For a straight fit you'd need to swap the turbo + inlet and exhaust manifolds, as well as the flywheel housing. The Disco has a low mounted turbo whereas the genuine Defender one is mounted high up. With regards to the flywheel housing, they are the same casting but there is a difference in bolt/stud pattern, it is possible to modify one to fit the other, but if you've got the original you may as well swap it and replace the rear crank seal at the same time.

picpoki Posted January 13, 2010 Share Posted January 13, 2010 Housing is easy to modify. You only have to enlarge pre-drilled holes and tapp in the thread. Quote Link to comment Share on other sites More sharing options...

JST Posted January 14, 2010 Share Posted January 14, 2010 For a straight fit you'd need to swap the turbo + inlet and exhaust manifolds, as well as the flywheel housing. and the timing cover Quote Link to comment Share on other sites More sharing options...
picpoki Posted January 14, 2010 Share Posted January 14, 2010 Why timing cover? At the moment I`m converting 2.5 petrol to disco 200tdi. I have the engine mounted and there was no need to change timing cover. Quote Link to comment Share on other sites More sharing options...
western Posted January 14, 2010 Share Posted January 14, 2010 because the Discovery timing cover will foul on the Defenders steering box, the timing covers are a different shape on these 2 versions of the 200tdi. Quote Link to comment Share on other sites More sharing options...
picpoki Posted January 14, 2010 Share Posted January 14, 2010 Does it fouls on RHD? I have LHD and I don`t have any problems. Quote Link to comment Share on other sites More sharing options...

I have the engine mounted and there was no need to change timing cover. only if you are changing the manifolds over to Def ones as per the reply in my post. other wise the turbo IIRC exits in the rear of the timing cover. If you are keeping the disco inlet and outlet manifolds then you dont need to change the timing case. it will just clear the PAS box. the fan will need sorting though, cutting down or replacing with electric ones as that will contact the steering box.

Mine clears the steering box with no problem. Even the Disco viscous fan is suitably clear. However, I fitted an electric fan instead. The Disco fan setup seems too far off centre of rad, and rad cowls don't line up. I did fit new engine mount rubbers though. Quote Link to comment Share on other sites More sharing options...
picpoki Posted January 18, 2010 Share Posted January 18, 2010 Could somebody help me with alternator connection on my conversion from 2.5 petrol? I saw it was written on forum before, but I can not find it. Two thick brown wires are connected together to ...? And the thin one is for warning lihgt that goes to....? W is for RPM gauge IIRC?
