Thread: what is the stud and bolt size on a t25 turbo?

I want to get all new studs to connect the o2 pipe to the turbo and need to know the stud size. I also need the bolt size used and the bolt size used for the manifold to the turbo.

thanks

I believe they are M8x1.25 for the manifold to the turbo and then the turbo to the jpipe. From there you have M10X1.50 for the three studs for the downpipe.

Thanks i want to order all new ones for my t25 so i have a leak proof turbo, which seems to always happen to me somewhere....... I am ordering these FRSport Turbo Outlet 8mm (1.25pitch) Stud and these to keep things nice and snug FRSport Turbo Outlet 8mm (1.25pitch) Locking Head Nut

Thanks
