I just got done reading an old magazine from 2000...and in it...a couple of guys from Skunk2 said that the intake manifold on a b16 and Type R flow better than a GSR one....ok so...depending on how much i could get a b16 one for....would I see a worthwhile increase in power if i switched out the Gsr one for a b16 one? Like i said...I havent looked into how much a b16 one would be...but if it alot cheaper than a skunk2 one...would it be a good idea?
