Don't waste your money on bolt-ons that won't do squat. You could spend up to $1k on Bolt-ons that may add a few ponies in the high end or you could save that $1k for a turbo that'll add 30+ ponies and actually be worth it. I wouldn't suggest peicing together a DIY turbo if you aren't experienced or are close with people that are. But if you know what your doing I say go with that option. I wouldn't save for a swap only cause by then you may want a new car. But if you see yourself making enough in the next 6 months to a year, then I say save up for the swap and don't touch your car till then
