    Default 602 and 662 engines.

    Can someone please the me the differences between the 602 and 662 engines, size and power output.
    Can the 602 be replaced by the 662 without major problems in a 2005 Musso?

    Here is a lot of info on the Musso:

    Hope it helps. Seems the 662 had a stock turbo where the 602 did not.

    Here is a photo of the 662. Looks the same size as the 602 to me.

    BTW here is the workshop manual - not sure if it is for the 602 or 662:

    Hello,

    I know this is an old thread, but i thought it best to post my question here, instead of starting a new thread. If this is considered against the forum's rules/ethics, I apologize.


    When (year?) did Musso replace the non-turbo 2.9 with the turbo 2.9 engine? And did both versions run concurrently for a while? I am specifically interested in the answer as it pertains to the Musso Sports (bakkie). I don't know if the switch from non-turbo to turbo happened at the same time for both the SUV and the Double cab.

    I am very confused when looking at old Musso's for sale in the classifieds. And trying to find a definitive answer on google proved unsuccessful.

    Related questions are:

    Was the 602 exclusively a non-turbo, and the 662 exclusively a turbo engine, or are there 602's that came from the factory with turbo's?

    If the 602 was not a factory turbo, was it a popular/easy conversion to put turbos on them, or are the classified advertisers misinformed when they list their 602's as a 2.9DT?

    The reason Im asking all of this is because looking at the prices of the (now 20-odd year old) Musso Sports are very attractive when compared to other brands from the same era, and as a second (or third) vehicle is something I would be able to afford without breaking the bank or needing a loan to acquire. How is parts availability and maintenance cost on these old examples?

    The Musso had the Merc OM602 inline 5. As far as I can see, the turbo version was available from 1997 onwards on the wagon, but no clear indication when the change happened on the Sport.

    It will be obvious which one has a turbo if you look at the engine.

    Body and trim spares are an issue. I reckon some wear and tear items like bushes and bearings might also be a challenge.

    Personally I'm not sure I'd take a chance.

    IIRC the sports came out with the OM662 turbo engine

    Parts availability from Korean parts, KZn or GP relatively good

    It is an older vehicle already if you can swing spanners it will save on costs of maintenance and repairs

    They call the engine in the Ssanyong Stavic and the Rexton the OM 662. Suposed to be the same as the 270 5cyl engines in the MB's.

    But there are quite a couple of differences.

    That is good news. I must admit, i am fairly certain it is the turbo. The owner doesnt know, and due to both work obligations and the lockdown, isnt with the vehicle to take a decent picture of the engine. For the same reasons, I cant take a drive to have a look. All she can tell me is that somewhere she read/heard it is the "intercooler". According to the advert, it is a 2005 model, which would also led me to believe it would be the turbo engine.

    Im glad to hear about parts availability in KZN, as that is where I live. I guess my questions would all be answered once lockdown is lifted, and i can go have a look at the vehicle myself.

    Thank you all for the feedback so far

    An uncle bought a Musso when they first came out. Through the dealership he had a turbo fitted, by Alpine IIRC.

    If anybody is looking for turbo manifolds - I have the manifolds available for the Safari turbo (don't have a turbo, but they are very common).

    Also have an aftermarket intercooler

    And a number of other spares (like oil pump, rubbers etc. fyi)
