Problem overview

Some Subaru WRX STI owners report experiencing significant costs associated with engine replacement, typically around $6,500, which includes both the engine and labor charges. Others consider rebuilding the engine as a more affordable option, usually costing around $5,000, while some opt for a used engine installation to save money, especially if they plan to sell the car afterward. When contemplating whether to repair the blown engine or sell the vehicle as is, owners must evaluate factors such as the car's current market value, repair costs, and potential resale value. Additionally, some owners have noted that the market value of a WRX STI with a blown engine can vary, attracting interest from enthusiasts looking for project cars or parts. Legal considerations are also a concern, as engine failures in some Subaru WRX/STI models have been linked to defects, leading to lawsuits that may benefit affected owners. Seeking advice from Subaru specialists or mechanics is often recommended to gain insights into the best course of action, including repair options, costs, and resale potential.
