Hi Guys,

I am soon to embark on removal of my OEM plenum and all the random stuff under the manifold but wanted to confirm that a hypertune plenum can actually fit in a bnr34 without having to remove the clutch booster and running a s-chassis clutch master cylinder?

its an ITB plenum like the one attached. now I'm not interested in the fact an OEM plenum is capable of power. this is an engineering project I'm embarking on with ITB drive by wire and will be comparing any manifold benefits around the 700g/s (900ish hp) mark vs the OEM manifold. there may be none, but I want the data. i have 6 EGT sensors for validation purposes.

thanks.

Should be fine if its just an RB26.  Only taller blocks have issues.  I have a greddy ITB intake on my RB34 high deck, and have had to shave the back off the master cylinder to get it to clear.  I still use the booster and an OEM clutch master.   The OEM plenum fit with plenty of room by comparison for an engine with the same deck height.  Your plenum will be 20mm lower than my setup.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
