Its good to see you have researched and have an idea on where you wan't to go with your car, it all points into the direction of a good little street car. It's very hard to roll all of your purposes into one car. Having an all-rounder including track and drift?, most of what you have suggested won't be relevant. A K series engine for track/drift is the first major fail, also lack of knowledge being a beginner is a major disadvantage. It's certainly a major task your taking on first your first time, although that's what the rolla club community is here for. And in saying that, an individual can certainly learn/acquire skills to save money, not doubting that. Maybe later on down the track when you get a good paying job, look at going down the road of a purpose built track/ drift car at a later stage. Cars can be major money pits! I have both built cars myself, and paid for work to be done, major $$ difference.
