im going to use the stock dsm t25 and o2 sensor housing, but my question is do i need to run my stock b18c1 o2 too the dsm o2 housing or just plug it up and keep my o2 on the down pipe

 

CAN ANYONE HELP!!!! where do you put your stock o2 sensor on turbo setups thank you for any help im NEW here, sorry if im not the smartest but there is not a web site or forum that answers my desired setup ques. agian thanks

 

i would just plug it up and keep o2 on downpipe...sitting that close to the turbo might have some heat soak problems

 

what is heatsoaking?
And would kepping my o2 sensor on my downpipe cause a bad reading for my AFR gauge, or a "TO LATE READING" my engine is blown

The DSM's don't seem to have problems with the O2 there, and neither does my car. It's right after the turbo in the DP.
