Hello Derek
It is the torque that is the most important part of an engine.Low RPM
high torque.
The 4 cylinder has more torque than the V-8.
Example you ever drive a diesel car and you do not have to give it any
(gas) pedal in first gear to get moving.If you do the same thing in a
petrol vehicle you have to give it gas (petrol) of it will stall.

My V8 Discovery happily pulls away from a standstill without giving it
any gas (either petrol or LPG). Of course the diesel will five better
fuel consumption that the V8, but run the V8 on LPG and the cost/mile is
very much the same.
If, as you say, torque is more important than hp why make a point of
saying "Discovery has more power than with the original V-8"?
Anyway, these engines are already available through a UK importer for
much the same price, including delivery to your home and all taxes.

I was merely being pedantic pointing out more power is more power and more
torque is of course more torque.
Being mindful of this Range Rover fitted a nice automatic box (only rarely
a manual box on the later cars) on the V8's and having selected drive they
quite happily pull away with no extra throttle sufficient torque imo
although the peak comes in higher at around 3000 rpm perhaps I should quote
the US spec figures P38a ( mk II ) to make the point
Power (1995-98) 190 hp (4.0), 225 hp (4.6) @ 4,750 rpm
(1999- ) 188 hp (4.0), 222 hp (4.6) @ 4,750 rpm
Torque (1995-98) 236 lb-ft (4.0), 280 lb-ft (4.6) @ 3,000 rpm
(1999- ) 250 lb-ft @ 3,000 rpm (4.0), 300 lb-ft @ 2,600
rpm (4.6)
of course the penalty is the fuel consumption not really an issue in the US
(fuel cost per gallon = uk cost per litre ) which explains the low numbers
of oil burners over there. I really wouldn't consider converting a petrol to
derv when LPG has more benefit without the performance loss and having to
change the autobox ( and some ancillaries) because the variation would not
get the best of a diesel tending to over revs on the standard box.
Interesting tho turbo 2.8s are quite popular series conversions usually
toyota or diahatsu units which are available for quite reasonable money over
here
