Intake Manifold / Plenum Optimization Nissan 350Z & Infiniti G35 (Cerakote and more) | AnthonyJ350

This is my favourite Z channel because of the detail you go in to and think about all the little things most others wouldn’t consider. Engine bay looks super clean and I hope to one day get mine looking half as nice. Another great vid 👍🏼

[@AnthonyJ350]

Thank you so much for your kind words! Put the car through a good test today. 33 degrees Celsius ambient temperature, highway and city driving and the car had good pull, even with the coolant temp getting over 100 degrees Celsius. Cruising is would be around 90ish.

[@ryanlewis3496]

Absolutely Agree. Z’s are awesome cars. But they are very intricate. By that I mean so many little things affect the cars performance and drivability. I For example: t’s not like other cars where an exhaust upgrade provides the same result on every car. EVERY little thing matters on Z cars. And Anthony really takes the time to help explain that with his attention to detail.

[@1MADZ]

I actually chose to utilize the rev up manifold, then port matched the lower runners and plenum. Polished. Then re-tuned. My z DE revs higher so i could utilize all that extra flow up top. Its effortless to move now. Your next mod should be trying to get your hands on a 3.9 final drive. Believe me.....worth every penny.

[@AnthonyJ350]

I'm trying to decide on the final gear ratio. When you're cruising on the highway, what are your engine RPMs?

[@GreatWhiteStagea]

@@AnthonyJ350 60mph is around 2.7k RPM, I have 3.9 fd as well

[@GreatWhiteStagea]

@@AnthonyJ350 But yes, absolutely worth it.

[@AnthonyJ350]

@@GreatWhiteStagea OK good to know! So that'll put you at peak torque while cruising on the highway. Ya I'll end up putting that gear ratio in.

[@DEATHWISHVQ]

I did a similar video to this. I have thermal and plastic gaskets, my manifold is stone cold during winter and during summer I ran it on average speeds of 80-90 mph and my manifold was still cool. The only downside is when your turn off the car and park the hot air will lift from the chamber thru the intake channels and will cause the whole manifold system to be hot.

[@AnthonyJ350]

Thanks for sharing!

[@jerrywilliams6820]

I’ve done one of a kind build on my DE true 4 inch cold air intake all the way to bumper with the biggest 4 inch velocity stack USA green filter huge ass intake lol I made myself All motor build, cams, ported heads, pulleys, tomei headers exhaust, 14 pound flywheel and clutch, E85, ported polished plenum upper and lower, GTR injectors, aem fuel pump, NWP 75mm tb, modified upper plenum cut the bolt heads off on the upper sanded polished everything down and a 5/16 spacer with all thermal gaskets no heat soaking and sprayed the plenums down in heat resistant paint. Fully gutted car is under 2700 pounds. Gotta be one of the fastest 1st gen DE 2003 Z all motor around on the street if I had to guess

Hey Anthony! Hope all is well...I'm in the middle of knock sensor and harness replacement due to a rodent issue wich is handled. Anyway can you provide the torque specs on lower plenum, fuel rail, mid plenum and upper plenum...I know you are busy but you are the only one I trust on this matter...any advice will be apreciated. I have the torque sequence. Thank you and have a great holiday.

Hi there! I go over that in this video kzbin.info/www/bejne/bpzFlnaJobd3fZYsi=WWVLGNlGb_ct_Tlp

[@locophoto6881]

Hey Congrats! I've been following you off and on for years as a fellow fan and driver of a 350z...you've really come a long way. :) Just stumbled onto this video drawn in by the thumbnail seeing red valve covers....PLEASE....can you share where you got those? Would do that as well in a heart beat and the Z is leaking anyway so this will be one of the next things that will be done I think. Thinking the timing cover would look beautiful powder coated in that same red....like an old hot rod engine? A lot of work to get that done but a thought for a future upgrade if anything fails that needs that that timing cover removed to then have it powder coated..

[@AnthonyJ350]

Thanks so much for watching! I bought Concept Z aluminum valve covers and had them powder coated red for durability. kzbin.info/www/bejne/iKeupoWQr69mppY

Hey man, i love your videos! I got a question regarding your strut bar. I also got a plenum spacer and i got contact between the plenum cover and the strut bar. Did you lower your motor or dont you have clearance issues there?

[@AnthonyJ350]

I have Motordyne spacers on the shock tower brackets and a Cusco bar to get the clearance. You could probably just do the Cusco bar.

