Yeah a gsr is more reliable and less maintenance. LS vtecs are good if there built to handle the high rpm stress , but like anything, when ya start fiddlin with shit stuffs bound to break, and that's where the reliability issue comes into play. You really gotta consider on what you want outta your car in the end. If you wanna daily driver get the GSR, wanna weekend street terror build the bitch and go with the frankenstein build, ls\vtec.
Me personnally I rock a gsr, but I do got a buddy who's got, or should I sadly say had, a built Ls\Vtec runnin 15 lbs of boost in lil EG hatch. That little motherfucker pulled so hard. That bitch had forged internals , hondata S200 tune, the works, it was all good till he threw a rod. about a year after the build.
But at least I got my ol reliable still lol
