why do so many people ask me if this car has vtec and when i say yes they can't believe it. usually followed by stupid questions like when did they start making them vtec's do people not realize this was the first vtec honda started with?
 
Wow, amazing. I would not even waste time talking to those people about the NSX.

I suppose a large portion of the general population does not like to read. If they only took the time to read the car mags instead of just looking at pictures, we would all be a lot better off!
 
On many instances I had kids in 'cosmetically-enhanced' Integras and Civics came up to me and asked me the same thing. It's amazing to me that these boys have little or NO knowledge of what VTEC really is or how it works, let alone knowing that this technology was first inc. in the NSX. Unbelievable.... sigh.

I compensate by added a "Type R" sticker. That makes the car go faster

The nsx is the first ACURA that had vtec, and the first use in the US. Honda was using vtec motors in Japan since early 88. Honda introduced vtec in 92 in the states.

***How can it have VTEC? It doesn't have a big VTEC sticker on the back .***

That sticker is good for at least 10HP... 15HP if you live in Los Angeles... and a whopping 20HP if you're in Glendale or Burbank.

Why short-change yourself? Buy a Type S emblem from Dali Racing and slap that puppy on your NSX's ass. Now you're faster than the R in drag strips.

That's the chief reason i took off the engine cover and painted the vtec letter on the engine! Ok ok, maybe not but i am now seriously wondering if that paint that i use is going to make my car heavier?

I have to laugh at the type of threads that are on this site!

Interesting by all means.

Ok, so where are all you guys hiding the chicks?

No, I mean 92. Engine code d16z6 - 1.6l SOHC vtec introduced in the 92 civic Si hatchback.

I hate to beat a dead horse, but the CRX SiR had DOHC VTEC in 89-90 before the NSX. The first Honda/Acura car in the US market to have DOHC VTEC was the 92 Integra GS-R, followed buy the 93 Honda Prelude VTEC.

Personally I dont really consider the SOHC VTECs even in the same catagory as the DOHC VTEC cars, as they use the VTEC more as way to enhance fuel economy rather than an increase in perfomance/rev limit.

mmm...

I have a Honda/Acura 1991 NSX that has DOHC VTEC!? What am I missing here?

One main reason for DOHC is to allow the spark plug to be positioned in the center top of the cylinder head. You will get a more uniform flame front, which will result on more HP. (that's the abbreviated story, it's actually much more complicated then that) SOHC will not allow that. You can get close, but no cigar.

But...

To say the VTEC in a SOHC was not there for performance, I cannot completely agree. If you vary the valve timing you will flatten the torque curve in the SOHC engine as well as a DOHC. So yes, maybe not is the same catagory as DOHC, but any SOHC engine w/VTEC will be a better performer vs. the same engine without it.

The other thing to consider is the cam arrangement is just one facet. There are a lot more pieces to the "performance" puzzle. You mention rev limit, which relates to having low recipricating(sp?) mass, and this is more a function of your rods/pistons and stroke, then the cams DOHC vs. SOHC

Jet, it's ok, you didn't hurt it. notice I said first HONDA in the US??...and above that my first response I gave the history. (jdm crx)

I'll repost my original reply below in case you don't scroll up:

That is incorrect. It was definetly used to increase performance.

True,

I did understand what you wrote, I was responding to jetydosa's post, that is why I responded with his quote

I would just say: Well I did an engine swap with the prelude because I wanted the vtec system for high RPM racing.

Larry,
I understood what you meant, I meant the 92 GS-R was the first Acura besides the NSX to have DOHC VTEC
biggrin.gif
. Sorry I didnt include that.

As far as SOHC VTEC, I still dont really consider VTEC's use in those applications to be for a performance increase, more of an efficiency increase really. I mean the the 91 Civic 1.6 made 108hp and only went to 125 in 92 with SOHC VTEC. The DOHC VTEC 1.6 (B16A) makes 160! This of course is different from VTEC-E (which is the total fuel economy version used on the Civic VX/HX). Also, all of the DOHC VTEC engine cars have a redline of at least 7500rpm, and have the "rush" of top-end power that most people equate with the VTEC "kicking in" both audibly and seat of the pants wise too.
 
jet,

I now understand what you meant. I guess what I am really trying to say here is that I do agree that the VTEC DOHC engine are more performance oriented, but I just do not feel that the DOHC is the only contributing factor.

In other words if you took basically the same engine design, went to two cams, all else left alone, you wouldn't see the kind of gains that are representative in the HP comparisons. I think a SOHC cam engine can also rev to 7500 RPM if you lighten everything up.

That is my only point.

Again, JMO!!

so let me get this straight

HONDA introduced vtec in '89 in the states
in the CRX r

ACURA introduced vtec in 91 in the states
in the NSX

but Honda was using vtec motors in Japan since early 88

Oh God, here we go. I can't overstate my frustratrion when someone starts using Acura like it is it's own marquee. The NSX was developed as a Honda and remains a Honda everywhere in the world except in "brand-name-responsive" America. For the sake of simplicity, can we pretend that all Acuras are Hondas? Maybe this would eliminate some of the confusion on this thread in particular.

And for your info, a sticker can only add horsepower if it is JDM.

Nope. The CRX SiR model mentioned above for '89 was only released in Japan, not in North America. The first VTEC car released in North America by any division of Honda Motor Company, Ltd. was the '91 Acura NSX.

Nope again. The Acura brand is used in the United States, Canada, and Hong Kong, and all three countries (or whatever you call HK these days) sell the NSX as an Acura.
