I need to order some stainless bolts to hold the turbo on.
I have a T4 flanged turbo that has an adapter plate (t4-ct26 manifold) but i don't have the bolts/nuts or adapter plate for it at my shop to size the holes. What size bolt, thread pitch are normally used?

If i remember correctly its a 12mm or 14mm...

Thanks

The stock stud thread is M10x1.25...the stud is 47mm long. Threaded 15mm on the manifold side, 17mm on the turbo flange side.
