Hi there, my name is Chris, just joined the forum living in Far East Gippsland Victoria, (Gods country). I am just about to by a 110 defender always wanted one.
Wouldn't mind some advice on what is the better motor, TDI or TD5 mechanical vs electronics.
Need a pros and cons list.
Cheers Chris https://www.aulro.com/afvb/images/imported/2016/05/668.jpg (http://www.aulro.com/afvb/editpost.php'do=editpost&p=1845749)

Having owned both, go for the one in the best condition and don't be afraid of electronics, as mechanical problems are the big killers in both engines, so the best service history is more important than which engine type.

Having owned, worked on and driven both (and still have both by the way), I have a strong preference for my daily driver and touring machine to be a TD5. I use the Disco TDi as a fishing/spotlighting truck.

Honestly, unless you are fording deep rivers daily and never tow or do highway driving then the TDi maybe a superior choice.

Others will disagree I am sure.

I think service history is the important factor here. At the end of the day though I think the difference between the two would come down to personal preference :)

Give one of each a drive, and see what you think of both :cool:

I am no Rover guru by any means. However, I have had 3 TD5s and a 200TDi.

The TD5 is better, in my view, in terms of 'driveability'. It is far easier to live with on a daily basis. The TDi was awesome up bush and belting around the farm. But in town, highway....it was painful after a while. I operate quieter, smoother, more comfortable tractors.........

The TD5 is tuneable and there are some amazing results (power-wise) to be had with the motor that make it a wonder to drive. I have spent a lot of time looking into these lately. Others can speak from experience.

I have never had a major let down with a TD5 over the years. Nor with the TDi however. Go drive both......l think that will help you decide.

As others have said, service history is very important.

Cheers,
Mike

As everyone here is saying, drive a good example of both and then pick.
People harp on about the Td5 being bad for remote touring because of the electrical side of things.
It's a load of crap.
Sure, you can get a lemon Td5.
Can also get a lemon Tdi.
If it's been looked after by the previous owner, and as long as you're prepared to do a bit of spanner work, either one will be good :)
The Td5 is quieter, more powerful, and a bit more refined.
First time I drove a Tdi i thought I had it in neutral. To say they're a bit of a slug is an understatement :angel:
Tdi from stock is probably more fuel efficient, but with a good remap or chip the Td5 economy will probably trump that of the Tdi.
I've had 30000km/1 year of Td5 ownership and haven't had any problems :)
Best of luck.

Id be looking at other things before the engine.
Pick the one with the best chassis/bulkhead, service history and general condition.

Both of them will do the job, I drive a 200tdi 110 and dont have a problem with the speed. Its fast enough to keep up with traffic and if i wanted to go quickly then id get a bike.

But ive only ever driven my 200tdi, a few series and a few pumas. Never driven a 300 or td5.

I've got a 300Tdi 110 and a TD5 D2a.

On long and remote trips I prefer the 110 (with overdrive), but that's probably because it's a Defender, rather than the choice of motor.

The TD5 is faster, both acceleration & cruising, which I found handy in getting through Sydney traffic recently.

The TD5 uses more fuel around town (auto vs manual Tdi), but less on the highway.

The plumbing around the TD5 can be simplified with total removal of all EGR piping, and this allows better access to the engine (belts etc).

Most electrickery issues I've had with my TD5 have been AUTO TRANS, ABS and CAN faults. If you're getting a Defender, the electrickery will not be as complex, but probably still worth getting a Nanocom or Hawkeye.

I was reading about the various performance spec'ed Defenders in the UK recently, and of all the diesels, including later ones, the TD5 always gets the best power figures and performs on par with V8s. One reason for this I read about was that the 5 cylinder engine always has a cylinder on a power stroke at any crank angle, thus giving better power & torque.

I have heard that a Tdi can be tuned to perform better than a stock TD5, but not better than a chipped TD5. So you can still get more power from a Tdi if that turns out to be the one you get. Variable Vane Turbos are now available for both engines as a bigger intercoolers. Military 300Tdis in the UK are renowned for their tuning, which I suspect is a combination of timing and fuel pump tweaks (that's a guess). Anyway, don't resign yourself to sluggish performance if you opt for a Tdi.

Servicing is similarly priced for both vehicles. A 300Tdi Service Kit (air, oil, fuel filters) costs 8.50 pounds and a TD5 Service Kit (air, oil x 2, fuel filters) is 12 pounds ex-UK. Either way, it's under $30 air-freighted to your front door.

The other things you'd get with a TD5 Defender are ABS and Traction Control.

