I know this topic has been covered ive spend a majority of the last 3 days looking into this. I baught a 90-93 b18a block from the junkyard for 70 bucks and my friend baught a 91 ls/vtec and got a free b16 head and gave it to me to i can o lsvtec also. Now heres the question. . for the b18 to go into the civic (1995 civic si) what kind of mounts will i need any new ones or will i need to order some? I heard i can use a conversion kit for the wiring harness to make it compatible with the ls? Am i going to need to buy new shiftlinkage and axles as well? I think that is all my questions and if anyone has anything to add about throwing the ls in please give me your .02.

 

You are going to need mounts from a '94-up integra (but you can reuse your civic upper tranny mount).
You will need B series axles(including intermediate shaft), shiftlinkage, transmission(w/ clutch and flywheel), vtec ecu(or have your ecu rechipped), B series radiator hoses, and all the necessary parts for the lsvtec conversion.

 

hell yeha man very informative.
