AVO Turbocharger Kit for the Subaru BRZ, Scion FR-S, and Toyota GT86!
The AVO Turbocharger kit is designed to work with both RHD and LHD models in all
countries, and extensive testing has been done on both the Japanese Subaru BRZ
and the US Market Scion FR-S. The Japanese BRZ has been track tested from day 1,
and the US Market FR-S has spent 16 months and 25,000 miles testing and tuning
in varying conditions, from 6000 feet and 0 degree temperatures, to sea level
and below in the desert! This was done to ensure the AVO kit will hold up as a
daily driver where ever you go, whatever the conditions. All testing in the
American market was conducted on 91 and 92 octane pump gas to ensure this is
going to handle daily driving as well as the track.
The turbocharger kit is designed from top to bottom specifically to the FR-S and
BRZ, and consists of the all the parts necessary to bolt the kit up to the car.
The AVO Kit utilizes an AVO18/49 turbocharger that mounts up under the front of
the engine via our stainless steel unequal exhaust manifold, and then it bolts
up to the stock exhaust with our polished stainless steel turbo outlet (also
referred to as a downpipe). Cooling the pressurized air is an aluminum bar and
plate front mount intercooler which uses black piping throughout, mechanical oil
scavenging pump, oil reservoir tank, and all necessary water and oil hoses and
fittings. Tuning is by AVO Turboworld via EcuTek reflash tools, and they can
provide an AVO Stage 1 base mapfor use with the Stage 1 kit.
This turbokit has been designed to bolt up to the stock air intake box and to
the stock exhaust system. AVO has spent a lot of time ensuring it will work with
the standard fueling system for a complete bolt on and go setup. The beauty of
the system is that it looks very stock from above! The FMIC has been
specifically designed to fit with the standard bumper without trimming as well,
and on FR-S models would be be difficult to see unless you are looking for it.
So what can you expect from this kit?
From testing, you will see anywhere from 250 to 320whp on pump gas, dependent
upon the quality of the gas it is tuned for. This is due entirely to the fact
that the stock motor is 12.5:1 compression, incredibly high for a n/a motor.
This makes gas quality even more important than ever! If it wasn't for the fact
that this FA20 motor is a completely different and modern design with an
incredibly well made combustion chamber, we wouldn't even attempt to turbocharge
these cars. But while many people associate it with the old EJ20 series motors
from Subaru, there is absolutely no comparison besides the fact they are both
boxer 4's made by Subaru. The entire design of the engine is different,
especially the combustion chamber, which has been improved tremendously from
anything previously made by Subaru.
Not only is the engine a major step up, the ECU on this car is also a great
design, reacting incredibly fast to knock and adjusting parameters to
compensate. This helps increase the reliability of the turbocharged motor. As is
well known by now, this is also a direct injection motor, helping both power and
gas mileage. AVO has seen mpg figures as good as stock on the freeway, probably
better than stock as we were not exactly sitting on cruise control during our
As you can see from the dyno chart you can make up to 400whp on the base kit
with the right supporting modifications. That is over 470hp at the crank, well
into supercar territory!
AVO18/49 Turbocharger with 6 or 8psi actuator - compressor wheel size 49.2/56 |
exhaust wheel size 50.5/68
This specially designed AVO18/49 turbocharger comes with a 5-7 psi actuator for
precise boost control at lower psi levels, ensuring engine longevity.
Mechanical Oil Pump Specifications:
AVO is unique in utilizing a mechanical oil pump that we locate at the back of
the engine, which runs off the back of the RH camshaft. There is also a oil
reservoir tank right off the turbocharger itself. This is the most reliable way
to pull oil through the turbo to the engine, as it keeps the flow rate tied to
the rpm speed of the motor, ensuring that it's properly scavenged at low rpms
and idling, and has enough at high rpms.
Front Mount Intercooler Specifications:
Bar & Plate Aluminum Intercooler with cast endtanks. Length = 19" Height =
8" Width = 3"
The intercooler kit utilizes black wire-reinforced silicone piping and two black
powdercoated steel piping. The intake piping has ports to mount up a variety of
blow-off valves, even OEM ones for a full stealth look.
Additional standard equipment in this kit: Blow-off Valve, Breather tank
system, and 3-bar MAP sensor
