people say a ls/vtec or a b20/vtec only last long if it was built right, well what do people mean by that? because i always see people say that, but can they define what they mean by that. do they mean the person that's doing it has to know his shiet? how bout the person does know his shiet because a person that owns a shop should always know what they are doing when it come to swaps or whatever. or is it because some people go cheap on building a sway like that? i just want to know what do you need to build a successful ls/vtec or a b20/vtec. like what part should be replaces etc.... because im planning on building a b20/vtec with je 11:1 piston, so i want to know what i can do to make it a successful swap.
