***CTS Boss 700 Turbo Upgrades for the MQB family***

Our goal with all turbocharger upgrades is to keep the factory flanges and remain close to 100% bolt on like it was intended.

TPC now offers something that nobody else does!

Your Boss 700s can be upgraded to either a GT/G30-900 or a full on GT/G35 turbo.

But that’s not all. You now have the option of going even bigger then a GT35 62mm turbine and fit a bigger PTE 66mm turbine… Yep that’s right. We can go as big as a 6266 in the CTS housings.

-That being said. For the customers that would like a 6466 or 6766 in the Boss hot side with external waste gate provision, please contact us for more info. -

For these upgrades the TPC team will perform CNC work on the turbine and compressor housing to fit the wheels of your choice. This makes it for a great upgrade for users that want the best power to cost ratio while attempting to keep it all bolt on.

All our turbos get the in house low and high speed balancing treatment to ensure the best reliability when boosting your car to it’s limits.
