Hey my name is Eric, I'm new to cars and want to get into them. I just bought a Sentra Nismo recently and wanted to know what I could do to increase the performance specifically for that car? I wont be doing the mods anytime soon, but I would like to see what others think are good mods that work for this car, so I can have a list of what i can do in the future. I would like to keep this car for as long as possible. It was a pretty good deal and I'm currently financing it. What are your suggestions? An engine swap? An ECU tune? A new CAT system? I believe the car is all stock, I would like to see what I can start off with first to increase performance. It has a 1.6 L 4-cylinder engine that is turbo charged and a CVT transmission with a manual shifter. Any recommendations are appreciated, thank you.
