Here is the scenario:

- No boost on neutral on WOT (I understand it should be somewhere near 4 PSI).
- 6 PSI max on any gear on WOT, with no apparent transition between turbos.
- All the major boost hoses were verified ok.
- Tested car with no actuator hoses and there was no boost increase.

The car is a stock 93 RX7.

Any help will be appreciated. I'll hate to sell the damn car without testing it to its full potential!!

 

How can I increase the boost on the primary turbo without adding any other hardware? Is there any valve or rod that I could adjust on the turbos?

 

i had this problem, my intercooler piping had a leak, I would check the lower intercooler elbow, make sure its not loose.

 

I had the same problem.
I also tried to fix it by replacing my pills with valves.
Finally I replaced the hoses and cant believe I waited so long 10-7-10.
I could probably adjust the vales and improve a bit
but Im just enjoying the way it drives compared to before.
Just replace the hoses you wont regret it.

 

Any other suggestion will be appreciated.
