Interesting to see the use of better OEM parts and ability to delete the vac canisters. I dig it. Like you said not best bang for buck, but will make for a clean OEM setup. Props for the project!
BQ Tuning N54 Intake Conversion

Dont know what the pricing will be on the custom inlets. Pricing on the OEM parts needed will be listed after the project is done for people to source on their own if they want them new or used based on pricing.
I haven't looked into RHD of what will differ .
umm...the lovely shaft that connects steering wheel to rack is what differs
its in the way...i have to lower the subframe to access rear turbo wastegates...

Yes I am aware of that, but wasnt sure on clearance for custom inlets.
They most certainly never released one in the uk. And even if they did make one for Aus or Japan etc.. then the 7s engine bay would be larger than a 3 or 1 series to accommodate this kind of intake

Real oem.com says that they did make one for the U.K.
That's funny as I checked real oem before posting! But thanks for Clarifying. Now after studying the real oem pics it's even clearer it won't fit a 1 or 3 series. Look at hot side charge pipe on the 7. Loads more room between engine and side of engine bay for It to Be routed/shaped that way. Also with the 7 being wider the steering shaft will sit further away from the engine compared to a 3 series. Hence why this intake can be accommodated on a 7
I guess we will just have to wait and see how it turns out. He did mention making custom outlets up to the union under the engine cover. So, it very well may be able to fit. At the very least it leaves any diy people only two small sections to make themselves.
Will the normal boost solenoids work, or are the 7 series solenoids required? Perhaps you're still finding out

If I am understanding correctly they are the same http://www.realoem.com/bmw/enUS/par...740i&mg=11&sg=15&diagId=11_3967&q=11367585425 .
If your talking about the vacuum converters mentioned above, I didnt even bother as the setup showed larger diameter vacuum hoses going in/out of the vacuum box thats integrated into the engine cover. The bigger vacuum hoses just slipped off the old vacuum converters, and I wasn't going the zip tie route on this. This had me thinking about the VTT thing that they stress a lot about in regards to vacuum lines on this platform. I just decided not to question it and stuck with what the BMW engineers had changed. I did have some wastegate rattle when cold and when shifting on the low side, now all that is gone.
Haven't read through everything but this looks pretty cool actually. To those I saw comparing this to a vacuum canister delete it looks more like a conversion. Much better inlet routing here than OEM for sure.
Yesterday I did some prep work on a 335is for a roll racing event. Checked for clearance, and there will have to be a different intake route for the 3 series and more likely the 1 series apposed to what I am doing on the Z4 in making custom inlets for the conversion setup
TFT and MMP make aluminium inlets, right ? These fit of course with some relocation of the coolant reservoir tank. So where they come up, and the DCI lodged, the inlets piping can be routed and extended to the OEM Y inlet going over the engine. When the vacuum canisters are removed the reservoir only needs to be moved up where the vacuum canisters use to sit and not to the other side of the engine bay. This will opening up the room in that area needed for the extension.

Have you thought about how you're going to route the incoming air into the airbox?
Only the Z4 atm. The current pre-intake box connection piece rfom teh 740i will be used as a mockup to 3D print an adapter to connect to the suction snorkel for the Z4. This same adapter can be used with the 1 or 3 series who want to route air from their original snorkel location also.
