why not just buy a D1 300tdi auto for around $5k-$7k and save $15k+ on conversion costs (if an auto is planned)??
- and you'll have a smoother quieter motor car that will go just as well

Well,
LR parts and engines are very expensive here and also difficult to find.
Isuzu is cheaper and I can find all parts

Hi Avoon;
What engine do you currently have ? I'm assuming you have the V8 Efi ? if you already have the 300tdi engine IMHO leave it as is , they are a brilliant engine. and you can make them go much better by adjusting the pump plunger and tweaking the pump :twisted:
Edit: What's your Location ?

Where are you, and which models of Isuzu do you have there?

4BD1-T
Irrespective of what engine/transmission you chose, you need to be clear in you mind what it's going to be used for? (if it's a daily driver, can i live with it on a daily basis??), whats your budget (the real budget, not the one you tell the wife:D, and then engineering, rego and insurance questions...
I did all that and am converting my '91 V8 Disco to 4BD1-T/Isuzu transmission. In a nutshell it's not that hard - engine mounts, transfer case adaptor and adaptor shaft, body lift (i don't like them but i have no option), exhaust and the fiddly bits. I'm at the engine mount stage - everything else is in boxes waiting for days off. It's taken me over 2 years to save the money and find all the bits (including '96 Defender front and rear diffs). I understand the 4BD1-t is Euro 1 compliant which means it can be in chassis' up to Jan 1993.
Also, I'm a tightwad and am doing it all myself - I've built a few street car conversions so I know what to do, as well has having a rapport with an engineering signatory.
That's my 2 cents with a 4BD1-T, but do a search and see what the other guys have done with 110's and Rangies - pretty much the same chassis.
The Isuzu 4jb1 (and turbo) is another option....
I think the auto needed to survive behind a 4BD1-t would be big and expensive.
Fffffffffffffank you,
Matt.

If you want to keep it Auto then forget about it, if you think it will be a cheap conversion then think again as it wont unless you can use the Isuzu box and adapt the LR transfer case which would make it a little cheaper.
The V8 box wont take a diesel (as far as I have read on here and other sites) and I dont know of any auto other than an Allison which would cope with a 4bd1.

HI there Iam in Suriname a country on top of Brasil you may think where the hell is that. but it is a very nice country for offroading and you are welcome to visit. Suriname - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Suriname) SDSR07 (http://www.sarkonline.com/images/SR/2007/sdsr07.htm)
We get allot of japanese used cars here and I think I can find any isuzu engine here for about $2000.00
Reading your replies I really don't know what to do yet.
My disco is a 1995 300tdi we only have one dealer here and the delivery time for parts sometimes take up to 2 months.
First I had problems with the timing you know so I made the modifications to get rid of that problem, than my waterpump was dead after that my powersteering pump and now my alternator. Only I found a used alternator and that one was gone within 2 weeks the shaft get thinner inthe back bearing some one told me now I need to change the tensioner before by a new alternator.
Well If it was a japanese car all those parts would be easy to find that is why I am thinking about the swap Since I think my disco needs to be overhauled in lets say 2 years.
So any suggestion that will keep my disco alive is welcome.
Thank you

DOUGAL has suggested an interesting idea when it comes to making autos last longer behind an Isuzu.
Add weight to the flywheel to reduce the harshness of the torque pulses (is that the right term) coming from the engine.
I would love to try an auto/Isuzu, but I'd be reluctant to spend the time and money on something that has not yet been proven as a lasting combination.

I will second that.
i have driven a toymotor 2.4 diesel auto ( only auto in the company) it would run around the manuals. same with a diesel supercharged auto mazda. quite good compared to the manual version of the same

In your location the Isuzu 4JB1T should be able to be found. Used in small Isuzu pickups, it's 2.8 litre turbo.
Adapter kits exist to fit this one into landrovers and it won't kill your autobox like the bigger 4BD1T will.
How common is the HS2.8 where you are? It's related to your 300tdi and parts for that should be easy to find from Brazil.

I think it should be possible to find a HS2.8 do you know where to find a kit or can I make it myself?
Someone also told me I can use a daihatsu DG 2.5 engine do you think that will work is there a kit for that also is 2.5 without a turbo not to weak?
Thank you

avoorn, I have looked at the wiki ref and your country does look very interesting from many points of view but you obviously share the probelms of remoteness from service & spares that some LR owners feel in Australia.
I think you already have the basis of the best engione/gearbox combination in your existing vehicle
Can you work on it yourself? - if so you can get a lot of advice/help from experienced people on this site
Also, a lot of people here find that ordering parts from the UK direct works for them both economically and timewise - surely you could try that...
I sure that we don't have to remind you to keep the servicing (oil/filters etc) current and don't let the timing belt go too long before changes (60k-70k kms) and don't overtighten the new one when installing.
Plenty of 300tdi autos here have travelled over 250k kms and are still going well. You possibly have the most comfortable/practical land rover ever built - my advice would be to stick with it and prepare it well.
regards - Laurie

The HS may be close to a bolt in. It is essentially a redesign of your current engine.
I would avoid the daihatsu, especially being non-turbo.

When I was in Central America, I saw LOTS of GMC 4000 trucks - do you have them in Suriname as well?
https://www.aulro.com/afvb/images/imported/2008/11/59.jpg
These have a 4BD1(T). 3.9L 4cyl that was factory fitted to 110s in Australia. However finding adaptor plates is difficult - even here.

I think I can find this engine if the were factory do you have a factory plant over there? for this engine do I only need the adaptor plate?
Does someone have a picture or specs of this plate?

Have a read here:
http://www.aulro.com/afvb/isuzu-landy-enthusiasts-section/55113-county-v8-4bd1turbo-conversion.html
There is no plant here, the engines were made in Japan (by ISUZU). Land Rover Australia (actually Jaguar Rover Australia back then) did a deal with Isuzu. They were fitted to new 109s and 110s from 1982 to 1990.
I imagine that labour is very cheap where you are? The adaptor is hard to find second hand, and not available new any more. It would probably be easiest/cheapest to get one made.

Indeed I could easily make one over here I only need the specs or an example (picture) so the people here know what to make.
does any one have this information?
Will this work with my AT gearbox???
Thank you

The adaptor referred to is not the sort of thing anyone would make for a one only conversion - Land Rover had to made hundreds of these vehicles.
It consisted of a new flywheel housing to replace the Isuzu housing and new bell housings to replace the LT95 and LT85 bell housings. They changed other things as well.
You might like to look at the isuzu diesel swapper site (http://www.isuzudieselswapper.com) this company is in the USA where many of the isuzu trucks have either auto transmissions, or 5 speed manuals that aren't liked because they don't have an o/d top gear.
