AVO Stage 1 Turbocharger Kit - Manual(86/BRZ)

AVO's front-mounted Stage 1 turbocharger kit for the Subaru BRZ and Scion FR-S is finally here, with a North American shipping date of January 2013! The 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 22,000 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 our 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. 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.

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. 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!

As you can see from the dyno chart, 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!

Blow-off Valve - Now Included!:
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.

Breather Tank System - Now Included!:
We strongly suggest one of our 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.

Optional Equipment:
If you are interested in our Stage 2 package, but already have most of the components, such as the cross-over pipe and front pipe, we offer a Stage 1.5 upgrade that bundles together our 8psi actuator, 3-BAR Map Sensor, and a Stage 2 basemap.
