Borg Warner 170307 OBS Quick Spool 1.0 Turbine Housing

Choose the 1.0 housing for quicker spool and a great upgrade to the stock turbo. If you've added an intercooler or just want an instant improvement in acceleration with decreased turbo lag this housing is for you. The stock turbo on the 7.3 OBS is a 1.15 AR which is ok for the non intercooled engine but can greatly improve the driving characteristics with a smaller housing.
