Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

[R34_GT to Turbo]

Looking to do a turbo conversion on my RB25DE Neo

Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold? 
 

I found an upper only intake manifold for sale but not sure if it will fit the bottom  half stock intake manifold I have already? Thanks 

Also if your selling any parts relating to RB25DET Neo pls reply below or dm.

I'm not sure if it will bolt up, but....

I'm reasonably sure that the ID of the runners is somewhat smaller on the NAs. So it probably wouldn't be a good match at the flange where the top and bottom meet. So that would be a reason to not do it.

And the skinny runners would be the bit you're keeping, which would be a reason to no do it. You'd want the big runners if you were doing any work to swap stuff.

Why not just use what you've got, like nearly everyone else who has +T'd an NA? You don't need or want the TCS throttle or other stuff that is specifically DET inlet/crossover.

Ok I get you. But isn’t the butterfly intake a headache with the +T? 
see this is my plan so far but please advise me into the right direction. 

Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor. 
 

I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks

I've never understood why this bothers people.

Surely you'd be looking at a T3 flanged Garrett style thing, rather than a TD?

You're unlikely to push a +T hard enough to need that much fuel.

Nistune Ecu,

If you're not starting with most of the things you need to do that (ie, the bloody ECU!), you're better off just going Haltech/Link. You wil hate life a lot less.

No. Just no.

Just turbo it as is.
