i have a 91 integra ls
the b18 is a good motor (wish mine was a vtec but i digress)
a good combo my buddy has been working with is a b18 block with a si civic head.
for my swap i couldnt find any1 to do it for less than 1500 labor so forget that, i do body work not engine so im going to bosces again for auto mechanics and doing it my self,
the civic is a good car because of the flood of after market parts but i think its overdone by ever idiot who thinks they can take my friends supercharged s2000 i would go for a old accord or prelud dont see many of them around
good luck
