19J cooling

So what are my options for this conversion? The original viscous coupling works well enough, but will it fit behind a standard rad is the question.

I don't want to move the front end forward as I was looking for a standard appearance, so if not, could the radiator be pushed forward slightly in the front panel? Failing that, what about fitting a 2.25 water pump and fixed fan (assuming it's any shorter.) I'd rather avoid electric fans really but can be done if necessary.

Can you not fit a fan on the other side of the rad? I was looking at a series 1 recently that had been modded for trailing, it had its fan between the grill and rad, looked quite good.

Electric fan in front of the rad would be doable, but I was hoping to stay engine-driven for simplicity. If there's enough space for an electric fan before the radiator, I might try shifting the radiator forward into that space to make room for the original viscous fan. A big engine-driven fan with a proper shroud shifts a lot of air, and I don't want to compromise on cooling with this engine.

My Perkins sits close to the rad and so I have an electric fan in front of the rad. I would go that way anyway as its good to have the electric fan as an option and its simple - you can just use a switch. I've just done 200 miles (loaded) in 80deg heat on the motorway and the engine temp was higher than I would like and the electric fan had to run the whole way so I'm looking to squeeze in a small engine fan into the little space I've got to give me 2 fans Would that option work for your set up?

All comes down to space between the engine and rad. Might be a case of dropping the engine in with the original fan fitted, then see how the radiator lines up. The radiator is made for that engine and only a few years old so would be good to make it all fit in and keep a standard cooling setup. The 109's original radiator (and petrol engine) is long-gone and it had a knackered 200tdi shoved in badly with no cooling fan and a questionable disco radiator!

With 19j stick with original cooling system if you can, they do need good cooling [ not having an intercooler means inlet air temp is a lot higher ] and the in rad oil cooler working. Ran one for 15 years, had twin electric on mine. [ in a 90 ]

Is there any reason you cannot add an intercooler?

Not if you can find room for it, the rad for a 19j doesn't have room in the frame for one like a Tdi rad.
And you have to find a way to get the hoses to the intercooler.
Quite do-able if you have time and ingenuity, but it might be easier to get a Tdi and fit it.

We're tinkering with an engine at work with a water-cooled intercooler. I keep thinking that would be simpler as you only have to route small-diameter water pipes to the front.

That sounds quite interesting, although not in a Land Rover context. Pics would be welcome if you have any.

A NDA with the customer gets in the way of that! The basic setup is fairly simple though- air from the turbo passes through a water-cooled heat exchanger, and an electric pump circulates coolant to a small radiator mouted in front of the main one. Means a shorter and more efficient induction system with less lag. Similar to most supercharged engines and I think several manufacturers use a similar setup.
