FUJITA vs JWT POP CHARGER & z-tube (An Apparent Design Comparison)

Ok, now, I am looking at purchasing one of these two, the prices are very similar that its not an issue. My main concern now is design, from what i can see (various pictures) is that the JWT has more components which direct more air to it.

1. The bit of tubing on top of the grill which pushes air towards the air filter, I believe this is even effectively directing air at relatively slow speeds, say 20-60kph.

2. Heat shield, this well "blocks" a bit of the ambient heat it also helps to keep the air which is being pushed in from the bottom "directed" at the filter.

The Fujita intake filter is positioned much lower then the JWT reasons why i think they did this was to get most of the air from the bottom (through the inlet in the bumpers) and the lower bit of the grill. It does NOT make use of a heat shield (can be fabricated but I am talking about out-of-box-design) or the tubing which sits atop of the grill.

What do you guys think? what I just said will have negligible results? Im just working from a design perspective to then help myself and other buy the apparently better product.

JWT keeps the standard intake tube..i personally would prefer the kit come wth a smoother one than the factory 350gt tube.

The fujita cai looks alright, once again i personally don't like the long design of the intake tube..could hurt throttle response, and let's face it...the drive by wire system already makes it slow, especially when the engine is at idle or near idle rpms.

I was running the HKS intake setup, found it to be brilliant. Recently went back to z tube + high flow panel, and the car has slowed down a fair bit. Those hks intakes are really high flowing with minimal resistance allowing the engine to rev much quicker but you pay the price in the filter element used (you can see specks of light if holding the filter element against some light source).

My 2cents.

guys, with either of these is 3/36 of 1/4 of fck all in power difference.

in regards to cold air partition, use one as hot air will send you backwards.

in regards to "ram air" effect. bugger all really, there is no big bell mouth, no massive air guides. Just a relatively free breathing air box.

in regards to changes in low down/midrange power, with a stock pre filter intake and being an NA the only bit that really matters is between the throttle body and the valves, so just the runners, these havent changed so bugger all there.

as for tube design... again, not much in it, but a smooth pipe will give a slightly nicer flow.

So if you want to make a difference (but it will only be tiny). grab the fujita pipe and a pod, build a cold air partition to totally seal the pod and intake from the engine call it a day.

Unless you plan to radically change the snorkel design INTO the partition your not going to see a huge difference either way.

Which one claims more power?

:(:P ...lol like your way of putting it. Yes, i DO understand there is "negligible" power gains unless you go into the really high

end enclosed units which have LARGE dedicated cold air feeds.

But im not looking at performance from these two units, more for the sound AND im looking at what's the best bang for my buck?? (Both systems are around the USD250 mark). Btw IMO, the rippled section on the tube is so small that the possibility of a circular air current being formed which then impedes in the flow of air is soooo minute, that's its not really a factor.

sigh...

believe what you will.

I've personally seen 0.3sec difference between my hks intake and panel filter/z tube from personal testing on my car and that's all my gonna say - people ask but no one listens anyways heh.

Touge, do you have any details on this HKS intake, please?

Are you selling your one?

Personally, I feel HKS filter is crap. If you look around in the web, you will see that they do let in a lot of dust particle into the engine.

Hey all just reading this thread, as i am interested in installing somthing similar in my v

After reading the thread and different opinions I was wondering if somthing along the lines of this?

this is a photoshoped mix of the:

Fujita intake

and

JWT

as they both have pros and cons etc

(also im just fken board with nothing better to do)

ideal.jpg

thats not too bad... would be even better if you could close off the gap between the end of the strut and the end of the partition.

yeh i think just going off wat other have said, if that was closed in would be the best of both worlds. keep in mind that picture is make belive i just mushed the 2 pics together lol

but its deinatly do'able if u buy the fujita intake and mod it slightly and make a fiber glass or similar sheild for it would be quite a nice lil mod for the 'v' both in preformance(even if it is ever so slight) sounds and looks imo

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
