I'm new to this forum and picked up a civic, it has a d13 carby non vtec in it. It's my first car and I am going for my P's soon, I brought it for $600 in decent condition, drives awesome. Was just wondering if there was anything I could do with this engine to increase hp and torque just to get abit more out of it at a reasonable price, I'm not looking to do engine swaps or turbos, just looking for the little things that could help with some changes in power, any answers will be much appreciated!
