idle thought crossed my mind... how similar are the 2.5 and 2¼ petrol LR
engines, and will the 2.5 bolt straight into my series?

Only I had one in the 110 which I flogged (cheap) to a bloke, later found
that the poor running on the 110 was not in fact a dud engine at all, so
it's probably quite a decent motor. If he's still got it, I might try to
buy it back...

The 2.5 has only a marginaly better perfromance than the 2¼ on paper,
but real-world performance is far better - it's even much better
than the 2¼ 90 (twin choke carb) one. Definately worth a conversion.
Obviously its designed to work with the LT77 box, but then the 2¼ 90
engine in my SII went pretty much straight in (can't remember if the
mountings needed modding or not - it was a while ago...)

Every spare cell I have is saying yes..... so probably not.

In fact nah, you'll never get it to fit.....

If you have any trouble leave it here.. it'll fit!..... "Pass that big

My money is on the 2.5 fitting straight in.

From experience:

A 2.5 diesel will fit straight onto a normal series box.

The automotive 2.8 engines will fit straight onto a series box (are
they made out of 2.5's?)

A 5 speed box out of an early 90 will mate straight onto a series
engine.

Are there any issues with prop-shaft lengths when doing this, particularly
the rear prop on a SWB Series III?

What were the 2.8 engines fitted to?

things with rich owners. It's a conversion on the 2¼ / 2.5 engine, takes it
up to 2.8 by extending the stroke and fitting special pistons. Costs mucho
dinero, though, sadly.

Were we perhaps thinking about the BMW 2.8i used in South Africa?

Nope the one Tom refers to is a Landrover engine tunned to the edge if my
memory serves me right and is located in deepest darkest Staffordshire (UK).

Same answer though

but there is a 2.8 conversion on the 4-cylinder LR engine, which by all
accounts makes it into a monster, with more torque than the V8.

You will need some new ones!. Also worth remembering that the 90 box
will be permenant 4 wheel drive too..

I think that a standard lwb rear one is close to fitting (on a SWB
landy)

Yeah, I was thinking of the one made my Automotive components (see
adverts in the landy mags). You can spend an awful lot of money
building one for yourself!
It may cost more, but it is quicker and easier than doing a V8
conversion!

vaguely on the subject, does anybody know of a _good_ 2.25 / 2.5
petrol engine for sale? S2 comes back soon, and the engine is the
weak spot. quite fancy new, but it's fairly big bucks.

I sold the 2.5 from my 110 to Hannaford - later it became apparent that the
problems were not in the engine at all, but were a faulty gas mixer. Since
I didn't run it on petrol, there was no comparison to make that obvious.

he may still have it, mind, he's a long way from you.

01239 710579 - mind, I was toying with the idea of having it back for MY
series... but the engine in that seems reasonable, so probably not worth the
effort.
