Hi mate, you may well be right, at the end of the day there's only a choice of bearings or oil pump that have been improved? I don't know being honest, thinking of going with king's main bearings and the 15mm pump, basically what the guy on lr time did, with no loss of pressure, does this allow higher flow rate whilst maintaining pressure? Again not sure, kings are highly rated by my machine shop and lots of builders on line and uber tube, but at the end of the day you pick your own poison, I'm at least semi retired now (20hrs) so have more time for the workshop, I know it can be difficult to time do all the necessary maintenance that they demand but I love to hear of people keeping on top of all those jobs themselves all the best
