Frequently Asked Questions

Do I need custom fabrication?
Yes — you’ll need a custom dump pipe and intake to suit your vehicle/exhaust (OEM or 3-inch). The turbo, lines and hardware are included.
Is tuning required?
A professional ECU remap is highly recommended to make safe power and avoid limp mode, especially above stock boost.
What boost can it safely run?
The supplied actuator is set for performance use and the turbo is rated to around 35 PSI with the correct supporting mods, fueling and tuning.
Will it bolt to my factory manifold?
Yes — the unit is re-oriented for 1KD low-mount and includes brackets and flanges to suit the application.
Is this road-legal?
Modifications may affect compliance. This product is intended for off-road/competition use where permitted. Check local regulations.
