Engineered Performance for Audi, VW, Porsche & Skoda

APR is pleased to present our 3rd generation A4 Stage 3 Turbocharger System. Now available for the B7 A4 2.0T FSI and our most powerful longitudinal application yet at 375hp and 352 lb ft of torque, APR's Stage 3 is the ultimate performance enhancement for your A4.
 
APR began developing complete turbocharger upgrade systems in 1998 and 1999 brought the release of APR's first Audi A4 turbocharger system, the APR 1.8T Stage III. To this day, the APR Stage III has progressed over nine different reiterations across sixteen different Volkswagen Automotive Group models from the Audi A4 and Volkswagen GTI to the Seat Leon and Skoda Octavia and has yet to be duplicated. Building upon almost ten years of experience, APR's engineers have developed our crowning achievement through the newest technology in turbocharged engines, the 2.0T FSI.

The Concept

The VAG 2.0T FSI has quickly proven itself as one of the most technological power plants available, even besting the previous generation 1.8T which is a tall order. While the engineers who developed the engine made fantastic gains in both efficiency and reliability, they left much to be desired with regard to power. The B7 A4 Stage III Turbo kit bridges this gap with uncompromising quality and extreme power. Stage III is the newest addition to APR's quality line of products for the A4.
 
While other companies use the terms "tuner" and "R&D" loosely, we at APR feel that quality products start with quality planning. We begin with an idea and study the feasibility of the product. As designers we put a strong emphasis on safety and reliability. APR engineers developed the Stage III kit using Pro Engineer Wildfire 3-D CAD software and a Faro Platinum CMM machine. Prototypes are then processed using the 3-D Systems SLA machine. This rapid prototyping procedure allows for quick-cast prototypes to ensure a perfect fitting final component. After the component has been verified correct, the final material cast can be run.
 

The Stage III utilizes one of the newest and most efficient turbos available. The Honeywell/Garrett turbos utilize the latest ball bearing design coupled with an integral wastegate and Inconel wheel. Make no mistake, these are not standard turbos retrofitted to ball bearing specs; they are the same type used in countless forms of motor racing such as the Audi R8 in the 24 Hours of Le Mans Series. APR is one of a few Garrett Engineering Houses in the US. We work closely with their engineers to design turbos that produce our desired performance level for each kit.
 

Other OEM components quickly reached their operational limits and were also redesigned. The increased flow necessitated a larger MAF Housing. The diameter of the intake tubing was also increased to accommodate the increased airflow. A new larger air horn was placed on the MAF to further increase velocity. A flow straightener was then added to keep turbulence to a minimum. A flow straightener seems like a small detail and is easily over looked by most companies. However, this "small detail" is an integral component of this system allowing the larger MAF housing to be properly utilized. Larger FSI fuel injectors are added to the kit to keep the fuel system within acceptable parameters and to deliver the required fuel to the engine from the included High Pressure Fuel Pump.
 

APR engineers write their own proprietary data logging software and analysis programs. This tuning software, combined with APR's Dynapack chassis dynamometer and environmentally controlled dyno lab, allows a degree of precision never before seen in the aftermarket industry. Our dyno tuning allows us to tune to any RPM at any load level. This equates into the smoothest, most powerful tuning available. Our software, as with our hardware, is equally ahead of the competition. It's a rare combination to find a tuning company that engineers both the software AND the hardware for their systems. The advantage of designing hardware that is built to utilize our specific software is obvious. OUR hardware working with OUR software is what comprises a truly engineered "system" and not just a conglomeration of parts.
 
No other company has the switching capabilities or the programming capabilities that we have. From home programming to industry leading EMCS, our products set the bar in which all others are measured.
 

The Components

Below are components included with the 2.0T FSI Longitudinal Stage III. Because this kit is so extensive, it would be impossible to highlight all of the items that are included. The APR 2.0T Stage III kit includes ALL components needed (except a catback exhaust, upgraded intercooler, Carbonio Carbon Fiber Airbox, oil, and coolant) to take a car to 375hp/352lb-ft.
 

Note: This kit is supplied with a Test pipe. In order for this kit to comply with Australian laws, the test pipe needs to be modified to include a cat. We recommend installation of a 200 cell metal cat (Additional cost)
