Are there any other options other than drilling the turbine inlet flange (T25) to accomodate for the larger BEGI exhaust manifold 10mm studs? Like a 10mm to 8mm stud (I don't know the standard Garrett flange size, but I know they're smaller than 10mm)? The flange holes on my turbo seem pretty thin along the edges already.

Thanks

 

10 to 8mm stud would be useless. Also, that stud doesn't exist; I tried searching for one when I was trying to install my knock sensor. McMaster-Carr said they didn't have it and they wouldn't know where to get one, and as far as I'm concerned, if they don't have it, it doesn't exist. Even if it did, it would just break at the 8mm section. Drill the turbo, or better yet, take off the turbine housing, mail it to Corky, and have him drill it.

Have a shop drill them out for you, trust me its not worth the hassle if you ever take off the turbo and the 8mm stud breaks or the adapter ^ breaks.

 

I wouldn't even take it to a shop.. they are shallow through holes. Just take the housing off and do it yourself. will save you $40.

 

or that, since I dont have a bore machine, didn't want to risk ******* up my bits or my turbo I gave it to my mechanic. Free for me.

 

I've used a hand drill for much more precise things than drilling out mounting flange through holes...
