I’m new to this sorry if my questions are dumb or ha e been asked. What is the cheapest way to make my 97 del sol si faster. The motor I have is starting to tick a lil so I’m going to buy another motor thats the same. I was curious if there was anything that I could do to it with out spending a lot of money. I read some threads but I don’t understand the abbreviations.

can I switch the head an make more power, the manifold, throttle body, ANY HELP IS VERY MUCH APPRECIATED

This is the car I need help with!
don’t worry the wheels are my back ups, my other wheels are getting powered coated
