If you stand in front of my rx7 , I have the arrows pointing to the right on one, then up towards manifold on the other two .. Jw if that is right or if I should switch around. I posted a picture

 

Use the image on the following page which has the check valve orientation shown:

Vacuum Hose Replacement

 

Yep. Each check valve is kind of shaped like an arrow, use the vacuum hose guide to install them.

Looking at this diagram it looks like the arrows are going left .... <l ... I have them installed l> .. Should I switch around ? Will car run with valves in wrong way ?

 

So on this valve ... I have the arrow pointing |> .. Is that correct, that how it was when I took the old valve.. Diagram looks like arrow should be <| ..

 

It might just be routed differently than the diagram, follow the hose and see where it leads to.
It seems like its coming from the rats nest into the intake manifold which is correct.

 

So since I pointed the arrows as in picture but now I'm only getting 10lbs of boost in 3,4 th gear ... Any ideas ? Maybe one of valves wrong ?

 

So since I pointed the arrows in direction of vaccum lines on diagram I am only getting full boost at partial throttle .. When I shift fast no boost... But when I ease into gear boost.... Any ideas ?

 

The picture you posted up of the check valve coming off the Y-pipe, that is oriented in the correct direction.

Then likely your problem was never with the check valves to begin with? Have you gone through the Troubleshooting guide yet?

Troubleshooting

 

The issue I had before was only getting only 2lbs of boost when fully warm.. Now I'm getting 10lbs boost partial throttle , but not when I go full throttle ... So I think the check valves helped somewhat ... When I bought the car and I changed the check valves they were pointing in the opposite direction .. I changed them to point the other way and now I get boost partial throttle ... I don't think it's turbo lag ..

 

I think I narrowed it down to my secondaries now working because when I punch it over 4k rpms no boost

 

Not working *

 

I just had this problem the other day when I was only getting secondary boost in 3rd and above where in 1st and 2nd I was only getting 10psi under 4500rpm.. I replaced all the vacuum pipes which didn't help, I then replaced my turbo control solenoid valve and that seemed to solve the problem..

 

Where is this solenoid located ? I will look at diagram later to see if I can find

 

It's under the manifold behind the waste-gate and pre-control valves. If you take off the UIM you'll be able to reach it. It's bolted to LIM. https://www.rx7club.com/attachments/...m-solenoid-jpg
