After All, We Are The Current Record Holders For The Most Powerful 2.1 In The UK

Rocko 650 WR1

   The award-winning Subaru Impreza WR1 is a limited edition of 1000 Japanese MY04 WRX STI's with DCCD were exported to celebrate victory in the 2003 WRC drivers' championship. 500 were sold in Europe, Australia and South Africa as the Petter Solberg edition; the other 500 were further modified by Prodrive and sold in the UK as the WR1. They had 316 bhp (236 kW) and 309.8 ft·lbf (420.0 N·m), an incredible 0-60 mph time of only 4.25 seconds and a top speed of 155 mph (249 km/h) (electronically limited). They were equipped with Prodrive WRX STI springs, Pirelli PZero Nero tires, mesh grilles, special Ice Blue matalic paint and Prodrive PFF7 Pewter wheels. The new ECU and exhaust were not EU-homologated, so they were fitted after registering the car... We decided to change this WR1 a little and raise the bar!

  The success being enjoyed by our 750bhp 2.1 with both critics and public alike crosses all borders having to agree, it has been proven in a host of different events from the UK and into Europe. In Malta, our 2.3 version was run at 748bhp up the drag strip and on special fuel of course.

 Every Subaru performance engine from Advanced Automotive is the result of an uncompromising design approach that integrates innovation and many years of dedicated experience which we apply to every build, we are continuously improving and raising the standards and set no limits.

The Custom R&D 2.1 Engine In The Subaru Impreza
Our Record Breaking 2.1 As Seen In A 2016 Banzai Magazine Feature

Rocko 650 WR1

The Subaru Impreza (second generation) is a compact car manufactured between 2000 and 2007 by Subaru in Ota, Gunma, Japan.
As with its first generation predecessor, Subaru split the range into four-door sedan (GD series) and five-door hatchback (GG series) body variants; the firm did not carry forward the previous coupe style. Mainstream versions received naturally aspirated 1.5-, 1.6-, 2.0-, or 2.5-litre flat-four engines, with the performance oriented "WRX" and "WRX STI" models uprated to turbocharged versions of the two latter options. Like most Subaru models of similar vintage, all-wheel drive tended to be offered as standard in export markets, with front-wheel drive also available in Japan.
Introduced as the "New Age" Impreza, the polarizing headlamp styling divided critics who were quick to designate the model as the "bug eye" Impreza. A subsequent facelift in 2002 toned down this frontal styling, but a second facelift in 2005—characterized by an aviation-inspired three-part mesh grille—also attracted controversy... We decided to change this Bug a little and raise the bar once again!
