R33 Exhaust Manifold Studs

[WogsRus]

So i am about to pull of the manifold first thing in the morning, but need to know.

WHAT Are the stock size of the studs, are they M10*1.5 or M10*1.25. Are they M10 both ends, because as i found out today, the ones form the manifold to the turbo have TWO different threads.

HELP, need anwser ASAP, manifold comingof tomorrow, but i need to buy the parts first.

fairly confident they are metric fine. m10 X 1.25. Which is rather stupid in the case of alloy heads as it should be a coarse thread, so its less likely to strip out.

Use a thread pitch guage and find out exactly incase there is doubt.

yeah well the thread i snapped is M10*1.5 so hummm. i guess i'll have to pull them out and see.

Ok just to clear it up, the studa ARE M10*1.25
