1991 civic LX ZC DOHC motor swap
 

I have a 1991 Honda Civic LX sedan. I want to put a ZC DOHC in it. However I have a Dual Point feul injection system and a stock motor. So what I need to find out is if this is do-able, and if so, will the intake manifold thats in it, fit the ZC motor or will i need to replace it?
