6.2L diesel in P38?

[paradigm]

Has anyone done it , yet?
what are your thoughts?

[p38arover]

I think a front clip from a diesel P38 out of the UK might be a better idea.

I hear ya...
but they are very pricey... 6.2L diesel are plentiful and parts are cheap.
you can even turbo them with very little money
how much do you think shipping a UK clip would cost apart from the initial purchase?

[Casper]

I'm more inclined to thinking that dropping the whole Chevy suburban or H1 hummer on top of a P38 then driving away in the suburban/hummer would be the more sensible and reliable way to go......

Thats just my opinion.

I would like to see someone do it though, then change all the drive train and electricals to make it reliable.

Should be able to have a good car for a bit under $150k ;)

I have often thought that a LS1/2/3 etc with the matching trans would be a good conversion for a P38 which would be relatively reasonably priced.

Cheers Casper

[paradigm]

why so much money? do you want to build ten of these? lol
but seriously... were talking 5 grand max to do a spectacular vehicle

[rovercare]

6.2 ick, been there, rid of it

Dude on stalkbook is doing just that, he's in the us also

I'll be putting a gen 3 and auto in, in the coming few months

[paradigm]

I am going to pair the 6.2 with a t56 six speed manual.

Mine was to an lt77 in a classic, unless your planning on turbocharging it, I wouldn't

Becm can be switched to manual

[33chinacars]

To me this would be the ideal coversion for a P38. Not cheap tho

Hi Gary
I've read about that conversion already... cool car.
It just won't help me much as I have a 6.2L diesel already and that engine is a lot simpler to deal with...
also, parts can be bought anywhere and I can run a large variety of fuel in it.

cool link , but it is not very useful to me.

I need to know what gives the signal to the ECU that the engine is running
and what gives the signal for the transmission to shift.

And this is where it gets expensive.

Good luck mate.

Sorry cant help you with who talks to what & how. Good luck and keep us posted

Ask rovercare, he's onto it, pretty much nutted it all out.:)

[Hoges]

It is not simply a matter of a "signal" to prompt the auto to shift. Said signal also causes the petrol engine to momentarily reduce its torque output (by electronically retarding the ignition timing) so that there's less force on the auto while it swaps from one cog to another.

I am not sufficiently familiar with diesel engines to advise on how this (torque reduction) is accomplished...I'm assuming it's to do with the injection timing...but you'll need to get some expert advice on it
good luck!

BTW what's the weight difference between a 6.2L diesel and the Rover aluminium V8?

[paradigm]

The 6.2L weighs 700lbs dressed.

[Hoges]

The 6.2L weighs 700lbs dressed.

I'd guess you have therefore about an extra 250-300lb in the front end to consider...

And work it does! I was playing around low range starts, full throttle, it works very well

absolutely (:
In my case I have a 3 inch EMU lift and the front sits slightly higher than the rear...that should fix that

I'd speculate that Paradigm and the RocketScience guy on fleecebook are the same person.

They both seem to be going down the same path, and they are both in the USA... what's the chances of two people in the USA owning a P38 and wanting to do a 6.2L diesel conversion?...:p

He may know me by me by my real name on fleecebook as I was the admin that added him to the group.

Cheers, Paul.

Haha, Hi Paul... yes that's me on fleecebook.
I am getting a bit closer... still lots of stuff to read through, the mechanics are only half the part.

Pity those Chev diesels are such unreliable gutless pieces of scrap iron.... :angel:

Nup! They're alloy :p

I understand where you're coming from.
The 6.2L isn't bad , if it's maintained and there are plenty aftermarket parts available, to make the engine more reliable in it's weak spots. Can't say that about the 4.6L.
Then the parts are a lot cheaper and any autostore carries them... can't say that about Land Rover. ( I had to wait a week for a common gasket to arrive @ Land Rover).
Gas mileage is going to be up to 25mpg can add a turbo later.
And I can run all sorts of fuels in it.

Hi,

A french owner from a land rover board in France did the conversion to the hummer engine years ago.

He started with a 2,5 manual P38 and wired it in using most of the OEM sensors.

Had him on the phone to share details and didn't look very difficult to do it from the electronic point of view...

Here's a photo of that work.

That guy was pleased with the performance, economy and reliability of that one...

I still think about it for a 2nd P38 to go expedition for no fuel money (hummer engine can run on drained oil ;))

[paradigm]

great info there... Do you know more what your friend had to do in order to make it work? ...she fit's nicely in the engine bay... I am pleased to see that.
did he use the stock drive shafts or had to use custom made ones?
how about the fan? I can't see much from this camera angle... do you maybe have more photo's?
thank you

Given that there are 280,000,000 yanks, many times more RR's sold there than here, and that GM 6.2 diesel are plentiful and cheap there, I would say there are probably quite a few more than two people in the USA contemplating this conversion.

[Keithy P38]

The two conversions I'd do if/when my engine kicks the bucket, gm 6.5 or ls3 and 6spd auto... I'd be happier with the diesel but won't be disappointed by either!

IIRC there was a lot of work as for any conversion done to the exhaust and the engine mounts

Sorry, no more photos.

[idi traveller]

The first year of the 6.5 had a mechanical injection pump and would make the best of both worlds, no computer/no opacity censor. You can use diesel to waste motor oil for fuel just like the 6.2. But if you can get a surplus military 6.2, it has more metal than the civilian model. The easy part on the tranny would be put a built 700R4 behind it, again no electronics. And lots of transfer case options.

looks as if nothing had happened...

first time starting my 1997 P38 with 6.2l diesel
the exhaust are not yet done , so she's a little loud, but runs perfect.

Have to admit tho ... My sound card ... It sounded as tho you had a mob of "Daffy Ducks" running under the hood .. :p

6.2L wow! pardon my ignorance but what's the gaping hole the previous post photo with the two protruding vertical screw threads?

you do it by clipping the wires and never worry about them again:)

[Davehoos]

does any one have any pictures of the perentie V8 diesel.

they designed sump manufolds etc for it to fit the 6X6.
I saw a UK site that had exhaust manifolds that looked identical to fit a clasic.

Clipping the wires????:eek: Are you saying you let the ECM working for nothing...?

BTW, great work !!! Can't wait for your test drive vids:cool:

[jakeslouw]

That engine would look just great in my 110.

[Keithy P38]

Jake,

My old man has one of them in his 110! You wouldn't believe it if I told you, but the thing (with 4L60E) idles along and makes any form of hard work look like it was easy even with 1500kg of camper trailer behind it!

Get an auto for it though, he killed the original box very quickly!

[banarcus]

Great work on your P38 paradigm. What did you use for a gearbox/transfer case?

Well, I've had the snip, so I'd be tempted to give a testicle for the privilege.... :o

The 4L60E/THM700 is very scarce over here. So is the engine.

What else could I use?

thank you for the compliment banarcus
I used the stock transmission, transfercase and driveshafts.
made some adaptor plates and concentric rings. was very easy

AC is disabled... for now. but the fan works fine

AC is disabled... for now. but the fan works fine

That's the largest issue I've found to overcome, just have to recreation some signals to the becm, as it's relayed from the engine ecu which you don't use

No messages about the auto?

[paradigm]

no message about the auto... it's working with a stand alone computer :)

Becm switched to manual?
