Converting to single turbo on my RB26 and utilising an existing single turbo manifold from my RB25 that has both RB25 and 26 stud pattern.
However, RB20/25/30 is all M10 exhaust manifold studs and RB26 is M8 which leads to lots of slop on the exhaust manifold when fitting to the head.
Is it common to change to M10 exhaust studs when going single turbo RB26? Or even use some kind of stepped stud? Or people are happy to have some slop when installing the manifold.
Have searched as i thought it may be a common problem however finding no info online about it at all.
any help appreciated, thanks.
