the "unrealiability" of the ls/vtec is way waaaay down in the dark ages. the unrealiable aspects has been fixed. all the previous ls/vtec setup back in the days had some bugs in it -- i.e. improper lines, improper installations, improper machine work that made the vtec head to be swapped to the ls block unsuccessfull, etc. the only unreliable things that i keep hearing about ls/vtecs are the ones that didn't do the job right -- leading to oil leaks here and there. even installing the headgasket wrong.
i've had and ls/vtec for 3 years back then and it was stock. stock gsr head, stock ls bottom (with 137,000 miles), gsr oil pump, ls water pump, ls timing belt. i even squeezed 55 shots of nitrous in it and it still held. no oil leaks, no nothing. just oil changes every 3000 miles.
now i have a fully built b20/vtec for almost a year now and i don't have any problems with it. the setup is just like an ls/vtec, but with more displacement, and bigger bore, and all that good stuff.
