V8 to diesel

[disco-v8]

ok after a realy crappy day of off roading today in my V8 i think i might want to change it to a diesel, not 100% sure yet, but im getting a few electric problems with mine at the mo, so might be easyer to swap the engine!!!!


basicaly what is needed to swap it from a V8 to a diesel 200 or 300TDI????


and please please dont say the realy obverse stuff!!!!!!


mines a 3.9 auto ( zf4 hp auto) so will the diesel engine but up ok????

and what about all the electics in mine will alot of the none engine stuff still work or wont it????

adam, you'll be better off posting this up on www.lr4x4.co.uk
what engine are you intending on if you do go down this last resort route ?
200 or 300 ?
engine mounts will require changine, different rads ect ect
wireing wise, you only need one wire to start the old 200's  :lol:
that wire on petrols goes to the coil to power it up
but i dont no about yours as its efi, maybe it still has a coil :oops:   :oops:
dont do v8's only dervs as you can see  :lol:  :lol:
afink the tdis used the ZF 4HP22 auto box's.....but thats only of top of my head  :?
now i doubt the tdi's will but straight upto the housing as the stud pattern is bound to be different  :roll: , but if you can find a tdi auto box and use that housing, then jobs a gud un i guess  :?

dont give up just yet on the old girl though, ino how much you love the sound  :lol:

Best of both worlds.

Seriously though, most electrical issues can be dealt with, you sure its the right thing?

god no its not the rite thing!!!!!! but everything i do to it just doesnt work, ive tryed my damb hardest to make the old girl water proof, but everything i have sorted out the water will find something else, plus the fueling is all messed up at the mo and doesnt want to idle properly

[Evilgoat]

Well before you do. I've had comments from several people about the punishment the Suzuki will take, normally along the lines of 'Is that a Deisel?'

In the case of the Suzuki it was a case of being methodical about it. High tem greast on the plug lead ends, same again on the coil lead too. Coil gained a boot from a BMW coil (again greased) and the LT system cleaned and all gaskets greased on the connectors. Same on the Dizzy gasket and the breather for the dizzy cap extended.

I can understand your frustration, but stick with the V8 if ya can, obviiously not sure exactly what you have tried so far, but petrol/V8 engines can be quite good in water,  I simply put a marigold ( or similar) glove over the coil and sealed both ends, also a very thin layer of silicon grease around the sealing part of the dizzy cap, Also i strongly recomend good quality ht leads cap ect,  not sure about ya rough running problem but im sure someone will come along shortly to assist,
   


   Keep the V8 dream alive



    Must admit i have been tempted to stick a diesel in mine, but as i dont use it every day i worked out the cost of the work against the amount of fuel i could buy with the same money,  Also sound great and lovely to drive,

   Not knocking diesels just horses for courses  :lol:

Your best bet will be to buy an MOT failure or crash damaged TDi then.

Rad is different
engine mounts are different
gearbox is different
props might both be different because of the gearbox )not sure but mine don't fit Tim's)
Exhaust obviously
On the 300TDi the gearbox crossmember
the wiring loom (glowplugs etc etc) especially if you want A/C

[disco-v8]

ok been doing alittle thinking about this conversion and what differencies are there between my V8 auto and the 300TDI auto????

all i can think of is that there exsactly the same box as they are both zh4 hp22 so the only differerence i can think of is that the bell housing is different, so wont it be easyer just to change the bell housing over????

or is there more to it

[Staffy]

Nooooooooo, ya can't do that.

If you want to bring it down we can have a look and bounch some ideas around about water proofing it. Mine so far (touch wood) has been ok. In the floods etc we had water over the bonnet a couple of times in Astbury.

I have a 3.9 here which runs fine and I am breaking soon, so you are welcome to switch some bits over to find out what the idling problem is then at least you will know what you need to get to put it right. I around most days as I work from home so just let me know.

Water proofing is going to be a process of elimination and could take a while to get it completely right I would have thought. A lot of people on here have done pretty much what a diesel can do in water with their V8's.
It of course is up to you but a bit drastic that and I am pretty sure you'll miss that rumble :)

sorry phil but looks like ill still be going down the derv route.... i love the engine dont get me wrong but too many little niggly things have pushed me away from it

1 fuel cost 5.2 MPG on a fun day just wears thin after a while
2 i hate trying to sort out electrics
3 cooling issues
4 so hard to keep it water proof
5 idling problems

ok 1 or 2 of these problems where ok to live with but they r all an issue now and i just give up, id prefer a cheap running derv :?

not even the lovley rumble will pull me out of this one....


if you wanna try and have a look at it its all urs untill the end of the month then its off the road due to the lack of road tax, i work nites so am free untill 4pm every day

Easier in the long run to buy another one. Not worth the hassle to swap it over.

sorry would have to totaly disagree with you on that one

if i bought another disco i would have to repair weld and fix everything that i have had to do with mine, ive got that much off road gear on mine that it would take agies to swop it all over not much of mine is left in standard form, and i know every little bit of mine to every nut and bolt....

plus who else has got 5mm box section rock sliders replacing there origanal sills, i dont fancy doing that job again!!!!


also i love landrover dont want to scrap one just for the engine...


is it the time of year or something, everybody seem very negative!!!!

valve block is different along with the change points

[Thrasher]

Not negative, just realistic. For the price of an engine you can buy another D1. Then you can slowly migrate all the bits over etc .

The other choice is a lot of engine work, it will most likely have to be inspected by engineers afterwards so you can insure it (age of the vehicle - it's not like it's a series motor...), and lots of other fun pitfalls.

Oh and a non-EDC 300tdi Auto ..... ick. Not a good combination. I'd go manual if I was retro-fitting a tractor engine ;-)

[muddyjames]

there is a disco 2.5tdi engine for sale here on MC

[Range Rover Blues]

I've driven a couple of 300TDi autos, RRR has one now and I think they're really nice.

BUT, Xtrtemeteam is right, you cannot use a V* box on a TDi lump, it just won't work properly and I suspect you'll quickly be looking for a new engine if you do.

[Thrasher]

The 300Tdi auto, pre-EDC was always gutless, got low mpg and never got good reviews. That's why they eventually gave in and added EDC and bumped the output of the engine up as well.
