- Sup guys back again with another under the influence video, i apologize for all the verbal errors on some of the parts mentioned in this video. However, never seen any video on youtube on what modification is needed on the HR rail to fit the VHR rail so i decided to make one real quick, hope you guys like it! Comment like and subscribe, peace!!

This is literally the video I’ve been looking for
Norcal Nisbros hope it helps bro! 🤙
Dig the Z man! Will be waiting for the next Z update.
Thank you sir! Ill be posting again soon👌
Have you dynod it since?
I have someone in my town selling both VHR upper and lower for $185 which he lowered the price from $400. So I'm wondering if it's really going to be worth it? I mean that price is kinda too good to be true but sometimes you never know. Is there a way to tell the HR and VHR upper and lower apart from each other?
So besides the fuel rail the upper and lower plenum just bolt on no need to custom the lower plenum
Thats all you need buddy. Upper/lower/fuel rail, and bend the HR line to fit the VHR rail and your good🤘
Could I put ported VHR upper and lower manifold on my HR? Bc I wanna make good power and if Ima get VHR plenums might as well get nice upgraded ones
Yes, thats what im showing in this video.
Is the vhr fuel rail necessary for the vhr upper & lower manifolds upgrade onto a 350Z HR?
Yes, HR fuel rail wont bolt down to VHR lower manifold.
If I wanted to go bigger injectors would I have to look them up at 370z injectors?
And would I need to get 370z throttle bodies?
@@LorenzoG187 The throttle bodies are the same, and you don't need to change injectors for fit. However some people do so duty cycle isn't maxed out. Obviously you need a full new tune if changing injector size.
Thinking of doing this on my HR. Did you get a noticeable benefit compared to ported HR upper & lower? (after retune)
I got another 6 whp, however that was with the addition of PPE longtube headers. I had test pipes on stock manifolds prior. So after the 370z upper/lower ported plenums and PPE headers the difference was another 6 whp and top end power went from falling off at 6900rpm to holding max whp all the way to redline at 7500rpm. Your combination of parts and tuner will yield different results as well. Car is at 320whp/267torque. Stock cams, stock drivetrain.
@@projectzs1993 wow, only 6 with PPE? However 320whp is crazy with stock cams. Are you running e85?
As far as the chr manifolds, how was the torque difference? ie was it less torque down low, more power up top or more power through out?
@@ryanscanlan9875 yes only 6whp gain, however the PPE’s really cleaned up the graph and torque kicks in quick and top end just keeps going. Im sure if i had another tuner that “pushes” the limit for clout #’s it would of made more. However, im happy with my tuners been with them for a long time, my single turbo kit actually comes in today so the PPE’s will be for sale.
@@ryanscanlan9875 and yes on the E85
@@projectzs1993 Amazing - r u going rear mount or boosted performance mid mount?
Torque for lower plenum? And the car turn onn with the gtr injectors with no tune? Thanks for the video
First torque sequence is 5ft-lbs in a cross pattern, then finish it off at 19ft-lbs.
Idk about turning on with no tune, i already had the email tune sent to me for the specific mods so i had no issue there.
Get a email tune once you finish your mods, especially bigger injectors to be on the safe side👌
ProjectZs and for the upper? Ok looking to this to my car this week I wanna see ur whp waiting for that video.
@@luis_z3354 per the fsm 8ft-lbs starting with the center bolt working your way out in a cross pattern.
I havent done a video because the gains werent much as far as peak power goes, only 6whp. However, the torque comes on sooner and the hp holds all the way to 7700rpm with the VHR manifold compared to the HR dropping at 6800rpm. The car did gain more power throughout the rpm curve but only 6whp peak with longtubes and the manifolds, HR oem headers already well, test pipes ofcourse help which i had so didnt expect to gain much peak with longtubes, i did it to try and get the most out of the HR, along with the VHR manifolds, main difference is the HR now holds peak whp all the way to 7700rpm. Makes it really fun beating some 5.0’s, 392’s, evos sti’s etc..Ill post more videos soon👌
Did you feel any substantial gains from this mod . I have a G37s and I am very interested.
