Hi,



This is my first post, but i have buyed a FD from year 93 but i have a problem with boost...



The car only start making boost after 4000rpm... and don't make more then 5 psi



Anyone with this problem?

Start with the simple things, like observing all the hoses, vacuum hoses, pipes. if you havent dont the vaccum line replacements then you should do something like that. either that or take it to a rotary specialist

check the actuator for the double throttle.. make sure that the vac source didnt pop off.... after that.. it can be 50 other things

Hi,



Thanks for your answer...



When i buy the car (3 days ago) the car makes 0 boost... then i force all actuators to move... because the car have been stopped for a long time.

Now the car makes 5 psi...



But the turbos on "fire" after i stop the car...this is normal on this car?

(i don't know the right word)



Tomorrow i will change some vacum lines...



If i remove the pipe from turbo to wastegate, the turbo don't make the max boost that is possible? i tryed this but is the same...



A hug

Hi again,



sorry for my many post...



I tested the actuator of double throutle manually... and i hear a noise of air go out near Pressure Chamber. But i don't have many light to if there are any pipe disconnected on solenoid. The noise are normal? I test it without the engine running.
