Send that turbo in to get the special treatment
Our porters thoroughly port both the hot AND cold side of the turbo. This is a great addition for any car setup. There will be a very noticeable increase in on/off throttle response and your entire powerband will shift to the left to get you that much needed down-low power for the ultimate street setup.
Imagine how quickly the exhaust will flow through your turbo now!!
For internal wastegate turbos, we reroute your exhaust gas to have a more efficient path out the wastegate hole.
