CTS Turbo

Model #CTS-TR-1015-38


Shopper Award

We heard your demands and we are happy to unveil our latest premium hybrid turbo with a stainless steel exhaust housing specifically designed for MQB platform vehicles.

At CTS, we received a massive amount of requests from our customers seeking a budget-friendly-direct-bolt-on turbo upgrade for their existing IS12, IS20, or IS38 turbochargers. To meet these demands, we have designed our very own journal bearing turbocharger upgrade.

The goal was to develop a turbo with a strong power up top compared to the JB-600. Our engineers decided to keep the journal bearing CHRA from our popular IS38 turbocharger and spice it up a bit, to match the larger wheels and a performance-oriented nature of this upgrade. The thrust bearings and thrust collars were increased by 2mm to accommodate the extra load. The oil passages were increased by 0.72mm to allow the most efficient hydrodynamic wedge when the turbocharger is in operation. This turbocharger was extensively tested on our own and our partner vehicles around the world, at different altitudes and different climates.

Long story short: this turbocharger is capable of delivering approximately 650 crank hp, around 550-600whp on E85 and 460-480whp on pump 93 octane**. The turbocharger is designed for street use, while it is a bit laggy compared to our JB-600 you get the benefit of a big power up top.

We recommend to keep the boost within 29-33psi, less if you're limited by fueling or stock engine. Do not exceed the recommended boost range, as it will reduce efficiency.

What is CTS Turbo?

CTS Turbo is a manufacturer and wholesaler of performance automotive parts, specializing in late-model Audi, BMW, and Volkswagen vehicles. The company also offers products for Toyota and MINI Cooper models. All CTS Turbo products are TIG welded and constructed using T304 stainless steel.

CTS Turbo prides itself on being a leader in the industry, offering an unparalleled level of high-end products, technical know-how, and customer service. The brand has everything you need to enhance the performance of your car; that includes cold air intakes, catch can kits, turbo kits, and performance exhaust systems. CTS Turbo’s team of skilled engineers and fabricators are dedicated to constantly developing new performance parts for your car to take it to the next level.

CTS Turbo Catch Cans

Oil catch cans are simple devices that can greatly benefit direct-injection motors. They are used to prevent oil and other contaminants from entering the intake manifold and clogging up the intake valves with buildup. Oil deposits on the intake manifold and valves can reduce performance and cause poor fuel mileage. 

CTS Turbo Intakes

Cold air intakes help deliver a smooth entry of cold air directly into the engine to improve performance and acceleration. Using mandrel-bent aluminum intake piping, CTS Turbo reduces unwanted turbulence within the pipes, which would otherwise reduce airflow into the engine. High-flow air filters utilize a cone design for better engine breathing and a great sound too.

CTS Turbo Exhausts

All CTS exhausts are hand TIG-welded using the finest T304 seamless stainless steel designed for both street use and track applications. Other systems use lower-quality materials causing them to crack and decay over time. CTS’ exhaust systems also deliver a tantalizing aggressive sound that produces several smiles per mile. 

CTS Turbo Downpipes

Downpipes are the perfect high-performance replacement for the factory downpipe, which rob your vehicle of its potential power. CTS Turbo’s downpipes feature a stainless-steel construction and built with maximum performance in mind. They are available in race-spec and street-spec varieties featuring Magnaflow catalytic converters.
