            Horsepower Range:
        
        
            Approximately 115-130 hp for naturally aspirated 2.0L and 2.2L, higher for turbo variants (e.g., 170-180 hp for 2.2 Turbo).
        
     
    
        
            Torque Range:
        
        
            Varies by engine, but generally in the 120-170 lb-ft range for naturally aspirated, higher for turbo.
        
     
    
    
        
            Injection Type:
        
        
            Bosch K-Jetronic (CIS) mechanical fuel injection for most models.
