Im fabbing up my turbos now and alls i have left to figure out with my welding is the o2 sensor in KB Rancings kit he is selling i notice it is right after the manifold and right before the turbo on the pass. side


just use his knowledge and go with those locations ????

what are you guys running as far as turbo and o2 sensor locations before or after??

also where to put my wideband?


here is my setup

 

first O2 is close to the stock location on the DP. WB is right after my exhaust connection. Where is your radiator going to be on this???

 

from the looks of your kit, you could run tthe 02 on the down pipe as wj said. The wide band should go after the turbos for sure.

 

radiator is right behind the intercooler ..... mounts are getting powder coated ...... but will sit fairly close in front of the engine with an electric fan mounted.

wideband on the DP should be like ...... 12 inches from? 4 inches from??? thats kinda what i was looking for --- i am very new to turbos .... just liked the power and bought a set ......

i should have just bought a kit .......

since its twins should i run the o2's on the manifolds and the wideband on the dp? or all on the dp at different locations?

or doesnt it matter?

 

The 02s would be happier after the turbo. Where exactlly well depend on space, but you are going to want them somewhere before the trans area.

 

Since you are twins you stock o2 stuff can be before or after the turbo will not really matter.
Your widebands same thing.

Not sure about other widebands, but mine you can install anywhere in the system. But its not recommended to be any close to the end of the line then 18". Setting the sensor to close to a dump/outlet can cause false readings.

We did a before and after test with an old FJO dual channel wideband it there is a difference in the readings, not much but it is different.

 

On my kits, drives side is near stock location in the cross over, pass side is a few inches before the turbo and WB is about 6 inches after the turbo in the down pipe. Has worked just fine like that in my truck for almost 2 years now.
