Hi i e got a s11a 109 with the 6 cylinder 2.6 petrol. Would likento know what engines will go in without the need for an adsptor plate.


Does a 200 or 300 tdi match. Seams a good budget route as could buy a rooten disco and have all the bits. Also could test drive itnwhci h would be nice bonus.
Thanks all.
 
Just bought the landy as a true barn find as a winter project. She fired up OK after 20years rest but there is plenty of fine bubbles in the water. So suspect head gasket. Which ye I could fix but they are prone to breaking. And I would.like to afford to go past the end of my street. Opinion seams that they eat fuel and break and easy.

I love classics and understand the 2.6 is special. But that why I want a simple swap....so the 2.6 could be saved to one side so when petrol is back to 50p a litre.i could put it back in.

So what can I put in easily? Does the 200 or 300 tdi match the bell housing.

Many thanks
 
200tdi is pretty much a drop in swap for the 4cyl series motors, don't know on the 6 pots.
 
I don't think a Tdi will "drop in" as it does in a 2.25. In any case, a rebuilt 2.6 will be a much nicer engine.

Slightly tangentially, it's a shame Land Rover never made use of the Santana-built 6-cylinder variants of their own engines.

If its an all original barn find it deserves to be kept standard, what are you gonna be using it for? Daily drive or weekend toy? Classic cars come with classic reliability thats the charm for me 😄 but its your landy so good luck with whatever you go for 👍🏻
 
It's also no longer 2006, and there just isn't a ready supply of Discoveries with good engines available for next to nothing anymore. The Tdis are good engines, but they too are getting on a bit now and would need some maintenance before even thinking about swapping it over. The Discovery has much more sound insulation and higher gearing, so without an overdrive or 5-speed box, and in a vehicle with acoustic properties approximating a combination of a biscuit tin and allotment shed, you would be in for a very noisy ride with a Tdi. For the cost of the conversion, plus factoring in additional costs for unforeseen parts, a good service and general hacking around, you could do a really good rebuild on the 2.6 and not have to figure out how to install a clattery diesel of unknown condition.
 
I have a original six pot in my rebuild, I have no intention of ripping it out. If you are taking yours out let me know as the spares would be useful, some parts are hard to get these days.
If you have one and like mine it is the original engine it would shameful to remove it. They got a bad rep in the day because of lack of maintenance but any even remotely cosseted one should be fine these days. There are thousands of these engines in Rover P4's and they seem to be fine, I suspect it was farmers only sticking fuel in and not doing regularish valve gaps checks caused many of the issues.
The engine mount position, radiator, bulkhead, bellhousing (but not gearbox), floors and tunnel plus a lot of ancillaries are different.

If economy is your main criteria, perhaps a Toyota Yaris hybrid would suit better? Superb little motor.

Otherwise please consider that the loss in value you will cause by fitting a non original motor is much higher than the fuel savings, unless you are doing huge miles each year

Total cost of ownership is highly skewed in favour of originality.
 
Hi folks thanks for the replys so far.
All food for thought.
So to answer a few questions and statements.
Im not looking for great economy but do want to be able to use it. I love a classic as my daily drive. I only consider it breaking down if i have to get a tow home. Opening the bonnet and poking stuff and then carrying on is fun. If ya know ya vehicle then usually know whats wrong before coming to a standstill. Lol.
The newest motor ive had was a 2005 tdi galaxy that was good. But now new stuff is too many wires and nonsense. It might be less likely to break down. But what can ya do when it does???

When i say a true barn find it was. It was in a barn. Loads of bird poo and was nearly to the axels in hay and muck.

The chassis has had past work to good standard mostly. But body is also 70percent basket case.

Its mostly there but never going to be a show girl due to rippled and dented pannels. And if i change all those it wont be orginal anyway.

My wife has a 1998 110 300 tdi. And we really like that. Its not quiet in there compared to new stuff.....but we also have a ford transit mk5 with banana york diesel which makes everything seam quiet!

As said the engine seams good but very bubbly in the top of radiator. Next job is to get the clutch pedal working so can drive round a field to test the gearbox. Then i might know.which way to go.

Was the rover p4 engine the same 6 cylinder or was the landrover engine just based in it?

Some classics do belong in museums...but mine belong on the road being used. Thats why i buy rough but solid ones. As i do understand not to ruin a good orginal.
Thanks all.

I would put some serious weight behind this. If you look at the price of unknown tdi engines on facebook/ebay they have gone up in price hugely and then they will need at least a full timing kit. I have just fitted a 200tdi to mine that I got from a friend who is into land rovers. He had removed it form his rotten disco about 10 years ago and put it in the back of the shed for one of his but never got around to using it. I trusted him when he said it was a good unit that had just been standing so gave it a light rebuild/check over:
lapped valves and new valve seals
new head gasket
new glow plugs
full timing kit and idlers
new t-seals
checked main bearings - fine and did not replace
resealed sump
new alternator
new water pump
new crank damper
new belts

If it was a completely unknown engine I would probably have done more work to it, but it was a trusted good unit. As mentioned above for the price and time and effort of getting a tdi fit to use you could do the same with the 6 cylinder. a tdi in my opion is no longer a straight fit as you no longer drive the vehicle home and remove the engine. You will be buying an palleted engine most likely untested. (also don't trust videos of them running. I friend bought a defender with a 2.5na fitted that did not run when buying but was assured it was a simple fix and shown a video of it running a couple of days ago. On investigation the timing belt had snapped!)

Do not confuse originality with condition or concourse looks. Body panels, as long as the correct panel, can be swapped with no consequence. This is the same with nearly all classics but the fundamentals need to be as originally specced and preferably numbers matching if you really want high value originality.

Some more information on why you thing a 6 cylinder would not be suitable as a daily might be helpful. I would expect mid teens as the mpg on it which is not bad considering its age. I get low twenties out of my series diesel and get 26mpg out of my 200tdi 110 that does 30k ish miles a year. they are never going to be good on fuel economy but you accept it costs a bit more to run because it will cost less in repairs than a modern car is far more interesting to drive. There are far more pressing issue with why a series vehicle is not suitable as a daily than mpg: elbow room, waterproofness (lack of), needing to fondle you passengers left knee to get first or reverse, the list goes on.

Cheers for the heads up on finding an engine. My plan there will be to buy a complete disco. Main reason for change would be that ive never heard anything good about the 6 cylinder. Untill i put this post up then there seams to be lots of love for it. The enigine seams fine other than bubbles in the water but ive only run it once so far for about 30min. Trying to be optimistic about the bubbles as i had only just filled her up with water......but they are those fine little bubbles that cause concern. 20years sitting has likely let the head gasket go rotten. Used to do lots of work on classic minis and if left with water in for years it seamed to soak into the head gasket. New to messing wiith landies so not so sure.

I love 6 cylinders, best drive of any of the many Series I have owned.
Head gaskets are still available, and much less work to change than a whole engine.

Yes seen the gaskets listen on ebay. But will it just be the gasket, is this engine prone to head problems?
Cheers
