Merc OM602 Engine into a SFA?

[krazy_kameleon]

I love the 5 cyl OM602 engine (used in Sprinter amongst many others)
has anyone ever put one of these into a 'Lux before?

excerpt from Wikipedia:
"The successor of the OM617 engine family was the newly developed straight-5 Diesel automobile engine OM602 from Mercedes-Benz used from 1980s up to 2002. With some Mercedes-Benz 250D/E250D diesels exceeding 500,000 or 1,000,000 miles, it's considered to be the one of the most reliable engines ever produced, a success which is only comparable with the famous OM617 engine"

If the straight six of the Supra fits then dimensionally I cant see why the 5pot wouldn't fit.

I was looking at fitting the mechanical version to replace my 3C-T

any comments? or suggestions?

from the number of views, I can see this is of some interest but the lack of replies points to 2 options:

1. this is a great new idea that nobody has tried
2. nobody has tried this because its a *a* idea

hmmm, I wonder...

[Bijl]

I think its a great idea!
But you will be the first therefore not many guys who will be able to help with the convertion.
How difficult can it get? Belhousing, radiator and engine mounts?

Wrong... ECU needed to control the turbo boost and also the diesel pump is electronic. Personally... You buy a merc you pay in 1000's to fix anything on it.Also remember that the engine might be cheap but I can tell you now, that those engines need to be 100% sound or you will look like a LR with constant break downs.

I have spoken to a few fleet owners that runs both the SPrinters and Iveco's, and the Iveco beats the Merc to running costs and much more durable to abuse and much more reliable than the Mercs. Mercs are finiky vehicle's but notetheless a great drive.

Rather go for the KZTE route in your SFA as it has been done before and yes you can get the ecu and things also loose for the KZTE. Or if you feel like spalshing out, do a 3.0 D4D conversion on your SFA.

[krazy_kameleon]

Thanks for the input Johan,

The version that I am looking at is fully mechanical. Dont want ECU's so the D4D is out of the question. also some have problematic injectors when bad fuel is used. I can run my 3C on SVO!
I currently run a 3C-T and the KZTE with mechanical pump conversion puts out the same power as my 3C with worse fuel consumption. Hence the Merc idea. and 5cyl can only be cool.

Not fixed on the idea yet, thats why I posted on the forum - to get others ideas on it

Thanks for the feedback everyone

[krazy_kameleon]

anymore comments or opions on this, ...anyone?

[Polarbear2008]

If you are looking for reliability, why then not the Ford Transit engine as used in the LR Puma?

They are used in Europe in a similar setup to the Iveco, and it seems that they are unbreakable. From what I understand, it is also a fairly simple engine without too much bells and whistles.....

Just a thought...

[kfxnando]

again any thing is possible!!

as for those motors, and here we differ as me referring to the ones in the sprinters!! presume the ones with the ECUs!!

the one company that we contract to has a whole fleet of them!!
and they get abused!! and I do mean abused!! and the motors do hold out pretty well!!

am not an expert, however though that the Ivico was the same motor as the Merc one!! again me not an expert!!
or is that they cross fit!!

then on the conversion!!
its the usual story!!
as you will be the 1st one to try it, could be a little more difficult to get help, however there are many on here who have done conversions of all types!!

can it be done!!! IMO!! yes!!
could be a great conversion, and you could be the 1st of many!!

as for the cost of spares its like any thing else!! once you start with a specific make,there will always be people telling you that its expensive!! however once you dig deeper one will almost always find a cheaper alternative for spares!! from Toyota to Ford to Jeep to Korean vehicles!!

hope you have lots of fun!! enjoy!!

[conversion man]

Rather go for aBT 4 CUMMINS if you want to spend that much effort and money on a DIESEL

[Polarbear2008]

BTW

The 602 engine is the same one that is fitted to all the Ssangyong Musso/Korandos that were initially brought to our shores. +/- 70Kw normally aspirated, mechanical diesel pump.

Only later did they replace it with the 662 that had turbo charging as standard. - I have a link for the service manual/specs for the 662 if you are interested.

There are differences seeing that the SSangyong engine was built "under Licenese" and in RSA Merc will not even try and support you with parts for the SS derivative.....

[zepplin]

Why not just get the 4x4 Sprinter or Iveco?

[Klong se Pa]

Go for it Rick!!

Have you got the motor allready, and if so, from which donor-vehicle did you get it? Is it n/a or turboed? From your other thread (Rokarok gets a makeover), I made the assumption that you are quite clued-up with these engines, and will know if it is sound or not, and if it do has problems, will be able to sort it yourself.

Yes, such a once off can be a headache, but if the owner has the skills, knowhow and time (money?) to sort things out himself, then why not? As long as it doesn't cost you an arm and a leg, you would have quite an unique vehicle, therefore I would think the joy of the project will be so much more rewarding. I for one would love to have a diesel Merc-powered 'Lux, cause I grew up with 220D, 240D and 300D's. Man oh man, the sound of that 5-pot! Dad had a 1981 300D with Alpine-turbo, lend it to me (after I first had to wash and wax it) when I started vry-ing in the drive-inn era still. Imagine.......!!

