If doing a DBW with ecu/loom can now do it on factory plenum

Yes, I currently have a modified factory plenum with single throttle DBW

Then just keep the factory plenum  

No need to burn more money on a fancy Plazmaman plenum for little gain (if any). It does look good though, billet dis dat albeit for a Rb25 shit box.

Yep, my mechanic said, little to no gain in performance, all for aesthetics, problem is, with as far as I’m now going with the car, should I skimp out on this??? 
my personal opinion is, I love the Nismo plenum, but to buy one and cut it up seems…questionable.

If you're going to change it, at least go a Plazmaman or CPC not a Nismo one. Nismo "performance" parts don't really perform if you know what I mean.

(This is my personal opinion 🙂)

maybe a little…😆

The Nismo plenum only makes sense if you want a few key design elements like the longest intake runners you can fit in a factory ITB setup and the different intake runner designs to avoid leaning out cylinder 6 to some extent. A single plenum design like the Nismo as far as I can tell will never actually work perfectly at equalizing airflow between cylinders. Dollar for dollar it is a horrible upgrade IMO but I have weird priorities. HKS is working on a dual plenum design that may be more what you're looking for and will be single DBW throttle body.

He's still using the factory ITB, you're planning on chopping it to fit a single DBW TB which will affect the way air flows and distributes across the runners at partial throttle.

I’ve been looking at the nismo plenum but not for the reason most people want one

Something I haven’t considered, I am leaning towards getting the Plazmaman plenum.

I’m waiting to see if I can make it work first

In my quest to catch up to R32 25T, things are moving forward, more parts back from cerakote. Hoping to order the gearbox next week. 

All your cerakoted parts look great and it seems to suit a wide range of parts. I was thinking of having front and rear hoon bars, miscellaneous brackets, Apexi pod elbows, battery retainer bar and the ugly retainer that the throttle cable passes through done.

Do you think anything on that list isn’t suitable? I googled this for at least 60 seconds but most of the articles were about how it would improve the longevity of the assault rifle that I don't own.

That is all suitable, They can even do plastic parts, he showed me a fuse box cover from a VL he did, looked brand new. I’ve given him a few plastic parts, I’ll post them when I get them back. 

[Old man 32 GTR]

More parts ordered, more parts coming in, Nismo restoration! Pfft, got nothing on me. Lmao 

Also got brand new headlights. 
. 

Had the engine bay ceramic coated by my Detailer while it’s bare, came up a treat. 

[Shoota_77]

Full resto!

That engine bay is going to look amazing once all back together.  Are you doing anything funky like wire tucking, brake line redirection or anything else?

I’m getting Pro wire to do a custom engine loom to incorporate all the extra sensors, DBW etc, still haven’t decided weather I’ll delete the fuse box and run everything off a PDM. I want to change ECU to the Motec M150, just got to talk to a couple of people to see what my options are. 
I’m moving away from the factory plenum and will be running the Plazmaman. I’ve finally decided on gearbox and will be running a 6 speed getrag box. 
also contemplating changing turbo, I’ve bought a 68/75 turbo which has the .81 T4 open rear (I believe) 

considering changing to the Garrett G40 1150 using the .95 T4 divided rear . 
manifold I’m using is a 6 boost T4 divided

Hoping for a nice reliable street car, but am going overboard in some areas,  and I do know that, but… GTR life! Lol 

[Old man 32 GTR]

Well as my plans on set up change more then my underwear I’ve decided to strengthen up the bottom end of the motor while it’s out of the car. 
will be installing a PRP brace with billet main caps and 1/2 inch main studs.

will make final decision tomorrow, but will probably get the 7675 sportsman with 1.12 T4 divided rear with a proper divided manifold. 
At this stage I’m thinking (and this will probably change 10 times before the car is done) but will run the getrag for a couple of years and enjoy the car for street duties, then I’ll just bite the bullet and put either an Albins or Samsonas in it and do the track stuff. 
I’ve spoken to a couple of people I know who are running similar turbos, (both have 2.7, one running 7675, other 7685) and both say it’s not as laggy as you’d think, but crazy fast when it’s on. 🤔
