Need help on Turbocharging a 318

Yeah imma check out the turbo forums im not jumping in to this right away either.. Ive been looking on amazon/ebay and other sites to see whats cheap,im mostly looking at the turbo's around 250-350 bucks, to keep on the low side. what would be a good turbo, im thinking of a single for now, theres t3/t4 hybrids for 230 or so,what would be a good single turbo to run with my 318, as im not looking for 700 hp or so more like a quick boost in power around 450or somewhere in that neighborhood. Thanks for the help so far guys.
