Excellent! Keep up the good work!

Looking good chris! cant wait to see the prototype model! keep it up bro :)

the kit I can offer if everything works will consist of the following parts:

- GT-R plenum lower intake manifold adapter (as shown in the pictures)
- 2x 12mm custom fuel rails for stock or aftermarket injectors
- 1x OEM Nissan gasket for GT-R plenum
- 2x OEM Nissan gasket for 370Z head2lower_manifold
- all hardware needed like washers, nuts and bolts

optional parts:
if you want to keep the stock fuel system:
- adapter from the factory FPR to a Y-outlet block with 2x -6AN outlets
- 2x braided teflon fuel lines to each fuel rail with -6AN connectors

if you want to upgrade to a return system you can route two separate fuel lines to each fuel rail. On the firewall side of the fuel rail there is a -6AN plug which can be removed to convert to a true dual feed rail setup.

additional optional parts:
- OEM Nissan GT-R R35 upper plenum

we can even supply larger fuel rails with 15mm or 17mm if anybody wants to run very large injectors and needs it !

for pricing etc. I cannot say yet as I want to finish the prototype and dyno testing first and then have to calculate to cost per unit based on how many of you are interested in this special upgrade.

Something to keep in mind: is your test car ECU-tuned, e.g. w/ UpRev? The only other manifold option we've had (the M370) there's been this unresolved question forever that it makes gains on the stock tune, but if you dyno-tune before and after it may make zero effective gains, as the gains from the changes to the manifold seemed to overlap with the tuning gains somehow, at least for some 3rd-party testers.

I agree, comparing tuned before and tuned after is the best scenario for showing a part's true gains.

For example many air intakes see gains by leaning out an overly rich AFR, which they can control by their MAF tube diameter. An optimal tune would also typically lean out the AFR the same or similar amount. If you compare tuned vs tuned the results are not always quite as impressive.

Oh, and nice work ChrisUR. Keep it up!

Ipressive progress to say the least. Keep up the good work!

Simply amazing. Don't forget the need for new MAF tubes. I'm not sure how it will all fit.
