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

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
