Sorry for the newb question

but could some one give me a simple diagram (like xxxx > xxxx . xxxx etc)

on what happens when you boost

like where it goes from the turbo with specific reference to fmic and bov (which where my boost guage is connected)

got a boost leak

if i can understand this it will prob put in right place to look

thanks

So what ur saying is-

U want to know how to find a boost leak ?

U want to know how a turbo works ?

U want to know the routing of R33 intercooler pipes ?

Also u mentioned a BOV, if its an atmo one dont bother. It Will only cause u idle and fuel economy issues. Stick with the stock one.

hahaha but those pages dont seem to answer my question

and want it more answered towards a r33 style turbo set up

not some home made science project

please read the question before posting thanks (not just the post)

Oh, well in that case, let's start with this:

My link

After you've read that, then read Messiah's post, then refer back to my first link. After all, can't run before we can walk ;)

URM OK

THOUGHT THE REPLIES WOULD BE LOT MORE USEFUL

HANALDO WHICH ONE OF THOSE GOOGLE RESULTS ANSWER MY QUESTION?

AS I CANT REALLY FIND WT I ASKED IN OP

OK WHAT I WANT TO KNOW IS WHERE THE BOOST (AIR) FLOWS FROM THE TURBO?

ORIGINALLY HAD A BOOST LEAK BUT I KNOW IT WAS COMING TO THE BOV (AS THE BOOST GUAGE IS CONNECTED AROUND THERE AND I DID HAVE FULL BOOST READING)

I DID LOOK INSIDE AND SAW THE FMIC JOINING AT THE FRONT WAS DODGY (SILICON JOINERS ANID CLAMPS), REMOVED THEM AND REALISED I CANT PUT IT BACK ON WITHOUT REMOVING HALF OF THE INTERCOOLER PIPING (WHICH I WILL DO LATER)

NOW I HAVE NO BOOST BUT IM HOPING ITS JUST BECAUSE EVERYTHINGS LOST AROUND THE INTERCOOLER

SO THE REASON I ASKED IS SO I CAN KNOW WHERE THE POSSIBILITIES ARE IF ITS COMING BETWEEN THE BOV AND ENGINE

AND JUST TO MAKE SURE THE FMIC COMES BEFORE BOV, OR MAYBE I HAVE ANOTHER PROBLEM

IF YOU CANT HELP ME WITH THIS OR ANSWER MY ORIGINAL POST, DONT REPLY

I KNOW HOW TO USE GOOGLE

NO NEED FOR SMART ASS COMMENTS (YES I KNOW I POSTED EVERYTHING IN CAPITALS - HOPEFULLY YOU CAN READ IT CAREFULLY BEFORE REPLYING)

I think i know what ur getting at, u wanna know which is the outlet pipe off the turbo ? Look at ur engine from the front, u will see a big cross over pipe and a pipe connected to it, now look below that pipe and u will see another one that sorta runs parralel. Thats where the boost comes from, the lower one of the pipes, if u follow it back to the turbo u will see a 90degree elbow, thats ur outlet from the turbo.

Nope, now I can't read it at all. I read this part. And now my reply is probably pretty useless, because I doubt the rest of your post was in relation to your ill-use of caps lock.

Honestly mate, my first post was helping you. If you don't understand how these things work then you're not going to be able to find and fix problems. It seems pretty clear to me that you don't understand because you are asking a question of something so simple. So do us, and yourself, a favour by reading about how these things work. A Skyline isn't inherently different from any other turbocharged/intercooled engine.

At risk of feeding a very hungry troll...

turbo_diagram.jpg

it should be pretty simple to relate which pipes go to where.

start at your air filter, follow it back to the turbo, air goes in there. gets compressed then leaves the compressor housing (silver bit) then through to the intercooler, cools its shit down, then up and around past the BOV and to the throttle body -> engine.

p.s. i found that pic in 3 clicks and 11 key strokes...

    • No intention of driving the car the way it's set up now, just wanting to make sure I haven't made any mistakes along the way so that the tune can go smoothly, I don't want to waste anyone's time with stupid issues. And of course I intend to get it towed to the dyno in a completed state 😅 I have the base fuel pressure with the vacuum disconnected set at about 40psi, which I believe is at least relatively close to stock fuel pressure, maybe I'll have a fiddle with the reg and see what happens. For all I know I could be wasting my time with this and I should just plumb it in and see what the tuner reckons. I just find it a bit strange that it seems to be under so much load just free revving, but maybe that's just a result of the turbo slowing down the exhaust gasses and making a restriction in the flow, with no boost to compensate.
    • The boy just hit up google translate and it worked a treat, he said step one was "please urinate with precision and elegance", he then sent me the correct translation  I get some new loctite for the small fixtures tomorrow and get some "dort" going after that 🤣
    • Right, so is the fuel pressure the same as it was previously? If not, well, it's not going to work well. I can understand the theory I assume you are going for, which is: "Run it N/A, and if I have the original AFM, and same amount of fuel and intake air as previously, the fact there's a turbo in my exhaust should still make it run" Which it... might? Provided you don't actually change how much air or fuel is going into the car.. or getting out. But if you have changed that, all bets are off. What is the purpose to even have the car run this way? To get it to a tuner? And if the goal is to limp it to a tuner, you're still going to what - plumb up a whole intercooler system and new intake in the parking lot out front before your tune......?
    • Haha yea it's a bit of a weird setup at the moment, just wanted to make sure I sorted out any headaches before dyno day. At the moment I've changed the exhaust manifold, turbo and downpipe, 460lph fuel pump and rising rate reg as well as the previously mentioned headstuds and gasket. The nistune was already mapped for the car as it was and drove around for a few months no worries. The plan is to run flex fuel hence the big pump, which I've wired direct to the battery through a relay to avoid voltage issues.
    • Um. Was the ECU the same as the one previously there? I know R33's needed R32 GTST ECU's or other tomfoolery to run Nistune. This is such a wild setup. Most people would plumb in the turbo then not drive the car (i.e tow it to a tuner). What's actually changed since it last ran?
