"There are few (if any) naturally-aspirated vehicles on the road that wouldn’t benefit from forced induction for increased output.

This is particularly true of vehicles with plenty of potential right from the factory. With neutral and predictable handling, a low center of gravity that rivals all but the most exotic of road cars, a curb weight around 2,700 pounds and a sticker price in the $25,000 range, the Scion FR-S and Subaru BRZ seemed to have the makings for an incredibly fun and nimble sport-compact coupe the market has desperately desired. However, the 200 horsepower FA20 Boxer engine that adds motility to these machines leaves a little bit to be desired in the power delivery department. It’s certainly not bad, but it could always be better."

"It doesn’t take a genius to see that the ZN6/ZC6 chassis would be a popular platform given its desirable traits. So it comes as no surprise that a myriad of power adding solutions from nitrous oxide injection kits to supercharger and turbocharger systems were developed as soon as tuners and manufacturers could get their hands on test vehicles. While many of the supercharger kits made early debuts at the SEMA Show in 2012 (along with over 60 FR-S/BRZ that flooded the convention hall floors), some of the turbo kit companies elected to hold back the unveiling of their product until all of the bugs had been worked out. One of these companies was AVO Turboworld."


"Both turbocharging and supercharging have their benefits and drawbacks, which often fuels the ongoing debates between the two camps. Turbocharging offers the efficiency of generating boost by way of high enthralpy exhaust gasses rather than drawing from the crankshaft like a supercharger. Increasing boost pressure is limited only by the wastegate and or the physical limits of a given turbocharger’s size. On the flip side, some would argue that a turbo system requires more components and ancillary equipment than a supercharger, which could in turn add complexity to a power adding system."


"AVO Turboworld developed its base turbo kit as a bolt-on complement to the stock FA20 engine. Utilizing the factory air intake box with an AVO panel filter and designed to mate to the stock exhaust by way of anAVO turbooutlet pipe, the minimally invasive design makes the system subtle and practically unnoticeable to the casual observer. The unequal length stainless steel exhaust manifold feeds a low mount AVO18/49 turbocharger positioned at the same height as the exhaust manifold. This helps to maintain the low center of gravity that had been engineered into the vehicle. In addition, all of the piping and the bar-and-plate front mount intercooler come powder coated black to further lend to its stealthy appearance."


"Since this kit positions the turbocharger at roughly the same height as the oil pan, it’s not possible to rely on gravity to draw oil from the turbocharger’s center cartridge back to the engine. Therefore, AVO Turboworld includes an oil reservoir and a mechanical scavenge pump that mounts to one of the right hand camshafts. This thoughtful solution ensures that the scavenge pump’s flow rate is directly related to engine speed, drawing enough oil from the reservoir when the engine is at low RPM and idle as well as at high RPM."


"AVO Turboworld engineered its stage one turbo kit for those seeking drivability and daily reliability. The responsive AVO18/49 turbocharger features a 5-7 psi internal wastegate actuator in anticipation of modest boost levels, given the FA20’s high 12.5:1 compression ratio. The relatively lower boost levels do not require the use of an overly built fuel delivery system, especially since the FA20 benefits from a hybrid direct injection/port injection system. Thus the factory injectors remain unchanged. Nonetheless, as a precaution, the AVO Turboworld test vehicle had been upgraded with an AVO Turboworld highflow fuel pump."


"AVO Turboworld performed extensive testing and evaluation of the kit along with refinement to the tune in a variety of conditions, including extreme temperatures and at various elevations to ensure that the kit would function under any conditions. Once installed, the base kit along with AVO Turboworld’s included Stage 1 ECU program (implemented by way of EcuTek’s reflash software and cable that must be purchased separately) are projected to make anywhere from 230-250 horsepower, depending on the quality of the pump gas, geographical location and the conditions that the vehicle is tested."


"Everything usually sounds good on paper, but the real proof is always on the dyno. AVO Turboworld brought its test vehicle down to Fountain Valley, CA to put its product to the test. On DSPORT’s Dynojet 424xLC2 dynamometer, the FR-S (which was equipped with AVO Turboworld’s 3-inch stainless steel exhaust) spun the rollers to a peak output of 241.24 horsepower and 190.17 lb-ft torque. Although peak boost pressure was recorded at 8.04 psi, the average boost pressure from 3,000 RPM to 7,250 RPM was 5.89 psi. For a higher output comparison, the boost was increased by way of an optional AVO Turboworld boost controller. With peak boost recorded at 10.39 psi, the FR-S raised its peak numbers to 269.37 whp and 223.77 lb-ft. The average boost pressure from 3,000 RPM through redline was a modest 8.72 psi."


"It seems as if AVO Turboworld really spent a good amount of time developing and testing this turbo kit for the FR-S/BRZ. The inconspicuous low-mount turbocharger, black piping and stock air box do a great job to maintain a low center of gravity while avoiding detection by the casual observer or the uneducated eye. Whether or not you like the rumble of an unequal length manifold, its design lends to quicker boost response at the expense of some top-end power. Compared to our test FR-S that currently features a positive displacement supercharger, the AVO Turboworld kit delivers solid power production and supports the output thresholds of the factory engine. This turbo kit might be the only one for the FR-S/BRZ that flies under the radar of both your wife and the police."
