ok, I have the engine out, installing the turbo's, etc. but,

when I try to install the a/f sensor, on the drivers side, it seems to touch or come VERY close to the exhaust manifold??

any help???

 

difficult to see in the pic, and i dont remember unless im looking at my car..but isnt the o2 sensor supposed to come in from the outside..is that downpipe on the wrong way? or on the wrong side?

 

we quadrupled checked...put both on each side, rotated, double checked the turbo's, etc

the passangers side is perfect

 

i just checked through my entire library of pics, none of them showed the 02 sensors in the downpipes, sorry

i'll keep looking

TODD

 

i just saw a couple of other pics on the web & some how it looks like the bung on that pipe is welded over closer to the top than most?
as opposed to being off to the side

 

where did you get your kit..is it the 3 bolt or 4 bolt flange on the downpipe...(2 production runs with the greddy tt)

EDIT: I see it is the 3 bolt flange, newer kit...

may i offer an additional suggestion, safety wire the hardware around the turbo to downpipe connection and the manifold to turbo connection...i have had these bolts and nuts unscrew and fall off (from the repetitive extreme heating and cooling cycles)

safety wire: drill tiny holes through the head sof the bolts, or the threads of the studs, run a wire through the holes (all 3 locations) and twist the wire around itself, forming a ring that goes through each one of the bolts/studs...this is a common practice on aircraft

 

im a little bit slow more info or pics? i know you explained in pretty good detail already but.. i just dont see it in my head
