Brand new Bulls Eye S259 Billet ETT turbo. The cast S259 wheel already spools fast, so the billet wheel will spool amazingly fast, and will support 600-650hp at sea level. These turbos are awesome and great for driving. These turbos are usually comparable to GT35R turbos, but compare the maps. I have installed an oil pressure restrictor on the feed side, to make sure oil pressure will not get too high, and hurt the turbo. I was going to install this turbo on a modified stroked 4G63, which usually has high oil pressure, with the balanced shafts and oil squirters removed. Most likely you will need it, but check with Bulls Eye on oil pressure to the turbo. Then there is a -10an connector on the oil drain. Again, common on 4G63 motors, where -10an connectors are used to drain oil back into the oil pan. Turbo is in a DSM exhaust housing, setup for an external waste gate. The housing is a 0.55 A/R. So if this is going into a DSM, it is ready to be hooked up, and start hauling ass. Just sure you have the mods to support it (IE fuel).
