Young Version — August 1999

Aristo with T67 turbo: more tuning shops have launched Aristo turbo builds using large T67 turbines, so the label alone no longer surprises anyone—the quality of the tuning matters. Trust’s Aristo Turbo uses a prototype turbo kit and relatively mild upgrades to cooling and brakes, yet its approach has a clear character. It selects a fairly large 67.25G turbine for the Aristo and runs it at a low boost pressure of 0.5. Why? Trust says this avoids the sudden torque surge typical of turbos. A small turbine at high boost can make response overly sharp; a larger turbine at low boost delivers power more smoothly. .

The power delivery is smooth, but it is still fast. What is it like to drive? On a full-throttle run there is no dramatic point where power suddenly explodes. Instead, it produces useful torque from low rpm and accelerates as expected whenever you press the pedal. You might be disappointed if you expect a sudden “kick,” but it is more than fast enough. Maximum power is said to exceed 288 . Since the turbo has capacity, further tuning to raise boost could produce considerable power. But this is a bolt-on setup that leaves the engine itself untouched. The counterintuitive idea of using a large turbo at low boost gives the engine mild characteristics, reduces tuning costs, and may also help transmission durability. The A-con brake system provides the stopping power needed for the car’s speed. .
