4 doors you say??!! How sad. Any idea if the IC stuff was pirated off of another model or was it GTD specific?
GTD's after '89 came with a water-cooled K14 if I'm not mistaken.. The IC setup is also GTD-specific. They also came with the SB-engine, 80 HP and 155 NM.
Like I said, it varies from market to market.
and then the real GTD MK1 1.6td engine code CY and no IC