Given that both vehicles are in similar condition with the rest of the mechanicals and the body,then I think it comes down to the individual and their driving style,if you are the type of person(like me) that is happy to cruise along and enjoy the scenery,and put up with the extra noise generated by the Tdi and really not want to go over 100-110Kph then you might like the Tdi,if you like it quieter and car like and have a bit more of a lead foot the the TD5 will be for you.Offroad the Tdi will lug a lot better at low RPM,which can be an advantage in rough terrain.The TD5 will work better in the sand where high range and the extra power will be an advantage.
You need to drive both and experience the differences for yourself.

Really ?

I've only ever driven a TD5 on road and it was a looong time ago.

I don't think the lady that drives the nearest TD5 Deefer would appreciate me bush bashing her pride and joy, although I'm sure Lee would give me an onroad fling in her car :D

either engine is fine, its the rest of the vehicle you need to be concerned about.

The electronics in the td5 is bulletproof where it couts most and any act of idiocy that takes them out will take out a tdi300 anyway.

IMO the 300tdi in STOCK form and WELL looked after probably isnt a bad engine for reliability, but given the conditions in Australia and if you intend to use it for work, that poor little donk is slow and under powered, plus you will need to up the service schedule for it to maintain its life.

I have never driven a Td5, but by all acounts from those who I trust, it is the better engine in every aspect.

LowRanger
29th January 2013, 10:09 AM
As I said,it depends on how you drive,if you cruise along at the speed limit,then the Tdi is fine,but lets not forget that the Tdi vehicles are usually a lot older than the TD5's and the rest of the vehicle tends to wear out a lot quicker than the engine.
My 200Tdi has nearly 400,000km on it,and it gets a hard life,is still all original,and there are many many more out there just like it.Maintain the vehicle correctly and it is just as reliable as anything else out there.In steep rocky terrain,give me a Tdi over a TD5 any day.
If I wanted a nice taxi,then a Disco with a TD5 would be a nice vehicle:p
Your 2.8 would be nice though :D

I am not fooled by the hype,I just like it for its simplicity as a replacement for a Tdi along with the extra power that it gives,not interested in trying to make a sports car.

Yes Petes' Td5 does go well,I have been out with him.But it still doesn't change the fact that in steep rocky terrain,particularly when descending very slowly with your foot on the brakes,that Td5's have a tendency to stall,where a Tdi will just turn over slowly and keep running,giving total control.Also on climbing steep rocky terrain,the Tdi again will just turn over,where the Td5 will either stall or requires more throttle and therefore breaks traction.And in these situations it is all about maintaining traction and applying power to the ground,even with as little power as there is from the Tdi.In faster type terrain,then I agree that the Td5 will be superior due to its extra power.Depends on where you drive and how you drive:cool:

Oops :eek:

I agree, a 2.8 would be nice, all the things that worry me about a Tdi are addressed but they are bloody hard to come by now, unless you speak fluent Portuguese and are able to liberate one from a Ford wrecker in Sao Paulo :(

Good info there mate. I guess being the same capacity with one extra pot, the Td5 would be expected to be less torquey than the Tdi if all things were equal. This is where I would have expected the fuel delivery differences and ecu to come in, but by the sounds of it not as much as I would have thought.

Not to derail completely, but what Turbo does the Td5 have? is this an area that can be improved on like fitting a VNT to a Tdi??

A decent VNT should make a big difference, on both engines.

IIRC the TD5 uses a GT2025, an updated version of the Tdi T250-04.

uninformed
29th January 2013, 04:41 PM
ok, well I kinda would have thought that the Td5 have a VNT, but I guess its a little older than that. Is there one that bolts up without the need of a new manifold? Does the Td5 have a pressurized wastegate like the Tdi, and there fore the 2.8tgv turbo be a good candidate due to the fact the VNT is pressure operated unlike most which are vacuum?

btw, how about we con Lara into a group buy of crank/conrods and pistons to make 2.7Td5's :cool:

I just sold my D2 which had two catastrophic engine failures, one was a con rod letting go, the other was a broken rocker, which dropped the oil pressure long enough to destroy the crank. One had 180,000 km, the other 140,000.

My TDi has 308,000 and only had the water pump replaced at around 200,000. It has put me off buying second hand as I bought the Defender new, but the D2 second hand and you won't find a new TDi or TD5, hence my advice to buy the one in the best condition.

Buy the one with the best recorded service record. I have a 1999 TD5, 357,000 km's on the clock, 2 owners before me, one the Illawarra Council, the other, a pedantic Pom.

Bob, how will that stop a catastrophic failure as Jeff experienced ?

My 300Tdi had been very well looked after, using only the best HD diesel syn oils since I bought it, etc, etc yet the big ends failed.

