just make it a nice car, they are quick enuff as they are - stuff the turbo 33 owners and their comments on how slow NA cars are. Lower it, good mags, good exhaust system, cold air induction this should be sweet cos u wont be using alot of petrol and you wont have problems! if u are going for the track then maybe yeah spend abit on the engine, but for a daily driver spend more on luxuries and style cos on the road u dont need the performance, and dont worry NA skylines do beat lancers and commonwhores lol
