Arm chair analysis: smooth ports promote flow therefore air velocity...rough ports promote turbulence... turbulence is good for fuel mixture. So it's a matter of determining what engine likes what more...in this case we got fuel injectors so I think the whole mixing might not be as important
This job reminds me a lot of when I rebuild my 2/4 stroke dirtbike engines. Especially laying the new gaskets and torquing the bottom and top ends together. The small details are clutch for the proper fit and no coolant leaks! This video was done amazing. Thank you for sharing man. Most z owners are people I would not wanna sit and watch for 15 minutes on youtube...
Thanks for the help! Would like to note for others that you don't have to remove the coolant lines from the throttle body if you're just replacing the upper manifold.
Great explanation, great view of the bay/ area being worked on. I was a bit iffy about installing these myself but after watching this I have no doubt I'll knock it out in no time.
Any mod for this car is pretty much useless unless you go with a super charger or turbo The amount of money you will spend for bolt ons can be used for forced induction I only have test pipes and long tube intake installed then called it a day...left the nismo stock exhaust alone Has enough power for everyday spirited driving for me
This video is great quality. The lighting was amazing, your pace is superb. Had a question, some animal chewed my fuel injector harness, can it be removed/replaced without having to remove the fuel rails?
Another great video milan. The way you instruct gives me confidence to do the bigger projects. With ported manifolds, i would be thinking of forced induction of some kind - it just seems to make sense! If not, bigger cams perhaps - either way you have done an awesome job on the z.
Great and informative vid! Most of the other Z vid people I've watched seem to annoy me but you aren't cocky or annoying. lol Thank you for the great video...subscribing! Very well edited and well produced.
Thanks for sharing I want to do this to my car now lol cant wait for the dyno tune. The Z1 intakes supposedly make a decent difference. I heard you can diy the intakes and now after watching your videos I know I can get it done. Thanks bro
You are better off getting a 3" intake and bigger throttle body's on the plastic intake models. The Japanese are very smart and knew what they were doing when that designed the smaller ports due to Bernoulli's principle. Also a quality exhaust is a huge plus on Z's and the G's
Awesome video the upper intake and lower intake ported nice the one thing to help it breath better upgrade the throttle to bigger size and port the heads and port the exhaust as well and upgrade the intake valves to go with the ported heads on the cold side and hot side It's sounds crazy and money to do all of that u will see more power and worth it depends on the individual but I would
Hey Milan, bolts are NOT measured by head size but by THREAD size. Head sizes can be different for the same thread size. IE 10mm thread size could have a 14 or maybe 15mm head size.
Nice video bro thanks I finally built up the courage to port my upper manifold thanks to your video and a few other I'm glad I did after 5 mins I felt like a pro I subbed thanks
On the lower intake manifold, did you have to put and kind of gasket maker to hold the gaskets in place? Or do you just clean the old ones off the surface and lay the new ones in place.
I hope you measured the head ports. While this may help slightly and I mean slightly .... no point in more air coming in if the actual head ports are smaller and basically creates a bottle neck effect.
Bro don't use gas as a lubricant for the fuel injector o-rings. Just put a little spit on them glides right in no snags and no worries about premature o-ring failure.
Great content. I'm doing mine now but I have a question re lower intake to head gasket. The gasket can be installed with the ports on the gasket either tapering in or out. Which way did you do it? Really don't want to do it the wrong way.
question: as pertaining to removing the upper intake manifold...there are two nuts that hold the manifold down once removed and the rear end of the manifold is stuck on the rear bolt...after the nut is removed how do I get it loose...and not damage the plastic manifold..thanks
If you have the funds to get a tune, I would defs get one after changing any engine related part. To prevent wasting an excessive amount of money on multiple tunes, try to play out when you're modding your car so you can get one tune with every part installed.
@@Cheeseypoofs85 I guess I worded that incorrectly. It was at max timing already, 3in intakes made 3 whp over the factory timing with both tunes maxed out. There's actually a video comparison on here somewhere that shows exactly what I found out on the dyno.
So would you be able to drive the car without a tune for a while until you schedule a tune and nothing will happen because I was told not to drive with them before a tune because the motor will blow
Hello i have a crankshaft problème in my 08 350z since iam from Morocco and theres no way to find a VQ35HR arround. I managed to find a VQ37VHR MY QUESTION is can i put the heads of a VQ35HR into the short block of a VQ37VHR reading your thread says yes, i would appreciate your answers Thank you
Love the video and the project. Props to all of us DIY guys. Question though: doing it manually at home by hand... my concern is that you'd end up with slightly different sized ports just due to human error and "eye-balling it". I wonder if there is any way to measure each port to make sure they're as close to identical as possible?
I been having problems with my G35 VQ35HR, my coolant is consume to fast and my car have a stall episode, I check for leaks and nothing is posible the manifold gasket have a leak or so, this can be a solution? No leaks anywhere in the visual inspection and this is the last chance 👀
This is a good mod on the vq35de as well. If you take the time and do it right. Research it. You can find a lot of info and pics of ways people have tried if you are willing to google a lot. Also something else to look at is the performance shops and their ported parts to base your port job on.
Interesting video, however most tuning specialists I've heard of usually re-profile the intake and exhaust camshaft to accompany gas flowing (porting) the intake manifolds. Otherwise even after a "tune" the gains are minimal.
I didn't make any power with upper and lower ported manifolds, dyno proven unfortunately. I went with a knock off company lol. Even with a tune it made no power. Maybe it depends on who does the porting and if it's done right? The upper and lower manifold should be port matched with one another. NoTrigga and z1 are the best on the market.
@@v36vhri just got triggaspec ones ! :) the dude is pretty chill and explained everything very well prior to installing he also supported everything needed for install
I changed mine this morning on my G37x, car worked fine for about 3 hours but went into limp mode & shut off. Tried to start it but would not start only the fan would come on.. You have any idea what it could be??
Making anything larger regarding fluid dynamics is going to decrease your velocity regardless of how smooth it is now. The smoothness just decreases the turbidity of the fluid
How could anyone dislike this great video. Great instruction bro.
@EMAH MUSIC u missin the point of modding/ sleeper cars

