Question Help

Does anyone know anybody at Greddy. My exhaust manifold needs replaced.
When installing the turbo to the exhaust manifold 1 of the bolts sheared. My guess at this point is the kit was sent with bolts that were too long. I come to this conclution because I have now, after dissasmeble, installed the bolts and there is more space left between the washer and the turbo manifold.
Anyway I replaced the sheered bolt with a Grade 8 hex head bolt. After 100 miles , that bolt was ripped out and stripped the threads on the exhaust manifold.
I have two choices, Hope Greddy will replace the manifold, or have the stripped hole re threaded. I have someone where I work that can do that,
Any Info is greatly appreciated.

Take it to a local engine rebuilder/machine shop and have him drill and tap them all to 3/8". He'll have to also enlarge the holes on the turbo flange. Buy exhaust studs and use those. You'll likely have to trim the studs down a bit to make everything fit. I'll go take a quick shot of my manifold with turbo installed.

I think 3/8" is about as big as you'll be able to go and still get nuts on the studs.

1) Clearance is pretty tight.
2) 3/8" is significantly larger than 8mm, and easier to source.
3) Swanky wastegate spring with turnbuckle.

If coarse thread was the best thing you ever did, imagine what fine thread would've been like!

Default Manifold

I went an purchases a heli coli kit at the local car quest . I used the drill press at the airline maint hanger and then tapped the hole. The kit came with a tool to insert the heli coil (new threads). I just used the same M8 x 1.25 because I had already done this b4 reading todays posts. Thx for the help.
