I need 4 studs to bolt the Turbo to the M30 Turbo Manifold, What size are the studs? (they look a little bigger than the stock exhaust studs)

Thanks!,

I'm pretty sure the TCD manifold uses your stock 8mm studs... no need to replace them.

The 745i manifold on the other hand is different

Im going to use the stock studs to mount the Manifold to the engine.

But the 4 bolts that hold the Turbine Housing to the Manifold is what I need.

Tthe stock exhaust manifold studs are too small, its some size a little bigger.

Thanks,
