After the last few days worrying about a blown turbo that wasnt, Im thinking now about taking preventative measure, and replacing the turbo as a matter of course. car is on 90k now, I have drove the last 20k and no idea about internal condition of turbo. So my thoughts are to opt for a 150pd as a bolt on upgrade. However im wondering, what are the differences between the 130 and 150 turbo? Could i just replace the innards of my current turbo with a balanced new 150 cartridge? Or are there more differences? Any recomended suppliers? The safe option is obviously to let the garage supply and fit. Any other turbo option? Along with this ill be expecting to have new boost pipes and higher capacity intercooler, and a remap to suit. Not looking for crazy power, its already pretty good with a remap alone.
