Brian Crower Econo Series Connecting Rods Subaru WRX STI EJ205 EJ257
The Subaru Impreza WRX, or "Impreza Rex" is a turbocharged version of the Subaru Impreza, a small all-wheel drive sedan. The WRX has become a popular choice for automobile enthusiasts wherever it is sold for its high performance, great handling, and relatively affordable price. Originally introduced in 1992 in Japan, then shortly afterwards in Australia and Europe, the WRX had a turbocharged flat-4 2.0 L engine producing 211-220 PS (155-162 kW), according to the ECE or JIS standards. From 1997, the restyled WRX offered 227 PS (167 kW). Compared to the base Impreza, the WRX had wider low-profile tires, larger brakes (further improved in later versions with the fitting of four-piston calipers and larger discs), and firmer, higher quality suspension components. The United States model Impreza WRX features the EJ205 (non AVCS), although the EJ207 (AVCS) found internationally can be converted to non-AVCS format with a little work.
A series of low-volume versions with even greater power and grip were built by Subaru's in-house modifier, Subaru Tecnica International (STi). STi versions of the Impreza, which produced 280 PS (206 kW) from new, are often raced, largely unmodified, in the Group N class in various rally championships to great success. Introduced in 1994, the STi has proven to be a very popular high-performance machine in the Japanese domestic market. Introduced to the United States in 2004, the US model STi features the larger displacement 2.5L (EJ257) that features AVCS.
Made from premium, 4340 steel billet material, BC connecting rods are available in two distinct styles depending on horsepower, budget and engine application. The BC Econo Series is intended for moderate boost applications and all motor race applications where peak horsepower is not going to exceed 650 at the flywheel. The BC Pro Series rods are designed for high horsepower, high boost and extreme rpm applications where nothing but the best rod will do. Features include ARP 220,000 p.s.i. rod bolts for ultimate fastening capabilities as well as aluminum-bronze bushings to insure long, reliable service, no matter what the boost, nitrous or rpm.
Econo rods are intended for under 650 flywheel horsepower. If over that, use Pro Series.
