RB26 plenum size

Hey all,

I will be putting an RB26 plenum onto my RB20 and i am also wanting to use Wiggins couplings on my cooler piping. Was wondering if anyone knows the inlet size of the RB26 plenum?

Not the throttle body size but the actual opening on the mouth of the plenum itself. Piggaz i know you were using wiggins clamps so maybe you could remember? I assume it will be a 3" clamp used. Thanks

Just looking back at your build thread and in the pics you used a 3" silicone on your plenum not a wiggins clamp. Did you end up going wiggins straight off the plenum?

I'm keeping the 3 inch silicone joiner there. I wasn't prepared to pull the plenum off to weld it. If it does come off or the engine comes out, I'll throw one on. The Nismo plenums are a little more tricky to do than the factory units.

    • Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers
    • Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
