Mercedes 5cyd diesel? - Land Rovers Only

LANDY96 · 02-15-2005, 02:36 PM

Has anyone out there heard or tried to put the 5cyd turbo diesel in a discovery, Defender, RRC.? I have a 83 300d, the more I look at her, the more the engine seduces me,

. I know people have put the 300tdi, 200tdi, 2.8 powerstroke, and sometimes the nissan diesel in. Give me your thoughts. I have a 96 Discovery 5-speed. With a little(lot) of hard work it can be done, I assume. The mercedes diesel is one Heck of a workhorse, easy maintanence too. I just don't know about the bellhousings.

I'm told it can be done.
The ring on the back of the engine just needs to be modified.
I haven't seen one personally but my buddy was checking the same thing for me last Tuesday.

Where can we get a 300tdi to put into a discovery I? How much would that cost? This seems very intriguing, if it is possible and the cost within reason, I wouldnt mind coverting the v-8 to a 300tdi diesel. Does anybody know the performace specs on the 300tdi?

Give Jim Young a call at Sharon Autobody, Sharon CT. He put a 4 cyl MB diesel in his series, and it will have the same bell housing bolt pattern, distances, etc as the 5 cyl. I have heard of the 5 cyl being used in Unimogs (404) with good success, but the engine lays over on about a 15 degree angle.

This Merc 3L Diesel is a popular conversion for Series landys in South Africa.
Guys even put them into Toyota 4x4 trucks!!!

Bellhousings and enjin mounts are available. I will be able to find out from where if somebody is intrested.
I dont know of any dDisco/defender conversions here though.

OkieRover · 02-17-2005, 08:16 AM

Please let us know. I have designs to get one.

LANDY96 · 02-17-2005, 11:38 AM

As long as I can mate the engine to a r380 I am a happy man!!! Please give more info

This could be a inexpensive conversion. I believe I could use parts off a 240d or 300d non turbo 4-speed.(hard to find though). I would like to get a-hold of dead r380 and do some measurements. ANY ONE OUT THERE CLOSE BY HAVE ONE?

Hey doesnt the jeep liberty CRD have a diesel engine? I know its a travesty to put a JEEP engine in a land rover, but it is a diseal right? I only bring this up because of the fact that I remember that the jeep crd was brought up not too long ago in this very forum. I think it would be a great to have that engine, its said to have around 300lbs/ft of torque and about 160hp. The matter of fitting it within a Discovery presents a problem of sorts, but if your willing and commited anything can be done, just as long as you have the green to back it up. What do you gentleman think about such a proposal?

LANDY96 · 02-21-2005, 07:53 AM

Yeah, jeep has a diesel out. That would never work in a Discovery though, without MAJOR modifications. Besides, it is electronicly controled, like the TD5. I want a mechanical injection pump. But as soon as the dealership down here gets one, I want to go drive it.

Hi

I have spoken to two companies that does the 5 cyl Merc enjin conversion into SIII Landys. (Unfortunatly none have web sites)
They do the following:

1) They only use Landys fitted with the 6 Cyl enjins - the normal 4 cyl gearbox apperently cant handle the strain of the Merc 5 cyl enjin!
2) They dont have bellhousings, instead they take the Land Rover bellhousing and a corrisponding Merc bellhousing and do a "cut-and-weld" job to get a bellhousing (apparently cheaper than to have bellhousings specially made up.
3) Enjin mounts is also made up as required.
4) The biggest problem is the clutch assembly! (no standerd soulution there)
- The one company mates the Merc presure plate to the Landy Clutch.
- the other guys use a hybrid that contains the Merc presure plate and all sorts of other parts from Opel (Holden) and Rover.

None has ever converted a Disco or Defender.

My brother Is currently fitting a Merc 602 5cyl 2.9l TurboDiesel to his Forword Control landie I will keep you guys upto date with pictures as he progresses, It seems that this conversion will go in with no problems.

I am in Edmonton, Alberta, Canada area. I am just (having) a 5 Cyl NonTurbo Mercedes Diesel Engine put into a 1967 109, formerly a 6 Cyl NADA model. Vehicle will be on the road shortly. Local mechanic has done several 4 and 5 Cyl conversions. Designed and builds his own conversion ring. Uses a Mercedes/Land Rover Clutch Combination. Email me if you wish (roverwanabe@yahoo.com)

Warthog Jnr · 03-23-2005, 02:24 AM

Got this site address from my brother,(Warthog) it's pretty cool.

