Subaru Justy 3-cyl = Steamer?

Hi Live Steamers,
Please assist me in a steam engine application. I've been offered a used, mid-90's Subaru Justy engine. It's a 3-cyl inline, w/FWD constant velocity transmission attached. I understand 3-cyl inlines are good for steam conversions due to the fact that 1 piston will always be in a power stroke on a 120-degree crankshaft, this being a single-acting configuration.
Obviously, the engine must be modified to make the cam run at the same speed as the crank so it will be in 2 stroke mode. Positive rotational direction control will be achieved by allowing the starter to run in both directions as required (as well as by the CVT transmission, if I keep it).
My next question is: should I use the OEM intake for the steam inlet or shoot the steam into the spark plug hole and convert the intake valves into 2nd exhaust valves, via cam lobe mods, for higher cylinder clearing efficiency? This would mean a new steam inlet control system. I envision using the distributor shaft to manage the valving for it.
Last one: rust and how to control it.
This engine will be available to other experimenters if I pass on the deal. The location is northern Colorado near Greeley. I will pass on inquiries to the owner. Thank you for your assistance! 8^)
