well on the first you did all of that to the exterior of the car might as well add some more phonies and finish up the breathing on your car with a header and exhaust.... h:

well as for the interior, do you have a look in mind? that would help alot. guages look good but are either for show or go.. being that you only have an intake your guages would be more for show.. they help with a more aggressive race look but you dont have much "get up and go" to back up the look. aftermarket leather or even seats will give you better comfort and styling. even a carbon fiber dash kit or alumium dash kit, would help bring out the look of your car. the easiest way since i have no clue the look you want is open any import mag and take a look at what some of the feature cars have. even if your not into full blown show cars you'll get an idea of what extreme you want to go to.

lastly unless you have an automatic you have a 5speed not a 4speed
