Looking for a sub-100hp engine with long TBO time.

I know couple of my freinds who are using modified auto engines for their
home built aircrafts. Engines they used are from the following model cars:

Honda Civic 1.2 Lit
Toyota Corolla Diesel, 1.8 Lit
Daihatsu Charade Turbo Diesel, 1.0 Lit, 4 Cylinder (In fact I 'm considering
using the same engine, very compact in design and light weight)

If any one interested in gettin these engines please hit me I can arrange
that. These engines could be zero miles refurbished or could be thousands
miles on it, depending on price. All the above listed models are overseas
models and you don't find them in US market.

This is for a hypothetical ultralight design, so just looking for
suggestions here of where to look at... hopefully a 4-stroke, purchase
price doesn't matter much, certification status doesn't matter either.
Long time before overhaul matters A LOT... so, the longer the better.
Is there anything out there in the 80-hp range? How about a motorcycle
engine conversion - how long can those go before needing to be
overhauled?

Thanks!
