Performance Cams
Our goal is to
provide 'Real World'
Performance Upgrades for your 2.5RS/TS, which will allow you to
increase performance up to and over a WRX, using your normally
aspirated engine as a base.
Some upgrades require you use
premium pump gas (93 Octane) and a Piggyback ECU or
some form of Engine Management.
Also, the
power upgrades
in this section can be used on your Impreza, Legacy, Legacy Outback,
Forester and Baja non-turbo engines. Some power kits are model specific
and require fabrication for proper fitment. Each Turbo or
Supercharger kit requires you run premium fuel
and upgrade your fuel injectors for safe fuel delivery.
Please contact us to confirm your
application.

is greatly
improved. You can see gains in HP up to 19HP at redline (6500RPM). when used with supporting
upgrades and modifications.
Our 'Hottest' Performance-Race Cams are designed for naturally aspirated and turbo charged
applications. The cams are new 'Hardwelded'
cams (race quality). They provide intense mid and high range torque,
with a good idle and awesome performance. Engine Management, FPR and
increased injector size maybe required.
- Power will begin at
about 3500rpms and continue to redline (6500 RPM).
- You can see gains in HP up to 25HP, when used with supporting
upgrades and modifications.

AVO FMIC TURBO KITS
FMIC Subaru 2.5i Engine
Turbo Kits
Stage1 and Stage2

These
kits transform your 2.5i into an absolute beast with double the
horsepower from stock! AVO was the first to develop a turbocharger kit
for the 1999-2004 Impreza 2.5RS in 2001.
A FMIC allows for more flow and better cooling. The turbocharger is
specifically engineered for this FMIC application, that spools up
quickly and fantastic mid-range torque! This is due to our own cast
exhaust housing design which was created specifically for this
application. Along with the stainless steel uppipe and downpipe, the
kit contains all the necessary hoses, oil lines, water lines, and other
fittings necessary to bolt this kit up. The turbocharger is both oil
and water-cooled, just like in stock turbocharged vehicles - and just
as reliable.
What kind of power can you expect? Take a look at the graph below! Over
200whp on a dyno where stock N/A cars barely break 100whp. And it's
easy power too, generated at just 4.5-5psi. This is thanks to our
specially designed boost actuators that will run at these lower boost
levels, keeping your system from overboosting. Our experience with
these kits has shown us all the issues that need to be addressed for
running a turbo reliably, and we have taken care of them all.
Included in the AVO 2.5i Turbocharger Kit: AVO water and oil-cooled
turbocharger, AVO high-flow bar-and plate Front Mount Intercooler
(FMIC), AVO Stainless steel up-pipe, Stainless steel downpipe with a
high flow catalytic converter, Stainless braided oil lines, AVO
silicone intake pipe High quality hoses & Fittings and Full fitting
instructions
Optional Parts:
AVO Power air filter kit
This puts
it in the 265CHP/200WHP range at the engine. 100 horsepower over stock,
or basically double the stock power!
