Ls/vtec Or B20/vtec?

Okay so after buying a used b18a1 to go in my 91 integra, no more than a week later the motor got stolen out of my garage. So, should i go buy another b18 and do the ls/vtec set up or should i go get a b20 out of a crv and throw on the b16a2 head? I'm thinking about going with the b20 since it's "unique" but i'm not sure if CA emissions will be a problem or not...any ideas? Also, will i need the ecu out of the del sol si or from the crv, or can i use the one i have in my integra already? thanks everyone!

buy a b18b/a and bore it out to 84mm :thumbsup:
