Stock Boost Controller 4g93t

[vonga]

hey guys just wondering what does the boost controller looks like? and how it all plugs in? lols

cheers

 

[gsr-mat]

isnt the boost on a stock 93t regulated through the wastegate? i dont think there is actually a boost controller like you would find turbosmart etc selling

 

[evo-gsr]

There's a boost solenoid.. Is that what you mean? Under the battery tray...?

sorry to raise the dead, but can someone give us a pic. i have the solonoid and the funny bracket and found the wires to plug it too. but what bolt holes does it bolt to?
post a pic, maybe the jumbuck doesnt even have the right holes

 

[EVOCPE]

hose off the actuator to a T piece, 1 side goes to stock boost controller, the other side to intercooler pipe, the other nipple on boost controller to the intake pipe between turbo and afm

 

[4piknup]

thanks for the connections, but where does it bolt to, i know its under the battery tray, but what holes?

 

[EVOCPE]

ummm it bolts to the standard intercooler bracket (blue circle below)



Or you can put it where Neil put his

 

[khubner1]

is the solenoid your refering to in that picture if so mine goes between the intake manifold and the fpr and bolts to the resistor pack bracket

 

[EVOCPE]

Nope, that's a different solenoid, has nipple on side and bottom, the boost solenoid has 2 on the 1 side

 

[khubner1]

hmm i probably don't have that plugged in then. is it bad not to have it? what exactly does it do?

 

[Smutt]

+1... what is this boost solenoid supposed to do....?

mine is electrically connected but not pneumatically connected (just looped back on itself)...

 

[4piknup]

allows the ecu to control the boost at any level higher than the wastegate actuater pressure. at the level, it will allow boost to pass through the solonoid to the wastegate actuater. it is also required if you have a EBC. it allows greater control of boost and should get to full boost earlier in rev range as the wastegate isnt creeping open as it gets close to its rated pressure. everything that is good with a EBC will apply (if the ecu has the boost set where you want it)

what does the one khubner has pics of do? does it drop feul pressure when engine is shut down for some reason? or maybe it supplies boost pressure to the fpr to make it a rising rate fpr?

 

[Smutt]

Interesting.. but does not makes sense for what and how I have it setup.. (no biggee)

as above... mine is not connected pneumatically... therefore sensing no pressure...

I have been using Eboost 1 for years now and Factory ECU chipped / hacked and tuned... Very similar to ECM-link I believe... and running above 20psi....

The EBC should handle how fast it gets to boost, boost creep and any spike issues (all change-able in the settings of the EBC)..

As for the pic from khubner1... the solenoid shown on the very right of the picture is the one mounted to the firewall... again... mine is electrically connected but the vacuum tube loops from the bottom up to the side port.. sensing nothing...

 

[khubner1]

smutt that one you posted is the same as the one i posted a pic of. goes between the manifold and the fpr.

and i think it's the fuel cut.

evo cpe what kind of plug does the one in you pic have?

 

[EVOCPE]

Generic 2 pin plug (1 vertical, 1 horizontal)

The sensor on the firewall is all got to do with emissions

 

[khubner1]

ah HA! that what that one was for. lol i'm using it to power my boost guage. constant 12v power supply only on while running made sense. maybe i should change that.
