Well basically my dad owns a machine shop, and i want to increase hp in my bmw. so to take advantage of the fact my dad owns a machine shop how do u bore and port and engine. Is there a certain amount of metal i take off before i screw up the holes?
Another thing is if i do bore out the engine, should i get bigger pistons that fit the hole better. Is it better to just buy some, or make some?
Thanks for any help.
