what would be the best engine to put in my 89 civic cause i think that i have one of the wort engine possible

 

Try going to the engine swap section of the forum. might have more helpt to give you there, or search.

 

I would say a ZC motor. They drop right in and the only way you would have to rewire is if it were not a si and then you only have to wire for mpfi. These motors come with 130 hp over your 80 something hp. To me it would be the best thing to do. Plus they are very cheap. Go to nippon-motors.com and you can pick up everything you need for about 900.
