Stripping down the unknown turbo in my mates 2wd saff and 2 of the turbo to manifold studs snap, managed to get one out with a stud extractor but the other isn't going any where, its "waisted" down to less than 6mm so the stud extractor wont grip it any more, tried heat and a vice grips but that just snapped it off...

Then 3 of the 6 bolts that hold the turbine housing on snapped, whilst drilling a pilot hole in one the bit snapped and is now jammed in there. Got a hole drilled in another and then the "hardened steel" screw extractor snapped in it....

Is the turbine housing scrap...???

Can you not take it a specialist engineers and see what very can do with it.

I think a spark eroder will remove pretty much anything if you know of someone with one? I had the same prob on the 'trousers' part of my manifold and they got it out.

A spark eroder would certainly do it, down to 1/4mm size hole!!

Mine Was Like That Before I Touched It,it Came Undone Really Easy Which Made Me Suspicious.i Heard Of Somebody Having Their Engine Wrecked By The Stud Pulling Out Of The Head So I Was Really Wary When Tightening It Up.i Dont Have A Special Engine But It Would Really Annoy Me Having To Rebuild It Because Of That Happening.least Thats 1 Thing Sorted,just Hope The New Sensor Arrives Tomorrow So I Can Take It Out To See If Everything I Have Done Is Ok.ordered It On Monday From P.j Motorsport And Still No Sign Of It!
