Think I have an issue lol.
Right Lambda stopped working so hasn`t been driven since so today I thought sod it, and I took the Lambda out to fit a spare Bosch Lambda I had to see if it made any difference.
What I pulled out was shocking.
So gonna have to look inside the turbo now see if its done any damage, as the lambda is in a STUPID position before the turbo. So all those bits I`m gonna assume have been blown straight through the turbo, so gonna have to have a look.
GREAT!! lol.

Yeah, it's totally moronic to have a lambda PRE-turbo! What were Subaru thinking?! 
If it's for accuracy, then sack that! Rather have a slightly under-performing lambda sensor/ECU feedback system, than the ever potential threat of a knackered turbo...

Yeah. Well they placed the later lambdas in the downpipes on later cars, where it is now would be fine on a n/a car and that close it doesn`t have to be heated either, as most single wire lambdas aren`t as close to the head as the Subaru ones. Most heated Lambdas are a around 12inch + down stream as the exhaust gas flow is less disturbed.

Some have an EGT sensor there too.
Most likely damage is some minor blade damage to the exhaust wheel in the turbo. As it sounds like the turbo is still working it has not jammed it in one position (which is good) but it may have taken a tip off a blade or too. However if it had done that the turbo would be out of balance and would quickly sh*t itself. So, in summary - I think you have been very lucky !

Have you inspected your turbo exhaust wheel for damage?
The Lambda sensor is located before the turbo on all Subaru WRX/STi MY93-96 and MY01 onwards.
For the Lambda sensor to suffer the damage shown in your photograph I would suspect you have been running very weak.
The location of the Lambda sensor prior to the turbo has not been a big issue and the problem on your car is most likely due to a pre existing problem.
The Lambda is located there because obviously is warms up quicker and may be in the main due to emission control reasons. Moving it to the downpipe is a good move.

Same thing happened to a mate of mine with his old WRX. The lambda that failed was a Lucas universal jobbie, so probably not up to the temp. Will have to get the pipes off, and have a damn good look inside and then fit a new Lambda then see what she goes like. Tbh think its been like this since I had it, as in the advert it states
"currently running on a tdo5 turbo after the aps sr55 turbo started to smoke so isnt running its full potential at the mo"
so think that the lambda had failed already and that I should have checked before fitting the engine tbh. Because I have never driven the car before due to buying it with a dead engine, so what I think has happened since I have run it is that the lambda has finally given up the ghost, and with me not having driven It I`d have not felt anything wrong. Any ways will be phoning around tomorrow to get a new lambda, when that arrives exhaust off, and see whats what in the turbo.
Happy days.

Right Main dealers have Lambda on order £132.02 + VAT, will be there Thursday.
Will have to double check when I go up its the right one, then crack on Friday with swapping the downpipes, and checking the turbo.
They also said that Subaru putting parts up in price from Sept by 12% iirc, dunno how true this is.

Quick hijack!
Hi Guys, Will be finally replacing my turbo this weekend - have not looked at my lambda sensor as yet but if I find it to be fooked........I already have one from a 96 model spare that I could put on - will this be ok?? will it go into the existing position on the maifold or should I relocated to the decat downpipe?
Anything else I should know before embarking???
Sorry of the offspin..
I believe the hotside fins to be slightly worn on the turbo so after seeing this I think Id beta check the lambda too.
