in the process of pulling my down pipe i stripped the studs and in getting those out stripped the threads in the actual turbo... any suggestions on pulling turbos to retap the hole ? I have never done it before Any advice would be greatly appreciated

other then unbolting the turbos from the manifold, u must undo
the oil feed line
2 coolant lines
2 oil return lines
kind of a pain in the *** to remove, u need to access these components from the engine bay and under the car. good luck

You sure the threads in the cast-iron are shot? I have found they are usually fine, and if I use an M10-1.5mm tap I can clean them out again.

the threads may not be shot but there maybe some thread from the stud left in them either way i can't put another bolt in there and i can't fit a tap or a drill down there

I would go ahead and remove the turbos so you can get a better look and repair it properly.

This same thing happened to me. When i took my turbos off on the engine stand all of the studs came out with the nuts.... then the downpipe nuts also proved to be a problematic.


After the seized nuts/studs soaked in PB blaster for a week the nuts came off the studs easily.


One of my downpipe studs was soooo seized that it took half of the threads out with it, luckily i was able to use another stud and double nut it from the other side to 'repair' the threads.. well half of them anyways. I installed the new stud with a lot of red loctite, so hopefully it will last until i go single!



I would either try to retap the original threads as stated above, or just tap a slightly larger thread.

has anyone been able to retap the hole while the turbos were on the car?

If you do choose to take off your turbos I’d suggest you label things as you go. It just makes reinstalling them a lot easier. Cheers
