Yanmar or Perkins conversion...

[Curt]

Anyone have info/experience or knowledge of putting a small marine diesel in a RR or Disco?

or have I had too much to drink

[SimonArmstrong]

Many many people have put perkins engines into landrovers a very good idea me thinks

[Curt]

Know of any writings on the swap?

[SimonArmstrong]

Dude do a google search, there is a lot of stuff out there im sure!

Conversion plates and mounts etc are widely available, over here atleast...

P.S. love the bouncy smily, my favourite!

I take it you will be swapping it in, in favour of a V8?

Yep, will pull out a V8 and put in the diesel...Was hoping to get some response here instead of having to weed through search engines and hopefully find someone with direct knowledge....and since you liked it so much:

[SimonArmstrong]

I aint done it...yet!

I think a company called millers(??) make the mounts, you could try them?

Its quite a good conversion,however there are a few thing you need to know.
There are 2 common types of perkins engine fitted to landys and rangies,the first one is a perkins 4203(4203 denotes 4 cylinder 203 cubic inches)which is an engine witha metric capacity of 3.3 litres a good strong engine yet a little unerfined will pull a house down but noisy and not for long journeys normally found in series vehicles occasionally in range rovers,the other type is a perkins 4236 of 3.8 liters in my opinion one of the best rangie conversions,the engines are bomb proof very solid and strong they also do a turbo version of this power unit.These engines are common marine engines in th U.S.
The conversion company is called milners but I dont think they are in buisness any longer but secondhand engines with kits can be sourced quite readily.

ONz out.

Have you fellows looked into the V8 GMC Diesels (6.2/6.5l the ones the Hummers are fitted with) we use them in rangies etc a company called samurai do the conversions over here probably more suited to you chaps as availability will be better and engines cheaper.

Cheers Onz

thanks for the tip.... But I do not want the weight of a large V8, plus I have owned a 6.2 and although the parts are available, I'd prob have to buy a bunch of them, my last 6.2 was unreliable, and reliability is why I want to go diesel. The 6.2 was not designed from the ground up as a diesel...I would like a commercial or marine duty engine, in which parts are easily obtained world-wide, in case I take the thing to AU or Alaska...etc.

So everyone pls keep an eye out for any kits or ready made components to assist in the conversion, I would prefer to use a Yanmar, Kubota, Perkins, etc. prob 4 cyl. w/turbo

many thanks for your info though

Couldn't agree with Onslow more. Perkins engines will outlast UHT milk. My Dad had a big 4 in his sailboat, I had a 6-354 in my fishing boat. They are heavy, but tons of low end torque. You will need to evaluate you gearing carfully as they don't rev like your V8.
There's a guy in Fort Lauderdale who has lots of Perkins engines, Auto & Marine of Ft. L His name is Oliver Jones. He also has a bunch of Nissans and Isuzus but I just couldn't bring myself to use one, though I understand Isuzu conversions are pretty popular too, GM and Ford Diesels are too heavy for a Rangie, but properly resprung, I guess OK in a Def.
I looked into the Brazilian International 2.8, alot more torque and HP than a 300Tdi, but lack of spare parts suppliers scared me off. The nice thing about that engine is you can use your ZF gearbox AS-IS.
I ended up scratch building a 4.2 to replace my 3.9 in the Defender. HUGE improvemant, and rechipped, get 25% fuel improvement, though I wish I knew about the good deals on new 4.6 Bosch longblocks

Don't know if this is still a problem but some of the older Perkins Range Rover conversions used to be a real pain to start in cold weather. Might be worth looking into this for that trip to Alaska! Hope they now have glow plugs!

[onslow]

Some of the very old p4 perkins where a pig to start but the 203 and 236 have thermo starts and are rarely used so starting isnt a problem anymore but certainly a valid point.

I am working on a design for a diesel rover set up including a custom trailer/sleeper unit capable of self-sustained living/traveling for 6 or so months. I will soon post a link to the website I am creating for the project and hope everyone will give input/ideas.

For several reasons I have decided to go with a Yanmar Engine...

Look for a link soon

[onslow]

Hi Curt,
I would be very interested in the yanmar conversion,would appreciate any info whilst you are carrying out the conversion.
Cheers Tony

[SimonArmstrong]

Curt, i too would be greatly interested in the yanmar conversion, keep us poseted
