87mm TB Project

Finally got about as far as I can take it without being on the dyno. MAF table needs more fine tuning, but I won't be able to do that until I get on the dyno. For the most part its done. As you can see from the video, there is no check engine light on the gauges.
mw9 is going to take some measurements and take my spare plenum and hack it up to custom make one to adapt all this. It will look something like SG's seen in the attached pic.
Here is the short video:

The intake manifold above is the kinda design I worked on for my my own car and this would roll to the driver's side and would basically be manifold, TB, MAF pipe and filter, the stupid road block is that the oil filler on the driver's side valve cover...
I never persued this any further than sketches, and the worst part is where I work now has a fab shop and I could totally get it made...
If I was to remake the upper plenum, I would cut the flange off and completely remake the top and kinda follow what you posted that SG had done.
No matter what you do, you are fixing a bad bottle neck

First off, please excuse my ignorance in tuning and sensor outputs.... but
In regards to the comment earlier in this thread about upgrading the MAF sensor to help with the 4" intake tubing, wouldnt a cheaper alternative to purchasing the GTM maf be to use the maf that was intended for this throttle body?
GM p/n 15865791
It also looks (I could be wrong) like the oem 350z maf
-5 pins
-card style
-flange style
But I could be completely wrong about this being a plausible alternative... just throwing the idea out there

Me too.
I have a slight change of plans. Im not going to build my motor over the winter depending on what compression is and oil sample comes back with. I need to pay off my truck and daily driver before I sink a ton into an engine.
So for sure getting long tubes once the plenum is done by mw9. I would like to see what kind of power it makes with that setup then add some street cams and see how much I improve from there. I'm expecting once the cams are added it will really open this thing up. I have some lightweight parts I want to buy along with some SPL bushings. All to be ready for next race season.
