direct bolt-on?
No. It is a universal performance unit. You’ll need the correct manifold (T6 divided), oil feed/return, charge pipes, downpipe, and custom tuning.
What power range does an S476/87 with 1.10 A/R support?
With the right fueling and setup, S476/87 builds are commonly used in ~800–1100+ HP diesel applications. Results depend on engine, fuel, elevation, and tuning.
Can I use it as the low-pressure turbo in compounds?
Yes—this model is a popular atmospheric charger paired with an S300 high-pressure turbo for strong top-end flow.
Is it CARB legal for street use?
No. This turbo is intended for off-road/competition use and is not CARB exempt.
