Tunehouse enters the World Time Attack Challenge with a Subaru WRX STI

Tunehouse entry into this year’s World Time Attack Challenge is Fytos George’s MY08 Subaru WRX STI. Competing in the Clubsprint class, the car features a 2.6L stroker engine with hand-ported heads with THR camshafts and inlet manifold, a THR tuned length header and a THR spec turbocharger.

Tein Monoflex coilovers were used in the suspension department with custom spring rates to suit the road orientated tyres used under the Clubsprint class rules. The crew spent considerable time getting the corner weights right in order to make the car handle like a race car. The brakes also copped an upgrade with a set of AP Racing brakes on both ends including six-pot front calipers on the front. Jim personally oversaw the whole project and tuned the car himself.

“I’m confident the car will be competitive in its class,” said Jim “It’s a great street car but it can mix it with the race cars on the track as well.”

We can’t wait to see it in action!
