CTS Turbo BB-550 Hybrid Turbocharger for MQB Platform (2015-2020) DISCONTINUED

We are proud to announce the release of our premium ball-bearing hybrid turbo with stainless steel exhaust housing for 2015-2020 MQB platform vehicles. This high-performance hybrid turbo was designed by CTS engineers to fulfill the demand from customers who desire a direct-bolt-on turbo for their existing IS12, IS20 or IS38 turbocharger. Instead of trying to stuff a CHRA from a Mitsubishi into a factory housing; we re-designed and cast our proprietary STAINLESS STEEL exhaust housing to accommodate a larger turbine wheel. The compressor cover was also custom made and profiled to accept a very popular TD06 Billet compressor wheel, this ensures the turbocharger can reliably handle 30+ PSI. We upgraded the CHRA to a dual-ball bearing which is made from heat-resistant ceramic. Finally,  we finished the assembly by balancing it on a VSR high-speed balancer. This is a brand new turbocharger; no core or long wait times are required. Simply swap over your actuator and turbo outlet fitting for installation. Software tuning is required and it is available from most tuners. Features:

• Complete brand new turbocharger; no need for core to be sent it or purchased
• Dual ceramic ball bearing direct-fit CHRA (compatible with all factory oil and coolant lines)
• Billet MHI-style TD06 compressor wheel
• High performance 9 blade turbine wheel
• Stainless steel turbine housing
• VSR Balanced to exceed OE tolerances
• Compatible with most tuning solutions for hybrid turbos (United Motorsport, Eurodyne, COBB)
• Compatible with OE or replacement wastegate actuators (CTS-WGA-200 actuator recommended)
• Compatible with OE or aftermarket turbo inlets and turbo outlets
