2024+ Mustang GT - Level 4 Package

2024+ Mustang GT Level 4 — Hellion Twin Turbo Package

This is the big one. Our Level 4 package for the 2024+ Mustang GT takes the S650 and turns it into an absolute animal — Hellion's Street Sleeper hidden twin turbo system, ID1050x injectors, professional installation, and our custom tuning to tie it all together.

Why Hellion? They've been turbocharging Mustangs since 2004, and the S650 Street Sleeper kit is the gold standard of bolt-on turbo systems: twin 62mm turbos (good for 1000+ HP, with turbo upgrades available all the way to 2000+ HP), 4-into-1 stainless turbo headers, a massive American-made bar-and-plate intercooler, Turbosmart wastegates and bypass valves, and American-made stainless piping backed by a lifetime warranty. It keeps your factory dual throttle body intake — something no supercharger kit can say — and it bolts on with no cutting, no oil pan tapping, and no K-member swap.

What you get:

• Hellion Street Sleeper hidden twin turbo system (twin 62mm turbos)

• Injector Dynamics ID1050x injectors — the only additional part needed on top of the kit

• Professional installation

• Custom Satera Tuning tuning

Starting at $18,999 installed and tuned.
