yeah well get any t3 or t2 based turbo if you are going cheap. dont boost over 6-8 lbs unless you know what the hell your doing, and have fuel management.
my buddy got a t3 from a junkyard for 50 bucks and it lasted him a year until he had enough to get a new t3/t4
get a stock S13 or DSM side mount(s13 will bolt right on)for a hundred bucks or so. then get a 1st gen DSM blow off valve(with the flange tube), get a log-style manifold(fuck the cheap ebay tube manifolds), quality steel braided oil lines cuz theyre cheap, any aftermarket downpipe for like 150 bucks, upgraded injectors(370cc is good, stock SR sized), and a walbro 255lph pump, and a basic boost controller, and a basic fuel controller. should be around 1500 or so with reliability.
