APR Tuned Stage III Power Upgrade without IC or FP Volkswagen Golf GTI 2.0T FSI 06-08

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 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, 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. 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
- APR Honeywell/Garrett Ballistic Series Ball-Bearing Turbocharger
- Larger APR designed Mass Airflow Sensor Housing
- APR Custom Cast Silicone Intake Hoses
- APR FSI Fuel Injectors
- All Associate Plumbing and Hardware

The power increase with the APR Stage III kit for the 2.0T is substantial. It is highly recommended that brake and suspension upgrades are done to safely use the potential of this upgrade. It is also recommended that the stock engine internals be upgraded for power levels above 93 octane, as APR is not responsible for this type of damage to the engine.

Components

Stage III Intake: 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.

MAF Housing: 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.

Turbo Compressor Inlet Hose: 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 Diverter Valve Adaptor: APR includes a billet CNC adaptor that allows the stock diverter valve to be reused with the APR compressor inlet hose.

Honeywell/Garrett Turbocharger: 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. APR engineering-house distributor status with Garrett turbochargers means that they receive assistance from the manufacturer on technical issues and work with Garrett engineers on specifying the optimal turbocharger for each application.

APR Oil/Coolant Lines: 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.

Compressor Outlet Hose: 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.

Compressor Outlet Pipe: 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.

APR FSI Fuel Injectors: 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.

Exhaust Manifold: 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.

Cast Exhaust Downturn: 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.

APR 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.

Does NOT include Intercooler or Fuel Pump.
