Anyone here knows what to modify with the 93 corolla 1.3 that currently i owned. I just changed the exhaust and the air filter. I also included a Grounding Unit Wire to slightly increase the horsepower... is turbo a good choice to be included? if so, which turbine is solely recommended for the car? then what if i want it to be an N/A tuned car...what items for the engine can i add to make it "fierce"? I saw a few corolla with the fake blowoff sound...where can i get it? and whats the price roughly?
