Evo X, On the Run

OTR (On The Run) Motorsports' Evo X is a great example of how to modify and improve one of these legendary performance cars without making it any less pleasant to drive on the street.

The philosophy behind the modifications to OTR’s Evo X were to make it ready for a day of thrashing it on a race track, and capable of quicker lap times than a stocker as well, but to ensure it could still be easily driven to and from the track under its own more-than-ample power.

To achieve this they've done some engine mods, given it adjustable suspension with improved geometry, reduced the weight in a couple of areas, upgraded the brake discs and pads, fit it with wider high-performance rubber for the street and even wider semi-slicks on track days, and added a little more aerodynamic downforce as well. It all combines to produce quicker lap times without ruining its appeal as a road car.

To get the extra power from the Evo X’s 4B11T all-aluminium engine it received various upgrades including Tomei Pro cams and titanium valves, an HKS fuel rail feeding Injector Dynamics 1000cc/min injectors, an ARC intercooler, a Forced Performance Green turbo and a custom tune by Matt Lowth at ATP. The car also has a Tomei dump pipe and a 7.2kg Willall titanium cat-back exhaust. The result is a plentiful 265kW at the wheels.

The cabin also received some attention, with a Bride racing seat in a size chosen to suit the car’s main driver, and a bank of Defi BR Advance gauges in a dash-top pod.

OTR Motorsports are based in Clayton, Victoria, and their usual stomping ground for track days is Winton Raceway in the state’s north. They actually organise a number of track days for their customers to come along and see what each of their cars is really capable of, and OTR take their current projects along as well for demonstrations and just to enjoy the on-track experience themselves.

There’s a definite Evo flavour to the August edition of Fast Fours & Rotaries magazine which includes an 8-page feature on OTR’s Evo X, so to read the full details on all three of them as well as the other cars and events in this issue you need to race out and grab your copy while you still can.
