sorry this is long but i wanted to be specific. here goes. this guy has a 91 rex si w/ a b16a swap that he did himself. the body and interior are in good shape but the motor has a few problems. the car ran fine up until about a week ago except for a vibration that started at about 40 mph. we think the vibration is due to a improperly mounted rear motor mount, but aren't sure. in an effort to stop the vibration he replaced the axles with new as well as new wheel bearings. this didn't work that is how we came to the motor mount conclusion because supposedly the rear mount of the $350 motor mount kit wouldn't work so he got an integra mount instead...? the other problem is the that the water pump went bad and the engine got hot and went dead. we pulled the plugs to check for water and saw no signs and replaced them with new ones anyway. i also checked for the usual sign of a blown head gasket and saw no "milky" substance on the oil stick, so i don't think the engine was damaged, but i am not sure? we then proceeded to pull the plugs again and check for fire. i couldn't tell whether they were getting fire or not. i am pretty sure it is getting fuel to the combustion chamber though because when we had the plugs out and he turned the engine over i could smell gas coming from the plug wholes. i guess my questions are: what could be other causes of the vibration besides the mount?, why do you think it is not starting?(like there couldn't be a million answers to that question, but just give me your best suggestion-distributor, etc..), and do you think the car is worth buying? to help you with the last ques here is a rundown of the car: 91 rex si, red, good paint, good int, cdplayer, no apparent leakage around hatch or sunroof, and a b16a motor swap which includes all the necc.: engine, tranny, ecu, harness, new axles, mount kit, new radiator, and what ever else it took to get the thing wedged into it. the engine is installed, but the guy didn't do a very good job. pulling the engine and re-installing it is an option, but do you think it is necc. also a side note, the alt. pulley hits the frame when he turns the steering wheel a ceartain way. obviously not a good swap job. do you think it is worth the time and the $1300 for the car? to buy or not to buy?
