So I was driving with my buddy the other night and wanted to shap him why rx7s are awesome (it's stock except for cat back and cai) and I was in secOd gear going about 40km and only say 0.2BAR on my gauge and it would maybe go up to 0.5bar. It seemed to only be the second turbo that wasnt boosting right, I could feel it die off. So in disappointment I drove home. This morning I was driving and it wouldn't boost in second gear, so I drove normally until 4th gear then down shifted to 3rd and got full 0.9 at o boost. I I thought I'd try boosting in every gear and saw and felt full boost. It was like my car didn't want to show him what full boost was like. The funny thing is this happened as soon as she rolled to 190000km. Now it's 190036km

 

Check the boost/vaccum box in-front of the boost solenoids. I can't remember exactly what the box is called. Make sure the hoses are all connected to the box. One of mine got disconnected and primary boost was fine, but secondary boost was kind of odd.

 

Which boost vaccum box are you referring to? I am having the same problem.

 

Are you referring to the pressure chamber?

 

I don't remember what it is called. It is directly in front on the boost solenoids and the intake manifold.

 

I believe he means the pressure chamber , But that is very strange ,

Also to the OP do you have the original cats?

 

check your CRV and CCV solenoids. It might be sticking.
