A couple of questions for rik when fitting, im using a clio 172 manifold to make a custom manifold and would be intrested to know if there is much difference in the port sizes between the standard and dbilas manifolds? and how much difference is there between the dbilas and vaux gasket?
spoke to the mechanic it was just a nut he had lying around - apparently designed for turbo manifold (different metal to normal - more heat resistant) ????????????????
not sure what the std ones are, but you shouldn't use steel for anything ove 350 C
You can normally get away with using A2-70 stainless, but if not then you'll need A-286 nickle which is expensive as it's v hard to machine.
Saying that we're now recomending inconel studs for modern diesel turbo as the gas temps are getting so high.
