2.25 is a SLUG...... I had the 109 LWB, and it had all the 'go' of an asthmatic moped asked to carry a pair of beer swilling rugby players!
65mph flat out on the flat with over drive, the comfortable 'cruising' speed for a longer run, was about 55ish, while some hills, if loaded would have you down to a crawl, pondering whether you'd have to stop and try again in low-box!
Acceleration was glacial, and the overall driving experience was like one of those honda lawn mower (fixed speed engine) powered go-karts you get at a theme park, with a bar-stool instead of a bucket seat!
Lots of fun tho!
And worked well off road where speed not so important.
Petrols are SLIGHTLY more spirited... they can do more like 70-75 flat out with OD, and cruise at about 60, if you get them set up properly.
Ecconomy on either is chronic, and the diesels MPG isn't anywhere near what modern oil burners give, and these days, I dont think are likely to offer much of a saving over petrol.
'Typical' sort of figures for a petrol two and a quarter would be in the region of 20mpg, while for a deseasil two and a quarter, perhaps 25mpg.
Petrol, on a gas conversion is by FAR the more likely to give you useful savings;
Stil lonly likely to get around 20mpg, in fact a tad less as there's typically a 5-10% penalty on gas, which means around 18mpg.
BUT, gas is hovering around 51/52p (anything from 47 to 60 actually, but just over 50p is the more common), against 103 for petrol, and 106 for derv.
So its still 'roughly' half price; which means your 18mpg on gas gives same miles per quid as 30+mpg on petrol, which makes it a LOT more wallet freindly, and almost certainly cheaper than a deseasil.
There are people that will argue, that you can get 30ish mpg from a deseasil; and that LPG is 'duel fuel' and you have to burn some full Price Fuel on start up and warm up, and when / if you cant get gas, which depending on useage can knock the edge off it, and I wont dissagree; I dont get anwhere near the ecconomy I should from my Rangie, as I do a lot of short 'hops' which dont even warrant switching to gas; by the time its warmed up enough to evaporate it, I'm parked up and turning the engine off! But hey, when it comes to doing a long run, and I'm looking foreward to a 300mile round trip, of which only 5 miles is likely to be on FPF, and I can do that on one £40 LPG fills instead of one £90 FPF fill........ means I can actually use the darn thing!
And for all the tosh people spout about Diesels working 'better' off road; get them to qualify that, and normally the best they can come up with is the suggestion that they dont have an electric ignition to get wet and cut out in puddles or rivers........
Which is true, but then diesels stil have electrics and are not 'imperviouse' to water; drown a deseasil and, it will keep running, but after enthusiastic wading, I've hauled up and been unable to restart becouse its shorted the alternator or battery! at which point they start muttering about 'low down torque'.... which is a cop out, and more tosh; yes they do, at tick over, but then they dont have as much 'useable' power accross the rest of the rev-range, and where you dont have torque, you use the gear-box, which is why a series has eight forward gears; sixteen in fact if you have an Over drive.......
So, I guess, my advice is go petrol.
Only googlie, is converted motors; as said, neither of the standard engines are all that wonderful, and there are a lot of examples out there with alternative engines in them.
Perkins Prima Deseasil is one of the better oil burners; has a useful 90bhp, giving it better road speed than petrol, and is reported to offer as much ecconomy as you can get in a series; figures around 40mpg are often badied about, but take them with a pinch of, and a genuine 30 is obviousely available.
Rover v8, in 3.5 carburated form, curiousely not much less economical than petrol four pot, provided you dont thrash it, and genuine 90mph performance; and plenty of gas kits around for them, to bring ecconomy back into tolerable realms.
2.5 NAD, is a frequent one; most taken from old sherpa vans rather than Land-Rovers though, and completely defy the suggestion that Deseasils work best off-road! Went green-laning with one not long ago that came to an ignominiouse end in a big puddle, becouse the timing cases aren't sealed, and its timing belt slipped off its pulleys, in consequence to the entry of gloop!
Rated for offering equivilent performance to the 2.25 petrol, and better economy than the 2.25 Desel, they are vaunted as offering 'around' 30mpg...... but depending on how used.
In the equation; you are still likely to get as good or better performance and ecconomy from gassed 2.25P
TDI engines, FORGET them...... for some reason thet command a premium, but the actual conversion is a notoriouse one, and unless done well, which means not on the cheap, which also means effof rare, to the point of never happened, a conversion likely to give a lot of hassle when that mnotors power delivery starts mashing bits of the drive-line. Until then, though you'll get genuine 80ish mph performance, and 30ish mpg ecconomy... which gets dented very fast when you have to get a gear-box reconditioned!
De-Turbo'd TDi conversion, works better, but you only get around 90bhp, though still 'around' 30mpg, and isn't so hard on the drive-line, as its the way that the turbo effects the power delivery that makes the TDi so hard on old series transmissions.
BUT, given the choice, and fact that 'conversions' mean things dont look like the pictures in the book, and can be a night-mare to de-bug or renovate as you never know exactly 'how' a previouse owner did the job to begin with; sticking to the standard models is safest option, which brings us back to suggestion of gassed 2.25 Petrol.

Hi, just to have me pennies worth, I had a 2.25 diesel, I had the engine setup up well and very well serviced. It was surprisingly nippy around town and good in the mud, and pulling stuck cars last winter! I fitted an overdrive which made things better at speed but it defo not the long distance cruiser! Would sit happy at 65 with the o/d. I just kept my eye out for a good engine one, virually no smoke at all after it warmed up. On a run I could get near 30 mpg, and round town it used to surprise me as juice consumption being quite reasonable. Parts are cheap and plentiful insurance dirt cheap and its a very basic design which is easy to work on. A perfect choice in my eyes as a first landy for the young enthusiast and if your on a budget too.
Good luck whatever your choice,

The situation for series owners now is better than it has been for many years with so many TDI engines now available SO cheaply.Dead easy to fit,instant starting,very long life,spares availability,no insurance hassles,no finding somewhere to fit lpg tanks,no Channel worries and its a job which many LR independants will do for a resonable sum if you cant do it yourself.
If you are worried about gearbox life,dont use the intercooler and shut the boost down a bit.
I'm gathering parts to do an early tax exempt SIII,which I bought a little while ago.With a new galvanised chssis,brand new front axle,new Exmoor trim hood,polished body,(Dont like paint) and new fittings like stainless brake hoses etc,I think it will be a really useful bit of kit.(To last the rest of my driving life is the intention.)With one fuel tank that will give a good range that I can fill in any garage in Europe or beyond.Or run on veg oil etc.The engine is a 300TDI which is not as easy to fit but it was free so I'm willing to make a bit of effort to make it fit.
