Hopefully this helps future JDM Mini owners with the cat temp sensor. I really wanted to try and get the sensor out unharmed but that didn't happen. Now I have a cat deleted SPI with the sensor cut and wires connected and taped off. Never have to worry about it again.

Why don't you remove the sensor and heat it up with a blow torch to see if a light in the dash lights up. Post a picture of your dash.

#1 is the sensor just after cat
#2 is a wider view of sensor showing wire going up and over cat via heatshield
#3 shows the wire continuing to left side front foot area
#4 shows the wire going into the car
#5 is a very bad picture of the O2 sensor on the header where it should be.

they assured me that they had done this on many other minis before.
No check engine light came on either
if everything seems under control,. then you're not going fast enough

Post a picture of what you have inside and underneath the car.

Mostly I don't want to cut the wire without knowing what will happen. I want to unplug it as a test first.

Just a though, I have been rebuilding a bunch of DAM 5626 trannys this year and stripped my fifth this week. To my surprise this one was under a 998. The third motion shaft double ball bearing had fractured ball spacers, worn third motion shaft spigot and lay shaft. And for the fifth time the diff. ball bearing fell off the diff cage. Shift forks and synchros worn but the spider gears and diff. pin not so bad. I have been buying cross pin diffs. and like them for a rebuild. The SPI is getting is getting a Quaife posi as well as REM and Cryo treatment for the gears. I have had good results reducing SC/CR tranny and drop gear noise with REM excited to see how it works on std gears.
The reason I mention tranny is three of the trannys suffered complete failure and were in SPI/MPI cars. To make it more fun they were all AC cars as well. Steve (CTR)
I would love to keep this car mostly stock and find a decent shell I can swap a Honda K20 into. But if my auto decides to go, then I will swap this car. So for now I am not looking for high performance, just a little more pep.
Thanks again everyone.
As for the CAT, I did not put one on mine when I put the SPI in.

Removing it certainly gets rid of extra connections that can leak.

AFAIK it was only used on the Japanese market Mini's for possible catalytic converter overheating issues (probably Japanese regulations) and has nothing to do with the running of the vehicle.
