Let me do the math here, and I'll get back to you on this later, but they would most certainly apply the same principle as the K and J blocks. Small displacement, high revving applications, but also higher displacement variants of the same block, with a lot more torque.

I suppose, if they did a square engine at 3.5L, they could stroke it up to 4.2 to 4.4L on a rugged high-torque application. But I'll do the calculations later and get back to this.

Point is, once they have the block done, the stroking of it is almost a small detail besides coming up with the block design.

~4.3L V8 is about what others are putting in cars.. i.e. LS430, 740i, A8 etc..

I just dont see it happening any time soon.

Ok here are a few possible scenarios based on a V8 Block that could rev to 8500RPM in 3.5L form:

In a square form, you get: Bore/Stroke: 82.5mm x 82.5mm =3526cc

The power curve of such an engine, built to similar specs as the K20A would resemble something like 400hp @ 8300RPM and 265ft-lb at 6000RPM (or <)

You could extrapolate from that block, seeing from what Honda does with it's K engines, a long-stroke, high-torque engine that could resemble this:

Bore/Stroke: 83.5mm x 94mm = 4116cc (4.1L)
Given that this engine was built to similar specs as the K24A2 it's performance would resemble this: 350hp @ 7000RPM and 285lb-ft @ 4000 (or <) RPM.


If you want to go with a similar configuration as Ferrari's 360 Modena Stradale, and go with an oversquare engine, here is what a 3.5L would look like:

Bore/Stroke: 84.5mm x 78.5mm = ~3510cc

Given that this engine would be built to similar specs as the K20A, that would give an engine that could rev to about 9000RPM, and could yield in the areas of 430hp @ 8600RPM and 260lb-ft at 6000RPM (or<)

If you extrapolate a long stroke engine out of this baby, you'd get something in the areas of:

Bore/Stroke: 85.5mm x 97.5mm = ~ 4725cc

This baby would yield, if built to similar specs as the K24A2: 400hp @ 7000rpm and 325lb-ft at or below 4000rpm.

-------------------------------------------------------------------------------------------------------

All this is to say that if you build a square 3.5L screamer, you could extrapolate a 4.1L stroked V8 out of it, and if you built it oversquare like Ferrari does wih the Modena, you could extrapolate as much as a 4.7L out of that given block, with the results accordingly.

All these values are NA, and needless to say, theoretical, based on the stretch of my knowledge.

I believe these numbers are feasible though, with the technology that Honda has with it's engines as of now. It would be nothing to add low boost and get to the 500hp numbers, or attain it via IMA, and get near-equal torque numbers as the hp values.

The main challenge would be to internally balance the V8 well enough to reach such high rpms, but given Honda's work with the K24A2, I believe it could be done for sure. We'll see.

At least, it makes me salivate to think of the possibility of this happenning.

Well, Honda surprised me. I had all but given up the idea of having an Acura to put in the mix when I get my next fun car. I had all but decided it would be a 997 GT3 but depending on what happens the Acura NSX replacement might be a very viable alternative.

I guess Honda feels left out of the new wave of GT-Rs and Supras coming in a couple of years and maybe decided to change the formula a bit.

Heck they might even have two versions of the car - a 400HP $60K car to compete with GT-R and Supra and an all out 500HP supercar at the current $90K level.

Yumcha

Well, I just read Car Magazine in the newstands and in this months issue, the full page report claims that Honda is indeed pulling out of the performance vehicle segment. The article continued about how the NSX (which was going to be based on the HSC), Integra Type R, S2000 Mk II would all be discontinued. There was mention that although the company has no shortage of engineers and designers who would love to make another iteration of a supercar, the senior members of the board (in Japan) have nixed the notion. Interestingly and not surprising, alot of the noise for a new NSX was made by the North American portion of the company.

All I can say is eek. This is too bad...

No one will make a v8 under 4.0 so why not for 4.0+(well it seems nissan is pushing v8's with their damn 4.0 v6's), its a huge market laugh or not. Honda revolutionizing Nascar(Pushrod) would push sales hard in the US, let alone it would give them a hard ass engine for Honda sut/suvs. Toyota has built their pushrod, will honda? Stay tuned.

Sarlacc

Mr. Honda himself was a racer and performance driver....his cars and bikes were all reflections of that. I serisouly doubt honda would turn their backs on their roots.

The various CEO's and VP's have said repeatedly that Hondas need to be fun to drive and recently have been too much like Toyotas. If anything CEO Fukui would be the enthusiasts' dream as he is an engineer who believes in the "Honda way".

Hey man, I'm not lying. I'm just quoting what I read?

Why is that so?

In that sense, all I-4's is a huge market laugh as well.

