i take it uve got a N/A starlet IE non turbo... The best things you can do in my opinion is: 1st off strip anything out weight wise you dont need, spare wheels, jacks, seats. etc only slowing you down! Service your car! fresh oil, filter, plugs will help it run to its max potiential... then the usual breathing mods! Make sure the car can get the air in and gases out as fast as it can.... then i would just save and buy a turbo'd starlet or drop a turbo lump in Have fun tuning hope this helps!
