P0243 - Turbocharger Wastegate Solenoid 1 -you don't need to worry about that, boost bypass for s/c is gone
P1653 - Oil Level Lamp Control Circuit- maybe didn't get connected properly after installing turbo oil feed there?
P1133 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1- I'd say either the o2 sensor(Bank1) is bad/not plugged in properly or a issue with the pigtail from the wire harness to the o2 sensor