The Oracle said it would happen... he didn't say if it would be developed internally or not.

kurt_bradley

I also seriously doubt that Honda would use an outside engine in their Halo car. That would accomplish nothing for establishing a new brand image. Not only that, but Honda is the biggest engine supplier in the world. Why would they buy someone else's engine for their most exclusive sports car? That would be like Ferrari buying a Porsche engine for the Enzo.

Honda is the world's number 1 manufacturer of engines by volume. They know how to build a good engine so there's no point for them to buy and engine from someone else. Heck, people are buying Honda engines to use in their cars (a la GM and the Saturn Vue).

In return for GM getting honda engines, Honda got diesel engines from GM as per the deal.

That's too bad the NSX has to go! I just cannot imagine what the Tokigi factory might have pulled out if it did happen!

im not bs you im bs the writers

June 2005 will be the last production month of the NSX according to this German site:

But nothing is official yet. Stay tune.

gocubsgo55

its gone more than grow long in the tooth, there are VERY little people who would still go for one. It's been over. I love this car's idea soo much, it's an absolute shame they won't update it.

NSX-Tuner

Seems like there are some people (the one's starting these rumors) out there that want to see the NSX discontinued. Personally, I hope the NSX never gets discontinued, only redesigned from time to time with more power and new improvements.

These kind of rumors have been going around for several years now and will continue until either Acura/Honda really does discontinue the NSX or they do a major redesign. In any case, until Acura/Honda comes out with an official statement, I'm not going to give much credence to these rumors.

GreenMonster

I'm a believer that every car company needs a flagship... wheither it be a corvette, viper or NSX... H/A is always tight lipped about new models and redesigns, but I can't see them not having something as their flagship.

phile

I'm sure we'll see a new NSX.

AcuraGT-3

AS exceptional as a performer the NSX is
1. In Europe and Japan, no one wants a 90k Honda.
2. In America, no one wants a 90k Acura.

I take this from NSXPRIME, where I am a member
I remember that the NSX's philosophy was something like "the result of pursuing a dream instead of the competitors". I can totally feel this passion of the great Soichiro Honda from his once kick-all-butts NSX and his fleet of best in business motorcycles. When the old man was still alive, he would sacrifice some profits from his tremendous empire to build the best machines out there to win ALL bike races, Formula One, etc. With the decisions to cancel the HSC, S2000, and the mediocre F1 results, you just know the new direction of the company is to maximize the profit. From a business standpoint, these are good moves to make stockholders happy and secure future growth of the company. Honda will no doubt continue to be one of the bests in automotive industry building cars for the masses. Thank God the bikes are still the best in the motorcycle arena. I can see that the Honda company, now without the founder, will just grow financially. But Soichiro Honda's competitive passions for racing and innovations do not get carried on by his successors. I just miss that great man. OTOH, the Ferrari guys are doing a tremendous job in perpetuating that Ferrari mystique and racing success. Imagine Soichiro were still alive? He probably would have made the 1997 NSX a 3.5 L 330hp monster, a 2000 HSC with 400hp as a Modena eater, and a $150,000 2005 550hp Enzowho. Of course, the past 7 years of F1 were also won by Honda. That's what I would expect if he could continue to pursue his dream to be the best of the bests as he once was. Sure, the profit margin might suffer a little, but I think the company could afford to eat it too. And I am sure the European would have embraced and respected the Honda name a lot more and the resultant increase in European sales would help offset the projected loss of profit. Ahhh, all that what ifs........ That's what dreams are all about, right?

NSX-Tuner

Your statement "2. In America, no one wants a 90k Acura." is . First off, new NSX's can be bought for $79. Secondly, there are still a number of people buying new NSX's each year, including myself ('05 NSX-T). In fact, most new NSX's get sold before they hit the dealer. They are just plain hard to find being that only 200 are built every year since late 90's.

bigman

What Honda needs is something to battle the Vette. Why get a sub 300 hp car when you can have a 400 hp C6 with crazy torque to boot. The C5 handled on par with an NSX, the C6 and z06 outhandle the NSX all day. The NSX may be a looker, but it is aged already. And while the vettes never have awesome interiors, there is nothing special about the early 90's look of the NSX's interior. Also for 90k, you can get a decently equipped 911. Honda needs to stop with the all aluminum space aged shit and work on getting more power to less expensive car. If they do the suspension right, and keep the weight down a 350z range, but put some more damn power into it, they would have a winner.

It's sad really.

For that coin, I'd rather have a:
911 GT3 ($139,000)
SL500 ($131,000)
C6 Z06 (~$100,000)

Very nice list, BTW...

I'd also throw in consideration for a Lotus Elise and then using the spare change for an M3...

OMFG are you serious? The last time I saw one at a dealership I was still in high school, and it cost $70,000. That was back when the Vigor and Legend were new.
