it makes the cylinder walls thicker, to make it more resistant to cracking due to the hp and heat. if its a shitty tune the heat may still crack the walls though

if it has a good reputable sleeve such as: aebs, darton, golden eagle, ect. then you can always through anything at it. People with h22's (in short) just sleeve the block, put rods and pistons in it with a big turbo and have seen over 800hp easy

Yes it is, but theres a limit you can over bore them. golden eagle recommend you dont go over 89mm in h-series (stock is 87mm)

The bore may or may not still be the stock size. I installed Darton sleeves and bored my 75mm D16 to 78mm.
