Stock is a T3-45. After hours of compressor map comparison, I think a Garrett GT2052, 52mm, 50trim, .51a/r is almost an exact match. A GT2056, GT2252, or GT2259 would all out flow the stock T3-45, or even a T3-50. So a variable based on the GT22 looks to be ideal for a little more power. I can't find a map for a GT23, but it probably would also work.
