I Have A question I have a 1990 integra Ls 4 door. The car is completely stock. I want to put a vtec motor in it. I dont know to much about cars. Will i have to replace alot of parts to drop a vtec in it? The reason im asking the car blows white smoke and the mechanic says i need a new haed gasket its going to cost no more then 700 parts & labor. So im thinking it might be better to get a new engine thats faster. But not be worth it if i have to change alot of other parts Thanks.
