Can These Be Low Mounted On Stock Rb25 Neo Manifold?

Ok after reading countless threads and online material, I thought I would post it up due to getting many conflicting pieces of information:

I am deciding between a Kando T67-25G/ TD06-20g or Precision 5558/ 5557 for my R34 RB25 -low-mount ext gate setup, stock exhaust manifold and cooler pipes over engine from drivers side/past fan and over the cam covers.

The Kando thread has numerous posts indicating the T67-25G can NOT be low-mounted, even with a thick ass spacer. But then a dude on here has told me it CAN be. Someone else suggested to try a smaller 3" comp cover for the T67 (would make less power I know).

Second option is a Precision CEA 5557 or 5558, can THIS be low-mounted as above? I would want to know if its physically smaller or bigger than the Kando T67?

Has anyone actually succeeded in low mounting these on their RB25? Please let me know. The T67 is my gun choice. Top-mount manifold and re-routing/shortening the cooler pipes is for the next stage as it adds more cost - relocating the BOV, sensors and hoses that come with the layout. These are on the way of a high-mount turbo - see pic of what my setup is like.

If these two options above are not possible then I have to settle with the smaller Kando TD06-20G 10cm. Please don't ask me to get a HG or a GT3076R, as these two are not on my list. I'm after brutal delivery / around 280-300ish rwkw as opposed to smooth and linear.

I have two turbos to eliminate from my list of three and need your help ;)

Did you get a dyno printout ? Any reason why you chose the 5558 over the 5858 ?

old version/new version i think, back when i first saw ron's results i hadnt come across the 5858 in my research, it only popped up a couple of months ago

No, a 5858 was available at the time. Ron has asked me about which to get, I believe he settled on the 5558 as it was tried and tested by another member.

IIRC his gate it off the turbine housing. It is definitely a JB, I sent him the link to buy the oil line lol

For the love of god stay away from the smaller or all the precision turbo's.... I've been there and they fell on they're face.

Best thing I ever did was go to a trust t67 10cm.

I'm not sure you can go low mount a t67 but nothing is impossible. Personally I would take a good hard look at a t3 rear, 8cm td06 with a custom core from hypergear.

... my 5557 and 5558 with two different wastegate set ups were useless compared to a plain old td turbo.

      Magnetic Drain Plug Snapped in Half

      By kevboost7 · Posted

      Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.

      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.... 😃

      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.
