i currently own a 1985 honda civic 4dr. its still running a carb under the hood and i want to replace with a newer engine. i wanna engine swap but i have no idea where to start. what engines can i put in there and how would i do it? please help.

 

Go to http://www.hasport.com. They have most of the info that you will need.
Personally I would put a b18 in it then later upgrade it to a ls/vtec.
Either way you are gonna have to do alot of wiring. Good luck.