Would like to book the first drive with the OM, Rick. Strongs, keep us posted plz!

[krazy_kameleon]

I havn't got the motor yet but I will be looking for the 300D version with factory turbo set-up. They are tunable to 145HP with just IP optimisation.

Still recovering budget wise from the body overhaul.

But will keep all posted as to when I will be starting

[PERS KERS]

Hoekom wil julle down grade na n diesel enjin toe ? jy wil nie die Hilux nog stadiger maak nie?

[curre]

Baie interresante ombouing, maar ek dink jou betroubaarheid gaan by die deur uitvlieg.
Nietemin hou ons op hoogte.

[krazy_kameleon]

Already got a 3C diesel installed - I recon the OM602 would be an upgrade on the 3C but time will tell...
some financial considerations have delayed this conversion so I am stuck with the 3C for the time being.

[doppies]

Hi, ekself het ook die moontlikhede oorweeg, maar daar is 'n paar negtiewe kante.Die kraglewering van die std 602 soos in die SSang young is feitlik identies aan die Toy 5 L.'n Kompleet herbouing kos tussen 50-60 K. 'n Nuwe sump moet gebou word.Die oorspronklike is van alminuim met 'n dwars uitbouing wat in die weg van die voorste dryfas is. Die fan is off centre en druk teen die stuurkas. Die masjin is feitlik net so lank as die 3.0 cressida wat dinge bemoeilik. Die olie filter is agter links teen die masjin wat ook verskuif moet word. Dan moet jy nog 'n belhousing
ontwerp, want dit is nerens verkrygbaar nie. Niks is onmoontlik nie, maar vir al die effort met feitlik geen verbetering in kraglewering en soos genoem die hoe koste aan herbouing maak dit nie die moeite werd nie. Die ouens vervang juis die masjine met die Mazda 2.5 td weens die hoe herstelkoste van die 602

[Hoppy]

Die merc enjins is goed tot jy parte nodig het, dis onbetaalbaar duur.
Die WL enjin is n beter opsie en sy kragkurwe pas perfek by die SFA se ratverhouding, hy is korter en ligter as n 5L en sy komponente sit aan die regte kante. Hy is ook goedkoop om te koop en te herstel en parte is vrylik beskikbaar.

[Kaspaas]

Rick,

So n omboung is al gedoen. Nie seker oor watse enjin dit is nie, maar defenief nie net 70kw nie!!!!!
In Kakamas is n SFA met n 5cyl Merc enjin in en 35 duim tyers. Groot "King of The Dunes" sticker agter op!
Ek ken die oom baie goed, as jy wil drop my n PM dan stuur ek jou sy nommer.

[jacques kotze]

Ek het so twee weke gelede my Skoonpa se Kia K2700i met n lexus enjin gevat vir n diens by die ou wat die conversion gedoen het. Daar staan 5 Merc Sprinters wat die enjins vervang gaan word met die Lexus, weet nie of dit dieselfde Merc enjins is as die wat julle van praat nie. My gedagte is maar net, as hulle die Merc enjins ruil vir Lexus enjins dan kan daai Merc enjins nie te goedkoop wees om reg te maak nie.

Yes they are basically the same - the Sprinter uses an electronically controlled Injection pump though and if you want to avoid the use of control units (like I do) then you need to city the mechanical pump off of the older w123 Mercedes or early Ssang Yong.

The guys in Germany and Scandinavia get these motors to push out over 450Hp and 650Nm! the motor is good for 75Hp per cylinder without upgrading internals (Pump tuning and element/fuel upgrades only)

[4thGeer]

Hi I have a sfa lux busy with my convertion at the moment fitting a 5cylinder merc motor

[Baby Cruiser]

Hallo 4thgeer. Dis al 'n tydjie na jou laaste post. Het julle toe die 602 ingebou. Wou ook baie graag een insit maar kon net nie een kry nie. Toe maar die ingevoerde 2LII reg gemaak en terug gesit. Ek het nog die idee in my agterkop gebêre. Sal graag wil hoor wat julle toe gedoen het en hoe hy vaar. Brandstof gebruik en ek glo hy sal lekker trek en klim. Hoor graag van jou.

[FIRSTGEER]

Hi there guys.I have been helping my son (4 th Geer) on the forum,to install a 300 d merc 5cyl engine into his sfa which originally had a 4y engine.

Yesterday we started the vehicle and he drove the sfa up and down the road to check the clutch and other issues and I am proud and happy to state that it is RUNNER.

My eldest son (third Geer) has completely stripped and rebuild the body and reprayed the cab and other body components.The roof lining and the mats have also been renewed.

We are now at an assembly stage and the project should be completed by the end of OCTOBER 2017.

We have taken many fotos of the project since the first day when we removed the origonal engine and started striping the hilux. I will humbly aproach Muddog (Andy) for his talented assistance to edit and load our pics and our rebuild story once the project has been completed to enable us to post this rebuild..

WATCH this space.

[Mars]

Congratulations. I can't wait to see the thread.

[Baby Cruiser]

Glad to hear that it is running already. Looking forward to see what you guys have done.
