hi.

when having my 3" DP wrapped today, I noticed one nut missing that mates from the bellmouth flange to the turbo.
where can I get this nut that will fit the bolt from the turbo, its got a thread pattern different from most bolts.

anyone know size of nut I will require ?

all other nuts are fitted but just this single nut isn't, whether it was missed purposely or by accident when I was having my downpipe fitted, I will never know, at the time I didn't step under the ramp to carry out a thorough inspection, but with hindsight I wished I had.
any suggestions. ?

 

I believe they are m12 x 1.25

I wouldn't worry too much though as it could have happened by accident? When I fitted a new turbo I done all of the nuts up tight but when mapping they kept coming undone. So it may have been fitted bur just undone itself when driving it?

 

Yeah my bad, they are m10, think I was still half asleep

 

but one missing nut from the flange to the turbo, may cause leak or boost issues, is it imperative that this nut is put back on. the car has no power loss and drives fine. but its playing on my mind as its near to the turbo.

 

The std nuts that come with the turbo should not come loose and more times than not the one on the top nearest the passenger side can seize & need to be cut off. I always keep spares of these nuts as you never know ,but if you want some try the link below:

thanks, that was helpful. but what if I just purchase the nut size
10M X 1.25 FINE PITCH, will this do the job. as I only need one nut.
