Hi guys, Just need a confirmation on the turbo to dump stud size for the stock rb25 turbo. Is it M10 x 1.25? Cheers

Guys need help confused my rear left wheel studs on my r33 gtst are broken now wheel studs from factory are 43.9 mm, looking up on ebay for some new ones but there like 73mm and 65 mm in length if i buy these will my wheel nuts even fit back on, when i put the Tyre on

Hey guys, I am re-assembling my head and I noticed when removing the arp head studs, a couple of the nuts had bottomed out on the thread. i was wondering if anyone knew the height required for the threads to not bottom out. From my measurements; -Block face to nut 70mm (both wound in all the way by hand) -Washer 3mm -Factory head gasket 1mm so this means if the height of the cylinder head face to the washer face Is less than 66mm the nut is not actually compressing the head down. Factoring in machining of the head I know there will be differences but does anyone know the factory height of the head? If it’s something much lower like 65 then I know it was just the stud not wound in properly but just want to make sure I’m getting proper torque as I have read some people double up on the washers
