This question is for diesel drivers - what is the best engine transplant for my automatic Range Rover? My criteria are: economical, reliable, waterproof engine so I think that means a small diesel. Next it must be quiet and smooth so that rules out Rover and Isuzu. Next it must be fairly small so that rules out the big Toyota and Nissan 6's. Next it must be relatively simple so that rules out any of the new computer controlled engines. I considering on a Nissan SD33 or a Nissan TD27. It is real hard to find a robust discussion on this subject so I would really appreciate the experience you have had with your diesels. TIA

When the engine Bay was insulated properly the 3.9 4BD1 Isuzu on my 110 was very quiet!!!
Add a Turbo and it is even quieter, add this to the fact that it will just bolt straight in ( Depends on what year RR it is ) ,coupled with the bullet proof ness of the engine makes this the best option (IMHO)
I was getting 9km/l in the 110 as for smoothness if you raise the Idle slightly it got rid of all the shaking.

Just experiences & My 2¢

If your RR was petrol and you are going to go diesel, the advice I recieved from Graeme Cooper is that it will be prohibitivly expensive to do the change due to all the ancilliary equipment that needs to change.

I agree.Your heading into uncharted waters .This is maybe the reason you have found little discussion on the subject.
If you went ahead,the easiest way would be to buy the whole front of the Nissan and transfer as much as possible over.That is going to bump it up a bit but much cheaper than running around looking for relays,solenoids, fuel filters ect.
If you really want a diesel ,much better to sell your RR and buy a Nissan/Toyota.
Im guessing,but I reckon your RR would have a higher doller value left as it is.
I found an article in an UK Landrover mag a few years ago .It was about horror RR diesel conversions in the UK.One of the main problems was that diesels that ran smooth in their original body shook the crap out of the range rover .Its not that the RR is an inferior vehicle,its because the vehicle is designed to cope with a particular vibration frequency from the motor and once you step outside it,it becomes unpleasent.

You will never recoup the cost in fuel savings and you WILL miss the V8!

How much $$ are you budgeting for this project?/

TD27 wont be cheap, adn who knows how it will pull a rangie along.
SD33 very old donk, but should be cheap as chips..

Theres numerous SMALL diesels around but all depends on $$ you wanna spend, and the issues of getting it registered and insured.

What do you want the truck for? Touring, or weekend warrior??

I love the answers so far. I know the project does not make much economic sense but I love tinkering. In the future I suppose long range touring will be my main use but it is currently my daily driver.

Think again, if you go for a small less powerful donk you will lose the economy advantage of the diesel..

You say a big 6 wont fit in there like a TD42 or 1 HDT E or what ever the Yota thing is?

I'll vouch for the SD33-T (thats turbo diesel). I think they are more powerful than the TD27 by a wisker. 88kW? and 280Nm? of torque I think. Usable rev range is between 1 to 2000rpm, not much point going past 2500rpm power wise. Like one of the previous posts said, the SD33 has been around for a while so they are readily available and cheap as chips to buy (recondition, like any diesel, is another matter!).

Pulls like a trojan in my patrol (recently towed a rangie on a car trailer ~2.5ton no worries - except for my old worn out rear leaf springs). Fuel Economy is excellent - about 10L per 100km around town (still with 380,000km on the clock). Gearing is okay for the highway - about 2600rpm at 110kph - I think a set of 33's would knock that down to a nicer level.

Only thing to remember is that its a diesel so don't expect to go anywhere fast. Its a truck engine designed for long life. I dare say it might go a lot better behind a ZF 4spd auto as you get to 5th gear in the patrol by about 50kph - so the (hopefully) taller gears of the auto might suit it more.

Only thing to keep in mind when doing a conversion like this i think is the stall rate of the torque converter. I think due to the rev range of the SD33, unless you change the lock point in the torque converter it will wont lock up under normal driving conditions (i dont think - something to check out with a trans specialist).

Can I ask why you are going a diesel over the 3.5L? I'm seriously considering a change from my MK patrol to a ~85 model rangie myself (i want nice soft coil springs over my old harsh leafs).

hope this helps,
good luck with it.

Forgot to add - you realise the SD33 is a staight 6 cyl where as the TD27 is (i think) a 4 cyl? Being a straight six the SD is nice and smooth, but would it fit in the rangie? Rangies don't exactly have the longest bonnet in the world.

Got a mate like you. he bought a landie with a 318 with rangerover disc diffs as an unfinished project. It needed to have the disc brake diffs fitted to be registered to He couldnt fit the diffs so he bought a turbocharged 245 coz being a 6 it could be registered as is. But the 245 was to long and wouldnt fit. Finally I talked him into putting a 186 into it coz he had the motor and all the gear to do this conversion. So he tried getting the 318 going out of the vehicle to show it ran when he sold it. It backfired and lit up the large amount of hay bales stored in the shed and torched the lot! I also have mates that have put 245s into hg holdens and 161s into toyota lite stouts. Good luck and keep on tinkering it is obviosly your passion

The wreckers get offers of vehicles very cheap that have been modified. The petrol to diesel conversion is very dificult because the gear ratios are so diferent. A rangie neads a change of diffs to get any sort of resonable cruising speed. The vibration and niose is realy bad in a rangie because the floor is not thick steel like a jap machine. My sugestion would be to sell it and get a disco, early diesels are under $20k now.

Sounds good but which engine is that? There is a firm does adaptor kits for the 4m40 engine but I thought it had a belt drive OHC? Please feel free to contact me off list.

Sorry, only new to this forum and couldn't figure out where to get your email addy.

yeah It's the 4M40. yeah no nice plastic belt cover on the front of my motor. mechanical injection too :)
was probably what really swayed me to get this model in the end. I'm not a big fan of belts and electronics in the bush if it can be avoided.
I haven't got a manual for it yet, so I dont have much more info, and I haven't really worked on these motors much.

If you want some pics of it to help the tinkering thought process :) just tell me what of and your email.
mine is robm999 at tpg com au
