he 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. We 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. Tuning is by AVO Turboworld via EcuTek reflash tools, and we will provide an AVO Stage 1 base map free of charge 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. 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 250 to 270whp on 92 octane pump gas, dependent entirely upon the quality of the pump gas. 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. We've 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 testing!
AVO18/49 Turbocharger with a 7psi actuator - compressor wheel size 49.2/56 | exhaust wheel size 50.5/68
This specially designed AVO18/49 turbocharger comes with a 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 276hp on 92 octane.
Mechanical Oil Pump Specifications:
We are 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.
A blow-off valve is strongly recommended to be fitted to ensure a stable idle. We have 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.
Stage 2 Kit Hardware:
The AVO Stage 2 Kit utilizes all of the hardware of the Base Stage 1 kit, and adds on the following components:
- AVO 7psi Actuator
- 3-bar MAP Sensor
- AVO Street Breather Tank system with Turbo PCV Valve Upgrade
- AVO Ceramic Coated Cross-over Pipe
- AVO Stainless Steel Front Pipe with 5" Metal Cat
- Stage 2 Base Map [EcuTEK]
