Pretty sure they sell rebuilt waterboxer type motors, but no Subaru or other conversions. They have a little write up on their motors on gowesty.com . Lots of other folks out their using the Subaru motors though. I am planning on doing the conversion to my '87 as well.
Correct. Lucas does not endorse the Subaru swap. He does provide several ported Wasserboxer engine options which produce more horsepower.
