I just wanted to share with you guys what I stumbled across on Ebay:

http://cgi.ebay.com/aw-cgi/eBayISAPI...item=593398814

Guess he found an untapped market for Vtec emblems. hehe

 

Thanks for the info!

I just emailed the guy, he said he would sell it to me for 14 bucks. The sticker looks very good even in picture. I might just buy it now or wait for the bid.

 

Well, Nissan does have a VTEC-ish system on the SR20VET...

 

It would be very stupid looking "in my opinion" to see a Vtech sticker on a Nissan. Just buy a Honduh! What's the matter with people.

 

Doesn't the maxima vq have a vtecish system in that it engages different profiles for different rpms? I could be wrong...

 

I think you're talking about the dual-stage intake manifold on the 5th Gen's and the variable capacity muffler that Nissan uses.

The 2002's 3.5L VQ has "VTC" which is "Variable Timing Control" - Nissan's name for VTEC. I don't believe previous VQ's have any sort of variable valve timing system, but the new 3.5 VQ is the first, I believe.

 

The Japanese Nissan NEO engine has VTEC.

 

 

yes some cars have vavle timing control but honda is the one that made if famous and when you think of vtec, you think of honda. so to put that on a nissan would just look retarded. but then again, its just my crappy old opinion.

 

i thot we had vvt? variable valve timing? and toyota has vvti variable valve timing intelegence? or am i just misinformed?

 

you are correct but thats not the point. most cars have some form of vtec but "honda is the one that made is famous and to have that on a nissan would be retarded" and thats the point...ok?

 

kinda like the VTC from the VE30DE? i've asked this before (while ago) and i'll ask it again..will the VTC in this new VQ go bad like the ones in the VE did?

 

I had an old H22A1 laying around from my honda days...
So i decided to swap the cams, ecu, and vtec solenoid into my VQ30DE and guess what...
With a little machine work it all fit like a dream....
I bought an APEX'i V-AFC to control the VTEC and it now kicks in at 4500rpm...
I picked up 20hp at the wheels between 4500 & 6500 rpm...

If you want to know the specifics on how i did this...
Email me at My4DSC2000@aol.com.

 

Okay let's clear some things up (I hope)

Nissan's VTC system first appeared in the 300z TT and the VE30DE powered maximas(in the usa) in about 1992(se maxima in 1992 anyway) The Q45 later also got the VTC system. This system advanced/retarded the intake cam according to rpm/load/temp/gear(I think 1st was locked out). This system was available in Japan either at the same time or before. But I believe it was available on more car models.

Nissan also has varible intake length/volume control also. This is a flap that varied the intake manifold area for better intake charge velocity. Good for low rpm throttle response and high rpm breathing.

Honda's VTEC is different than Nissan's VTC. Honda's system uses varible cam LOBE profile tech. One set of cam lobes for low rpm and another profile for high rpm. Up to now, it's only been intalled on the intake cams(except for the nsx I believe). This system did not advance/retard the cam timing at all(except for any differences in the low/high cam profiles themselves) With the advent of iVTEC, Honda now has dual cam lob technology and varible cam TIMING all in one. I don't know if they are featuring this only on the intake cams or not.

 

If they do, Jeff92se will have to become Jeff02se so that he can always have a Max that ticks INCESSANTLY.....

 

The VTC is not a Nissan version VTEC, it doesn't work nor try to be a VTEFC. Though, Nissan already has its own version of the VTEC in Japan. In fact, the technology was not very new. It is much older than the VVTi. It is called the NEO. It operates and gives result like the VTEC.

 

Ah did you even read my post? I don't see how I could have been clearer about pointing out the DIFFERENCES between the two.
"""Honda's VTEC is different than Nissan's VTC. """

Which Nissan in Japan had dual cam lobe profile technology(which is VTEC??) I already know VTC tech existed in Japan in 1992 and probably prior to 1992 in Japan only cars. Probably why I mentioned it correct??

 

Jeff92se being challenged on VTC knowledge....yeah that'll be the day!(j/k) *bows before VTC Master*

 

Hehe. Da-Max. Always good for the back up. LOL.