Not wore out, failed, as in the overlay delaminated.
It's still a miracle I didn't destroy the crank. (chalk one up for stupid exxy oils)

Clearances were correct, nothing was ovalised, yet on every shell the overlay fell apart.

Bad bearings and bad luck on my part, nothing maintenance related.

Mains were and are still fine @ 300,000km.

As said already, both engines are inherently solid and durable as long as they were serviced regularly. Most importantly on Tdi-engines, make sure that the cambelt has been changed, otherwise the engine is bulletproof. Td5-engines can have some problems with the fuel pressure regulator, wire loom and, on early examples, the cylinder head dowels.

I have a 300Tdi in the Disco, the engine has provided me with trouble free service in 17 years now (unfortunately, the same cannot be said about the vehicle's other components). The Td5 I have in the TR has had the wiring loom and the pressure regulator problem, both easily sorted.
Although the Td5 is more driveable, I prefer the Tdi for its simplicity, the lack of all electrics and the lower fuel consumption. The Tdi is by no means a rocket, but not at all sluggish as described by others. You will always be able to keep up with the traffic, I am still one of the quickest on the road when driving the Disco :p:o:D:cool::angel::twisted:.

Jeff I think what bob meant was the Td5 is like any engine.
A lack of maintenance will cause it to suffer.
At the same time, Bob I don't really think it's fair to comment as unless you and Jeff are neighbours and do the landy work together, you don't know how Jeff treated his engines.
As such, it's not fair to make comments that suggest he didn't look after them :)

Both suffer from their own individual shortcomings

I have a 1999 TD5 Defer. 358,000 odd kms and going strong. Well maybe a suspect head that needs attention. I agree with Wayne that the TD5 needs a little berries to avoid stalling when crawling. The problem I find when crawling is that the engine, to me, seems to want to bog down and stall, so you give a little throttle. The engine kicks in and you go from avoiding stalling to rocketing up the hill. Classic example was Lambrover in his TD5 130 at Wheeney creek last year. If he had wings he would have launched off the top of the rock. Others may have a gentle right foot and avoid my experience. I'm chipped so I don't know if that has anything to do with it. The other way is to not touch the throttle and leave the anti-stall to walk you up. I'm yet to learn to trust that the anti-stall is better than my right foot.

Don't concern yourself with any negative comments about reliability of the TD5 or its electronics. Like previous comments all engines have their shortcomings but with a regular service most engines will repay you in kind. As for the electronics, the problems are well documented and relatively cheap to resolve. That said, if you go the TD5, spend the $300 to have a mechanic drop the sump to check and loctite the oil pump bolt. Cheaper than an engine rebuild. The head is also a known weakness.

As for daily driver, if you using a defender as a daily driver you must have sensory deprivation. Lets be frank, it's a pig to drive as a daily driver. Don't get me wrong I love my defer and buy lotto tickets to buy a puma as a daily driver, but it's not the benchmark for comfortable convenient relaxing driving.

I think the behaviour you describe when in low range where using the throttle sends you into a launch pattern is an early Td5 trait. They sorted out that issue in the later ones.

Bluntness is a trait I picked up in the military, I try hard to be nice, but evil Bob keeps popping out. What I meant was, properly serviced, and if minor leaks, etc , are kept on top of, the TD5 , in my experience, is as good as any . We've been to the Gulf, and over most of Qld, without a problem. To qualify my statement, I must say I do not use my D2 for extreme 4WD'ing. But it has taken me thru some rough country, [& back:)] Having said that, I am a lotto win away from a Defender 130 twin cab chassis.

Bob, how will that stop a catastrophic failure .
You left out " the one with the best service record". From new. Nothing will stop the failure of an engine with a suspect part. Any engine. The other point to remember is, take an engine designed for certain paramaters, chip it, put an aftermarket intercooler, plus other mods. to "beef" it up, then tow a large van, or go charging up huge sand dunes, and the resultant EGT, must be detrimental to all aspects of its operation. You can not expect a TD5 to be as powerful as a V8. Simple. Both have their place, the LR engineers designed the TD5 to do a job, and it does it better than most engines in it's class. The problem comes when we decide to be pseudo engineers, most of don't really have a clue. Now, before someone jumps down my throat saying I've been "abrupt", " nasty" or just plain " mean", this is just my opinion, not directed at any sensitive souls, God bless them. Bob

<snip> The other point to remember is, take an engine designed for certain paramaters, chip it, put an aftermarket intercooler, plus other mods. to "beef" it up, then tow a large van, or go charging up huge sand dunes, and the resultant EGT, must be detrimental to all aspects of its operation. You can not expect a TD5 to be as powerful as a V8. <snip>

I do not concur.

