It's mainly the top speed that is the issue and at the minute it's been in the garage for repairs more than it's on the road. I realise top speed isn't going to be greatly improved however 5mph on the motorway make a big difference! Maybe the 200tdi is the way to go. Would a new gearbox be required if I went for the 300tdi? Also the discovery engines seem a lot easier found. Would there be much work involved in putting a disco engine in. Obv the mounts will need adjusting by much else? Many Thanks Matt

Hi all, firstly I would like to say hi as this is my 1st post as this forum was recommended by a friend. I have owned a 1989 defender for the past six months that has the original 2.5td engine fitted. The head gasket now needs replacing therefore I thought it best to look at replacing the engine as the current one is a little sluggish. My question is what would be the best replacement? I have been advised the 200tdi or 300tdi is the most common replacement. However which is best in terms of simplicity? And would I need to replace the gearbox if I was to switch to either of these? Many thanks in advance.
