I also have a 92 lude sohc I spent 35 dollars on an intake kit on ebay and I was amazed at the feeling of more horses it doesn't seem like much of an upgrade but I was surprised that I could acually feel it. I also spent a little more for upgraded exhaust got a performance one from midas, it was so loud I had to bring it back to them so they put a resonator on it so I could hear myself think in the car that was a little more about 150 dollars but it was worth it. And another cheep upgrade is tires get some Z rated tires the car has good handle by it's self but with upgraded tires you can out handle a lot of cars on the road. stereo I upgraded my entire stereo in the car go to crutchfeild.com great place nice prices, good subs don't forget I got twin audiobahns 12" in a bandpass box ebay with amp box and wiring 350 bucks with shipping
