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.

      Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?

      My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.

      There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.

      I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.

      Yeah - I mean, go the other way. Smaller range. Not larger.
