Boost Solenoid Gtr R32

[anfo2gig]

Hi,

Just wondering on the GTR R32 boost solenoid there are two pipes connected to it, I want to know which pipe goes to the waste gate?

1. The one that has the restrictor, pointing to the engine

2. The one without the restrictor, pointing to the battery

Thanks,

Guys

Anyone?

cant remember, im sure if u take both the lines out of the controller then disconnect one of the lines off the actuator and blow in it youll be able to figure it out

thanks Joe

hrmzz but im not too technical with the car, so I can only locate the boost solenoid.... so if someone could point me to the correct direction would be great

With the engine running, one of the hoses will be sucking air in like a vacuum cleaner, just put your thumb over it. That one will be the one going to the intake manifold/engine.

Thanks Lance,

I just want to know is this Diagram correct?

Green line from the solenoid = The one without the restrictor, point to the battery = line goes to the wastegate (Green line)?

Thats not actually correct,

the actutator lines should only be plumbed into the boost solenoid ( as apose to also being plumbed into the "bottom of collector, Boost source" like in the above picture)

Thanks Joey.

FYI SAU Members

The one without the restrictor, point towards the battery is the boost line

The one with the restrictor, point towards the engine is the waste gate line.

If the diagram is not correct, cna someone please amend it / edit post so it *is* correct?

I have a similar plumbing problem... my GTR has been mucked with.

Diagram is good for those of us with a pile of parts on the table

+1 for that I've been avoiding my boost lines for a while now although I'm glad to see that the evap purge lines that run behind the rear timing cover are only emissions stuff cause I forgot to put them back on before setting all my timing up and I'm not taking the timing belt off again just for that.

Not on a STD GTR.

That diagram look right to me. If you remove the pill it can bleed more boost source from the actuator line - hence increasing boost.

[GTR_JOEY]

just had a look at the manual and it would appear the diagram is correct

[GTR_JOEY]

The blue line bleeds off to the inlet of the turbo to allow more boost when the plug on the solenoid is pulled enabling the higher boost level

i stand corrected... lessons learned

well according to that diagram theres a direct line between the manifold and the actuators, somethings is not right there

pretty sure the green and blue are ass about in the top half of that diagram

Your wrong. Thats how they came out. The solenoid is only a 2 port. Meaning that if it is not energized the signal that the actuators get is the full signal from the +ve side of the throttle bodies(hence minimum boost or actuator pressure).

When the solenoid is fully energized 100% duty then you are bleeding the maximum amount of boost the solenoid can flow away from the actuator hence reducing the signal to the actuators and increasing the boost. If you want more boost then removing the pill will allow more flow and reduce the signal to the actuators even more.

If you hook it up the way you have suggested then at 0%duty you will have no signal on the actuators hence shitloads of boost. Follow the diagrams guys and you will be sweet.
