R32 Gtr O2 Sensor Inserts

[LotusGTR]

Any ideas on where to source these? I know you can do without the O2 sensors but have briefly discussed with my tuner and have decided I want to use them.

Attached is a picture of the bigger R34 apeture into which I assume you screw & weld the smaller insert to suit the R32 sensors.

Thanks.

Some have used 34 o2 sensors successfully even though they are zirconia (not titania like the 32 ones, and electrically different). My xforce dumps came with an adapter that bolted in, but it was hopeless as the sensor didn't protrude into the flow path properly. I took my xforces to an exhaust shop and had them cut off the 34 mounting and weld the 32 mount adapter into a sensible position.

This is what the unmodified xforce + adapter looked like. I cant imagine the o2 would work at all like that. In the stock dumps it protrudes well into the flow path.

So, here is a bung I got from my tuner. I need another and also to know what diameter to drill it and to what pitch, so as to fit the R32 sensor. Or, any ideas where to buy these off the shelf with the hole drilled / tapped? I'm told these should be available on ebay but I cannot find. I understand that the Silvia guys had early late / big small model O2 sensors so should be available?

Any further thoughts?
