One drawback would be, if I was driving that Disco, it would have less range than an EV! :burnrubber::burnrubber::burnrubber::burnrubber:

Love it, nothing improves an UNESCO area like a 5L V8 Supercharged.

No kit required, its all bolt in with the right donor.

I was referring to the electrical stuff. Perhaps "kit" was the wrong word. Perhaps "software" would be better. Dunno.

Still nothing much required, the D4 already came with a 5.0V8 so a donor RRS engine will drop right in.

Only if you're swapping like for like, diesel to V8 petrol will require a bit of an electrical faff.

[discomatt69]

That’s why they change the wiring loom and so many modules

Possibly more than a "bit".

Personally I'd prefer the TDV8 option. I don't need stupid fast these days.

Nor do I, but it's fun occasionally. [bigwhistle]

[cripesamighty]

On the video he said it took them 4 months to get the electrics side of it sorted and even now it still throws up codes but is driveable...
I would love the TDV8 option if it was available.

[loanrangie]

There is a D4 in the US with the rrs scv8 pushing 800 hp.

[goldey]

Put me down for one of the TDV8 conversions too.

[discomatt69]

My thoughts, D4 with blown engine worth $2000, D4 running with 200,000km worth $20,000, D4 200,000km with V8 diesel conversion??? 50k probably because we all know what an amazing car that would be
how much would people be willing to pay for a converted and well sorted V8 diesel D4?

I think you’re dreaming of $50k for the V8

[RANDLOVER]

I think you'd probably have to compare them to RRS 3.6 diesels, and maybe add a bit of a premium for the extra space and novelty value.....carsales.com.au (https://www.carsales.com.au/cars/land-rover/range-rover-sport/tdv8-badge/)

[discomatt69]

In my mind there is no comparison with a Range Rover and a Disco 4
no winch bars , no rear bars, no long range tanks, limited roof racks, no full chassis , some with alloy chassis so easily damaged when recovering if really stuck, even more electrical crap to go wrong and cost more, less space and less load capacity
The Rangie certainly doesn’t suit my needs

[Graeme]

The L320 RRS has a slightly shorter version of the D3/D4 chassis.

Well we sat down & worked out a price guide for the TDV8 conversions;

A rough guide of costs for these jobs;

3.6 into 2.7 D4, ~$31,000 (2010-2012MY, 6-speed)
3.6 into 3.0 D4, ~$40,000 (2010-2012MY, 6-speed)
3.6 into 3.0 D4, ~$43,000 (2013MY, 8-speed)
4.4 into 3.0 D4, ~$52,000 (2010-2012MY, 8-speed conversion)
4.4 into 3.0 D4, ~$49,000 (2013MY, 8-speed)
4.4 into 3.0 D4, ~$50,000 (2014-2016MY, 8-speed)

Obviously this doesn't include the cost of the vehicle itself.

The exact cost will depend on what you pay for the engine & transmission, esp for the 4.4 the price of these engines has gone nuts, recently one was sold out of a wrecker here in Sydney for $25k, just the engine with turbos.... the 8HP to suit the 4.4 is typically $5k now. To buy a 3.6 engine & transmission is significantly cheaper, or you buy the whole vehicle just the engine & gearbox.

If you are starting with a 2010-2012 3.0 and go 4.4, then the conversion from 6HP to 8HP is part of the job, if you wanted to put an 8HP behind a 3.6 in a 2010-2012 it's also possible for additional costs. 3.6 into 2014-2016MY D4 is not feasible because of electronic architecture differences.

Supply of engine & transmission, control modules
Sensible work done while the engine out, turbos & injectors refurbished, new hoses, etc
Wiring swap or modification in engine bay & cabin as needed.
Custom exhaust & other custom work e.g. engine mounts for 4.4 are full custom.

Some cost recovery may be possible if the original transmission & engine are good (usually they aren't hence the conversion).
And the old turbos of the 2.7 or 3.0L provided as cores to for reman service but not a lot of $$$ these days.

The main thing is this is not swapping all the RRS wiring and modules into a D4, the D4 still thinks it's a D4 so the rear aircon, tailgate locking aren't messed with, it still shows a Land Rover logo on the touchscreen not Range Rover, the VIN when you plug in with a scan tool is the original Discovery 4, not a donor RRS. This is the way to do it properly, and it's how we do it. The guys who don't understand the software in these cars swap everything over.

