I did everything the poor man's way and overall i spent about 2300-2500. Get the major components that you can't make like header, FMU, gauges, fuel pump, wastegate, couplings, fittings, and different size hoses for the turbo drain, fuel, vaccuum, and oil feed. i made my own plenum and up pipe. Add the cost of getting it dyno tuned and about 2500 bucks later your boosted and have a permagrin from ear to ear!
