I know it has to or should be placed closet to the cat as possible, I am more looking for at what position and distance from the rear flange you have yours placed.

I guess the best way to decribe it would be from looking rear of DP to front, using clock locations, also how far is yours placed from the flange? I was looking underneath and it seems like it will have to be standing almost straight up about the 11 o'clock postion, and about 4" from the flange, about 1/2" away from the chassis bracket.

Pics would be nice as well!

 

i dont have an FD so no specifics but:

locate sensor with 15deg to either side of vertical (reduces chance of condensation causing stresses and possibly breaking sensor)

space far from turbo to reduce temp flucuations

I know that, I was looking for specifics, thanks for the reply though.

 

Given the desire to keep the sensor vertical, there are few places to choose from, I ended up selecting the location in front of the cats were it has the most room between the tranny and the body tunnel.

It is best described as being right where the front cat heatshield mounts are located.

 

Sorry , but I got rid of all that factory stuff , went single turbo 3.5" pipe right off turbo O2 sensor about 18" back, magna flow 3.5 in 3.5 out, N1 3.5 at hte tip works for me.
