As linger said, we do it cause we want to be faster and quicker. If you want it to last forever, then leave it.
I personally have a 32, with minor mods...exhaust fmic, fuel pump, tune(remap, chip), more boost, coilovers, swaybars. i havent had many problems with it, and its fun. I replaced my coil packs, but as they were 16 odd years old, i expected that.
Its up to you really man, if you want it to go quicker..then mod it lol
