Here's a list of things I would do....
18" Chrome Spinners
24" Tall Drift Spoiler
Drift Body Kit
Lambo Doors
Underglows
Spray paint parts of the interior
4" Muffler
Altezza Tail Lights
Put a "Tornado" in your intake
Pillar gauges and gauges all over the place. (looks good on N/A SR20's)
Last but not least, take the Nissan badge off and replace it with a Honda badge
Just kidding
