    Is anyone aware of a part no for a engine block for this model, speculating on whether to build a "new" engine from the floor up.

    err479 ,which is turbo diesel block ,turbo feed and drain are blocked for n/a uses, you need the later main bearing set too ,but its the same block apart from those , one block now covers all 5 bearing 4 cylinder petrols and diesels

    Ok thanks for that. I noticed another block casting (part no err2639) is also available from turner engineering. In your expert eyes would that be preferable even though the block you mentioned does cover all the 5 bearing 4cylinder petrels and diesels.

    From this website they are both the same price. Thanks

    What do you mean by bungs? Also in reference to your first post when you say turbo feed and drain are blocked for n/a uses, or am I just being dense.

    Lastly, as I intend to build, not recondition an engine would you rather build a n/a or a turbo, I personally don't know which is better.

    the bungs for the turbo feed and drain
    depends what you want ,if 2.5 n/a has enough power for your needs id go n/a

    Yes, and a bit more. But it needs to be a good one, doing that in a 200k example is unlikely to end well!

    If everything is about right, 2.5 na should get near 70 anyway.

    If faced with the choice of a brand new n/a or turbo which would you choose?

    Probably na. It was one of the better diesels landrover made, both in design figures and in practice.

    Very good for landrover usage, farm, laning, local mileage. Not very good for a high speed commute on crowded motorways.

    Also, if given the choice of a brand new 2.5 petrol, I might go for that instead! :) Subject to limitations above ^^^^^^^^^^^^^^. ;)

    Why a 2.5 petrol? Btw my main objective in building a new 2.5 petrol-diesel n/a-turbo would be to get the most power possible without a tdi if that clarifies the choice.

    NA makes 67 horse, turbo makes 85, no doubts about that. 2.5 petrol less likely to get taxed off the road soon, maybe a consideration if you plan to spend a lot of money|?

    Also worth pointing out that if you're building an engine from a bare block, the 2.5 petrol responds readily to tuning so with the right cam, head and carb it would be in the 90s. More even than the 19j.

    As mentioned above, depends what you want to do with the end vehicle. The N/A will get close to 30mpg, 35 on a long 40-50 mpg run, and is easy to maintain/long lived. Not relaxing near motorway speeds though. A petrol is going to be more powerful and a bit nicer to drive , and easy to up the power - uprated head from turner etc. - but 20mpg is hard to achieve.

    What mpg is realistic on the turbo?

    Driven gently local mileage, about 28-30. Cruising at 70 or towing, probably half that.
