EGL, in my experiences with the LS/Vtec they usually suck, i only have 1 friend that has built one correctly, it is insane fast, but outa the like 10 people i know that have tried to do it right, hes the only ones id trust. if u arent good with engines and all that, dont go ls/vtec, ull get a shop to do the work and they suck. stick with a GSR id say, i have an LS in my 90 CRX, and i wish i had vtec b/c i get bored once it hits midrange in 2nd, yes the turbo will help that. but turboing a gsr will be faster but more expensive. if i was u id buy a gsr, get components u can use for when u get a turbo, like bigger exhaust intake cams and all that, so then when i get a turbo down the road it wont be as expensive, and it will roast any LS/T on the road.
