The 2.5 RS was the highest performing Impreza you could buy from U.S dealers. These cars came with larger, more powerful 2.5L engines (compared to 2.2L on the base cars) as well as a viscous limited-slip rear differential with a 4:11 final drive. Paired with relatively close transmission gear ratios, a wide powerband, and a factory short shifter, these cars are nothing short of engaging to drive
1999+ are the model years to focus on, as these cars feature the much more durable “Phase II” SOHC engines (compared to the DOHC engines in pre-1999 cars). The DOHC engines were notorious for blowing head gaskets and breaking lower piston ring lands (the DOHC pistons are literally skirtless and were prone to piston slap). Phase II engines feature full-length slipper skirts and updated cylinder heads/hardware/gaskets. While Phase II engines weren’t flawless, they were more dependable, make slightly more torque and provide better fuel economy than the DOHC engines
These 2.5L engines have a high bore-to-stroke ratio of 1.26 (99.5mm bore, 79mm stroke). A ratio of 1.1-1.3 is typically reserved for race engines, and is rarely found in a street engine. A small stroke (relative to bore) keeps piston speeds low, which in turn reduces friction in the engine. This is desirable for high RPM engines
The wheel wells on these cars are so wide that Subaru was forced to build the 7″ wide wheels with a high 53mm offset to fill the wheel well opening
Key Model Year Changes:
First year of Blue Ridge Pearl, which was only offered in 2000 and 2001
First year of the rear limited slip differential (the tried and true Hitachi R160, found in cars like the Datsun 510)
New 6 spoke wheels
First year of the MAP engine tuning (manifold air pressure), replacing the old MAF (Mass Air Flow) setup
First year of child-restraint mounts (makes it easier to install a racing harness)
The 4 door sedan 2.5 RS becomes available this year, sold alongside the coupe
The following year (2001 – final year of production) only saw minor interior changes, such as standard carbon fiber trim
1999-2001 models are generally grouped together as the “Phase II” cars with updated SOHC cylinder heads. These engines are more durable and produce slightly more torque than the DOHC engines found in problematic pre-1999 cars
