Find plenums for your Z: tinyurl.com/y9... Make more power with these easy to install parts. Adding volume to the plenum allows for better flow to the front cylinders allowing for an easy way to gain power on your 350Z. Shown for VQ35DE
Love the videos! From what I've researched, a lot of the gains can be had when self porting (if people have the time) the upper and lower plenum + porting and gasket matching the lower manifold to the head. For the top, the neck appears to be a huge bottle neck so I guess smoothing and increasing flow there would help. So glad you guys are now pumping out content on RU-vid!
I have a 06 revup 350Z. Been doing some intense research on various ways to increase some horse power! However, too many mixed opinions out there so would ne nice if you guys could really put these various set ups to the test would be great! It would help make the best decision down the road! Looking forward to see a vid on this topic!!!
I have a revup 6mt 350z and MREV2 is a little pricy but I put the MREV2 and the 5/16th spacer, and the difference in power was very significant. It.s a must have for the revups its just a bit pricy.
FYI. An old 03-04 lower plenum and a 5/16 spacer on my 06 rev up did quite the job. Torque increased and pulled further up the rpm range. I probably lost top end hp but it was not noticeable.. The increase in torque and throttle response way out did the loss of top end hp. Also did the throttle body bypass to decrease heat. Total money used. $70 for the old lower plenum. $90 for a Blox plenum spacer. And $5 for the vacuum connector for the Throttle body bypass. Total $165. Did work myself.
unfortunately, they WONT dyno test all these options and show us the results as that will lead to them taking a loss at products they carry and sell due to lack of gains from the higher priced options compared to cheaper ones... 💀
Kinetix solution of having the cutout for the strut bar is pretty clever, I do run into issue with my strut bar rubbing into my plenum now that I have the plenum spacer, even with the washers it still does. So might have to get something like this.
I got dyno’d with a JWT pop charger and invidia Gemini exhaust and got, 268.0 hp & 228.2 torque. Installed the mrev manifold, 5/16 spacer and Osiris Tuned: 268.7hp and 247.3 torque. I don’t have the actual dyno graph, but I want to say I have about 30 plus torque through most the mid range.
Absolutely dyno them. Please. There’s a stack of us out there with 350z Peojects bouncing back and forth with this decision. It would be an amazing help to us.
Nice video. I would love to see you test them on a 350z with stock exhaust with absolutely no other mods. That would give a new or older owner a simple baseline to start their mods if the wanted to start with the engine first. Everyone usually starts with the exhaust (and there are first so many out their) I think a fair comparison is with a stock exhaust. I hope this factors into your decision.
Once you go half inch plenum spacer or bigger, I'd just get a forward mounting strut bar. Dyno testing can be costly and time consuming, it would be dope seeing more direct dyno comparisons against these parts.
The kinetix is a better improvement over the plenum spacer, not only does it keep temps lower but it just costs a 100$ more than the spacer so why not get it. Also looks better than the stock manifold
Few questions, What about the cosworth plenum? And Would it benefit me to use a spacer with the Kenetix V+ plenum?..... also.... just do the dyno! Everyone wants to know what the best setup is
Don't waste your money people. I ported and polished the upper and lower intake plenum along with the intake manifold with a Z1 Motorsports mail in tune. I felt no power gains what so ever.
Why not cut more off the runners? I've searched the interwebs and all of the mods are basically the same, remove sharp corners and blending. Why not remove the top of the runners completely and then blend?
It's 2 years on, and they still haven't done any testing (that's rather disappointing!). I realize the motor is not as popular as it used to be but ... these are still enthusiast's cars and there are a BUTT-LOAD of these engines out there so there's still a HUGE potential for business - especially since many have high miles on them and will need to be rebuilt? If I was to call myself a specialty shop for Nissan cars, you can bet I would do everything possible to make a name for myself and be THE EXPERT authority on them!? One more thing and I'm not bitching about it - just some constructive criticism: don't show us the guys face when he's describing the trumpets on the manifold(?). He could've just stayed behind the bench instead of walking over to the car? We barely got a glimpse of what he was talking about(?).
Please Dyno I have short headers on my z, people said they don't do much but I feel a good difference of course I have Cai ,and I did a cat back as well but left stock muffler it runs excellent
I have the vq35de in my 02 Pathfinder. Looking to get more power out of it (duh.) and want to keep it naturally aspirated. I was kicking around the idea of putting a snorkel on it to actually take in cold air. Thoughts? Thanks for the vid. Plenty of helpful information.
Dyno tests please. I've already got a spacer on my de and was going to get the V+ plenum but decided the almost $300 price tag was not worth the power gain.
If a VQ35DE engine can benefit from swapping its lower plenum with that of a Revup, ported or not, and especially in conjunction with a plenum spacer, why then is the MRev2 plenum only said to work with Revup engines? Why will the MREV2 plenum not benefit a DE engine if it improves airflow?
Test them all quit playin. What I wanna know is if you can use a spacer with the kinetix composite intake, If you use the spacer doesn't that change the space underneath the 6 studs on the factory upper intake?
The motordyne should be off the table because it's no longer in production. some other channels have reviewed it with a dyno and reported negligible games without Fi.
Does the top manifold help with the non rev up motors? I've read the only thing that helps is the spacer. I guess going to a composite manifold would help with the heat transfer. Other than that I don't think the non rev ups are helped with aftermarket manifolds
yes, depend on the type of power gains you want and budget you cant afford. The spacer is a cost effective mod for hp gans; but, I prefer the Kinetix Velocity Manifold since it gives the car better top end power without sacrificing the low end torque.
Sooo...heres my warning I bought a 5/16 spacer and it's not on my Z because it hit the factory strut tower brace. Bought spacers for my strut bar and the hood wouldn't close. Had to go back to stock sooooo you've been warned
Already done 5/16 motordyne spacer. I own same car DE engine. Helps and sound great. Mine is fully done and tuned by specialty Z. DO IT.... All mods done except headers. And as we all know. Hard job minimal if any upgrades.
I have that intake manifold on my z and it gives the car better top end power without giving up torque . I noticed after i installed the kinetix velocity that the car pulled harder above 5900 rpms and with the stock plenum with a spacers.
All that did was give me more options when I'm already confused give me answers and dyno numbers but I dont have a strut bar in my g35 ima go mf 5/8s like what is clearance lol
Hey guys..I want to increase Horsepower In my 350z 2008. i have 3k only. Please suggest the things i can do with this amount. What shud i add in engine? Plz help if u have a strong background in this area. I have ZERO knowledge in mods.
You have an HR, while the mods in this video are for the DE. If you're looking to switch up manifolds, you can get a ported HR manifold, or switch to VHR manifold. Combine that with intakes, exhaust, retune, and you should make 300 whp easy.
ImJustMe555 yeah your right. Motordyne claims on their website that if you install both the MREV2 and the spacer you get more power....but if it’s just an extra 5 hp, I’d rather put that $500 the MREV2 costs towards a tune.
I've installed the MREV2 and 5\16" spacer on a friend of mine's car and based on what's required to install them you might as well install both at the same time for the maximum gain and tune for that.
