ok, i just did the "useless fuse box relocation" on my car and to my surprise everything worked, puts a little more confidence in me to tackle some more extreme jobs.

i also just installed the banzai block off plate kit, but not the DT plate so i still have that.

so now i'm just looking under the hood of my car, which is essentially stock (with a JDM engine, no EGRV or solenoid) and i'm just looking for stuff that i can get rid of that just doesn't need to be there.

i'm looking at the pressure and vacuum chambers right now, do those actually serve a purpose? they're just empty boxes of air and will eventually lead to wherever.

also, i want to relocate my vacuum solenoids "somewhere" b/c under the UIM is just not good so i might as well do the vacuum hose job at the same time, but which solenoids can i get rid of considering i don't have the ACV? i want to keep the sequential system as well.

for a moment i thought about removing the ABS and moving that solenoids there but.....you know, no ABS.....hmmm. i'll find somewhere else to move them.

thanks for the help guys

 

Is this a joke?

 

^ if you were in front of my i'd punch you square in the mouth for being a dick

yes, it's a goddamn legitimate question

 

yes you needs those, your turbo and the wastegate work of pressure, that empty box of air distribute the same reading to all lines attached to it so it works together. BTW dont be to easy ticked, alot of people here are that way and you wont get any help by acting like they do either.

 

i understand your point and i'll try to keep my composure

ok, but i don't understand why they can't be removed still.....if you look at the flow of pressure and the direction the check valves work, it SEEMS like they can be eliminated without a negative effect to the turbo system

the vaccum chamber has 2 lines going to it; 1 in from the y-pipe (with a check valve) going to the turbo control solenoid...why not just go straight to the solenoid?

the pressure chamber has 1 line going to it; 1 from the rats nest that could be just capped off and eliminated all together.

 

honestly i never messed wit it, i have a single turbo now so i can't help you there. do a search on "rats nest" or vac lines and see what you come up with, IMO leave it alone, or just replace it with silicone lines if you want. If i were you i rather remove things that add weight or just clean it up, i figured out through many headach that this car is very tempermental so becareful. Also you probably herd this before but pretty much everything you want to do or thought of doing has been done and is on here so do a search first.

 

i like tinkering with my car.....i'm actually curious now cuz Mahjik hasn't said anything

 

The reason they exist is the fact that the system is not always under 100% boost. Therefore, the pressure tank stores pressure for when the source is not producing any and the solenoids need the pressure for their operation. The check valve is there to keep the pressure from leaving while pressure is not being provided to the tank. Same concept with the vacuum chamber.

If you want a working sequential setup, you need them. However, there are aftermarket vacuum chambers that you can use if you understand the system.

 

thanks mahjik, that explains everything

 

also, in order to keep the stock sequential system running correctly, what solenoids do i have to keep?

 

anybody know what solenoids i need to keep to retain the stock sequential system?

 

IIRC....
Turbo Pre-control
Charge Relief
Pressure reg. control
^Under the UIM in solenoid rack

WG control
Turbo pre-control

A side-note suggestion...
When you title a new thread, using relevant terms helps make it easier for others who have similar questions to search.

 

theres a guy selling aftermarket solenoids, ill try and find a link for you.

^Handling the stock ones are a joke. It seems like the crumble in your hands.

 

i've read saxyman's solenoid replacements, does anyone know if he is still in the business of making them? i haven't heard about him a while....

 

does anybody know if the stock solenoids are normally closed?

 

Inspection is on page F-177 of the FSM.

 

thanks

 

this is what i got from the FSM:

Purge Control: Normally Closed (duty cycle dependent)
Pressure Regulator Control: Normally Open
Turbo Control: Normally Closed
Charge Control: Normally Open
Double Throttle: Normally Closed
Charge Relief: Normally Closed
Wastegate Control: Normally Closed
Turbo Precontrol: Normally Closed

this look right?

 

Here's an overview of the turbo system:

great link, thanks mahjik

 

If you're into eliminating things, you might want to consider the double-throttle while you have the UIM off and the solenoid rack exposed.

i've already read about eliminating the DT....but i don't want the car to chunk on deceleration so i don't really want to get rid of the dashpot

 

Doesn't your Sig state

aren't you GREEN with envy"

You really need to reevaluate your goals.

With that said you really need to get a grasp on how the system operates. Your ignorance is obvious from your statements.

You have the impression Mazda just added stuff to make it harder for us to work on your car?

Remove the ABS to make room for other stuff? Relocate the solenoids because you think the location is bad?

It's only a matter of time until you screw up your car so bad you'll be selling it cheap. Lucky us......................
