Hi,

Got a Bosch wideband O2 Sensor with the LC-1 kit. My car has the stock 'pseudo' wideband sensor in the up-pipe and a narrowband after the cat on the back.

Since the cats will interfere with the wideband, I'm thinking of swapping out the front one, however the manual advises against installing the sensor before a turbo due to the pressure on the exhaust inlet.

Given that Subaru already put an O2 sensor right there does anyone know whether or not the LC-1 can go there safely? The idea is that I could then connect the narrowband wire back to the ECU, assuming that the calibration holds..
