Ok i know im going to get smacked around for this but my car is a 1998 that has the 2.0l l4-122 dohc engine and i am looking to start to upgrade it just so it is a bit quicker on the daily drive . what are the best ways to relatively inexpensively upgrade the engine. i am currently going through auto motive classes so i have a place to do all of it and most of the specialty tools are available.