( the threads not about Td5 vs V8 but since its been bought up)

I have a MY05 Defender Td5 , Stage 1 chip , decat, EGR removed, In that trim it has similar power to my P76 4.4 V8 109 but at least twice the fuel economy. Towing my 1.8 tonne van I felt the exhaust temp was hot so on advice of AULRO I fitted an EGT and found temps got up to 850 on a hard pull up a steep hill.

Fitted Alisport intercooler , put 3" inlet hose from snorkel to air box, and did airbox mod, EGT up same hill with Van WOT = 750 ,

Today I got the centre muffler removed put a 3" hotdog in its place , maximum EGT I can get to is now 690 - towing the van.

The "beefed up" Td5 is now much less stressed and cooler running

The Td5 now absolutely puts both my previous V8 Landrovers to shame in performance stakes , ( the other one was a Ford 5 liter V8 in a 90 hybrid) and makes them downright anti social in the fuel economy stakes. I realise they are both dinosaur carby V8's but still you could never get a modern petrol V8 to be as efficient as a Diesel when towing.

( imagine the grunt with a Stage 2 chip & VNT , but for what I do I don't need to go there)

Things I hate about the Td5

Theres nothing in the engine bay to to push or pull to make the engine rev up & down whilst listening to that sweet sound (like a throttle cable)

The Aucostic Engine cover & Turbo cover , stop you seeing & appreciating the the engine .

Things I Love about the Td5

everything else

Take the acoustic cover off :D

TD5's are great once you fix

Loctite oil pump bolt
Headgasket/head
Timing chain tensioner
Fuel cooler leak
Exhaust manifold deweb/deck
replace turbo
Injector loom replace
Dual mass flywheel

Has anyone mentioned yet that a worked TD5 sounds a million times better than a worked Tdi.

No, but I've always said a Tdi with a big bore exhaust sounds like :toilet:

I got to hear mine again the other day as it went for its brake test.
It just sounds like a tractor :(

You left out " the one with the best service record". From new. Nothing will stop the failure of an engine with a suspect part. Any engine. The other point to remember is, take an engine designed for certain paramaters, chip it, put an aftermarket intercooler, plus other mods. to "beef" it up, then tow a large van, or go charging up huge sand dunes, and the resultant EGT, must be detrimental to all aspects of its operation. You can not expect a TD5 to be as powerful as a V8. Simple. Both have their place, the LR engineers designed the TD5 to do a job, and it does it better than most engines in it's class. The problem comes when we decide to be pseudo engineers, most of don't really have a clue. Now, before someone jumps down my throat saying I've been "abrupt", " nasty" or just plain " mean", this is just my opinion, not directed at any sensitive souls, God bless them. Bob

Mine had a great service record, and wasn't chipped or modified at all. I pulled a 1200kg trailer, but never thrashed it. If I seem a little sensitive about this maybe because I lost around $30,000 on that car. The TDi Defender did the same job just a little slower and not as comfortably.

we have had both in the family, i never really thought the tdi was sluggish for its era, its a diesel but driving any other 4wd of the same age made the disco feel fast.
the td5 has been very reliable, these type of unit injected engines have been used in much bigger diesels for years before the td5 came out and prove the engines long life and reliability.

I have a 2003 TD5 and as per the above list have had the fuel cooler and injector loom replaced, mine is an auto d2 so the flywheel doesn't come into it. The rest have not been an issue.

The 94 300 Tdi defender has had a split turbo hose and a change of the bracket for the injection pump, timing case, and associated components. The gbox however has been a different issue, two rebuilds and looking at a third in the near future. The first two rebuilds of the cog box where not elective surgery either, due to one fail to proceed and a very noisy input to laygear self destruction issue.

Both engines have had issues within the engine bay, the 300 tdi repair costs where higher due to the timing cover/belt etc issue.

Both engines have issues which for some have turned into major ones, which ever you get, you need to make sure have the ones with the greatest potential to hand grenade you motor sorted. Lack of maintenance of the cooling system in both engines will result in likely destruction of the engine. Head gasket replacement is not unusual with either due to poor cooling or failure of overflow bottles.

That's because a worked Td5 IS a million times better than a worked Tdi :twisted: :angel:

Old diesels were all noisy and so the Tdi was perfectly normal for its time. In fact, just yesterday someone started up an old truck and I had to go and look as it was so noisy I couldn't figure out what it was. Tractor? Dump truck? No - just the Defender the neighbours have been trying to sell for ages. (Red five door, Tdi, $9500, shame I don't have any money!)

Anyway, in my case, having champagne tastes but a cordial budget, I would look at the potential cost of what may happen to each engine. I've been reading about TD5 crankshaft dampers and flywheels and so on, and it's terrifying.

I should print up a price list to show the wife when she complains about my V8 rebuild.
