personally i prefer the eg but if i was going for a b16 i would go for the ef because they are far more rare which means you get a lot more attention and they are also the fastest civic with a b16 honda have ever made if you are talking power to weight ratio
the ek produces the most power but when you work it out as power to weight the ef is better, i guess its a bit stupid though because head to head there wouldnt be much difference and you can always lose weight from a car anyway.
If you decide to try and find an ef go on http://www.4guk.co.uk" onclick="window.open(this.href);return false; its an ef forum there are quite a few vt's that pop up for sale on there and a few sir's if your lucky
yea only import mate like stug said, but if you look around i have seen a couple pop up on auto trader and ebay! they are a little bit lighter i think as they are a more focused car (no luxuries) i could be wrong about that tho. Any civic equiped wit a B series mate your gonna be having giggles
