    I think you are right regarding parts/ spares with the 2.8L though......hmmm, the disco has every modification you could want and its not going to be sold any time in the distant future....so, off to ponder what to do next. Cheers All for your thoughts
    There is not much practical difference between 200Tdi and 300Tdi. Although many things were changed, they did little to change performance, but did make it a bit smoother and other things like serpentine belts.

    The main reason for the (little) performance increase is due to slightly higher boost pressure.

    It should be possible to fit a VNT turbo to a 200Tdi exhaust manifold, whereas a 300Tdi will need a new manifold.

    if you upgrade the turbo to enable more air to the engine, it is simple to increase fuel to get more power. The VNT turbo provides more air at lower engine rpm, so can support a broader spread (starting at lower rpm) of useful torque.

    Power is increased by burning more fuel. If you increase fuel without increasing the air flow, then egt will increase dramatically. If the air flow is increased, the egt can be kept to acceptable limits.

    The air flow can be increased by using a larger displacement engine or by increasing the air charge density using a turbocharger.

    Turbos don't increase the stress in the engine significantly as they don't require the engine to rev higher to produce more power.

    I have a 2.8tgv in my 110 trayback. my 300tdi did a conrod/crank bearing at 230000km. i tow a 1.8t trailer 5 days a week.

    the cooling issue was solved by finding a thermostat that cracked earlier. there are many issues with the 300tdi and in general LR's.

    i have stated my opinion here a few times in the end it always ends in a psiing match by the realists and the brand blinded.

    its not a drop in replacement but can be done. if you have the 300tid some bits can be taken from it like the plenumn to make the fit better.

    to get the best and longevity out of the 2.8 i personally think it should be mounted in the 200tdi postion, then a full width radiatio and a full width intercooler could be fitted. But you wont find the bits to adapt the short bellhousing to r380....although one could be made.

    if i was to do the engine swap again and i was able to get it engineered i would put in a brand new chev alloy v8 and auto.....and at the price that you can buy the 6.0s at youd do it for the same price or less as a 2.8tgv!

    the 2.8tgv is not "just a bored out" 300tdi....its a whole new block, with improved water galleries, has a different bore AND stroke, has different intake manifold/turbo, different oil cooler etc etc......

    the story i have is that when LR went to the TD5 they still needed a low tech engine for other parts of the world....the sold the rights to International in Sth America. they built the 300tdi and developed the 2.8 from it. it went into many vehilces over in Sth America....now some evidence of this is the engine i got on crate, would have bolted up to a td5 defender alot easier from what my mechanic said, simliar engine mounts, same type of fuel lines connectors etc.....

    as good as the 2.8 is it doesnt solve the LR cooling issues,intercooling issues, electrical issues etc etc....

    i think the isuzu engines are very good, the only down sides being weight and vibrations. not something that is good fo a LR especially how far forward the engine is in a 300tdi defender

    Dave Ashcroft sells a short R380 bellhousing.

    its not the bell housing thats the problem, a 200tdi lt77 bellhousing will work to a r380, its the drive coupling(forget the correct term) that joins the engine to gearbox. I know someone that made one, be he is the exception that makes the rule....so to speak

    Ashcroft said they could supply the input shaft and housing as well as the bellhousing. Still waiting for a price.

    last time i spoke to them, which was this year i believe, they said parts were very hard to come by, some stuff was on back order for a very long time with LR and pretty much no hope.

    are you looking into a 2.8tgv?

    One of the Sydney LROC has the “brazilin” fitted to his 130 some time ago and loves it. At the Graeme Cooper Dyno day his vehicle’s out put beat all the diesels (almost positive) chipped and unchipped.

    He even mated it to an auto transmission.

    To the best of my knowledge he’s had no issues with the motor and when it arrived it came with everything you needed to “bolt in”.

    Hi Scott,

    was this 130 a td5 or a tdi?

    my definition of bolt in, is just that....no modding, welding, cutting etc etc....

    i think you will find that this is not the case....for one the turbo exit is 90 degrees different to stock so at least you will have to get your exhaust cut and modded..... engine mount and oil filter are an issue also

    there is more, like i said i have one in my truck, i have been through this. Rick from Ricks4wd did the install.

    regarding issues, is he still running the standard LR temp gauge.....i hope not! and i hope he got the coolant plumbing correct as its a bit different to stock.....

    just because we arent aware of issues does not mean they arent there.

    Must have been a pretty quiet dyno day if a 100kw engine took it out.
