well i went sick last night looking for info and i found nothing on a ls but i found something pretty good on the b20 .well the b20a was 1 of the worst honda motors ever made the rod stroke was just stupid and as to ne turbo mods it wouldn't last long,u could change the cranks with a b18 but why would i was more money when a b18 is cheaper so im just spending more money building a b20a true?id perfer to fit a b16 head and b18c intake manifold and have a almost perfect 174.1 r/s !that would be perfect for turbo !but for now im not that interested in vtec ,ive been in a intergra type R and 7,000rpm is a long time to wait for vtec to kick in ,compared to like 3,000rpm with boost,plus if i get vtec il need to buy a vafc and god no's what else ,im just not that impressed wiht vtec nemore
p.s was that 12 sec LS ,a vtec? do u no what he was running ?how quick can a stock ls motor rev ,compared to dohc vtec