For a supercharged V8 D4 it's only sensible to start with a 5.0 V8NA 2010-2013 or a 3.0 V6SC 2014-2016, throwing in the conversion from diesel to petrol and all that just doesn't make sense. And if you start with a 5.0NA or 3.0SC then you don't need to swap the transmission, the original 6HP28 or 8HP70 bolts up, just needs a modified tune. If you're converting from diesel to petrol you need not just an engine, but a transmission too, and everything else. Not worth the bother. Budget $20-$25k for a good low km 5.0SC from a wrecker. Otherwise these are the easiest of all the conversions (to do the job, perhaps not to pay for). $10k in labour & programming is realistic.

[Cambo_oldjaguar]

On the video he said it took them 4 months to get the electrics side of it sorted and even now it still throws up codes but is driveable...
Our partners in Colorado (we provide the software solution, they do the mechanical/electrics) are doing the conversions in a working week. 5.0NA or 3.0SC, to 5.0SC, no fault codes, no errors on the dash, they just work.

4 months is a joke.


I would love the TDV8 option if it was available.
It is, which TDV8 would you like 3.6 or 4.4?

[cripesamighty]

If I won Lotto tomorrow I would take the 4.4 TDV8. Of course I would have to buy a D4, but I would still keep my D3!

[Graeme]

Just buy a 4.4 TDV8 L322.

maybe a stupid question but why so much for the 4.4 conversion?
how much is labour?
How much of s allocated for the engine?
in the video posted they have the majority of the job done in 3 days
I would do the conversion if / when the 3 l dies because I love the D4 but 50k is just beyond logic and not worth it or is that the point because it’s too much hassle

I dare say the donor parts are more expensive in AU compared to the UK. Over there, used cars are much much cheaper, and the land rovers more common than on our shores. High supply, low demand.

Add to that the R&D that OldCambo sound to have done to develop a 'better' outcome than a disco that thinks it's a range rover, which should rightly see an uplift.

Without any research to back this up at all - it may be cheaper to simply import a converted disco from the UK? :P

[Cambo_oldjaguar]

As I mentioned the 4.4 engines are going for $20k, one recently went for $25k

You need the 8HP from the 4.4 as well the going rate is $5k for them.

So there’s $25-$30k straight up.

The custom engine mounts to make it sit in the D4 are $2k

You’ll need a lot of additional small parts & modules out of the donor car, like the glow plug modules & wiring, airboxes from an L322, this, that, there’s $5k in sundry parts easy.

From our side the engine & trans tunes, and other software mods are $2.5k

Pretty much every hose & tube under the bonnet is modified or custom, which costs $$$$$, we allowed $3k there.

It’s not like a 3.6 which drops in on factory mounts and factory hoses & fittings line straight up.

It all adds up.

[Cambo_oldjaguar]

Here's one prepared earlier

193593193594193595

There's some videos of it running & driving too but you can use your imagination.

This is a 2015 Euro5 D4 in the UK, 4.4 & 8HP from an L322, fitted with the sump from an L494, and a lot of custom work.
Jon at Mersey Discovery Land Rover, Discovery & Range Rover Specialists Wirral (http://www.merseydiscovery.co.uk) did all the mechanicals, fabrication & wiring, we did the software.
It's registered, engineered & road legal in the UK as a 4.4, was the first one done outside of Russia that actually drives.

There's a couple others underway in the UK, and one here in NSW, but it's a slow burn on that one.
The costs and effort make this conversion make it a vanity project at best.
It doesn't make any kind of financial sense but if you want it and are willing to pay for it, you can have it.

[Cambo_oldjaguar]

As for 3.6 TDV8 D4's, there's Matt Wiggles UK Auto Spares | Adelaide SA (https://www.facebook.com/share/1ESoBQj2xx/'mibextid=wwXIfr) 2012 D4 in Adelaide.

Was originally a 3.0 TDV6, now a 3.6 TDV8.

193596193597

The thing that a lot of people don't realise is that the 2.7 & 3.6 have Siemens engine management, and the 3.0 (and 4.4) are Bosch, and this is why it's a complicated job to convert a 3.0 to 3.6. The ECU's and therefore the wiring at the ECU, on the body side and the engine side, are completely different. The best and easiest starting point for a 3.6 conversion is a 2.7, because you don't need to touch a thing on the body side of it, and the 3.6 engine harness just plugs straight in. Unfortunately it's the 3.0's that go bang 99% of the time so the most common request is starting with a 3.0, anyhow...

