Help~ my little FD
i just bought a 94 FD recently, engine already swap with 99 13B-TT,
1)the situation is, when i kick the gas pedal hard(although till 7-8000rpm) the boost meter will only up to 0.5bar(7-8psi), and really lack of power...
and if i kick the gas pedal smoothly till 7-8000rpm the boost meter will up to 0.7bar(10-11psi)...
check with technician and found out one of the one-way valve has broken and didnt connect, and cause turbo "leak".... should be turbo vaccum.. and replace it...
second situation, now when i kick the gas pedal hard(although till 7-8000rpm) the boost meter also will only up to 0.5bar(7-8psi), and really lack of power...
and if i kick the gas pedal smoothly till 7-8000rpm the boost meter now will up to 0.8bar(12-13psi)... the stock turbo is back....
and why? any idea?....
2)when i hit the brake pedal hard, the car didnt stop in a straight line, it keep braking like snake.... and have to grab the steering hard.. or will be very dangerous...
the tech say something like my steering rack and the boost there got problem, have two add more two boost at the steering there... anyone can tell me about that?
3)when i brake... there's a funny sound coming from right hand rear wheel, "crek.. crek.. crek... crek...." when the tyre spin fast and brake the the sound come more rapidly... wat is that?
the tech check and say not the disc brake problem... is a "stick things" joining the lower arm of rear wheel there making the noise... and have to change the stick, and the tech say that stick is use for alignment one... what is that?
Very appreciated if anyone can help!!! newbie here... Thanx in advance!!!:

1) Possibly loose vacuum hoses, possibly sticking solenoids, possibly worth testing the other check valves.
2) The braking problem sounds like a stuck caliper or something else that causes one wheel to grab much harder than the others. You definitely want to fix this problem first above all others.
3) Sounds like he's talking about the rear toe control link. You can buy new bushings from Mazda or buy an aftermarket set, the cost is about the same. While you're working in the rear suspension also have the tech look for worn out pillowballs (spherical bearings).
