Diesel conversion feasible in 03 Discovery??
#11
Not my daily driver and what all would I have to part out to get 5 grand? If I could get 5 and then only have to add 5 more I'd definitely do it.
What is the name of the diesel engine that was used in the 03 or 04 discovery's?
Anyone know what I'd gain or lose in terms of hp/torque/speed/weight/efficiency/etc?

Hp you will loose, its about 136hp standard, but EASILY tuneable to 200hp with a stage 2 tune... Torque about same as the V8, but lower down in the range, weight, well not a lot in it tbh. Speed, well its no where near as quick as the V8, but its a 2 ton brick for playing in the mud not flying round the streets, oh yeah.........about 28-32 MPG btw

Not to POP your bubble, but Oh Well,what the Hell, you can't do a conversion on any D2 unless you plan on replacing the t/case and tranny. With an after market engine and now no ECU to run the tranny, you are high and dry, that is why people who do the conversions do them on D1's with no electronic tranny.

And I'm jealous! I haven't told anybody here, but I want to live in the UK one day. I actually started planning it all out last summer. There was a flat in Liverpool I was looking at, I was filling out paperwork for my passport, I had gathered all the required paperwork to apply for my visa...and then the economy went down the crapper. The USD was worth about half of the GBP, I was stuck in my apartment lease for another year, and my plans just sort of fell apart. Maybe I can visit one day, but I have to save up lots of £££ before I can even imagine moving across the pond.
Is that the same Inline-5 I had in my old 300SD?

Theres no diff in the transfer box on Diesels or V8's, so dont see why you cant do it
The Auto box is identical for the 4.0 v8's, and only 15mm longer for the 4.6, buts it operation is the same. So cannot see an issue with that either, although some additional wiring may be needed between the Auto ECU and the Diesel ECM.
if you got the time and money its 100% possible.

Bottom line, unless he wants to gut that truck, a D2 can't be converted , much less get past the state and feds.

My tranny is about done anyway. Previous owner had it running almost dry and it makes a lot of noise.
This weekend I'm going to make some calls and source an engine. Will keep everyone updated on the process.

Tranny is electronic and will not operate off of an aftermarket ECU, If you can't use the tranny, you probably won't be able to use the t/case. As for differences, the tranny has many similiar parts buty is set up for a diesel, the t/cade has a different gearing the one of your Diesels.

the only diff really is the autobox front housing that mounts it to the engine, obviously the TD5 and V8 are different, but behind that, its all the same........Ashcroft transmissions can supply an Auto box with the correct bell housing for a diesel easily, its all down to how big your pocket is.
if you have some specific questions, send Dave Ashcroft an e-mail, Im sure he will help and iron out the facts. http://www.ashcroft-transmissions.co.uk/
On NAS market vehicles from 03 model year, the ZF 4HP24 transmission unit is introduced for use with the 4.6 litre
V8 engine. This transmission is required to accomodate the increased power output of the larger engine. The ZF
4HP22 transmission remains in use on vehicles with Td5 and 4.0 litre V8 engines.
Both transmission units are of similar construction, with the ZF 4HP24 unit being 15 mm longer than the 4HP22 unit
to accomodate a larger fluid pump. The operation of both transmission units is the same.
Engine mountings would be another of the big considerations, but that would be expected with an engine swap.
And as far as the t/case goes, I can find no ref to what Mikes saying..........they are identical imo, but he my be able to show the info ?
KBW, if you go ahead with this, then good for you buddy, I dont see that many issues at all really apart from time + cost, and I can say this, "if" you do it, then it will be the first of many I bet
