'Ryuji'

Hey guys,

I recently installed a boost gauge on my FD and went on a test drive to see if it was boosting properly. During the run I did a WOT run on 3rd gear and everything seemed fine and read the standard boost of 10 PSI until I hit 4000-4500 ; after the gauge reads 0 PSI of boost up till redline. Could it be blown turbos ? I also noticed a little fluttering sound when I'm WOT around the 4500-redline rev range.

My car is pretty much stock; cat-back, Blitz BOV, HKS Turbo timer.

Go to the 3rd gen FAQ thread:

Scroll down to the T section for Turbo. Follow the links to the threads there. This is one of them:

That will lead you to troubleshooting procedures so you can understand what you need to do.

Hang in there and read up on it. There are various things that could cause lack of secondary turbo and you need work through the steps. I'm going through the same thing myself...
