modding a 90k mile car
Is it a good idea to mod the engine of a car that has about 91k miles? By modding it i mean get a split port intake port the upper and lower intakes and throttle body and get ported heads and a cam. Would this be ok or would it cause the engine to go? I was wondering because i want to do all this but my dad says that it will be a waste of money and that i should just buy a new crate engine.
