I purchased a ford focus titanium 2.0 L inline 4 in hopes of making a sleeper vehicle. I was wondering about fitment of parts made for the ST model. I k ow that the engine is the same other than the ecoboost turbo charger. When it comes to internals or exhaust would i be able to purchase st parts and would they fit onto the titanium without heavy modification. If not does anyone know where I can order custom parts.
