boost contoller plumbing

[switch]

Is my blue pipe shown in the pic (out pipe) supposed to go to the top of the solenoid or somewhere on the turbo?
Sorry to be so thick. I got this far, and I want to finish the job!

Think the other end of the blue 1 goes down to the actuator on the turbo mate.

cheers Eddie, i'll take another look at it.

Ok, dodged the rain this weekend, but still wasnt sure where the blue (out )pipe goes?
Can someone tell me what the 3 pipes are in my pic? Pipe (1) has a 'T' in it which forms pipe (3), and i have no idea about pipe 2? My manual is at a mates house in Wiltshire Im guessing i can either join onto one of these, or replace?
Help!

hi mate

someone PLEASE correct me as I am working from memory and don't claim to be an expert.

Point 1 should be connected to the "out" pipe of your electronic controller.

The top solenoid pipe should join to a nipple on your inlet tract.

The rest looks ok.

Here's a pic of mine, u can't see too much but may be enough (I have a manual boost control).

It should also be possible to bypass the solenoid altogether, but I'll let others comment on that as I didn't do it on mine.

From my faded memory of fitting a Profec to mine, one pipe goes onto the compressor's pressure outlet (on the turbo), the other goes onto where that hose used to go, ie the wastegate actuator, and the 3rd hose goes to a nipple on the inlet manifold which allows the controller to read the boost pressure and manipulate the wastegate accordingly. I won't try and instruct you on yours in particular since mine is different, but that should be how it works.

so correct me if I am wrong, but I assume to bypass the solenoid you would connect the intercooler hard pipe exiting from nr the plenum with the hard pipe exiting the turbo compressor, T'd to the boost controller which exits to the boost control port on the wastegate.

I was wondering if I should bypass the solenoid alltogether? I know the silver (in) pipe is correct, but currently, I have the out pipe conected to the top of the solenoid and the spur pipe (3 in my pic) is connected to the bottom. I know this is wrong as I havent got control over the boost.

Has anyone got a good pic of their solenoid that shows the pipework OK? Oh and thanks for your efforts so far, much appreciated.

hi mate, if you are keeping the solenoid then your outpipe from your controller should go to the T-piece that you have currently got blocked. This joins to both the wastegate and the bottom port of the solenoid. The top port of the solenoid should connect to the compressor housing.

if you want to ditch the solenoid then I BELIEVE (ie, I'd rather you check with someone else as well!) you should connect the outpipe from the solenoid to the T-piece, which then goes directly to the compressor housing and the wastegate. I stress I have not done this - I just believe it will work - end of the day you don't need 2 boost controllers (which is what the solenoid is).

There are possibly different configurations that will work... just giving you how I have done it / would do it.

Cheers B&Q, im wondering if i would be better off without the solenoid then?

Like you said, why have both? Maybe someone will have an opinion? Anyway, have drawn your proposed solution to doing away with the solenoid altogether. Maybe someone could confirm it for me please?

i don't see where the pipes below the blue goes. I would of thought you'd need all the outlets on the T piece. I still see it blocked?

[switch]

in my mock up, I was thinking that I have got to join the blue pipe to the T'd pipe that was originally on the solenoid? Then leave the other two pipes blanked off as already shown???

[B&Q]

I don't think you can cap that pipe mate, surely that is the compressor outlet? I can't really see the picture that well but if it is then this needs to be reconnected to the T. There needs to be a vacuum connection between it and the compressor reference port (nr your plenum), off which is the boost controller connected to the wastegate.

to play safe I would reattach all the pipes and plumb the controller in-line to the T.

tbh mate, I would get someone to check it for you if you are unsure.... if the turbo boost isn't being controlled it will just keep boosting and blow your engine. That's bad!

The solenoid that comes with the boost controller replaces the shitty nissan one.

Very!
so all I got to do is connect said blue pipe straight through to the turbo? incidently, which pipe will be obsolete? the thicker one with the T junction in it, or the smaller pipe?
No doubt I will find out when I trace back to the turbo!

cheers all
