As above , about to replace these bolts as the took a battering getting off.. The 2 bolts go through the down pipe into a threaded flange on the turbo..Looks like M12. anyone confirm? Pitch? Ta Nik

are they m12? I thought m10 but cant remember problably 1.5 pitch though

Im sure I have fired m12 through them

Thanks guys..I have the turbo on the bench...it def looks M12 .illl get the pitch gauge out . Just for the record ill try and post some photos of the opened turbo so it all makes sense.Nik

M12 by 1.25

i knew it was a fine pitch
