Z1 manifold, any one running one?
 

looking for input on the manifold??

There is one problem. You asked if anyone is running one when in theory whoever is using them would be running two. You know V-6 requires two manifolds. The Civic boys use one.
Sorry mate, is 3 am and I can't sleep, so I figured I'll bump this tread to help you out.

I think he means the plenum:

Z1 VQ37 Intake Plenum Power Mod 370Z & G37

I have the Z1 manifold and it added some power. I dont remember the exact numbers but i believe it was around 3-5 whp. Its a good deal for the price. The biggest gains I had were from the Z1 headers though. Well worth the money.

I have it, but I added and changed a few things all at the same time before I updated the Uprev tune so I can't be sure of how much whp/wtq the Z1 plenum added :ughdance:

I have one also and I will be installing it this month w/ a retune. I plan to do a before and after dyno. I'll create a thread when I do.

How much torque/hp did you gain from the z1 headers?

I believe I gained 11whp and 10 wtq. I already had the plenum, G3 intakes, test pipes and Injen cbe as well as I was tuned so the gains were from the headers. I didnt see the gains until I got a retune with them though.

Looking forward to it ;)

Been thinking about this as well.

I will keep yall updated, the fuel pump, injectors, manifold and CAI went in, tune coming in a week we will see what she can do

What other mods besides all that? You bought larger fuel injectors because why? What kind of fuel pump, injectors and CAI? looking forward to dynos. :tiphat:

What size injectors??

MODS:
-motordyne HFC W/ short tail
-750CC injectors, previous owner says there 650 but due to the way they look i think there 750
-Z1 intake manifold
-AEM CAI
-walbro 255

tune
 

If you can run a higher fuel to air mixture in terms, you should be able to make more power

I'm running the Z1 Plenum & I can't tell cause I installed the Stillen G3, Motordyne ART pipes, Motordyne Shockwave (E370) the 34 row oil cooler, and then had it UpRev Tuned. I'm getting 319 to the wheels after my dyno. The stock headers are actually pretty good. Get the Motordyne stuff and the tune & if you go with the Z1 plenum, have it port matched with the bottom manifold & bore the throttle bodies out as well, I know the guy who is getting them done for everybody got some good gains. We have collectors cars bro, 2016 is the last year of the 370, & I've already had the Nissan Dealership call me several times ( and I got 3 letters, the last one said 15% above Blue Book value if they could buy it from me. Hell no, I got it I'm March of 2014 in a private sale for $23,900 ( no tax in AZ ) and it's the Coupe/Premium with every possible option except Nav, it's a 2009 7AT with 22k miles when I got it last year ( close to 30k now)- have the original window sticker and purchase paperwork, total was over $45k. I love my Z , will never sell it. Sorry for the long post, just thought I'd let you know what I got out of my mods & that the Z car is a wanted car now, A LOT of owners have gotten letters and calls to sell it to the dealership.
