On tue. the 21st, my 93 rx7 goes to the doctor. Heres the problem my first turbo is only putting out a steady 5psi. The 2nd turbo is fine, putting out 11-12psi. Ive replaced the turbo intake hoses, checked the bov's, check valve, and from what I can see I've inspected the vaccum lines. the car has 47,000 miles on it. The boost guage reads that I have 14 something of vaccum. So for you guy's who think you know alot about these cars, why dont you bet what the prob. is. I will post the prob. after I find out whats wrong.
Oh yeah the only mod on my car is the pettit cold air induction.

 

These bets assume the inforamtion you said you checked were okay adn no physical damage to turbo.

CRV malfunction(and related selnoid)

TPC malfucntion (and related selenoid)

TCA amlfucntion ("")

or the guy who had your car before did a nonsequential mod adn everythign is kosher
