Will a 2000 honda civic engine fit a 95?

yes it will fit. just use the 00 engine mounts and engine harness. 92-00 civic have the same engine block and tranny except the heads r turned differently. and when u say ur car is shaky, then ur lug nuts are loose. i had that before and when i tightened them up, the car didn't shake. also ur car burning too much oil is caused by not having the engine in correct timing therefore ur car wont start right away and stalls. take ur timing belt off and put the 1st piston all the way up by moving the crank pulley. then the cam gear with the "up" mark at the top pointing up towards the hood. u don't have to remove ur head but remove the spark plug and use something that will fit thru the spark plug hole. if the object ur using goes very after then ur piston is completely down or in the middle. don't try to turn the cam gear or pulley with the belt on. this will cause damage to the valves.
