1000 bucks is hard to use unless your sourcing someone elses' pile 3rd hand.
used turbos can be had for 250 bucks... small t3s, 16gs, etc. same for a manifold. 100 in lines, 200 injectors, 100 downpipe, 100 exhaust
and you tapped budget already (and good lukc finding a $100 exhaust) and still need to get a waste gate if the turbo isn't internally gated, a bov, a catch can, misc vac lines, fittings, fluids, tap the oil pan, and of tune.
