Assuming it's this one: http://www.zenithair.com/misc/turbine-power.html It's probably fun, but performance is probably decent while not extravagant. <150 lb install weight is good, but 90 HP is so-so, and prop RPM of a bit over 3,000. Really it's not as good of an option as an O-200/235/300. You have higher RPM and less power. The 50 lb weight savings is worth something, though.
