good job on your mods man... white ones looks good and fine... but the black looks nasty... its up to you... but both looks awesome... hehehe...
Just my opinion, paint the rear/front lip man... you'll approciate the drop more... hehehe... also the grill...
As to whats under the hood, I think you should choose either NA or Turbo... there are a lot of engine mods... but my 1st advice is swap your sohc engine to a dohc engine before you do any mods... that itself is already big hp gain...
