Turbo and boost controller

Now i know how things work on single turbo and how to hook up a boost controller.

Twin turbo i even worked that out but whats confussing me is what so called proffesionals did to it to get the boost up.

Now this is how i think it should be hooked up
Both wastegate hoses connected via a T piece.
Both manifold hoses linked via T piece

Connect the two T pieces and u get stock boost.
To fit the boost controller solenoid is to put it inline with the hose connecting the wastegate hoses and manifold hose.

I hope that makes sense if not ill draw a diagram.

Now the pro did similar except he blocked the passenger manifold hose and is only using the driver one.

Shouldnt it for balance reasons and to ensure same boost pressures between two banks this be hooked up with the other side as well?

Or em i confussing myself?

I still think left wastegate should be linked to left manifold (turbo compressor) not to the opposite. If wasnt needed y did nissan put it?

Hope someone can shine some light on this for me.

 

The way you originally explained it is correct. As far as I know that is how everyone else installs boost controllers on our Zeds.

Both wastegates connected to the Boost Solenoid single wastegate using a T-piece.

Both Intake hose nipples connected again to the Boost Solenoid single feedback port using another T-piece.

Then from memory, you use the same hose for the stock in-cabin boost gauge and connect that (if you'd like, using another T-piece to retain stock in-cabin boost gauge functionality) to the third and only left Boost Solenoid port. Assuming your Boost Solenoid has the three standard ports.

Thats it. Assuming you've disconnected the stock safety boost solenoids and / or run a single dedicated line straight from wastegates to Boost solenoid.

I had a picture drawn up but its on the desktop computer at home, on my laptop at work right now.

Both ways are correct. I do it the same as your guy did, block off one nipple.

There is no reason to feed both boost signals into a tee piece, pressure in the system is equal on both sides no matter what each individual turbo is doing, the balance pipe makes sure of that. Pascal's law tells us this is true (although technically relating to fluids under pressure, most gasses, including air, perform the same way when compressed)

 

Can someone illutrate the connections through a simple diagram? That will definitely shed some light especially to the noobs like moi...

 

Ive done that hundreds of times. Search mate.

 

Thanks to drz400y. Was able to dig his informative answers to boost controller connections. Always been helpful. Cheers to you, mate...

 

Here is a diagram borrowed from turbosmart



Only difference i was talking about is to hook up the other compressor connection as well. Same what nissan did originaly. But as explained above not necessary.

 

Diagrams always make a discussion more tangible. Very helpful piece of info. Thanking you...

 

RBZ 260, if all goes well and im in Adelaide next for a price and some cold bevys you could even help me with mine ;-)
