What is the best engine
 

I don't mean for a family sedan. I'm production sports car enginers.

If you had some crazy supercar sitting around with no engine, what would you plunk in there?

Ls2

It really depends on preference and what kind of car you're driving. In my opinion, since it holds up so well to boost, the 2JZ-GTE, from the Toyota Supra/Lexus IS300. People hit 1500 hp with them. Some people prefer different kinds of engines, the LS2 is awesome, many here would say a rotary. This mostly depends on pure preference though.

rb26dett for me

I would tend to vote on the...
 

...motor I thought elevated technology, engineering and design to the next level. For my money, it would be the 5.7 liter V-10 of the Porsche Carrera GT. IMO, outside of Formula 1, there is no motor out there right now that combines as much technology and design-thought that this one does.

The Merecedes Twin turbo V12 is sorta nice, those guys at AMG are insane and I love them for it! :)

I was thinkng the same thing. That engine is a brute!

I will be interested in seeing the mods available for the new M5 engine, that could be another contender.

How can you go wrong with the 8.3L V-10 in the VIPER...

But, I would go with the Vette engine also...

power of 4 rotor will be nice with a quad turbo for each rotor:)

The Porsche Carrera GT engine. I heard it light up once, it was like sex coming out of it's tailpipes. The only time the hairs on the back of my neck stood up. Guy drove it a few laps, it truly sounded like a race car.

Rotary, period.

If I had a car sitting around that just wanted an engine under the hood I would most probably get a 427 supercharged engine from Shelby. Light enough for me and pushing out around 750 hp. Not sure about the torque though. Either that or the import favorite 2jz-gte. If the car was built for track use I would put in a 20b rotary with a little forced induction. There are too many good choices depending on the application. Maybe you could give us a type of crazy supercar that's just sitting around and we could come up with some answers. Simply stating that it is a supercar leaves the door open to interpretation about what a supercar is.

For sheer engineering, I would pick ........... the S2K 2.0L motor.
What other production NA piston engine gives you that much hp from such a small displacement?

General Electric F110-GE-100/129 good for 27000lbs of thrust.

thats right its a jet turbine with afterburner :)

I'll go with the new Ferrari F430's engine for pure technological brilliance. After that, I have to agree with Nojooc on the S2000's engine. However, I have to admit that Honda is the only company who at any time if they choose to and at the snap of a finger can trump Ferrari's engines. But we all know Honda has changed somewhat from the good ol' days and is now focusing on increasing volume and products in a difficult effort to chase Toyota.

the VQ35 :)

GM LS2...would be my first pick at the moment, but if that is too much displacement for the given application, then I'll go with Mitsubishi's Evo engine (can't remember designation code).

Possibly a Renesis variant to replace the Evo, all depends on how the engine develops over the coming years and what can be done with it.

bentleys new f1 motor made of carbon fiber. yah i would have to get a reaserch team to make the gas for me. but its worth the 5 grand a week

Interesting read from HKS that at about 375 whp it needs some engine strengthening (rods & rod bearings). They said they could get more than 400 whp with their system, fuel management, headers & exhaust but that the engine would fail.

If it has to be the rotary, then how about the 3 rotor 20B ? RX Tuner had a few that were putting out 450-600 whp. NICE

I'd also take a look at the race car engines honda makes. I saw a few weeks ago a 3.5 v8 pushing 700hp n/a. Honda is really the only company I see capable of trumping Ferrari's prestige, but you're right, they're chasing Toyota at the moment. They are genius', VTEC is one of the biggest breakthroughs, and a lot of companies have since made their only similar system, but none come close to what Honda has produced.

Both Rover and BMW have surpassed Honda's valve actuation technology.

Until the LS7 is released in the coming months. :D

We can't get too far ahead of ourselves, but yeah, that does replace the LS2. Heard rumors of 500bhp, but we shall see.

And BMW's Vanos technology is every bit as good as Honda's.

Depends on the application. For example, I would take a Renesis-equipped Elise over a V-anything.

good question!!! but it's not ideal world guys.!! so... the very first question is .. is the engine we gonna put fit in the car or not..!! and the 2 qustion is.. do we have those money to purchase the "fantasy" ok .!! but if I have a car like ..!!!!! nsx.. sweet..!! yeah.. then I would put a 26b in there..!!!!! yea..!!!! that would be hell sweet..

:D I like that.!!!!!!!! or 4g6s(evo) may fit in too.1!! :p it's "blowing" my mind .!!

THE CHEVY 350 V8 deserves a mention just because it is or used to be one the best most reliable and widely used motors around for a long long time. It definitely had a good horsepower/ torque to displacement ratio. There is a lot you can do to that engine for a fairly cheap price.

Its no rotorary but it is a good motor none the less

You mean the SR20DET.... since the DETT designation was only reserved for twin turbo Nissans, such as the RB26DETT and VQ30DETT.

Also, Honda build the best piston motors, pound for pound. 'Nuff said.

Cosworth BD series as well as YB.

HP/liter doesn't mean anything. I'm going to have to go with the LS7, Renesis, the new V-10 from BMW, or the new 4.3 liter from Ferrari.

What do you mean it doesn't mean anything? Of course it does, the one with greater hp/liter was designed better as far as performance is concerned. I don't know exactly what you meant by this, but hopefully I'll see tomorrow. Thanks.

