maybemark Posted September 2, 2008 Share Posted September 2, 2008 I have an 82 280zx turbo that i am upgrating to a holset hy35. I wondered if anyone would know what the stock oil pressure to the stock turbo might be. Also, does anyone know what pressure i should be running to the hy35. I have several different banjo bolts I can use with differenet size hole openings, I just need to know which one would be the best one.

WizardBlack Posted September 5, 2008 Share Posted September 5, 2008 Might need to check a Cummins forum for that info. Being that they are oil cooled, my thought is they don't want a restricted feed like water cooled ball bearing turbos. Mine doesn't use a banjo, but rather a screw-in fitting to convert to -4AN and it very clearly drops oil pressure. Quote Link to comment Share on other sites More sharing options...
