I driving 5th Gen Civic too. My is 1995 1.6 (A) injection 4 door (SR4), i been driving about 2 years....when I buy that time (2005) is very expensive....35k that time. i not a racer or what drag-er, i just use it for daily drive point A - point B to work. i have no major mod on my engine bay just add some stablizer and struk bar. for the outlook i just respray the whole car (because is already 10years old car) and added a TypeR front lips + rear eg9 spoiler and 1 set of sportrim. It look nice already just touch up abit on the out layer because the shape is look sporty already (i buy this car path of this reason). For the interio i just change a Momo stering and some sport meter (just for decoration only) and a dual Din Sony CD player, the rest i just maintain it clean. You can post this topic on ZTH honda forum, i think over there have a lot of Master or Sifu mod on Civic can give you more suggestion.
