    Just put it back as it should be, people do things for strange reasons. More than likely at some stage someone has had a aftermarket boost controller attached and they required a direct feed of manifold pressure. Get a mirror to help you see with a torch to shine onto it.

    Couldn't get the hands in close enough to get at the ends under the plenum, so have used a straight connector and some snail clamps.

    Changed oil and filter, just need to fit new battery and all ready for rego.

    Oh and the obligatory after change degrease (oil filter relocator kit isn't bulletproof for not spilling oil :P )

    After three degrease routines and poking around with a massive overhead light and a tube I traced all the lines.

    News is still breathtakingly odd.

    The line that goes from the back of the plenum, and is supposed to connect to the T metal tube line (under plenum) actually goes to a Y fork that has been installed in the std boost controller line at the front.

    The line that is in the T metal tube (above) goes nowhere and has a bolt in the end.

    The std boost controller lines are plumbed up OK (with the exception of the metal Y fork). So I think I will be getting some odd boost spikes - not a lot of pressure will make it down that tube.

    Since I can barely see these tubes, let alone get my fat anglo paws inside the spaces, should I cheap-shot and just buy some tube connectors, or re-tube them all with the proper lines. I'd like to do the latter, but if i'ts going to be a sh!t of a job, I'd rather not start....

    the rear/smaller pipe is the wastegate pressure source. it does connect to the "water tube" assemly but there are 2 air lines attached to it to. 1 end goes to stock boost control solenoid and the other to the wastegates via the back of the motor. it is a good source for a boost controller.

    So far:

    - two big ones are OK

    - small one goes directly to the factory boost controller via a dodgy plastic connector (not via metal tube).

    f* ony knows what the wastegates are connected to. I know they are connected to the metal tubing (I did this myself when I rebuilt turbos). There's pressure there so it must be wired up to something else.

    It's almost impossible to see the tube under there. Half the wiring is obviously in the wrong spot as well.

    If inly I was 4 foot tall and had tiny little hands instead of being 6'2" and 100+ kgs :cheers:

    Ok, well the one marked AAC valve is as it says, for the Idle control valve. The one that says goes behind the AAC valve is for the Air Regulator which is for cold starts, the 3rd i can't confirm where it goes till i get home tomorrow. If it says water tube then its refering to the pipes that run behind the back of the head. Let me get back to you and i'll make sure we sort it all out properly. If any arent connected you will have a big leak under boost, not so much vacuum leak. Slightly under part throttle, off boost.

    Deren

    I had a poke around today and the tube that comes up with a bolt in it is connected soemwhere below the plenum. one of the tubes connecting to the stock boost controller is to the middle one. i've pushed the car into the sun and will have a look from underneath.

    If you have a pic or can take one of your piping with the plenum out it would be a great ref :)

    Cheers,

    My plenum is out getting chrome plated currently at the moment. When i get it back i can take a pic for you if you still need it.

    Yes please, just to check.

    I have found a pic of a stock plenum, and found a manual on line. I've marked up the "where this one goes according to manual".

    My setup obviously isn't right

    The fact that I have a large hose from plenum not connected to anything is a worry - will be chasing it down tomorrow (just wish I had a camera on a probe - it's f* terrible tracing anything under there).

    Cheers,

    I have a vac hose that comes out of the back of the plenum and goes no-where. Does anyone have a plenum out, and could they mark up where each line goes? Please? (on a stock R32 GTR?

    thanks!

    Need A Little Help..... With My R32 Gtr

    1/- Anyone have a stock-ish engine bay with a GREX oil filter relocation kit? Mine needs re-doing and I'd like to see a decent engine bay (pics or in person).

    2/- I have a Power FC and integrated boost controller - I would like it fitted and dyno-tuned and mapped (properly and without hassles). Recommendations for post here, against please PM.

    3/- HKS Air Pods - the 3 layer filters are on back order in Japan, so if you need spare elements soon I'd be ordering now..

    Cheers,

    yeah i see it in the first pic. that is wierd unless you are running a boost controller too. the only small vacuum line under the plenum is the vacuum source that runs to the air lines for the boost control solenoid (which you still have), and then back around behind the motor to the stock actuators. if that was plugged your car would not have proper (any) boost control unless something else has been changed under there. Dont worry about it if it is running fine

    It's one (*of two) larger ones. Thge stock actuators are definitely connected (had to rebuild turbos).

    There was a boost controller fitted (with hole in hose).

    I asked mech to take it back to stock - he came up with the bolt in the hose cause it wouldn't fit to anything.....

    I think I need to check all my plumbing again..

    yeah that one is stock! except you have the wrong battery (terminals the wrong way around, and larger posts than standard so the cables don't fit properly). You really should not drive it around like that it is in danger of coming loose/shorting/burning the car to the ground.

    what holds the other side of the oil filter relocator in place? one side has a bracket going to the strut tower, but what supports the other?

    Battery is a temp fit - spare from the boat (original died, again).

    nothing holds the filter in place apart from the bent flat bracket.

    Note filter is ssmack bang in front of dipstick....

    I really need to see a stock engine bay - i've got a spare vacuum hose coming from engine (with bolt in it)

    Heres mine... I use a genuine nissan filter on it

    Yours seems to be the same - the restrictor unit and other stuff has been removed/relocated.

    I think they've shortened the oil cables/sheaths as well (!)

    Here's what my (rather pathetically stock) engine bay looks like:

    Does ne1 have a stock engine bay?

    There also seems to be something missing - there's a bracket on the tower with nothing on it.....???

    hmm lots of changes in that engine bay. boost controller and coil thingy normally lives there. and hicas solenoids. no room unless you've removed them all

    I was hoping that was the case - my engine bay is a lot busier - also I don't remember there being right angle connectors (I think mine are straight in) so may not be a Grex kit?

    I don't have the oil cooler or other go-hard parts (running std boost) so a stock pic would be perfect....

    Cleaning Pistons

    Soak in Kero for as long as you can. Will soften, but it takes a long time.

    Don't use a wire brush as it will scratch surface. Use a fine bronze brush, or a die grinder with a polishing cloth fitted.

    if they are pitted, new is the go.

    If they are carboned up, look at leaking turbos, valve stems, or broken rings.

    Also if engine has overheated, piston rings lose their tension.

    The guys that fitted my oil filter relocation kit put it in front of the dipstick on a homemade bracket (flat bar) becuase they reckon they couldn't close the bonnet on the filter.

    If someone has one fitted properly to a BNR32 could yous please upload a photo of the filter location on the strut tower plus another where the pipes are run (mine are rubbing on the plenum and that can't be good.

    Any advice on a suitable filter to use (the guys chucked the installation manual which had the sizes etc on it )

    Thanks! :P:worship::(:worship::)
