MQB Turbo Upgrade Kit for MK7 GTI, Golf R & Audi 8V

Note: superseded by CTS-TR-1010-76. CTS Turbo built this as the first genuinely bolt-on big-turbo upgrade for the MQB platform — a modular BOSS (Bolt-On Speed Solution) package good for upwards of 600hp with the long-term reliability of a real Garrett Gen2 GTX turbocharger.

Why the in-house housing matters

The Garrett Gen2 GTX core sits in a CTS proprietary exhaust housing, cast and machined to bolt up to any exhaust downpipe. The scroll area targets roughly 0.63 A/R for sharp boost response with no added restriction. Dropping a bigger turbo into a stock housing simply does not flow — which is exactly why CTS made their own. A custom wastegate solenoid bracket plus oil and water lines round out simple installation and tuning, and proprietary molded silicone hoses link the turbo to your outlet pipe and intake.

Compatibility

• Runs with a CTS Turbo intake; other intakes may work but cannot be supported
• Use a CTS Turbo or other billet diverter/blow-off valve; factory DV works with a harness extension
• OEM or CTS Turbo outlet pipe only at this time
