can anyone please explain meth injection to me? i mean i get it for the most part but i wanna fully understand it, and is it safer or less safe than a small shot of nitrous...? and what other mods can i add to safely add boost, like sleeving, and someone told me of a small ring they can drill? into the top of the block and then pound copper wire into to help the integrity of the gaskets? i have no idea im not too smart yet

 

there is a big post called official met water injection post....

check it out

its up for grabs which is safer. why do you wanna add boost? you have a 2.4 where are you getting boost? that ring is for a specific type of gasket. pointless you go out and buy if you dont need one. what are your goals and what do you have done already?
