Did you watch the X Games rally event this year? If so, you witnessed one car manufacturer flat-out dominate the competition, claiming not only the top three finishing spots, but every finishing spot altogether. Not that this came as much of a surprise; Subaru has been as much a part of rally racing as dirt and gravel since their involvement in the discipline nearly 25 years ago. The company has claimed three driver and three manufacturer championship titles in the WRC, and over 47 manufacturer wins altogether, the vast majority of which, with Imprezas that were nearly identical to showroom stock models released in the US since 2002 - all powered by ever-evolving, horizontally opposed, four-cylinder "boxer" engines. And just in case today's WRX and STI models don't satisfy your power hunger in stock form, make sure to refer to the August '06 issue's Power Pages, where we found over 30 whp and nearly as many lb-ft of torque by applying simple bolt-ons to an EJ255 in one of the first modern-day STIs to roll off the line.

Car: '91 Toyota MR2 Turbo

The early '90s Japanese performance car race was dominated so heavily by a select few big horsepower brawlers, that one of the best performing platforms of the day-the Toyota MR2-easily gets overlooked in hindsight. With the SW20 MR2's U.S. debut amidst full-scale production of the MK III Supra Turbo and Mazda's RX-7 Turbo II, and clouded by the release of the twin-turbo Z32 300ZX the same year-not to mention rumors of the upcoming Supra, RX-7, and Mitsu 3000GT VR4-the mid-engine, RWD MR2 had to struggle to keep its vents above water, despite its incorporation of one of Toyota's strongest four-cylinders ever produced; the turbocharged 3S-GTE. For our 100th issue just over a year ago, 2NR revisited this gone and almost forgotten mid-ship and was able to extract approximately 50 whp and 50 lb-ft of torque with the addition of an exhaust, boost controller, and tuned engine management system, further reinforcing why rounding up one of these little guys to build into a giant killer isn't such a bad idea.
