I own this engine in my car...

In conclusion:
1. Toyota 1.4 D4-D should be able to turn a prop at 2400-3000,
WITHOUT needing a PSRU.

But with low power: around 47kW/65HP at 2500 and near 110kg with all
accessories, water and oil.
On the optimistic side, you may have 75HP at 3000 rpm.

I thnik it's better to built a PSRU and turn the propeller at 2200rpm
for 3500 engine rpm. You add 5-10kg and get 15-20HP


3. If it's a single seat LSA, the weight penalty is not as much of an
issue.
4. Throttled back to 2400rpm, I would think the 1.4 D4-D would cruise
around all day @ (under) 2 GPH ...just a guess. g


I think 4GPH would be more real. I consider 3,5 to 4 GPH for 65HP.
I take 180g/h/HP for fuel burn (or 395lb/h/HP)



5. Turbo cruise would mean Sport Pilot/LSA flights @ 8k-10k ft might
see 140-150 kts (GPS) ground speeds. ...just a guess. g

True, I like turbo for that... Consider that automotive turbo may stall
earlier than airplane ones.

We have some small diesel in Europe, but few are realy light and
reliable.
