    Question Isuzu KB 280 TD turbo & intercooler question

    Can someone tell me how much it will cost to replace the turbo on a 1999 or 2000 or 2001 KB 280 td?

    Most people I spoke to said that the turbo is the only real weak spot on these bakkies if driven the wrong way.

    My question stemm from the idea to maby, hopefulle be able to buy a vehicle at the end of this year. My sights are set on one of these Isuzus.
    But I am worried that the turbo goes just after I buy it.

    Also, I read people build intercoolers into them, does it make a noticable differance and hoe much does THAT cost?

    Make sure Sakkie responds to your post.
    I'd rather believe him than anybody else, when it comes to Isuzus.

    My 280DT had done 330 000+ kms without one engine hiccup when I sold it.

    Look for a nice Frontier Granny-wagon!

    They are vrilliant vehicles.

    New Turbo, R16 - R20K, just fitted intercooler to my Frontier, R11K + R6700 for overhaul of diesel pump and fitment of new wastegate. Previous diesel "fundi" bent some arm in the wastegate resulting in it having to be replaced.

    Mileage now 200 000km.

    Love my Granny Wagon, don't like the name given to by certain persons! LOL!!!

    The turbo's on the 280DT lasts!! Yes, a few of them have given up the ghost but that was mostly due to "experts" fiddling with them. If looked after, and I mean in general - not excessive TLC etc, they will last 400 000 k's easily. If you were to buy a replacement turbo from the stealers you will easily pay the sort of amount s as mentioned above. Nowadays there are plenty other reliable sources for replacement turbo's at half the price.

    Intercooler on a 280DT engine makes a difference, for sure. And the difference is positive, and it can aid in the reliability of the engine as well as cooler air now enters the engine. Heat is the nemesis of any diesel engine. Prices vary from supplier to supplier. There is an Isuzu specialist by the name of Mario Fourie in the Cape. You will find him on www.isuzuoffroad.co.za He also does the i/c conversions and he KNOWS his stuff around an Isuzu

    Stockman, don't blame that Grannyvan name on Sakkie It actually has another source

    btw, Me thinks Sakkie is only returning to the RSA this coming weekend, so we will have to wait a few days longer for his replies.

    JD, Ek dink die punt is dat indien jy 'n skoon bakkie koop en hom reg onderhou sal hy nie probleme gee nie.

    Daar is letterlik hordes 280's wat in die Transkei rondloop, hulle rook nie en as hy nie daar breek nie......

    You'll know long before a turbo "goes" that it's on it's way - oil leaks from centre housings, oil in plumbing (do not confuse with oil from breather) and noise (loud whirring or scraping). Easiest to check by removing intake hose and feel for any side play or excessive up/down play - to the extent that it touches the housing. No touch, should be o/k.
    Provided you allow some cooling down time (such as slowing down on highway before exiting or idling 1 or 2 mins after pushing in town your turbo will last for many years. Biggest turbo killers are overspeed / overboost (fiddling with wastegate), excessive heat and super-hot shutdowns.
    Aftercoolers increase effective compression ratios thereby increasing towrque. Be careful of overdoing aftercoolers without higher fuel settings as it may result in too low combustion temps - good for Nox outputs but bad for combustion deposits / oil acidity.
    Replacement turbos (original) are available from several specialists shops - Ie. nitro & turbo performance for around R5300. Aftercooler kits such as Cirrus go for about R3500.

    Except sometimes !!!

    I had one let go in an instant - it blew the shaft oil seal.
    The power went from 125kW to 400kW in 2 secs!
    It accelerated like a 911, belching a cloud of white smoke like the space shuttle.
    Fortunately it has a manual gearbox and I could "kill" it with the brakes.

    .... but that is the exception!

    Usually they give ample warning, like you said, and can be re-conditioned for a few grand.

    Intercooler on ANY turbo-charged vehicle is a BIG YES. You want optimum performance out of it, you intercool it, period. How you use the new available power is up to you. You can gain fuel economy if driven proper, or gain brute force, with less fuel economy if you've got a heavy foot.......like me...

    The Isuzu having a weak turbo is a lot of hogwash. I've taken a 280 to 416 big ones and sold it in 2005 for the 300. That 280 is still running today in Durban and I can give you Morgan's telephone number if you want to confirm that. The 300 is touching 200 big ones with no problem on the turbo. About 200 active members on the Isuzu Offroad web site, most of them in 280s and I've not heard of a single turbo failure. Blown a motor or two, but never a turbo. Engine failure occurs for one of a couple of reasons, each one of them under the control of the driver.
    1. Overheating due to no water..burst pipes etc
    2. Leaking/worn out injectors due to lack of maintenance
    3. Overfueling due to owner or unimformed person fiddling with the injector pump.
    4. uninformed people playing around with turbo boost pressures trying to increase performance.

    In the early days of TDs, which Isuzu started in SA, there were some failures, some mechanical, but the vast majority due to driver ignorance. There is a way to drive a TD, and it is different to a petrol. Once you got those under control, that turbo will outlast your engine, and on a 280 Isuzu that is a serious claim, and I stand by it.

    Before you buy, have it checked out by a proffesional, and then take care of it. All TDs do need to be treated with due common sense respect, or it can cost you a lot of money, and the Isuzu TD is no different, just more forgiving than most, if not all others.

    Thanx Sakkie and everyone else for the informative responces.

    I was just worried that I might buy a 280 TD and a month later I have to fork out R20 000 for a new turbo cause the previous owner sold me a dud bakkie.

    But R3500 for a recond turbo is not too bad I guess.


    Another question then......... if you guys claim that the 4x2 280 td D/C can get anything between 9 and 13 km/l, how does the 4x4 compare in consumption?

    I just got my 1995 2.8DC LE 4x4 a week ago, drove it from ape town to bloem and got 11.5 km/l at 110 to 120. I did deviate a bit on some gravel as well. It asked nicely I did some slow off roading and plenty town driving since, and will know what the average is on the next tank fill. Just waiting for the diesel prices to drop.

    Haai JD,

    Ek het 'n KB 4x4, net met die 300TDi enjin. As ek so luister is die 280 ligter op brandstof as die 300, en my regtervoet is maar swaar. Ek het nou al 22000km met die bakkie gery en my gemiddelde verbruik is 9.52km/l, so ek glo die 280 sal jou maklik 10km/l gee.

    I had a 280DT some time ago & was taken by affirmative shopping.. .. had a intercooler fitted at around 160000km and run without any issues till around 200000km, because its not a high performance motor the turbo`s live is better than most other turbo diesel bakkies. Recon & after market turbos is freely available & dont need to spend R16000 on a turbo, also keep in mind every 100000km you should need to change the injector tips.

    The cooler increased the power from a granny van to a very nice bakkie, but did not improve my fuel consumption as was told by the sales guy, but with ave 10km.l I didnt mind.
