I'd really appreciate some education on this subject.

Little do I know about diesel engines, my impression is that diesel is more efficent than gasoline engine. It seems many people would rather have a TD5..., we cant get TD5 here stateside, but what are the reasons we want them?

Here's what I know, diesel engine is more reliable, more fuel efficent, better torgue curve, better water tolerance, simple construction (less electronics) and can last a long time. The V8 has more power, it's faster and maybe quiter and smoother. But is there any other reason the V8 would be a better choice than TD5 in a Land rover? To me the diesel appear to be a better choice...

btw, what does the "i" stands for in TDi? in-line? and would that refer to the cylinders or the injection pump?

Thanks!

Turbo Direct Injection older engines were known as the TD

The TD5 is a computer controlled engine. Very hi-tech for a diesel(BMW?) Diesel engines without computer control are the ones that have the reliable, slow, noisy traits. Newer diesel engines are starting rival V8 power and performance; but with better economy.
So a TD5 in the US is a bad choice since no one here has the machine/computer to work on it. A TD5 in the UK would be a good choice. Now swapping to a 300tdi without electronics and with an upgraded turbo and intercooler...........hmmm

i'd love to have td5 - cleaner running than a petrol motor (so i hear), fuel is $1.60 or less a gallon, and i'd get 25mpg vs. the 15 i get now. sounds good to me!

Acoording to the spec, TD5 is "electronic high pressure direct injection". Is the electronic essential for engine operation? I though the fuel cut-off solenoid is the only essential electronic for a diesel engine. dont know much about modern diesel engine...

Even w/ the electronic, the diesel's mpg is still very attractive. I cant find any reason a petro V8 would be a better choice overall. I really wish LRNA imports TD5 here. How do the TD5 owners like their truck?

I have a Tdi - a 97 Disco.

Its a great beast.

Diesel 4wds are very popular in northern Australia (some extreme places only sell diesel). They're reasonably popular in the southern states. In fact, the TD5 outsells the V8 something like 3:1!

Diesel here hovers around 88/90 Australian cents/L, with petrol zooming from 79.9-97.9c/L.

My older Tdi gets 6-7L/100km on the highway, and no more than 10L/100km around town. The TD5 is slightly heavier on the juice, but still considerably cheaper than the petrol V8!

Diesel is good offroad too. Less power, but more torque, and available from just 1800rpm. Another nice feature is the economy - for a long weekend away all I need is a standard tank. Mates with V8 land rovers/Rangies, need jerry cans on board or have to stop more frequently.

Diesel runs cleaner (despite the soot output - the TD5 is very clean in this respect, however). It burns something like 90% more efficiently than petrol. So you're doing the environment a favour by (a) using less fuel, and (b) using a cleaner fuel.

I think the reason why you poor Yanks miss out on the diesel is the fact most of you still prefer a whopping great V8 petrol for your 4wds. There's a lot of people in North America and old habits die hard!

Ya'll welcome to come for a ride in my diesel when you're over here on vacation! ;-)

TDi = Turbo diesel direct injection. It's a special way of inducting the fuel directly into the cylinder instead of using a pre-combustion chamber. More power from less fuel.

TD5 = Turbo diesel, 5 cylinder.

Both engines are intercooled, 2.5L units. The TD5 unit has a bigger turbo that winds up faster (less turbo lag) and a faster, common rail diesel injection system.

TD5 is nearly as fast as THOR V8. Tdi is a lot slower, but still reasonably fast for a big 4wd wagon.

Thanks for the patience I'm really behind on diesel technology...

A 300 TDi w/ better turbo sure sounds nice. It'll be great to buy a really high mileage Disco 1 and put in a 300 TDi engine.

I also found this link on yahoo http://www.4x4enthusiast.co.uk/landrovers/story9.htm So TD5 have a confidence inspiring Lucas control module and common rail injection sys? The addition electronic is a bit of turn-off, but I think it still beats the EFI V8. A cleaner, more "civilized" burning diesel engine may have a better chance selling in u.s. Lets all write a letter to LRNA and beg them to import them stateside..., you aussie can write them too out of pity for the poor yanks and canadians.

I have a '97 TDi Man that has had a 200TDi turbo and manifold fitted, plus snorkel. I drove a lot of other TDis when I was selecting the vehicle and mine is noticeably quicker off a standing start. You can hear/feel the Turbo kick in a touch earlier, and overall it compares reasonably well to a V8 for responsiveness (granted, I'm not a rev-head). Fuel economy is good, 27-30mpg depending on speed/load/hills/aircon/driver mood etc. It cost teh previous owner about $3300 (Australian) ie about $12.50 US at current exchange rates. I am very happy with it and my local dealer tells me he has seen a few such conversions, all similarly successful.

Cheers

I have a 300TDi (98) Disco I, and the only thing I would swap it for would be a Disco II TD5.

I have heard from LR though that the TD5's are not as economic as the TDi's !?!

I get about 30 mpg, although I am due for a main service, so the filters need doing, oil changing etc., expecting that to rise to about 32-35 when I'm done.

Viva Land Rover!

I'm thinking about buying a series 1 disco with a ton of miles and having ECR install a 300 tdi. Of course I'm just toying with the idea right now and learing as much as I can about rovers. But from what you're saying it sounds like a good idea. Has anyone here done this?? Thank

They are doing one now.

Call and talk to Mike about it.
