Oil Feed Adapter 0,9mm Restrictor GT-R bis GT37 - SS Oil Supply Adapter with 0,9mm Restrictor Necessary with Oil pressures over 3bar The Oil Restrictor is mandatory for every ball bearing Turbochargers GT25 up to GT35 with Engines with more than 3bar Oil pressure at full throttle. Without the Restrictor a bearing damage will happen soon! The adapter has at Turbocharger Side a special M11x1 thread and a Dash 4 / 4 AN thread for construction with our self building hydraulic fittings. For pressure relief is a 0,9mm drilling in the Adapter. For safety reasons we recommend our Oil Supply Filter which filtrates smallest particles and prevents an obstruction of the Adapter.
