Hi all,
Thought i would share with everyone the results of my boost gauge installation.
Installed a 52mm Speco boost gauge to my d22 2.5
First i drilled and tapped a thread into my inlet manifold just below intercooler pipe. (Was extremely simple to do even for my first time)
I know some people are installing them down between the turbo and waste gate however id rather see what psi im getting in my manifold than what the turbo is pushing straight out.
Plumbed it all up and gave it a test run.
Worked excellent and is pushing 16psi at max (Completely stock engine and exhaust)
However on idle the needle bounced around quite alot and when i reached 15psi the gauge had a loud rattle. So did some research with my mate google and found out this is very common on diesel engines.
And the fix = unscrew the vacume hose of the back of the gauge, and place a small piece of cotton wool off an ear bud in the fitting and put it all back together. Still getting correct readings but no needle bounce or rattle.
Job done.
Its probably been covered before but hope this helps some one else.
Cheers
