Re: Banjo bolt fitting for turbo coolant line
I got one from my coolant hose/parts place here in the UK - I think it is a metric thread. I am away until Friday so can't check immediately.
If you're struggling then I can send you the one I no longer need.
I have a some lines made up for the stock turbo that make life a bit easier - metal turbo flange welded onto pipe - braided if you're interested as well. (Oil and coolant)
