Firstly hello! I've recently changed from a D40 Navara to a 2005 Vito Dualiner Xtra Long 111Cdi, and it's a really good vehicle! I use it mainly for towing caravans as part my business and actually it does this even better than the 200bhp Navara (albeit more slowly up hills ) and we can load up with kids, dogs and a van full of antiques as part of my other business. However along with the usual bodywork imperfections that I intend to sort out in due course it has done rather a lot of miles, 240,000 of them to be precise! So although it seems reasonably healthy at the moment if you ignore the diesel pump clatter under severe duress, I imagine that given the hammering it'll receive over the next few months towing caravans some 1000 miles a week on occasion, this won't be the case for much longer. So what I need to know is when the time comes, how easy would it be to upgrade a little to say the 115? Or even just the 112 or 3, I imagine the lumps are the same, and marry up to the manual gearbox correctly, but what about ecu's, exhausts, turbos etc etc. Any help greatly appreciated!
