I believe that is the OEM vacuum reservoir... Could be wrong, though. I believe your exhaust injection system runs off that (the system that recycles exhaust gases to help warm the cat up when cold), but again, I could be wrong.

Quite a project you got here.

 

That makes sense it looks like a vacuum reservoir. Wonder if it is any use now that I convert to turbo, maybe i can remove it? I have to investigate.

 

Continued abit with fuel return system today aswell as grinding and painting chargepipes. Unfortunately I have alot of other stuff that takes my attention these days. Short session in the garage.

 

its lookin really good bro... cant wait to see how it all turns out....

 

Is the vacuum reservoir good for anything once being turbo converted? I didnt remember to check yday, but it seemed like the only hoses were going to that crappy device that originally sits on the stock intake.

 

Did some more on the build today, was intending to get more done, but after I had soldered the relay stuff in the trunk I got a headache and felt like throwing up. Maybe I was affected by the fumes in the narrow space of the trunk. I tried to not breathe them, but maybe I got enough anyway. Was a mix of fuel and solder fumes. However here is what I managed to get done.

Made a holder for the boost gauge in the center console. Ash tray to the bin and the holder in its place. (Just test fitting the gauge by using the oiltemp gauge if anyone wonders)


Closed position


Replaced the fuelpump with the walbro 255 gss342. On my previous car this was plug and play since there was a hose between the pump and the fueltank insert. On this car the hose was replaced with a plastic pipe of a static length apperently with rubber sealings. This means it wasn't plug and play anymore.

Here are the pumps beside each other. Notice the height difference. In this pic you can see the fixed length pump pipe aswell to the right of the pumps.


To make the walbro fit, I did this.


Tank insert is ready!


Here I am soldering the relay stuff for the pump. The stock fuel pump circuit is opening the relay. The relay has a 30A fuse and a direct connection from the battery to the fuelpump. Using 11gauge cable. (4mm2)


Its starting to become time to put things in place and put the car together. So here I am making sure the compressor housing of the turbo is correctly angled. The first piece of chargepiping is also in place for this pic. (Black painted)


This is how roomy it will be between the fusebox and manifold. Decent.


Also welded an aluminium connector into the vat today and put the vat back on the engine. So now it feels the worst part is done.

Thats all for now, I hope to feel better tomorrow so I can continue.
Next up is mounting the manifold + turbo with all hoses attached. Hopefully not removing it for a while.

 

u can remove the vacume resevoir, the build is really coming together nicely man, are u still gonna use that heat shield for the manifold?

 

Yes the heatshield will be used, however its not the prettiest creation in the world so I'm looking at it more like a short term solution and extra safety for now.
Thanks for the reservoir comment.

 

I think it can be removed too... I think it was part of the exhaust injection system (the pump that was up under the driver's side headlight that can be removed, and the "mushroom cap" valve that is on the rear of the intake manifold (at least on my MY00... not sure about MY06+).
