ATP Turbo GTX3576R

This fast-spooling turbocharger features dual ball-bearing technology and is ideal for those looking to make 600+ horsepower. This is a direct bolt-on turbocharger with an external wastegate provision on the exhaust housing for those who want optimal boost control, with the scream of the external wastegate. 

Note that although this turbocharger is a direct bolt-in unit, it is recommended for those with a built engine in case you're trying to maximize the power, boost, and performance.