[@nightcoresmileyhd8157]

​@@AnthonyJ350 yeah i also got a cusco bar and a z1 spacer. but the motor is hitting the bar. Do you also have motor mounts to lower the motor?

[@crimsonsw21]

I like the way it looks and it does fit the OEM+ theme you were going for. Things I dont like are the angled spacer and the aftermarket strut bar. The aftermarket bars with pivot points are more for looks and not as structurally stiff. Personally I went with the Kinetix as I feel that even with all its flaws it is still better than the OEM setup + spacer for making power up top.

[@AnthonyJ350]

I wanted to get as much air to the front cylinders (that's why the angled spacer). Which Kinetix plenum top did you go with?

[@AnthonyJ350]

I also want good mid range power. As a touring car, that's where you're using the engine the most realistically.

[@crimsonsw21]

@AnthonyJ350 Makes sense, one of the things I like to tackle with my car personally is to improve on the car's deficiencies and the factory manifold definitely is one of them. I know the Revup and DE are slightly different and respond differently to certain modifications, I don't have any experience with Revup engines myself.

[@crimsonsw21]

@AnthonyJ350 I got the Velocity, although not an ideal design, it certainly fixes the balancing issue with the stock manifold. It gets a bad rep, but in reality, any time you see a DE near that 300whp mark or beyond...it will either have the Velocity or a stock manifold with the neck cut off and modified. The stock throttle body neck is terrible for NA power, they discovered that when doing testing at SG motorsports for the headers and intake that never happened.

[@AnthonyJ350]

@@crimsonsw21 REVUPs have variable valve timing on intake and exhaust. They respond really well to the MREV2 and a plenum spacer and develops really good midrange power.

[@robmcguire9756]

I take it you did everything on the top end I noticed that when you were taking the first reading there was a lifter making some noise and when taking the second reading the lifter noise is gone how much of a gap was in that lifter My z has a sloppy lifter on no 3 exhaust was it a hassle finding over size lifters. plus your engine look sweet

[@smoxch5444]

I have just bought the sikky gaskets to go between the block and runners, would you still suggest the motordyne iso thermal gasket over the sikky version? I already have the motordyne one as I got it with my plenum spacer and mrev2. Also what did you use to coat your plenum and would you recommend coating the upper, lower plenums and runners inside and out? I will be installing the Z1 CAI on my DE, would you recommend coating that in anything? I’m planning on wrapping it in heat resistant tape but was wondering if I should treat it with anything to prevent corrosion? I have had to modify the end slightly to fit my filter better. Finally some of the welds on the z1 intake are a little rough but I don’t want to weaken any of the joints, someone suggested using some jb weld to try and smoothen the inside of the tube out and I’m not sure if that’s a good idea or not. Sorry for all the questions. Thanks

[@AnthonyJ350]

I would do the Motordyne iso thermal. It's proven and it keeps the height down. It's coated in Cerakote and you can see in the video it runs cooler.

Hi Anthony, I notice at 3:30 onwards your engine has a bit of a knocking noise at idle (not injector tick). any idea what it is? Because my 06 rev up does the same thing. At first I was worried it could be slight bottom end knock but the motor runs perfectly well so I've just ignored it.

[@AnthonyJ350]

If you watch till the end it idles smooth. I changed out with VVT solenoids kzbin.info/www/bejne/jZ-4gJV_mdKsntE

[@mattman20132]

VQ boys performance has a "power pack" for the vq35de, both types. Its ported upper, lower, and lower manifold, all for 600 bucks. seems like an insanely good deal considering the motordyne mrev2 is over $600. do you have any experience with their work? I was curious to know your thoughts on them and if that would be a good route to go for some NA power.

[@1MADZ]

You'll need a tune for that. Their power pack, I did it all myself. Made tons of vids on that . If you don't have the time or tools to, then it's a good deal. I'd say fair price. Need a big 3.5" intake 6" filter plus 75mm TB. Good tune.

[@ryanlewis3496]

Well you have to remember (most people don’t know this) the MREV 2 is only and upgrade for RevUp engines. The standard DE lower plenum IS the MREV2 essentially. So unless you have a RevUp… you do not need an MREV2. So save your money DE guys.

Hi everyone!, just have a doubt, some heat the is produces kn the block is transferred to the plenum, putting an heat isolating gasket doesnt eliminates that partiañ cooling element and leaves the heat solely in the block, making oil suffer more heat?..