Matt's conversion is that it still a D4, you plug in a scantool and it identifies as a D4, the VIN is the original D4 VIN in the modules, the rear aircon works, the tailgate works, the logo on the touchscreen is Land Rover not Range Rover, it's a D4 with a TDV8, not a D4 body with RRS wiring & modules.

Now because it was a 3.0L the dashboard had to come out, and the wiring harness' behind the dash from the BCM to the PCM and the IPC had to be swapped out with one from a 2010MY 3.6 TDV8 L320, not a fun job. Now in theory it would be possible to just cut/crimp or re-pin the connector at the PCM and the connections at the engine bay fuse box, but since he had a donor stat write-off 2010MY L320 3.6 TDV8 sitting there, well it was easier to make the swap. But you need to do something like this either way because a Siemens PCM will not plug in where the Bosch was....

The 6HP28 transmission from the 3.0 had to be swapped to the 6HP26 from the 3.6, this is another thing a lot of people don't realise, you're not just doing an engine swap, it's a transmission swap too.

Anyway this D4 of Matt's is the shining example of how to do the 3.6 TDV8 conversion right. And the cost reflects that.

[Cambo_oldjaguar]

There is a D4 in the US with the rrs scv8 pushing 800 hp.
There are about 10 or 12 D4's in the US & Canada now with 5.0 supercharged motors, but sadly none of them are making 800hp.

It's the typical American hype, we told them it'll make 650hp if you do this, this and this, but they didn't do any of that, and then decided to call it 695hp, which is nearly 700hp, so then it became 700hp, I am not sure where the 800hp comes from but wouldn't surprise me if someone is claiming that lol

There's a workshop in Florida did 5x of them so far, one this week in fact
Another workshop in Colorado did 4x of them so far, one last week and they have another on the go for next week.
One workshop in Canada did one a couple of months ago.
And a workshop in Georgia did one as well a few months ago.
The usual arrangement, they do the mechanicals/wiring, we do the software.

That's 11 ? or 12 ? or I'll just round up like the Americans do...

Does this mean that the 3.0TDV6 to the 4.4TDV8 should also be reasonably straight forward much like the 2.7TDV6 to 3.6TDV8?

[Cambo_oldjaguar]

Does this mean that the 3.0TDV6 to the 4.4TDV8 should also be reasonably straight forward much like the 2.7TDV6 to 3.6TDV8?
Short answer is no not really.

While the 4.4 ECU will plug in to the body connector of a 3.0L vehicle, and that is less of a complication, the rest of the conversion (mechanicals) is far more complicated with custom engine mounts, hoses, ducts, pipes, other wiring in the engine bay, and conversion from 6-speed to 8-speed if you're starting with a 2010-2012 model.

Since the 4.4 was never in the L319/L320 platform, technically it doesn't fit, you have to make it fit, and then make everything else fit around it.

[discomatt69]

Still doesn’t make sense to me, more than likely just my ignorance but in one of the videos posted they do the basic change in 3 days, body off, engine and wiring removed, new v8 and wiring in, body back on and started, done so no more than a weeks work.
really struggling to work out why it’s so expensive
in my mind who cares if the vin changes or the car thinks it’s a Range Rover, as long as it’s reliable the other bits don’t matter
please educate me on the finer details as I was really hoping this was viable option but the prices suggested it’s just not viable at all

That was the 3.6 which just bolts in, they didn't show the instrument panel so it might've said RR. I know this is a problem as years ago I saw a similar conversion in one of the magazines LRO/LRM and that Disco did think it was a Range Rover.

[Tins]

Reckon Cambo is correct about "vanity project", if the goal is to repower a loved D4. Surely a 3.6 would be sufficient for that purpose? Not many people would call a D4 underpowered with the TDV6. The TDV8 would surely be ample, especially the torque.

Anyway, I won't be doing it anytime soon.

[discomatt69]

Yes 3.6 would suffice but at over 40k when you can buy a complete and running RR with all the parts for less than 20k just doesn’t add up, what 20k+ for the weeks labour when it just drops straight in

[Cambo_oldjaguar]

All these sorts of problems may also lead to the hope of a 3L V6 Ford Ranger engine being an easy replacement being dashed.
The Land Rover engine mount brackets don't bolt up to the Ranger block, so no, not an easy replacement, perhaps not even with custom mounts/brackets. It's a very different setup.
