I've seen that one too. Instant classic!

I would guess you'll need around 15 HP to maintain 60 mph.
No need to guess. Check the link to the calculator tool in my post above. If you know the Rabbit's specs, you can plug in the figures. The default values in the form are for my car, stock (which had similar Cd, A & weight characteristics of the Rabbit, though you'd have to adjust the engine efficiency value, obviously, if you want it to spit out MPG estimates). Figure some moderate aero mods are going to knock a few points off Cd, and your power requirements drop even more.

But as you stated, who cares, since the gearing is as low as you could get it anyway.
Custom 5th gear, ftw! After $4k for an engine swap... why not?

(Oh, it's SO easy to armchair engineer someone else's project!)