What if youre replacing valvecovers ??
just installed the ported upper intake manifold. thanks a lot mate haha. keep up the good work
Any major difference?
Good clear explanation throughout the video. Makes a big difference in their types of videos where detail is key
I need to get me one of those ratchet drills.. I'm seeing these things in all the videos now and they look so convenient
I don't typically comment. But that was the best instructional I've ever seen.
Great explanation, great view of the bay/ area being worked on. I was a bit iffy about installing these myself but after watching this I have no doubt I'll knock it out in no time.
8:20 Everything straightforward until here. I still don't see the knock sensors and what is that long metal pipe in the middle??
this is a very clear and concise instructional video. welldone
Most detailed I've seen. Thank you for this
Glad it was helpful!
Any CEL from upper and lower manifold upgrade before tune? And does this effect how realiable the g37 will be?
Way too much work for 4 HP hahaha. Thought you need upgraded throttle bodies (enlarged) and 3inch intake pipes to get benefit from porting ?
Welcome to the world of NA tuning. He also has post maf tubes that make 1-2hp
Any mod for this car is pretty much useless unless you go with a super charger or turbo
The amount of money you will spend for bolt ons can be used for forced induction
I only have test pipes and long tube intake installed then called it a day...left the nismo stock exhaust alone
Has enough power for everyday spirited driving for me

Yeah us VQ guys are usually douchebags.
Question. Why did you open the lines if it’s already attached to the throttle body?
Thanks for sharing I want to do this to my car now lol cant wait for the dyno tune. The Z1 intakes supposedly make a decent difference. I heard you can diy the intakes and now after watching your videos I know I can get it done. Thanks bro

Are you Chrisfix’s brother? Because this video was immaculate.
Very nice. Did you also port match the gaskets?
Nice video bro thanks I finally built up the courage to port my upper manifold thanks to your video and a few other I'm glad I did after 5 mins I felt like a pro I subbed thanks
On the lower intake manifold, did you have to put and kind of gasket maker to hold the gaskets in place? Or do you just clean the old ones off the surface and lay the new ones in place.
Would sand blasting it be a good idea? Like it won’t mess up the size of the holes when the head gaskets are replaced?
Can also preform an air intake re learn using the key and pedal.
Thx bro. 😌🙏 I used this video last nite... It's a keeper.
🍻
On NA cars ported cylinder heades and bigger injectors are pretty much evrything that can make huge difference.
How was the shipping? Did they send the part first? Or did u pay core ? Was a little confused , want to order
Hey Jay, shoot me an email if you need some clarification.
milanmastracci@gmail.com
Big fan, I have a G37 and it's very similar. Can you show a video of how to clean the throttle bodies?
motorvateDIY has an awesome video series on this process, worked perfeclt on my G and its idle is pretty good now.
I wish my engine looks this clean😄
Did you have to upgrade any of the timing chain/tensioner components? If so, what & how
I hope you measured the head ports. While this may help slightly and I mean slightly .... no point in more air coming in if the actual head ports are smaller and basically creates a bottle neck effect.
Hey is like to know if you would need a tune right away or can you run it with no tune
Bro don't use gas as a lubricant for the fuel injector o-rings. Just put a little spit on them glides right in no snags and no worries about premature o-ring failure.
Dyno before and after? Flow Bench before and after?
Was this properly ported? I’ve heard over gapping the manifolds causes turbulence thus losing power
Who makes the black upper strut tower brace?
Great content. I'm doing mine now but I have a question re lower intake to head gasket. The gasket can be installed with the ports on the gasket either tapering in or out. Which way did you do it? Really don't want to do it the wrong way.
This also helps down the line if you do choose to go for boost, like I hopefully will be going for down the line.
Are you going turbo or supercharger?
question: as pertaining to removing the upper intake manifold...there are two nuts that hold the manifold down once removed and the rear end of the manifold is stuck on the rear bolt...after the nut is removed how do I get it loose...and not damage the plastic manifold..thanks
Damn im impressed with your videos brotha, going to be doing this to my g37 soon.
Did you feel a difference in performance with out a tune bruh , am interested
I wonder how much a difference ported manifolds on a VHR make on dyno… I bet ported heads bigger valves would go crazy
Would this be the same torque specs for a de ?
What are the gains to hp one gets for having these two installed?
The editing is glorious
Have you done the throttle body coolant bypass mod?
Lol what's the link to that ending instrumental? After installing them does it require a tune asap?
If you have the funds to get a tune, I would defs get one after changing any engine related part. To prevent wasting an excessive amount of money on multiple tunes, try to play out when you're modding your car so you can get one tune with every part installed.
Do you have to replace the gaskets I heard they are reusable
Do you need a tune right away??
Where did you get part ?
Man explanation is so damn good in this video thanks for it 🙏
Happy to help brother!
How much more power will you get
Please consider going with 3” admin intakes and getting a revup admin tune.
You’re looking at an average of +35whp with just the intakes and tune.
Not true. The intakes are not worth crap.
@@HorgretorGellantara 3" intakes have shown up to 22whp over 2.5" long tube intakes on the VHR
@@Cheeseypoofs85 have you been on the dyno and compared them side by side with no tune changes except for the scaling? Because I have
@@HorgretorGellantara what's the point of an upgrade if you don't tune for it?
@@Cheeseypoofs85 I guess I worded that incorrectly. It was at max timing already, 3in intakes made 3 whp over the factory timing with both tunes maxed out. There's actually a video comparison on here somewhere that shows exactly what I found out on the dyno.

