im starting to do an rb25/30 motor, and i have somes questons on the heads, coz i have an series 2 whole motor and just a series 1 head for the rb30 im doing, but i wanna use the loom and VCT off the series 2. (so wanna keep the series 2 motor a pretty much complete motor and head)

QUESTONS

1....... i wanna use the loom off the series 2 on the other motor/head, will it work on the series 1 head???

2........and i have to use the series 2 varible cam timing stuff will that work???

3.......... With new cams i've heard not sure tho the series 1 and 2 have different cams if so would i use series 1 cams cause its a series 1 head OR series 2 cause im using the loom and varible cam timing stuff for it???

4.... SO REALY IS THERE MUCH DIFFERENCE IN THE HEADS, VCT AND LOOMS???? ((( i already know about the ignitor modul in the series 1 loom and not in the series 2 )))

i dont know of any, the ecus are interchanageable other than slight map data change

the powerfc is direct plug in unit for both car models with no physical wire or code changes

a known difference i can think is s1 afm is 4 wires and s2 afm is 3 wires

the changes for this are done in the engine looom wiring and not the wiring loom at the socket side

that is, the s1 ecu doesnt handle the afm ground differently to the s2 ecu

another one i can think of is next to the TPS the s1 has two plugs, one is disconnected always

on the s2 i think both are connected. again i think those changes are done on the lcoal loom and dont have anything to do with the ecu side

    • 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!
    • 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.
