Prototype high flow turbo produces 400ps!
Street tune is a must see for GR Yaris owners
HKS is currently forging on with tuning the GR Yaris, notching such achievements as being the first tuning shop to get one round Tsukuba Circuit in under a minute. Today we introduce a demo car that gives some pointers as to HKS’s approach to tuning the Yaris for the street.
First up under the microscope are the aero parts above – test products aimed at achieving the best of both worlds between form and function. The canards, middle spoiler, and the rear under spoiler; all are the products of an ambition to produce as much downforce as humanly possible within the boundaries of legal safety standards. And it’s impossible to miss the carbon fiber bristling from every nook of the car, giving it a truly high-grade feel.
Producing the power, a high flow turbine combines the standard IHI center cartridge with large diameter billet blades. Although this is a pure bolt-on modification, it raises power to an incredible 400ps. The intercooler and oil cooler too are high capacity prototype parts, and promise to provide trouble free cooling for street use.
Increasing air-intake’s efficiency is a heat-shielded racing suction kit, which plays problem-free with the stock ECU. The plug-and-play “Power Editor” (45,000 yen) is also a simple bolt-on and accommodates more boost, pushing power output up by 20ps.
The Super Turbo Muffler (198,000 yen) has a straight-through layout, capable of handling up to 500ps whilst remaining road legal. The sound tuning its “Silent Chamber” offers elevates the sound of the 3-cylinder engine into something far more sensual.
The suspension is a test version of HKS’s headline-grabbing lead product for 2021 “Hipermax S”, and both ends of the car equip Endless’s Big Caliper Kit. Showing off the moderately lowered stance are Advan Racing’s brand new TC-4 rims (9.5J +45 x 18″).
This is a brilliant balance of everything the street scene demands from a car – performance, ease of use and styling. What’s more, we understand the parts you see here will be hitting the market in the near future. GR Yaris owners, stay tuned!
