wtb: gt2871 or another t28

ok so the story is i got a sr swap and the turbo doesnt have a wastegate, so im either going to buy one of those, or spend a more and buy a used turbo with a t3 manifold. it doesnt have to be a 28.71 i just want a bigger turbo than the stock t25. im not that picky it just needs to work with the stock sr manifold flange and fit in stock location… thanks
