1987 110- Which engine would it be?

I'm looking at Land Rover 110 models that are for sale at the moment, and could use some help clarifying which engine models were fitted standard.
Many adverts state the engine type, like the 1996 300tdi thats out of my price range, but there is also a 1987 110 SW advertised that doesn't say.
Would it be the basic 2.5 diesel, or the TD?
If its the turbo, would that be the 19J?
Last question lol.. Should any of the engines be avoided?
I hope to get a 200tdi which I believe is 1990 (G) onwards
Thanks!

v8 petrol, 2.5 petrol, 2.5nad, or 2.5 td 19j assuming its standard avoid the 19j very rare to get a good one

cheers steve
