Buy a gaskit set and port out ur intake (easy to do if ur not hopeless) 4 prong platnum spark plugs and plug wires labour u do ur self and most things arnot to expencive if ur thinking more strip less street u can pull excess weight out which cost nothing but a little time like rear seats carpets headliner sound deadning meteral( which is heavier then it looks) moving the battery to the trunk to help with weight distrobution and a chip or tune for 93 octain can really help to. Swaping gears helps to. Not all these things nessaserally add power but deffanetly help in the delivery of what u have there for seaming as though u have more e.i. The diffrence in a 500 hp 1400 pound car accelerating or a 500hp 3000 pound car accelerating.
To port ur intake ull need a dremal style device ether plug in or air and a good ball or diamond ball bit. gaskit matching is nice but dont take to much off! (leave a little room for error) and throttle body and or injectors but now were getting up there in $$ lol