I am in the process of preparing a OM 602LA engine to be fitted into my S2A FC.
The engine is a 5cyl 2.9 turbo intercooled Mercedes Benz engine as fitted to Sprinter vans. It puts out 120Hp @ 3800rpm and 280Nm @ 2000rpm.
The unit will at this stage be mounted to the std FC transmission as I don't want to loose the PTO and hydraulic winch.
I will at a later stage fit a standard S2 transmission after modifying/locating a PTO. Another alternative would be to fit the much stronger Santana transmission as installed in the South African built S3"s". (The PTO of the FC differs from the std transmission as the FC has a totaly different transfer box. This results in the mainshafts also being different.)

There are different variants of this engine. Ssang Yong use a 602 which is naturally aspirated and fitted with an inline injector pump whilst the engine I am fitting is turbo charged and originally fitted with an electronically controlled rotary pump.
The first item on the list is to get rid of the electronics so that the pump operates 100% mechanically. Fitting an in-line pump is not an option as the injectors used with a rotary pump require a higher pressure that those fitted when using an in-line pump. There are no mechanical rotary pumps available for this particular engine type, therefore a special injector pump was built using the fuel head and internal components of the original pump. The housings and governor apparently originate on an Iveco injectror pump.
A problem was encountered with the 5cyl cam plate inside the pump but I would at this stage rather not divulge what was done to overcome the problem! What we done most definately will not carry the blessing of the OEM.(Bosch)
The pump did performed faultlessly during it's 2 hour stint on the test bench whilst callibrating. You may ask why 2 hours. The answer is simple - There are no specs for the pump as it is a hybrid and the time taken was to get the Fuel delivery curve identical to that of the electronic pump.

I've gotta run but will continue with some more details later.

this is a dream come true if it works.... i love my diesel mercedes never thought of doin this.. keep me updated

John Karlsson · 09-25-2005, 12:31 PM

Look here <http://www.britrest.com> for 200Tdi, 300Tdi, and 2.8 conversions.

Merc 5cyl. is really strong mottor .

My dad rebuild one for his friend and his friend was stupid and did not broke it in . So he seazed up the mottor. Rods and pistons where seazed . The reason is that he stared to race a nother 300D that was newer. He was faster in his 300d untill it started to seaze up . and this was like day after the mottor was installed . After the second rebuild , my dad told him that he will not rebuild anything for him .

I would not mind sticking that 300D turbo in my Disco . Get some fast glow plugs , like my dad had in his 200D . It tuke only 2 sec. on early winter morning in Poland .

So personaly I would go with the Merc mottor

.

Funrover · 09-26-2005, 01:50 PM

a little unrelated but i have a 71 mercedes 220 diesel that has had a glow plug problem... Once in awhile it burn out two of the four plugs, never the same two.... any ideas?

Kaliman · 02-16-2006, 10:11 PM

Overzised battery?

In the other hand.
I've seen several 2 door Range Rover with the MB 5cyl, Turbo and none.
I think that's the perfect 4x4, the best chasis ever, with the best engine ever.
I want 2 build one for myself.

My english sucks.

Landy96: I am also interested in using the 5 cylinder Mercedes diesel but have to wonder about emissions testing in Texas and my area, B.C. (Canada). What will happen if I turn up at the testing facility with an old sooty diesel powerplant and their computer shows I should have a 4 liter V8 in the vehicle. I almost afraid to ask them....
At the moment, I have an old Willys wagon as well that needs the Mercedes engine far more than my 96 Disco 5spd!

what would the gas miles be like on a disco or RRC (mercedes diesel rebuilt)

appstatedisco · 05-24-2006, 11:08 AM

I'm guessing high 20's, possibly low 30's?

LANDY96 · 05-24-2006, 01:51 PM

OK EVERYONE! I have researched this possibility, and have come to the conclusion, that it would be EXTREMELY difficult, if not near impossible to install a 617a into a Discovery. Just looking at the over-all height and length of the engine, major modifications would have to be made. Starting with the oil pan sump. It sits WAY to low, and the pan does not clear the axle! The engine fan would have to be taken out, and other means of cooling the engine would have to be addressed. If you wanted to keep the A/C, there would be NO way left to cool the engine! The weight of the engine is also another concern. The 617A(turbo diesel 5cyl) Fully dressed weighs near 1000lbs

That is about 300lbs more than the rover V8. Now you are looking at MUCH stronger springs! Don't get me wrong, there are ways to do almost anything!! But I don't have the money or the time to try it. If anyone wants to try it, let me know! I also looked at the amout of time, and money i would sink into this project. I can just buy a Turbo-Diesel G-Wagen for the same price. ....AND get it all!!!
