Hello –I need some help with where to place an O2 sensor (if what I want to do is even possible). I’m converting a Banks turbo kit to a blow thru deal and the engine will be used in a closed engine compartment, so basically I’m stuck using the water jacketed exhaust system. My only thought was to possibly remove some material from the flange in the pic below and install the sensor here (assuming I have room to do so). But this would put the sensor only a few inches away from the turbo. Is that too close for the sensor to work properly?
I talked to my engine builder and he didn’t think there would be a problem doing it this way. Then I talked to the guys at FiTech (I was thinking about using their kit) and they said that it wouldn’t work and that the sensor should be at least 12” away from the turbo due to extreme heat and pressure. So now I have conflicting advice and I do not know what to do. Regardless if I run the FiTech EFI kit or go with a carb, at the end of the day I want to have a working O2 sensor for peace of mind that my setup is tuned correctly. Now I just need a way to pull this off. What do you guys think?
