Does a Toyota Avensis 1998 GSTD have a turbo
Hi, I would imagine the letters GTSD, sum it up, ie, the TD bit means Turbo Diesel. not sure.
Hope this helps, you could look for pictures of turbos on web, basically its a fan, driven by exaust gases, that turns a fan that forces more air into engine,= more speed.so its going to be between exaust manifold and air intake, I have fitted them, but cant really explain them in simplistic terms.
