The smallest of the ATP bolt-on WRX and STi turbos, the GT2860RS AKA GT28RS, is good for small engines, like the 2.0L EJ20, where fast spool is a priority. The GT28RS uses a 53.85mm turbine wheel with a 76 trim and 60mm, 62 trim compressor wheel to provide good spool characteristics and a nice power upgrade.
