I have a wideband sensor and gauge kit on its way and will need to have a bung installed. Is there an agreed upon best location? I noticed the bung for the stock o2 sensor for gsl-se is right on the header. Is that an appropriate spot for a wideband?

 

AEM says 18in from the port. That's what I always do =/

 

Somewhere next to the gearbox. Keep it somewhere between horizontal and vertical so its not subject to pooling fluid, ie weld the bung on the top half of the pipe. You can run the lead up through the shifter boot.

 

Keep it further away from the engine than the stock location. The stock one is a narrow band and requires exhaust heat to make it function. The wideband has its own heater and can get damaged if too close to the exhaust port.

I put a bung down near the gearbox where it's horizontal, angled 10 degrees up like the instructions recommend.

 

I have been using one for two months now and also installed the following
Innovate Motorsports 3729 Heat-Sink Bung Extender HBX-1

 

Pretty sure they recommend a minimum of 10* up from horizontal.

 

Ah yes, I think they do.

 

Thanks y'all!

 

I installed a pair of the heatsink style bungs at the end of the Racing Beat header. I cut away a small portion of a heat shield to avoid the wires getting cut but otherwise it was a nice fit with plenty of clearance. Takes a minute or so for them to heat up. If running the stock Nikki, the rear rotor will go back into heater mode occasionally on deceleration as the shutter valve opens and closes.

 

 

If its an LSU 4.2 on a rotary, the trash can. If its an LSU 4.9 12-18 inches from the ports, so usually right after the manifold/headers.

 

vgonzalez, that looks like an MG.

 

I was going to say the same thing. I keep looking at mine in the shop and thinking...hm...rotary? But then I remember that I have enough half built projects and that I'd like to vintage race it one day.
