I’ve seen a lot of people spend hours polishing all the intake parts and everyone doesn’t port match the intake to the head. It’s like buying new wheels,lug nuts,high performance tires & not putting air in the tires. Your smoothing & blending for better air flow but don’t get rid of the ridge right before it hits the intake valve. It might even make you lose power from the turbulence from the air hitting the ridge of the head.
Every car is different the vq35de, head runners have nearly no casting marks inside of them. the manifold on the vq is its main chokehold for this engine platform hence why we usually port them and leave the head runners unported, you need professionals that understand the vq to port your cylinder heads on this platform because uneducated people go porting the hell out of there vq heads and end up messing up there displacement to where they actually loose alot of power, and at that point it really isnt worth it unless your doing a full engine build in my opinion. And if anything that small few mm of lip on the head runners will be more like a velocity stack when the heads meet the larger exit port pushing air faster faster into the heads making for better atomization of the fuel ⛽️
I’ve been doing a lot of research into air intakes and a lot of people have different options. Living in the UK, it’s very wet a lot of the time and my main concern is a cold air intake sucking up water. The Z1 motorsports one looks the best. Did you notice any real power gains from it and do you have any concerns with it taking on water?
It’s hard for me to tell if I’ve had any power gains from it since I’ve pretty much did all of the bolt on’s and got tuned at ones (but considering it’s just 3inch intake all the way I would think it’ll make a difference) but regarding it sucking in some water I wouldn’t be concerned since the location of the filter is pretty high up from the ground. You can also use a “sock” for the filter and you’ll be solid.
@@I._NED thanks for the quick reply, does the front bumper cover the filter? I ask because I’m concerned with rain coming in through the front grill, as I’m sure you’ll have heard, weather in the uk is miserable.
Hi bro I have a question for you, after installing the GTR injectors do you need chip tuning so the ecu can recognise the new injectors or it’s just plug and play and can you use the stock fuel pump or you need to upgrade that one as well? Thanks in advance! Great video!
You would need to get tuned otherwise your afr would be all over the place. I’ve seen people using stock fuel pump but i would recommend to get more efficient one.
Nice video! Would it be worth it install this plenum spacer on my 2005 350Z convertible with an automatic transmission? I drive conservatively, rarely exceed 4500 RPM, and the car already has over 120,000 miles on it. Thanks.
I'm about to port and polish a non rev manifold to replace the original rev up manifold instead of buying mrev2, with 5/16 spacer and a z tube. I'm considering about rebuilding front/rear brake calipers with new rotors and pads and paint them red and my car is 185k miles 6sp, still strong as hell Yours is only 120k miles, still low IMO.
They are larger injectors then stock, when you run e85 it requires more fuel so bigger fuel pump as well as bigger injectors needed to have all the benefits of running e85
I’ve heard ppl say the spacer on the rev up is a loss in power? Anyone else hear this? I’ve heard unless you are adding the mrev2 with it it’s useless… I have a spacer… do I just not put it on?? Getting dyno tuned for bolt ons soon.. so I Wana make the best of it
I personally don’t understand how more air leads to less power. Sure it can be more on the tuning side of things but I got ported upper and lower plenums as well as ported lower runners and when I added my 75MM TB with my plenum spacer everything came together to smoothly. I still got more tuning to do but to answer your question. In my opinion I think $120 blox is worth it. Test it out for yourself.
Great question. You’re on the right track. These vehicles are engineered to a relatively specific purpose, with some flexibility. For example, if the volume of air going into the motor increases, the computer will add fuel. BUT, only to its limitations. The guy in the video is off to a great start by upgrading the injectors, as the originals are limited. However, he NEEDS to tune now. The computer program for fuel and air management operates in a specific parameter range. The tune will override these settings and allow for more fuel in response to the increased air. If you don’t tune after substantially increasing intake air volume, you will run lean.
@@samuelw5072 since my comment I’ve added ported lower intake manifold and ported upper plenum, cleaned injectors, new plugs, new valve cover gasket, throttle body spacer and the plenum spacer, test pipes, nismo exhaust, full paint job, tint, new slave/master and clutch line, new clutch ( asshole didn’t machine the flywheel) and tomorrow I have my appointment with admintuning. Lol so I’ve spent about 7k in upgrades lol 😂
Interested in the injectors and throttle body the rest of the porting stuff is a complete rip off. You can do it yourself when you have the plenum off within a few hours easy pz.
Definitely one of the better videos on cars made. Finally get to see every little detail and exactly how to do it
I’m glad you’ve liked it!
I was just telling my fabricator the same thing. I feel like I'm right there, under the hood.

Hopefully you find the restriction in the turbo kit, update us on YT if you do! Car is sounding and looking good!
How are the gtr injectors holding up
Are the injectors any good ?

Very detailed, thank you ✌️
Porting that lower plenum, shouldn’t the head match the plenum?
It really dosent matter tbh for vqs our heads are preety free flowing
@@Lifeofshawnyg I meant the size of the opening not actually smoothing out the Chambers
Why can Noone make a 1 inch spacer
The gtr injector will they work for my 04 350z de not to sure if there’s a difference
They will fit on your de, it’s the same as mine
Awesome video!
What is the point of adding gtr injectors?
They are larger injectors then stock, when you run e85 it requires more fuel so bigger fuel pump as well as bigger injectors needed to have all the benefits of running e85
Where is the test drive?
In newer videos there is dyno tune a couple of drift events
How much hp did you gain from all this ?
I didn’t do dyno run without those boltons but it ended up making ~265 hp to the wheels
I’ve heard ppl say the spacer on the rev up is a loss in power? Anyone else hear this? I’ve heard unless you are adding the mrev2 with it it’s useless… I have a spacer… do I just not put it on?? Getting dyno tuned for bolt ons soon.. so I Wana make the best of it
Worth it for a non rev up engine from what I understand

I have a revup and with a z1 spacer, stillen intake and aam resonated test pipes I picked up 30 hp and 40 tq with a tune
Cool🔥🔥🔥
Interesting that they ignore location 12 and 17 on that bolt diagram. 🤦
how much are you pushing?
260 to the wheels
Did you get any hp out of that
Hard to tell since I’ve got dyno tuned after all of the boltons were Installed

Good video man, too bad whoever did you porting didnt take the time do it properly tho.
Did you notice big gains

How are the gtr injectors holding up
They’ve been good so far
So there legit ? Im trying to get some for my z to go on e85 wasn’t to sure on the eBay ones
