Do you know if there is a fan club for the 1980 Plymouth Horizons? Some of them look amazing restored, and turbocharged! Want to buy one . TPDM
Your best option would be Turbododge.com or Turbo-Mopar.com. These are both forums devoted to the turbocharged Chrysler vehicles of the 1980s and early 1990s. There are plenty of L-bodies (the Horizon platform name) for sale on there. Also try the L-body cars Facebook page.
