This may be opening a can of worms, = but... Has an engine with these upgrades been dyno tested?  Is there a power = increase to justify the expenditure and the added stress on components. I find = my 1.9 to be the hardest/toughest little engine I've owned, bearing in mind my champions are my dodge super six and my ford in line 4.9.  I am = currently installing a bone stock 1.9, new rods,mains NEW = heads,yada,yada.. and the only mods I would think I really like would be an oil cooler. All this = rambling aside , are there any hard figures to be had?  Curious Jim
