No, you can ignore what StevenCJR31 said, because it's not true.

bullshit. . ive got both motors side by side here and the intakes from the r32 rb25de and r32 rb20det DO NOT swap over they ARE different, dont go quoting shit

That's not what we're talking about. He is talking about putting an RB25DET head and inlet manifold onto an RB24S block. The block of the RB24S is the same as the RB25 block (except perhaps it has no oil squirters and possibly no hole for the knock sensor(s) ).

So your post was completely irrelevant, and it sounded like you were talking about RB24 that was based on stroked and bored RB20 stuff - which was NOT the topic of discussion. So I kindly invite you to back off.

absolutely nothing . . it was in answer to what roy said on this thread on 01/03 at 14:23 about the intake manifolds being VISUALLY the same on the na 25 and 20dets, i was mearly pointing out that whilst visually the same they are in fact different port size and stud pattern and therefore not interchangable, same top feed fuel injectors and fuel rail tho

I tell you what, we really need to fix the new forum software so quoting works properly again. I had to go over those posts 4 times to follow exactly who was saying what again.

I apologise for coming over like a dick. I should have said "not relevant" instead of "not true".

NA RB25 has no oil squirters either iirc, just the provisions for it. But having no hole for the knock sensor, would that be a problem?

I'll be getting the engine this week, thanks for the help guys.

Hole for the knock sensor could be gently drilled and tapped (give the example to follow on the other block). Worst case you do not install the knock sensor to the block. You just connect it to the wiring loom, wrap it in foam.bubble wrap and gaffer tape it to something solid. Or an even worse case, you don't connect it to the loom and you just put a resistor (there's a certain value you'd need, search it up) across the loom plug and the ECU won't know any different. Either of these leave you exposed to a little knock damage if your tune is a bit ragged or you get a gut full of bad fuel.....but that's no different to most people who are using aftermarket ECUs anyway, seeing as they don't usually use the knock sensor either.

      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?

      By sunsetR33 路 Posted

      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.
