T4 and Tial 38mm fasteners (1 Viewer)

Does anyone know what size fasteners are used when bolting a T4 flanged Turbo and a Tial 38mm waste gate to the manifold.

I bought the gaskets and they seem to be made for a 10mm bolt. But I also found some pre-made flanges that where drilled and tapped for 8mm. Just want to be sure before I go any further.

I used the toyota exhaust manifold studs and nuts to bolt my t4 to my home made turbo manifold. these studs are the perfect size and come with those cool lock nuts. no problems with them yet and they stay tight. put a nut on both sides of the stud so you can adjust stud legth for your flange thickness

my cheap wastegate uses 8mm bolts. this cheap ebay tial 38mm knockoff has worked great
