The Concept
It began with a phone call from Volkswagen of America (VoA) requesting information about available engine performance packages for an upcoming concept car they were planning, the R-GTI. APR reputation of reliability and drivability with our turbo upgrade packages for the 1.8T qualifies APR as the only logical manufacturer of a turbo solution for the 2.0T. After several conversations about power requirements and drivability, the Stage III for the 2.0T was visualized.

APR had always planned on developing a turbo upgrade for the 2.0T, but the R-GTI was an excellent opportunity to put the project into overdrive. APR's engineers began designing and testing exhaust manifolds, intercoolers, fuel pumps, injectors, induction and boost pressure piping, MAF housings, oil and coolant lines and selecting turbochargers to meet the rapidly approaching deadline. Cutting edge parts in a short period of time made APR rely heavily on some of our in-house development tools.

APR engineers drew parts for the 2.0T Stage III kit using Pro-Engineer Wildfire CAD software. Prototypes of the new concepts were 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, a cast metal prototype can be made if needed. During the midst of all of this the project became even more interesting as a competition was announced.

The VoA GTI Tuner Challenge was formed and APR was invited. The VoA R-GTI concept car was to be set as the standard of which all other vehicles were compared and along with APR, the top Volkswagen and VW tuners in North America were invited to pit their skills and talents against each other and Volkswagen of America.

Late nights and last minute deadlines resulted in members of APR's engineering team flying out to the Volkswagen of America's California Design Studio for the engine package installation. Arriving and leaving the same day, APR provided a turn key solution that brought the R-GTI to over 400hp.

2.0T FSI Stage III Components

This page focuses on the items that are included with the 2.0T FSI Transverse Stage III. Because this kit is so extensive, it would be impossible to highlight all of the items that are included with it. The APR 2.0T Stage III kit includes ALL components needed (except a catback exhaust, oil, and coolant) to take a car to 382hp/332lb-ft.

The APR kit starts with a Carbonio derived carbon fiber intake which takes air in from the fenderwell of the car. This helps the car by allowing the engine to continuously have a fresh supply of cold intake air.

Since the stock FSI MAF is integrated into the factory airbox, APR developed a new housing that is sized according to engine displacement and maximum power output. The new cast housing allows the proper metering of the additional airflow and to minimize pressure losses. The cast aluminum housing is CNC machined to exacting tolerances and powder-coated to inhibit corrosion. A honeycomb style flow straightener is also added to prevent the MAF from seeing erroneous signals.

APR uses a reinforced silicone hose to route the inlet air from the MAF housing into the compressor inlet of the turbocharger. This hose also has provisions for other connections, such as the stock crankcase vent hoses and the APR diverter valve adaptor.

APR includes a billet CNC adaptor that allows the stock diverter valve to be reused with the APR compressor inlet hose.

Representing the latest in turbocharger technology, a Garrett GT2871R Ballistic series turbocharger is the only choice for this premium turbocharger system. APR is unique in that we deal directly with Garrett turbochargers rather than buying turbochargers through turbocharger supply houses. Our engineering-house distributor status with Garrett turbochargers means that we receive assistance from the manufacturer on technical issues and work with Garrett engineers on specifying the optimal turbocharger for each application.

All APR oil and coolant feed and drain lines for the turbocharger are made to higher than OEM standards. As an example, the oil drain line (pictured) includes a braided stainless line with pressure crimped fittings, billet adaptors for the turbo and oil pan, new OEM gaskets, and stainless hardware.

This silicone hose directs air from the compressor outlet of the turbocharger to the cast APR compressor outlet pipe. The APR diverter valve adaptor also connects to this hose, as well a boost signal line for the N75 boost control valve.

Also known by some as a "pancake pipe", this cast piece bolts to the passenger side of the engine and transfers pressurized air from the turbocharger compressor outlet hose to the intercooler inlet hose.

Keeping low intake charge temparatures is essential to maintaining powerful and safe operation of the APR Stage III kit. The APR FSI Intercooler is a perfect OEM intercooler replacement with an intercooler core size almost three times the size of the original unit. This intercooler is so efficent, that it performs incredibly even in the constant acceleration seen on a road course. For more information about the intercooler, see the APR FSI Intercooler page.

The stock high pressure pump is incapable of pumping a high enough volume of fuel to support the FSI engine with even moderate mods, much less a large turbo kit. To rectify this, APR has developed a higher flowing fuel pump that eliminates this being a problem. For more information about this pump, see the FSI Fuel Pump page.

APR spent many hard hours taking FSI injectors (which already flow more than the stock ones) and then developing a process to modify them to flow even more.

The Stage III exhaust manifold is investment cast out of Inconel, a high-temperature nickel alloy. The manifold was designed in CAD and optimized using computational fluid dynamics (CFD) software. What this means to the end user is the ultimate in performance and reliability.

After the exhaust gases have left the turbocharger turbine, they flow into this stainless steel piece that directs the exhaust gases down, towards the underside of the car into the supplied exhaust downpipe.

From the cast APR exhaust downturn, the exhaust begins its travel out of the car through the three inch downpipe that is included with the Stage III 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 America's R-GTI Concept Car and APR's VoA Tuner Challenge Winning GTI!

APR began developing complete turbocharger upgrade systems in 1998 and 1999 brought the release of APR's first Audi/VW 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, APR's 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.