Did you install all new gaskets for the upper plenum , lower manifold and the TBs?
I replaced the plenum gaskets, but if yours are in good condition, I suspect you can reuse them.
Did you had to bleed cooling system ?
Hello i have a crankshaft problème in my 08 350z

MY QUESTION is can i put the heads of a VQ35HR into the short block of a VQ37VHR reading your thread says yes, i would appreciate your answers Thank you
Any dyno graph gain power?
Not doing bigger injectors?
I don't plan on maxing these out for now. If I go boost, I'll just take the manifold out again. Nbd
How many horse power you gain from these manifolds bro
Can this go on the DE model?
Great vid, I am from Recife in Brasil South America, I think your videos are great let’s see what hp it will have with these ported intake manifolds
what new gaskets do i need to buy
How much power did it gain?
Does this give you any horsepower gains?
Not enough to justify all the time and work not to mention if you paid for a ported unit instead of doing it yourself.
I have a question... can i use that kind of intake manifold in another vq35?
I mean can I use the vq35hr intake manifold onto a vq35de ?
Daniel Argueta no because the HR manifold pattern wouldn’t fit with the DE lower manifold. I gotta buy a DE ported manifold
Daniel Argueta you*
Does it make sense to do this on a boosted 370z
Any little bit helps, right?
Love the video and the project. Props to all of us DIY guys. Question though: doing it manually at home by hand... my concern is that you'd end up with slightly different sized ports just due to human error and "eye-balling it".

What's the total labor hours for both the upper and lower plenums? I'd like to buy the parts from Z1 and have my mechanic install them.
According to Z1 site, 30 mins for the upper, up to 2 hrs for the lower.
Where can I get them both and how much? I live ontario
Great work Milan 👍👍👍👍👍

man i love when you Canadians say things like "out"
OOUUUWWWTTT
Where could i get a lower intake manifold like the one you installed
Z1 Motorsport
I changed mine this morning on my G37x, car worked fine for about 3 hours but went into limp mode & shut off. Tried to start it but would not start only the fan would come on.. You have any idea what it could be??
I would guess you need a tune!
You changed both?
Here do you get your torque specs from?
Great video, i actually emailed you, i dont think you ever got it
Great video! Thank you very much!
Thanks Michael!
Any hp gains between the two
No
Double no..
Hey bro how did you fix the rough idle??
You need a retune.
Check engine light?
How did you prime the engine?
Cycle the ignition multiple times. You will be able to hear the fuel pump turn on and pressurize the lines.
milanmastracci before you replied that is exactly what I did. Glad I did it correctly
do you use metric or standard sockets?
Metric
10/10 great video!
Glad you enjoyed it! Thanks Rodrigo
Make a quick video on how to use a torque wrench ??
how many horsepower does it deliver?
Depends on the other supporting mods. The more mods you have, the more power this will yield
Is that what z1 intakes are ?
The Z1 manifolds have a Z1 sticker on them where mine don't, but that's about it..
What year is your 370z ?
Making anything larger regarding fluid dynamics is going to decrease your velocity regardless of how smooth it is now. The smoothness just decreases the turbidity of the fluid
Great video thanks
Would this work for the vq35hr
Yes it would!
What does this help u for? For hp??
Yes 👍
if you had to guess how much more hp gane
How do you prime the system?
Cycle the ignition a couple times and you should be able to hear the fuel pump pressurize the lines.
@@milanmastracci thank you sir
How long did it take u to do all that
Couple hours and a couple beers, and you'll have yours done in no time! 👍
