Subaru Forester (2nd Gen) Buyer's Guide

The Turbo SUV Pioneer

The 2nd-gen Forester (SG, 2003-2008) was the first Forester to offer a turbo engine, creating a blueprint that Subaru would follow for years. The XT models with the legendary EJ255 turbo are genuine collector cars today.

Powertrain: The 2.5L EJ251/EJ253 naturally aspirated (165 hp, 2003-2005; 173 hp, 2006-2008) with 5-speed manual or 4-speed automatic is the volume engine. The 2.5L EJ255 turbo (210 hp, 2004-2005 XT; 224 hp, 2006-2008 XT) with 5-speed manual or 4-speed automatic is the enthusiast gem — the same engine as the WRX. The XT is one of the quickest SUVs of its era (0-60 in 5.5 seconds).

What to look for: The XT turbo is the collectible pick but check for turbo health, head gaskets, and oil starvation. The naturally aspirated EJ251/EJ253 has head gasket issues. Check for rear strut tower rust (2003-2005). The 2006+ models have a better interior.

Generation

About the 2nd Gen

The 2003-2008 Subaru Forester, the second generation, grew in size and refinement over its predecessor while retaining the brand's hallmark symmetrical all-wheel drive. This generation moved from a compact wagon silhouette to a more SUV-like stance, though it remained car-based and offered excellent ground clearance. Engine choices included a naturally aspirated 2.5-liter four-cylinder producing around 165 horsepower, plus a turbocharged 2.5-liter (available from 2004 in the XT trim) that delivered roughly 210-230 horsepower depending on the year. Both engines paired with either a five-speed manual or a four-speed automatic transmission; all models were full-time AWD. Trim levels ranged from the base L and X to the upscale XS and LL Bean, with the sporty XT reserved for the turbo variant.

As a used buy, this Forester generation suits buyers who need dependable all-weather capability, solid cargo space, and a comfortable ride in a compact SUV package. The naturally aspirated engines are known for longevity but require attention to head gasket maintenance, while the turbo models offer notable performance at the cost of higher maintenance demands. The 2003-2008 Subaru Forester is generally praised for its safety ratings, visibility, and resale value, though interior materials and noise isolation trail modern competitors. It remains a practical choice for outdoor enthusiasts and those seeking a rugged, reliable crossover without the bulk of a truck-based SUV.

FAQ

Frequently asked questions

Is the 2nd-gen Forester a classic now?

The XT Turbo is becoming a legitimate collector car — clean examples are $8,000-12,000 and rising. The NA models are budget-friendly but need head gasket attention.

Should I buy an XT or an NA Forester?

The XT is the enthusiast choice — 224 hp, EJ255 turbo, and genuinely quick. The NA is the budget choice. Both need head gasket attention and rust inspection. The XT is worth the premium.
