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

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-24?s design dates back to the mid 70?s). The Garrett
turbocharger we have selected is a 1990?s 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. APR?s 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:
