AVO's front-mounted Stage 1 turbocharger kit for the Subaru BRZ and Scion FR-S is finally here! 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. AVO utilize 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. This turbokit has been designed to bolt up to the stock air intake box and to the stock exhaust system. We have 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 our testing, you will see anywhere from 220 to 250whp on pump gas, dependent entirely upon the quality of the pump gas. We saw 230whp (276 crank hp) and 197 ft/lbs of torque at 5-6 psi on 92 octane gas literally from a nearby Chevron gas station. This was with the stock airbox with an AVO high-flow panel filter installed, and a stock secondary cat in place. All these figures were reached on the stock fueling system as well!
AVO18/49 Turbocharger with 5-7psi 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. The turbocharger is rated for 380hp of flow, so there is certainly headroom available with it from the base stage 1 kit, which is doing 300hp on 92 octane.
Mechanical Oil Pump Specifications:
AVO is unique in utilizing a mechanical oil pump thats located 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.
A blow-off valve is strongly recommended to be fitted to ensure a stable idle. AVO two different types of blow-off valves available, an OEM-style BOV and an Adjustable BOV that can be set up for vent to atmosphere.
Breather Tank System:
AVO strongly suggest one of AVOS two Breather Tank Kits to be fitted along with the turbo kit for maximum reliability against oil blow-by. There are two versions, a street and a track kit. The track kit comes with additional hardware for dealing with the extremes of circuit racing. Both kits come with all fittings and accessories necessary, including a turbo-specific high pressure PCV valve replacement that will deal with any potentionl boost leaks and protect against pressurizing the crankcase under boost. This is also a requirement for higher boost builds.
AVO turbo kit comes with a 6psi wastegate actuator as standard equipment. This works best with 92+ octane gas. For areas that only have 91 octane gas, they also offer a 5psi wastegate actuator at no extra cost. If you are interested in AVOs Stage 2 package, but already have most of the components, such as the cross-over pipe and front pipe, they also offer a Stage 1.5 upgrade that bundles together our 8psi actuator, 3-BAR Map Sensor, and a Stage 2 basemap.
