A wastegate assembly (200) for a turbocharger (101) or the like is provided having a support plate (300), an actuator (275), a linkage (250) operably connected to the actuator (275), and a valve plate (225) operably connected to the linkage (250). The linkage (250) translates actuation of the actuat
A wastegate assembly (200) for a turbocharger (101) or the like is provided having a support plate (300), an actuator (275), a linkage (250) operably connected to the actuator (275), and a valve plate (225) operably connected to the linkage (250). The linkage (250) translates actuation of the actuator (275) to movement of the valve plate (225) thereby sealing or unsealing the bypass outlet (500). The actuator (275), linkage (250) and valve plate (225) can be pre-assembled to the support plate (300) prior to the support plate (300) being connected to the turbine housing (102). The actuator (275), linkage (250) and valve plate (225) can be calibrated prior to the wastegate assembly (200) being connected to the turbine housing (102). The bypass outlet (500) can be machined via access provided by the wastegate port (400).

1. A method of manufacturing a turbocharger (101), the method comprising: forming a bypass outlet (500) and a wastegate port (400) in a turbine housing (102);machining the bypass outlet (500) by accessing the bypass outlet (500) through the wastegate port (400);pre-assembling a support plate (300),
1. A method of manufacturing a turbocharger (101), the method comprising: forming a bypass outlet (500) and a wastegate port (400) in a turbine housing (102);machining the bypass outlet (500) by accessing the bypass outlet (500) through the wastegate port (400);pre-assembling a support plate (300), an actuator (275), a linkage (250) operably connected to the actuator (275), and a valve plate (225) operably connected to the linkage (250) to form a wastegate assembly (200);positioning the valve plate (225) through the wastegate port (400); andconnecting the support plate (300) to the turbine housing (102) thereby mounting the wastegate assembly (200) to the turbine housing (102), wherein the linkage (250) translates actuation of the actuator (275) to movement of the valve plate (225) thereby sealing or unsealing the bypass outlet (500). 2. The method of claim 1, wherein the wastegate port (400) is formed on a first side of the turbine housing (102) and the bypass outlet (500) is formed on a second side of the turbine housing (102) adjacent to the first side. 3. The method of claim 1, wherein the support plate (300) has first and second portions (310, 320) that are at an angle to each other. 4. The method of claim 1, wherein the actuator (275), linkage (250) and valve plate (225) are connected only to the support plate (300). 5. The method of claim 1, further comprising calibrating the actuator (275), linkage (250) and valve plate (225) prior to connecting the support plate (300) to the turbine housing (102). 6. The method of claim 1, wherein the actuator (275) is electronic. 7. A method of manufacturing a turbocharger (101), the turbocharger (101) including a turbine housing (102) having a turbine inlet (1000), a bypass outlet (500) and a wastegate port (400), the method comprising: machining the bypass outlet (500) by accessing the bypass outlet (500) through the wastegate port (400). 8. The method of claim 7, wherein the wastegate port (400) is formed on a first side of the turbine housing (102) and the bypass outlet (500) is formed on a second side of the turbine housing (102) adjacent to the first side. 9. The method of claim 7, further comprising: pre-assembling a support plate (300), an actuator (275), a linkage (250) operably connected to the actuator (275), and a valve plate (225) operably connected to the linkage (250) to form a wastegate assembly (200);positioning the valve plate (225) through the wastegate port (400); andconnecting the support plate (300) to the turbine housing (102) thereby mounting the wastegate assembly (200) to the turbine housing (102), wherein the linkage (250) translates actuation of the actuator (275) to movement of the valve plate (225) thereby sealing or unsealing the bypass outlet (500). 10. The method of claim 9, wherein the support plate (300) has first and second portions (310, 320) that are at an angle to each other. 11. The method of claim 9, wherein the actuator (275), linkage (250) and valve plate (225) are connected only to the support plate (300). 12. The method of claim 9, further comprising calibrating the actuator (275), linkage (250) and valve plate (225) prior to connecting the support plate (300) to the turbine housing (102). 13. The method of claim 9, wherein the actuator (275) is electronic.
