Locking nuts - without the nylon
I need some nuts to bolt the turbo to the downpipe, it expands and contracts so much with extreme heat none of the nuts will stay on with even with
split washers.
Obviously can't use nylocks as they will melt, so is there anything else I can use?

Various options including using lockwire. Or even high temperature locktite.
But the best options are the special type of nuts that I used on mine.... but I've forgotten the damn name of them whilst typing this!!! lol
Soon as I remember I'll post again.
Or, ask Fozzie, as it was her that first told me about them! 
Cheers,
James

we've used nordlock washers on avoneer's turbo install in his mx5. seem to be doing well so far.
you can use all metal locking nuts like stover nuts but you might suffer the same issues. if you can get hold of aerotight nuts, they're
probably superior
how many do you need anyway? i think i might have a few spare pairs of nordlock washers if you want to give them a go

my company tends to use (what we call) Nedlock nuts, I think these are also the same as the stover nuts. They have the top of the nut deformed in to
pinch the thread. We have done vehicle life testing at Mira with loads of different nuts and we now use these as our standard, and have for many
years. We had poor results from the nordlock washers and the ones with the washer type thing attached on the top end.

putting my H&S pedant hat on companies now cannot sell yellow plated anything as it doesnt conform to RoHS. the yellow colour comes from
Hexavalent chrome which is a no-no
They have to use Trivalent chrome plating which is a silvery colour.
I only know this because I am the RoHS coordinator for my company which sells industrial control gear.

Manifold nuts? Usually copper coated steel nuts with the last thread crimped.
