It’s difficult to beat an Impreza when it comes to rallying, but when it comes to a tarmac track, they can fall victim to dreaded understeer. And to be completely honest, they’re not overly good track cars straight from the factory. There are however, things you can do to a Subaru Impreza to make it a lot faster. And no, it’s not to sell it and buy an Evo.

The owner of the car shown in the video above is certainly on the right track (pun not intended). He’s fitted his 2003 Impreza STi with an engine built by ABperformance featuring a Precision 60/62 turbo, 2.1 stroker kit, and a Process West intake manifold. Hanging off the rear is a Tomei Expreme Ti Titanium exhaust – hence its incredible sound.

But the part that gets the medal for me is the KAPS 6-speed sequential transmission. It still has a physical clutch so it’s not entirely automatic, but the dog box allows the gears to be shifted much faster than a standard manual ‘box.

I think it’s safe to say I want one in my car. I just wish they came standard in more road cars!

Before you leave to indulge in your own dog box fantasies, take a look at the same Impreza pulling all 800 of its horses on the dyno. It’s a real machine and it’s definitely making me want to try the Scooby life. And take a look at the $250,000 Impreza while you’re at it.
