Gokart's 1989 Nissan 240SX

As of now, the car is completely stock, with the exception of the paint, it has a fart can on it, as the stock muffler that was on it rusted and fell off. I plan on maybe getting some rims this winter, as well as when I am done playing football, doing a motor swap, still debating between the rb25 and the sr20. Any suggestions, as well as comments or criticisms on my car are more than welcome. Just please be easy, as this is my pride and joy, and I take great pride in keeping my car running as well as in great condition. But I have my mind made up on a few parts, such as the Tein SS coilover system, Megan drift spec exhaust, jdm s13 front end, 5 lug conversion, and lsd; there are still some mods in the air that I am still researching and I am open to any ideas anyone has about any mods.
