Got Boost?

Hey guys,

Pulled my standard turbo's off my R34 GTR and i'm amazed at how many more hoses, lines and pipes there are on the factory setup. It got me thinking, when i've looked at a lot of 26's that have been modded with low mount twins etc, a lot of the clutter and work that is there from factory is gone, it seems all the lines and piping is much tidier and there would appear to be a lot less of it! Is this the case? i'm wanting to follow similar procedure if thats the case, before i put my other turbo's on id like to purchase whatever aftermarket parts are needed to tidy it all up and simplify the setup. If im completely off track let me know! Otherwise any information on what gets done would be awesome! Thanks.

Edit - I am planning the purchase of a HKS Hard Pipe kit, thats about the only one i've planned thus far though.

Are you sure dude?

Which setups are you talking about?

There is a need for just about everything if your going the stock position low mounts.

Maybe it "looks" tidier because of people painting/polishing of the piping perhaps?

Careful altering the piping though, sometimes it can cause mild shuffling due to the new pipe meet points etc

Well its more then possible that when it gets redone, the lines and piping are just organised a lot better, tidier and hidden etc. I didn't get to examine the setups, just look across from the top and admire how neat it was.

on the intake side there is the PCV valve, AAC valve, air chamber, bov lines, boost lines about 20 hoses. but unless you are getting rid of the valves (which help idle, cold start, aircon etc) there's not much you can do.

on the turbo side also not much you can do. you need boost line to the wastegates, and the turbos are air and water cooled.

I reckon there is a madman working in nissan's design department somewhere though. "muahahha lets add a loop to this line! what if we ran bost lines right around the engine? lets loop it all with coolant too muahahhaha"

second on the mad engine design crew!

Just got rid of just about all of them the 2 main vacum pipe outlet now go to the brake and clutch boosters 1 water line round rear of engine to turbos and another between the thermostat housing and rear of block. 1 small vacum line for boost control an one to bov rest plugged up

lol definately was a madman working in the design department

Agreed; its like a birds nest of lines on the turbo side of the 26. This is what made the decision to go a single highmount turbo much easier for me.

Unfortunately, all the lines are neccessary if you want to maintain twin low mounts in the standard position, and its a street driven car.

I painted the hard water lines in a black exhaust paint, which made them disappear a bit, but it also makes them hard to maintain. My engine was also on a stand, so it was much easier to do.

Shaun.

      New fix for low tyre pressure from bmw

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.

      You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