Its a bigger upgrade for the HR motors since the HR plenum isnt as good on top end as the VHR plenum. So you will get gains doing both upper/lower, however its up to you if you want to spend the money or port them yourself.
@@projectzs1993 thank u bro
What’s the difference on the 370z upper and lower bro? I have a ported lower hr and upper vhr but the hr and vhr look identical
The upper is what makes the difference in top end, you need both VHR manifolds and fuel rail to make it all fit.
We're you able to still use the stock HR injectors with this 370 upgrade?
HR, VHR or GTR injectors fit just fine👌
@@projectzs1993 what year of 370z do you have to find to fit you HR ? My Z is a 2007 roadster so what used 370z do I take from?
@@divahairline Any 370z/G37(VHR) plenum will fit the HR model, but you also need the lower plenum and fuel rail so it all bolts up correctly and modify the fuel line like i do in the video. One other note, some intake manifolds come with longer bolts, mainly the newer models, so if you get a used plenum, make sure you also get the bolts it came with.
@@projectzs1993 what year is your Z and what year 370 parts did you buy?
@@divahairline my Z is an 08 and i used 2010 370z UPPER and LOWER manifolds + fuel rail.
Where u get the little filter bro
Conceptzperformance 🤘🏽
Would I have to get 370z throttle bodies? And if I wanted to go bigger injectors would I look them up as 370z injectors?
No throttle bodies are the same i believe, i have HR throttle bodies and fits like oem. Might as well get GTR injectors and run E85.
Did you have to get new injector clips mine won’t go on because it’s turned and not straight out
I figured it out bro you gotta turn the clips to lock differently or just buy bigger injectors that don’t need clips
Not quite sure what you are saying, when i upgraded to 370z manifolds and fuel rail, i also upgraded to GTR injectors and i believe i used the injector clips off of the HR fuel rail. Everything fit fine for me.
@@projectzs1993 what about the back metal hoses that also go into the throttle bodies did you take them off the hr and swap them over to the vhr?
@@F30caleb the metal hoses that go into the throttle bodies are coolant lines that run hot coolant through the TB’s to help them function during colder weathers, but are a common delete for HR’s. I have the delete on mine where i re-routed the coolant lines so i have nothing going through the throttle bodies. With that being said, the HR and VHR should have a similar throttle body coolant line system. It can be deleted and re-routed or hooked up the same way.
Would this work on a de motor
No it wont🤷🏽♂️
Damn i was just thinking of going with Ported Upper/lower Hr plenums but looking at the commenst i guess you get the same gains with both right? But just with the Vhr Upper/lower plenums it holds power until Redline? I think the 6whp you gained was from the PPE Headers and not so much the Plenums but idk really haha i only say that because 6-8whp gains is what i usually see from longtube headers
I would agree on the 6-8whp gained from the longtubes, the plenums VHR plenums i believe help keep peak power until redline. Combination of parts also makes a difference as well.
@@projectzs1993 Yeah might have to go with the Vhr plenums and Fuel rail tbh as it would definitely help keeping Peak power all the way to redline. Ive been tryna find PPE Headers but they are like impossible to find now 💀 i can get Isr longtube headers easy lots of people here in Cali have them but PPE Headers are just so difficult to get a hold of now haha. Any chance you selling yours or know anyone selling some 😅😂
@@DaytonaBlueHr i actually will be selling mine, i have a single turbo kit that im going to install and it requieres oem style manifolds so ima have to remove the longtubes and put up for sale. Here is my IG i finally created one, “_projectzs”
@@projectzs1993 foreal you are 👀 i will buy them immediately once you do try and sell them 😂 ill follow you rn 🙏🏽
I’m about to do this swap.. will the car start without a tune before I take it to get tuned
Yea you can run it👌
