Has anyone done a turbo leak back test on a 20 vt. I don't think I have a problem other than car is a little sluggish to accelerate but once going it runs well.
I have made up a leak back tester to fit the air intake pipe after it is removed from the MAF meter but I need to know what other pipes I may need to remove before forcing air into the intake system. I believe I will need to remove and block off the hole left after removing the fitting going to the engine breather but am not sure what the two smaller pipes just after this actually do ( they seem to go behind a heat shield but unsure as to what they do ). What kind of air pressure figure am I looking at putting into the intake system safely.
