Transverse 2.0T FSI Stage III Turbo Kit
The award winning APR 2.0T FSI Stage III is now available to the public! Own the same turbo system found in Volkswagen of Americas R-GTI Concept Car and APRs VoA Tuner Challenge Winning GTI!

APR began developing complete turbocharger upgrade systems in 1998 and 1999 brought the release of APRs first VW/Audi turbo upgrade 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, APRs engineers have developed our crowning achievement through the newest technology in turbocharged engines, the 2.0T FSI.

The APR 2.0T FSI Stage III delivers a powerful, refined, turnkey solution from the expertly recalibrated engine management system to the investment cast inconel exhaust manifold and upgraded FSI fuel injectors and fuel pump. Featuring the APR/Garrett Honeywell Ballistic Series GT2871APR Ball Bearing Turbocharger, the APR Stage III brings your Fast to 382 daily drivable horsepower and 332 pound feet of neck snapping torque.

Tested by Professional Race Car Drivers Randy Pobst and Ian Baas across six road courses throughout the Continental United States for over a year, the APR Stage III operates as if intended by the factory with flawless drivability your Grandmother can drive and reliability you would trust to your spouse on a long drive alone. Rock solid idle and amazing part throttle operation takes the weekend trailer queen out of the highly modified aftermarket and provides luxury car daily driving during a trip to the office and pure, powerful, consistent performance while turning laps on the race track. Intense durability testing at the most demanding road courses in the country allowed an engineering solution that will perform lap after lap and commute after commute. APR, once again, has delivered unparalleled Enhancement to Your Driving Experience! The highlights of the kit include the following:

• APR Investment Cast Inconel Exhaust Manifold

Longitudinal 1.8T Stage III Turbo Kit
APR Stage III is our cutting-edge turbo upgrade for your Longitudinal 1.8T. We at APR have worked long and hard to bring you the finest 1.8T upgrade available. Both kits are made with the best materials and engineering available, from the exhaust manifold to the hose clamps. APR Stage III is offered in a 280hp version. Our Stage III kit consists of the following components:

• APR Investment Cast Inconel Exhaust Manifold
• Garrett/Allied Signal Ballistic Series Ball-Bearing Turbocharger
• APR High Flow Catalytic Converter
• APR Custom Cast Urethane and Silicone Intake Hoses
• APR High Flow Fuel Injectors
• All Associate Plumbing and Hardware

The most important part of the Stage III kit is the exhaust manifold. APR has spent enormous time and resources developing the turbo manifold. The exhaust manifold has been designed in Pro/Engineer 20, a 3-D modeling package and validated extensively on the computer using Exa Powerflow, a CFD analysis program. By performing a computational fluid dynamics analysis, we were able to study exhaust flow, pressure drops, and fluid flow through the exhaust manifold. Multiple computer simulations were done to prove the design before we even had a physical manifold in our hand.

Once the manifold was fully passed on the computer we had the exhaust manifold CAD file transferred to a rapid prototyping machine. A polycarbonate exhaust manifold was cast from the prototyping machine. With this plastic manifold we were able to mock everything up in the test vehicle before proceeding to the next process.

From the polycarbonate piece we were able to cast a metal piece for prototyping. The metal used for the prototype and the production manifold is Inconel 625. Inconel is a very high quality (yet expensive and difficult to machine) metal that is used extensively in the racing and aeronautical industry (Audi Sport sells an Inconel exhaust manifold for $10,000). Inconel has excellent heat retention characteristics that work to enhance turbo response by keeping exhaust velocities high. We guarantee that this manifold will never crack. Furthermore, the production manifold is cast using a lost-wax process versus a traditional sand-casting process. This process is more expensive but gives a much higher quality part with better tolerances, no parting lines, and a smoother surface finish (the internal surfaces feel like they have been Extrude Honed).

The exhaust manifold is mated to a Garrett turbocharger that replaces the stock Triple K K03 turbocharger. We chose to use a Garrett turbocharger in lieu of a Triple K unit for several reasons. First of all, the new Garrett GT-Series is a more efficient design than the old Triple K K-24 turbocharger used by one of our competitors (the K-24s design dates back to the mid 70s). The Garrett turbocharger we have selected is a 1990s design. Also, Garrett turbochargers are available in a wider variety of configurations than the Triple K line, which allowed us to find a more exact match. The stock injectors are maxed out at power levels much over 220HP and consequently the fuel injectors have been replaced by larger units. Dialing in the injectors required many hours on the chassis dynamometer to achieve the proper fuel mixture throughout the entire rpm range.

2.7T Stage III Turbo Kit
Power, Drivability, Reliability: these three words sum up our Audi 2.7T K04 Stage III kit. APRs unique approach to product development brings together a product with the level of refinement that this car deserves.

APR has a history of developing high-quality turbocharger upgrade kits. Our 2.7T Stage III upgrade system continues this tradition. This product uses RS4 components, APR-designed components, and of course, APR-engineered engine management software calibrations.

This ultimate turbo system upgrade is now available for the 2.7T cars. This kit is capable of 447 horsepower and 467 foot-pounds of torque at the flywheel on 93 octane gas, while retaining stock-like drivability. The highlights of the kit include the following:

• RS4 KO4 Turbochargers
• RS4 MAF and Airbox
• RS4 MAF to Turbo Inlet Plumbing and Y-Pipe
• RS4 High Flow Fuel Injectors and Fuel Pump
