all that money spent on the b20 frankenstein conversion is pointless. dont get me wrong i would love one but your better off sticking with the 1.8 b18c6/4 or r whatever it is. they got the thickest sleeves i have heard snooping round the honda forums. the b20's suffer from det or summit. although i could be completely wrong. just an insight. although they sound awsome!!!! maybe i might build one for the ek.
