i don't know if i went ls/vtec i'd spend abot the same amount of $ getting it built right as i would buying a b18c. i'd rather just go with a motor that was built for vtech rather than modifing it. i mean it does'nt sound like a bad idea if u got a ls teg but i would be buying a whole swap and i'd just be more comfrotable going with the sir-g b18c...thats just me though.
