Subaru has launched a new series of Prodrive Performance Packs (PPP) for the 2006 model year Impreza 2.5 WRX, WRX STI, spec.D, and the new Forester 2.5 XT.

The packs feature reprogrammed ECUs, a high-flow catalytic converter, a sports exhaust silencer and, in the case of the Impreza WRX STI pack, a new high-flow fuel pump.

The result is an improvement in low- and mid-range torque – by 74 lb/ft in the Impreza WRX, for example – while top-end power also receives a boost – by 39PS for the WRX STI, which now produces 320PS in total.

The packs are available from any Subaru dealer, priced at £1,700 including VAT and fitting.  The manufacturer’s warranty is preserved in all cases.

Impreza 2.5 WRX STI With Prodrive Performance Pack

The latest Impreza 2.5 WRX STI with PPP sees peak power jump to 320 PS (316 bhp) at 6,000 rpm instead of 5,600 rpm, with peak torque of 332 lb ft at 3,700 rpm instead of 289 lb ft at 4,000 rpm. This results in an improvement in the 0-60 mph time from 5.0 to 4.8 seconds, with 0-100 mph in 12.2 down from 12.5 seconds.

The 30-50 mph time in 4th gear is also reduced from 4.8 to 4.3 seconds, with the 50-70 mph time in 5th gear comes down to 4.3 instead of 5.1 seconds. The 80-100 mph time is now 6.3 instead of 7.6 seconds.

Impreza 2.5 WRX With Prodrive Performance Pack

The new Impreza 2.5 WRX with PPP produces 270 PS (266 bhp) at 5,700 rpm and 310 lb ft of torque at only 3,000 rpm – an increase of 74 lb ft, and at 600 rpm lower.

The result is a 0-60 mph time reduced from 5.9 to 5.3 seconds and 0-100mph of 13.9 instead of 14.4 seconds. 30-50 mph in 4th gear comes down from 5.0 to 4.0 seconds with 30-50 mph in 5th gear taken care of in 4.7 instead of 6.6 seconds.

The 2006 model year Forester 2.5 XT manual with PPP sees a power boost to 260 PS (256 bhp) at 5,600 rpm with 300 lb ft at 3,000 rpm, an increase of 64 lb ft and at 600 rpm lower in the rev range.

The Forester 2.5 XT PPP now reaches 60 mph in 5.3 instead of 5.9 seconds and 100 mph in 13.9 as opposed to 16.0 seconds. The 30-50 mph time in 4th gear is now 4.2 instead of 5.5 seconds with 50-70 mph coming up in 5.0 instead of 7.3 seconds.
