where abouts on the top of the turbo does the lambda go? ive just bought another t3 but it dosent have the hole for the lambda i need to drill and tap it but i cant remember whereabouts it goes help needed asap please pics aswell if possible.

 

i'd rather stick it in the downpipe than drill the turbo personally

 

i thought it went into the back of the turbo, wastegate, just before the downpipe. i wouldnt actually be drilling into the turbo i wouldnt even attempt that.

 

Position is not crucial, so long as it gets HOT, so downpipe is fine.

if using d/p nearer the turbo the better!
