Having a boost issue and i've run out of ideas of what could be causing it.
Basically the car will only reach 11 PSI of boost no matter what i've tried. Please note all turbo kit parts are brand new.
So far i've:
- Eliminated the wastegate being the issue (ran boost to the top port of the wastegate to keep it shut and still only achieved 11 PSI - should have spiked out of control - also done on dyno with visual of wastegate to verify it isn't opening).
- Checked for any boost leaks using a tester.
- Examined Intercooler & piping for any restrictions.
- Checked for any exhaust leaks from head to turbo - fitted brand new gaskets and bolts to make sure of a good fit
Turbo is a T3/TO4B Turbonetics and should be able to easily achieve more boost.
On saturday we are going to take off the exhaust system and see if its that but causing a restriction but i'm doubtful as its a 5zigen 2.5" system and should be spot on.
After that i'm stumped.
