For a reasonable assurance of motor longevity we recommend no more than 8 psi on a Mustang GT and 10 psi on Boss 302 vehicles. On the GM 1500 Series Trucks 8-12 psi are good numbers to shoot for providing you also purchased our 3″ exhaust.
GT Vehicles require the installation of a Boss 302 intake manifold. A catch-can setup is also recommended, but not required on low boost vehicles. On the GM 1500 Series Trucks nothing else is required to install, but our 3″ exhaust is recommended.
The entire system has a 1 year warranty on every component (Turbochargers, Wastegates/Blow-Off Valve, Plumbing, Intercooler). The piping has a lifetime warranty against cracking, warping, corrosion and deflection.
Garrett Turbochargers make as much, and more, power than any other turbocharger brand on the market. On top of that they are BAR NONE the most reliable turbochargers available. We sell the best Turbo Kits, so naturally we only use the best Turbochargers!