True.... it's all about efficiency. :)

I seriously hope you're kidding. There is NOT a direct correlation between engine size and/or weight, and the displacement of it. Larger displacement does not mean a larger engine. Sure, there tends to be a positive association between the two given the same cam setup, but we aren't talking about similar cam setups.

If you have two engines, one making 400 hp, one making 300 hp, and happen to be the exact same dimensions and weight, yet the former of the two displaces over 5 liters, and the latter displaces just 2 liters, who cares about displacement? Unless you are racing in some sort of series, where the displacement of an engine is limited, or you live in the UK, where there is taxes based on displacement (stupid rule, as many higher displacement engines get better gas mileage than those making similar power with less displacement), hp/l means absolutely nothing.

I wouldn't call a heavier and larger engine that makes similar horsepower to a smaller and lighter engine "better engineered", based meerely on the fact it displaces less. If anything, it's engineered worse, as it takes up more space, and ways more, but puts out less power.

Very well put. :)

Over a bimmer website that will remain nameless, they were trying to argue that by swapping a LS1 into a 3 series, you were ruining the car.

What they didn't understand that the LS1 weighed less and took up no more space then a regular inline 6 or even an S52 (E36 M3 engine) and offered much better performance and ease of modibility :rolleyes: (I think I made up that word).

Thanks.

Some people tend to think that the more it displaces, the larger the engine, which isn't true at all. The VQ35 Nissan makes is about the same size as an LS1 if I remember correctly.

I'm sticking with Honda's F20C. I wanted to go with the rotary, but the thermal efficiency is depressing. As for blown engines, I'm with the VQ30DETT, Nissan's newest monster.

-The formula one atlantic series 4age, 1.6L at 240 :D But that engine is not streetable, so yeah the s2k engine all the way.

:confused: What do you mean Nissan's newest monster?

The VQ30DETT is the old 300ZX/Fairlady 3.0L V6 Twinturbo.

As for the post originally made by Aoshi Shinomori regarding displacement, I think what he was trying to convey was that there is a greater appreciation of a low displacement/high hp engine.

The reference to performance is to do with the overall efficiency of the motor's design and has nothing to do with a correlation between a vehicle's performance and engine size.

I almost posted the same thing about the VQ30DETT..

but then I realized the fairlady 300zx had a VG30DETT.

not the same critter

but I thought the VQ twin turbo was going to be a 3.2 litre, making it a VQ32DETT?

you are speaking of the engine which will go into the new GT-R, right?

I may be mistaken. As everything about said engine is still speculation as far as I know.

True... my bad.

So how much do the S2000 and LS2 (in the 2005 Corvette) engines weigh? That's the question.

I would never refer to the VG-series block as the greatest engine. From what I know, I believe cylinders 5 and 6 have had trouble getting cooled, which led to problems on the track. Of course, this can be solved with the die grinder. :)

Anyway, the VQ30DETT is an all-dominant engine in the JGTC. Here's an example:

I must digress however. I think the best engine has to go to Toyota and its 1.5 liter hybrid engine in the 2004+ Prius. It's amazing in its own right, and it sets the bar higher for more fuel-efficient engines.

Got this from http://www.hotrod.com/techarticles/50638/index2.html:

1997 LS1 Weight (lb)* 459 (automatic) 503 (manual)
*These weights represent fully dressed engines and may change slightly depending upon final production configurations.

Someone said in the GM Inside News forum that he read somewhere that the LS2 is 15 lbs lighter than the LS1. Here is the URL: http://forums.gminsidenews.com/showt...0&page=2&pp=20.




Total engine weight for the 2.0 liter S2000 engine is 326 lbs according to http://www.hondabeat.com/article_details.php?ID=45.




The 2.0 liter S2000 engine makes 60% of the LS2's HP (240/400 = .6). However, the 2.0 liter S2000 engine is 67% of the LS2's weight (326/488 = .668; assuming the LS2's weight is 503 lbs minus 15 lbs = 488 lbs). In order to match the LS2, the 2.0 liter S2000 engine would have to lose about 33 lbs OR gain about 27 HP.


I wonder if the 2.2 liter S2000 engine weighs the same as or more than the 2.0 liter. The 2.2 is still rated at 240 HP but dynos side-by-side indicate it makes more than the 2.0. Still, even if the 2.2 weighs the same as the 2.0, it doesn't make up 27 HP.

Also, keep in mind, the S2000 makes less power for its size than the LS2. The LS2 is fairly small.

The LS2 engine weighs 482lbs in manual transmission form which is 15 lbs less than the 2004 LS6 engine in this discussion https://www.rx8club.com/showthread.p...&highlight=ls6. Note that in the discussion the LS6 engine is listed incorrectly as 458 lbs but that is really for the automatic tranny equipped Vette with the LS1.

The big badass will be the new 500 hp LS7 at ~482 lbs +/- 10 lbs which represents a 41% better power/weight than the Honda S2000 engine.

I wouldn't consider it too efficient if an engine with a similar size and weight could make more power.

Wow, who would have ever thought. Add in the amazing MPG and I'm liking Corvettes more now.

RB26DETT, VQ35DE, 13b-REW, 13b-MSP (RENESIS), 2JZ-GTE are on top of my favorite s. :cool:
