hi turbos are not the easiest thing to change on any car firstly you can get recondtioned ones for half the price of the dealers one and it has the same warrenty but they are all funny about getting someone who knows what there doing to fit them as the problem with turbos is the heat they generate and need a good oil supply to them so they usually insist on replacing the oil pipes and changing the oil and filter and clearing all the inlet pipes of blockages and flushing the its oil cooler as for the catalystic converter the problem your fiance is going to have is that this is another item that gets that hot when you come to remove them the bolts and sensors are weled together and are very difficult to remove it all depends on how good at taking things apart and putting them back together he is best of luck yates210456.
