i need some help from an engine man. i have a 92 civic si hb. im pretty sure im runnin 125hp stock engine, but its just not enough power, i need more. my buddy says he can get me a b16 for a good price, but i dont want to go wasting money if there is a better option. is the b16 good? how much hp will it give me? will i need to change or add anything (tranny, tach...)?
