I drive a 90gxl and want more power. Money is a little scarce right now so i cant go turbo this summer. I would prefer to do mods that i can swap over to my turbo engine when i plan on going turbo. Current mods are

cone intake
racing beat header, 21/2 inch piping to single muffler
racing beat sway bar, koni shocks, eibach springs
kumho 712's
Did most of my weight reduction i wanted to since its a daily driver

Whats next.... i need emissions

 

u could get an S-AFC

 

what kind of gains should i expect? and s-afc needs to be run with atleast a air/fuel gauge right? any other mods that should be added alongside the s-afc
