I recently sold my mustang, and have picked up a 93 civic with a d16z6, and also a 94 integra with a b18. I have a child on the way and my fiancÃ© advised me to get a 4 door car that was good on gas so I said okay and bought 2. This is where my problem is. The b18 has a terrible valve cover leak. It has been neglected for so long that when I got underneath the vehicle there was oil all over my two rear calipers. The suspenion in the integra is also shot, and only the driver door controls work, and the rear passenger door won't open... The body is also spray painted w.The d16 is a nice clean engine with no leaks or knocks but it just seems so weak in 2nd gear. Maybe I am just not used to such a small sohc engine but I want to know if there is something I can do about that right now just to make it a more comfortable daily. My real question is should I keep the d16z6 and do like the vitara build or should I go with the b18 and do like an ls vtec swap. Keep In mind I am wanting to use the civic chassis. Just let me know what you would do in my situation and let me know what is going to be more cost effective.
