I'm about to weld on the O2 sensor ring. I'm going to have the sensor in the top of the exhaust about 5" from the turbo. I need to make sure I have enough room to get the sensor in. It looks like I have about 2-1/2" if I locate it straight up.

Here's a (lousy) pic of mine, but it's wrapped in some Aeroquip heat wrap. It's probably about 5''-6'' away from the turbo.

It sounds like you are going to weld it on before you install the motor? I would wait until it's installed if you can, just to make sure.

I've got the engine in and the bumper on, I just don't have the sensor. I checked the sensor on my R1100S and it's sticks up about 3-1/2". If that's the norm, I'm going to have to angle it back to clear the bodywork and the engine. I was planning to put a steel bumper under the fiberglass C2 facade bumper, but this might prevent that. I'm planning to use the Innovate wide band system.

That's what's hiding under the heat wrap. I just wanted to protect all of it from the heat and went ahead and did the same for the unit in the engine bay.

3 1/2 sounds about right. I wanted to make sure I didn't have a kinked wire or one running at a funny angle.

OK, I'm angling it back. Hopefully I'll still have room for a bumper. If not, I'll just have to make sure nobody gets near my bumper. That shouldn't be a problem with 500+ rwhp.

David, I agree you should angle it back about 20-25 deg to get room for the sensor. I used the Innovate wide band system on my standard muffler/standard bumper in the same position as you and I had to angle it back just a bit to get a good fit.

I have mounted straight up. Most of the time it is on a aftermarket bumper. You can reach it especially with the stinger on there. There is clearance up top. Depending on the setup you may simply need to remove the bumper.
