Then again, its not a JEEP engine anyway. Its European, V-Motori, - Wonder how it would go in a Rangie ?

Okaaaaay... whilst we're comparing apples with green & red round things...
Dug up my old Black Book, and the 1979 CM valiant I used to own, and did over 200,oookm in, gave me 22.4 and 21.1 mpg (12.7 l/100km and 13.369 l/100km) on a return trip to Adelaide in Xmas 1983/84.
This included several hours driving on a melting highway. A VERY hot day. Naturally the air-con was on 110% of the time.... and driving fearfully fast on the way home... Suffice to say that the new South Australian built HD gas shocks were fantastic at over 160km/h.....
When you consider that the 4.0 litre hemi was pre-1978 technology, Carby, standard exhaust, 1.5 tonne car with solid SUN VISOR... never mind the rain channel !!! and carried nearly half a tonne of spares, tools, water, oil and petrol (40 litres at all times) as well as my rotund self... it mileage was quite acceptable.
And no, the ELB was not the be-all and end-all, though I could never stop the engine no matter how much I hosed it down, though a fire-hose manage it by unseating the dizzy cap. I still reckon he hit it with the nozzle.....
In the month before selling (355k+) , it gave me 20.5 mpg / 13.9 l/100km.
So, if we whizzed back in time and put the same tired old design engine into a constant 4WD vehicle, and took 3 to 4 mpg off it... for the extra drag of 4WD and 400kg, then the older crude & rude Yankee engine still outperforms the Pommy Perfection !
My 3.9 litre has nearly TWENTY years better technology, fuel injected, hopefully better exhaust system, better gearbox, and only a few hundred Kg's heavier... and grudgingly gives 14 mpg (20 l/100km) to 16 mpg (17.4 l/100km) and only has a pathetic little rain channel above the windscreen to drag it down... (yes, PhillipI had to go outside just now and check !! ;-) )
- I really don't think Rover deserves any sympathy, hence my leaning toward diesel.
The only real choice is whether the 300tDi or something foreign...Like Isuzu, but am advised that it may not fit into the engine bay...
Or put it onto LPG with lots and lots of gas tanks everywhere to give me a decent range out of the metro area...
Or sell it... VERY tempting !
On the bright side, I've been told by many folk that the 3.5 V-6 Jackeroo I was looking at had a worse thirst...
I would'nt be so grumpy if it gave me the power to balance the equation, but it fails miserably there too.
Its still NICE to drive, sort of.... ;-/

SubscriberYou could just go and buy one as the 89-91 RRC had a VM diesel (2.4 and 2.5), which was the great grandfather of the current one in the Cherokee.Its European, V-Motori, - Wonder how it would go in a Rangie ?
BUT you should maybe ask people what they think of them!!!!

I have an 87 classic with a 300tdi and 5 speed out of a disco
In it. The pump has been tweaked and it has gas injection. It averages 12-14l per 100km with a best of mid 10 occasionally achieved. It cruises much better than my brothers 93 classic with the 3.9 at 110kmph maintaining speed up and down hills in fifth whist his searches up and down trying to hold speed. Although his does accelerate a little faster.
Unless you can do the conversion yourself I think you will need 10-12k to do the conversion and get gas injection.

Hey Superquag, your 78CM Velo
Did it have this engihe it ?
245LC (Low Compression) released in 1977
Seeing your Rover engine is only a ex BOP from 1961 buick
- Bore Size: 3.76 (95.5mm)
- Stroke: 3.68 (93.5mm)
- Compression ratio: 7.6:1
- Power: 130 hp (97 kW) estimate
- Torque: 180 ft·lbf (240 N·m) estimate
- Intake valve head diameter 1.845 inch (46.9mm)
- Exhaust valve head diameter 1.500 inch (38.1mm)
then the old 1961 engine produced (Fuel injection does nothing for outright power )
61BuickSpecial155 @ 4600210 @ 32008.75:12Bbl
62OldsmobileCutlass185 @ 4800230 @ 480010:25:14Bbl
63OldsmobileJetfire215 @ 4800300 @ 320010:25:1
so thats the Velo's at
215 140 HP
245 165 HP
245 LC 130 HP
265 203HP
265 E49 Charger 302 HP
Now with average carbed 3.5 in the 140 to 160HP range
and the 3.9 in the 180 to 200 hp range
then really the old Velo hemi is and was nothing special .

Have you ever looked on youtube and seen that 3.5l td mazda running thats the way i think i am going as you can get all the bits and adapters from uk or buy a whole car for a few hundred pounds an ship it over seen quite a few on ebay since i have been looking they used to do a lot of those conversions, M & D engineering.

Good grief NO ! - Mine had the 160 hp high(er) compression engine.
I agree 100%, the Valiant Hemi was rather ordinary, even in its time... - You needed Eye of Newt and skin of Toad to get the ELB working perfectly, which then could give around 14 to 10 l/100km. Sometimes.
I was more making the comparison between a crude, rough, very primitive and unashamedly thirsty Valiant engine.... and the supposedly New! Improved! Whiter than White, betterer 'cos ROVER had continued with R&D etc ex-Buick V8...
In around 20 years.... there has *NOT* been a decent level of improvement, certainly not IMHO to justify keeping the 3.5 / 3.9 instead of either using someone elses tried and proven engine, or starting again.
As a friend of mine (Rover and Triumph 'Tragic') says.... "the Range Rover is a car designed by a Genius, -- and built by ***s"
To which I'd add...with parts supplied on the cheap by incompetant Management.
It was always shoddy workmanship, cheap and nasty and/inappropriate quality parts, and most importantly, pig-headed stupid management that ran Land Rover down to the embarrasing sell-off.
Credit where its due, - LR's Marketing Dept IS the best in the world.... Who else could sell "Unreliability" as a desirable thing ?
Putting ANY other engine in a Range-Rover where appropriate should be encouraged. - A 3.5 MAZDA diesel in any LR would be a Good Thing.
I could almost have tolerated the thirst... if LR had put a decent sized fuel tank in the Rangie, give us masochists a decent range..without spending yet more money on custom built/extra tanks...
Even my 1989 Mitsi Pajero has more than 91 litres (petrol or diesel).. and when LR brought out 'their' Pajero, (Disco I) the tank was still smaller...
Anyway, thats my rant for the night !

Rovercare ."Fuel injection does nothing for outright power? your kidding right?"
No , not Kidding , one trip to the dragstrip will demonstrate that .
Although modern EFI , (as distinct from MFI)is far better for all the other reasons , such as meeting pollution DRS, reliability,economy,tuneability,startability (made that one up !) outright control and 100 other reasons , it still wont make an engine develop more peak power than the appropriate Carb , perhaps systems like the VE11 SIDI is the only example, but that required a radical redesign of the heads. (yeah make them like a diesel ,LOL)
As for Superquags Story , just demohnstrating that the original 1961 BOP 215 engine made more power than his 1994 EFI 3.9 and was comparable in power to his 1978 CM Velo .
So what Superquags says about , levels of improvement ,cheap parts , useless management , selling unreliability , design by genius , etc etc Im going to have to agree with !!

Ahh, wont make a lick for "outright: HP yes, but across the board, Venturi metering vs ECU, that thar puta is betterer
Chuck in ECU controlled knock retard and your on a real winner, not that the 14CUX has them fancy dangled fings
