1994-1997 Powerstroke .84 A/R Turbine Housing (BW-170290)

Brand new Borg Warner .84 A/R turbine housing for 1994-1997 Ford F-Series trucks running the 7.3L Powerstroke. Drop-in upgrade for the TP38 factory turbo — the tighter A/R housing pulls the turbine spool down into the lower RPM range where OBS Powerstrokes spend most of their time.

Direct replacement housing only — the existing turbo center section and compressor housing are reused. No tuning, no fuel system upgrades, and no injector changes are needed for this swap. The factory TP38 was bottlenecked at low boost in stock trim, and a smaller-A/R housing is the most cost-effective way to wake it up.