Hey, in reality, I would love to learn that Nissan had VTEC in Japan or something. But I seriously don't think they did/do/or will plan to.

 

i think that VTEC and VTC has hurt my brain, but thanks Jeff92SE your definition made the most sense.

 

Just to clarify another fact, while the 3rd Gen Max's SE had VTC..the current Maximas with the VQ engine DO NOT have VTC or any thing similar to it.

The 5th gen has the variable flow muffler, but that's about it when it comes to 'variable' stuff right?

 

The new 3.5L maximas should have:
1) The varible back pressure muffler(ala Y2k maxima/skyline etc.)
2) The dual stage intake manifold.(ala VE/VG etc.. maximas)
3) Some kind of cam advancing technology on at least the intake cams.

2) and 3) I could pretty much plainly see from the pictures I saw up on this board. Now I really doubt Nissan will use the same type of mechanicals as the VE(that would be extremely dumb!) But it will advance/retard the cam timing. I could even be a more advanced version like an infinitely varible cam timing technology. This would help w/ emissions AND greatly help w/ hp/torque.

 

No. Nissan already has its own technology called NEO. This has the same function as VTEC. It was first used on the Skyline 25GT sold in Britain and the Skyline 4 doors 25GT.

And no, not all Nissan has it.

click the link below. All 3 VQ Neo engine. 240hp with just 3.0L V6.

 

well, they do have what they called CVTC - continuous variable timing control.

However, I don't see any significant increase to HP because of that technology. HP tops out at 240 PS (Japan-spec), which is around 225-230 HP (S.A.E.). Too bad that I didn't see the chart there. According to the Japanese explanation of the NEO Di technology, the NTD & CVTC will increase low to mid rpm performance. I.e. flatter torque curve.

 

...I can't believe no one brought up BMW's Double Vanos system!

And Jeff92SE is right, Honda's VTEC is different from Nissan's ticking VTC; however, it's very similar to Nissan's Neo VVL, found in some SR series engines such as those in the Pulsar hatchback and the X-Trail (both JDM only). Also, the Skyline's RB25DET engine incorporates VVL technology.

Keep in mind that cam-phasing technology (Toyota VVT-i, BMW Double Vanos) is different from cam-changing technology (Honda VTEC, Nissan VVL). Some engines incorporate both (Porsche Variocam Plus, Toyota VVTL-i)! I think this is what Jeff was trying to get at, except all the acronyms got in the way.

 

I agree. BMW technology is arguably the best. Example? There is no better auto tranny than the BMW 3-mode steptronic. I'd get over not having a manual real quick. And for all those who are about to flame, go drive a 750iL first. Also, xenon headlights that everyone tries to imitate were pioneered by BMW.

Also I remember reading in a very old issue of Motor Trend that the only '92 SE engine w/ variable valve timing is the manual, not the auto. Am I right?

 

Holy freaking christ. No it's not the same thing. If you can't understand by now, forget it! 240hp from 3.0 liters ain't crap! BMW gets 300hp na from their European 3.0 liters.

 

Actually I think it was Porsche, in 1995 when the 911 Turbo came out with them.

Oh P.S.

Austin J/K

 

No Jon you are wrong!!!!!!!!!!!!

J/k but I know for a fact it was BMW, in the 750iL, in the early to mid 90's.

 

for anyone that doesnt know all the vehicles made now have there versions of vtec because honda/acura no longer has there patent on it there patent was a 10 yr pat. and there 10 years wa up so now all the other auto. manufacters can use it like the new celica (vvti)with the same basic motor in the IS300 and the new sentra 2.5 is a version of vtec. so are most other man. I read this in a magazine in a write up on te new sentra so dont flame me!!

 

Wrong Tilley, (vvti)with the same basic motor in the IS300

Where did you get that, the only thing they share is a vvti setup. One is a I6 cyl. 215HP, the other ic a 4cycl. I 180HP for the GTS They are not even close to the same thing, unless larger, different drive setup and two extra cycl. don't count?

 

Sorry I meant to say they had the same basic design for the vvti just to show how many different brands took after the Vtec.

 

introducing the new 2003 v-tec maxima with 400 HP. thanks to v-tec it has 395 torque.
