Lexus LF-A = V10......this car is a representation of toyotas F1 efforts...Stupid fast, Stupid expensive...I think toyota wants its lexus brand to compete on all levels with European vehicle manufacturers, luxury and speed.

As for a new supra.......i'd love to see one next year, but ive lost all hope right now. If it does come, its forgone that it wont have a 2jz... this engine is legendary, but face it, its a dinosaur and will become extinct soon. Get used to it. If this car comes, likey it will share its engine and platform with an IS coupe (which would be a shortened IS, which itself is a shortened GS) to make it a viable financial decision

I would love to see it debut with the 3.5 v6 (with a G series head, tuned to about ~350hp), Gorgeous bodywork (2000gt cues, trade mark round tail lights), Targa top and around $26-30K.

But i guess if wishes were cars, then every jack and jill would be rolling around in supercars and luxo barges

 

i agree with the 2jz comment. sadly, that engine series is history now *moment of silence*...

but seriously. 3.5 liter 3GR-GSE. now that would be a bad-butt base n/a engine for a future supra.

 

i6 and v6 are dated platforms guys -- things have to change -- the v8 will have a lot better performance gains -- its over...just live with it

new skyline will sport a 3.7-4.0L 400-500hp twin turbo v8 -- supposedly---

so just say good buy to the 6cylinder days -- its the future -- stop living in the past heh


later

 

V-8's are more expensive, heavier and less fuel efficient. Inline 6's might be going out, but V-6's will be around for a while still, at least if we would like 'affordable' sports cars. *supposedly* the new Skyline will sport a V-8 OR twin turbo V6... a V8 twin turbo was never mentioned nor is it likely (though certainly possible.......but with a target of 450-500hp why bother??). Performance gains of a v-8 over any other V cylinder configuration is arguable, it depends on the displacement, not only the amount of cylinders (though there is no replacement for displacement).......then you have to consider rising gas prices, development costs, the fact that V8's wont rev as high (though you certainly might not need to..at least until serious mods come) etc... see where i'm going with this??

Oh and 'justanotherasian".... moment of silence granted. If my physics arent to rusty, I figure that this engine could be tuned to about 330hp actually using a compression ratio of 10.5:1, that is one point lower than the current engine, leaving more flexibilty for aftermarket or TRD turbos ... (11.8:1 ratio in the is350's 2GR-FSE.... one with a G series head would be 2GR-GSE, as a 3GR is a 3.0L engine).

 

V6?!? you cant possibly have supra without an inline engine. RIP 2jz =[

 

The only company right now sticking with an inline6 engine is BMW and even those are soon likey to go. Ive already gotten used to that fact that if a Supra comes out, it wont have an inline6 engine (harsh reality........but the future is at hand). Hey, at least its still 6 cylinders....
wont it be odd if new generation supras actually came out and 2 or 3 generations from now every one is crying about the 'legendary2GR-GSE' and bit#$&ng about why we have to use fuel cells and hydrogen powered v12's or 6cell battery hybrids instead of a v6??? lol

 

............*dreaming* 1350kg (~2900lb) kerbweight, 330hp 2GR-GSE engine, getrag 6speed maunal, drop dead gorgeous body, carbonfibre/fibre glass targa top, wicked supsension and.......................... an off switch for the VDIM ***** wakeup!!! wakeup!! damn u.......

"Santa, can you make toyota grant me my one wish?"
[santa--shaking his head] 'Sorry son, i do christmas, not miracles...'

[on my knees] "Jesus, can you make the execs at toyota greenlight a new supra and let the designers build it the way we want?"
{Jesus.......points.......laughs..........hysterically} hahahahahaha...

*runs to the corner to cry*

 

im a big fan of the supra but thats just a cadilac XLR

 

huh?!?!? are you posting in the right thread??

Say it with me......."pot is a drug...smoking is bad....

 

thanks for the correction again yeah... it was either 3gr or 2gr in my head, didn't bother to look it up myself (got caught by you twice now. haha). and i agree with you on the v8 cons.

and to "typographicalhorror", i said that the v6 "would be a bad-butt base n/a engine for a future supra", so by all means [toyota], shove that v8 in there if you want.

 

Twin Turbo mkIVs were well over $40,000. Hell I had a 96 300ZX NA, and I was surprised the learn the original MSRP was about $39K for an NA! We have it better nowadays. You can get a 350Z or RX-8 for $27K. The bottom line is the mythical $35K RWD TT Japanese supercar never existed. Hell even most 240sx's sold for over $20K.

Also, the advent of good ball-bearing turbocharger technology rendered twin-turbo systems pretty much obselete. If you ever do see another turbo Supra it will more than likely be a single or twin-scroll ball-bearing turbo. It's funny because good ball-bearing turbos pretty much started coming out in the mid-nineties right after Japanese car companies made all these TT supercars.

And like I said, we got it good right now. With oil prices going the way they're going, there may not be another monster Japanese sports car (Things like the GT-R, LF-A, and NSX excluded) ten years from now.

 

The comments about V-8s are pretty uninformed. Good luck trying to beat the LS-2 for power to weight and thermal efficiency. Maybe your calculator is rusty or something, but the last time I checked, BSFC for anything boosted was quite a bit worse than anything NA. So much for the efficiency comparisons. Also, the V-8 is inherently well balanced and the optimum design for friction/volumetric efficiency. V-8s have a lot going for them. I've also never owned one, so don't start with any foolish comments about my preferences.

The ball bearing turbo comment is amazing. I guess you don't know that ball bearings in turbos have come and gone about every 10 years since the 1930's. Ball bearings have more friction than a plain bearing, so the spool up arguments are pointless. There are two things a ball bearing turbo does better than a plain bearing turbo: 1. resist end loading 2. lighten your wallet FAST. Plain bearings do everything else at least as well, and most things better. Marketing is what makes you guys think ball bearings are better, not real world performance.

 

if you were referrring to my post, i guess you missed the point didnt you?

 

No, if I missed it, it was because you weren't clearly expressing yourself. I don't think I misread the part about more expensive, heavier and less fuel efficient. That's a highly arguable statement, it is far from fact, and the way to said it makes one believe it is fact. It just isn't true.

 

A V8 will not have the same physical size as a v6, why? Two extra cylinders. If you want to make it the same size, then you have to change the stroke in the cylinders (maybe making the block physically taller), or keep the same stroke and reduce the displacement, or increase the bore making a wider engine or decreasing the gap between the cylinder walls (making heat loss a problem). Now, a long stroke engine promotes torque, and the longer the stroke (or more 'oversquare') an engine is, the less likely it will be able to rev. Yes, V8's are excellently and inherently well balanced, but that will not change that fact.
Next, please give me some examples of cars that come base with a V6 and have a cheaper V8 model. A higher displacement V8 will always demand a higher price over a V6, i won't even get into the reasons there could possibly be. Finally a V8 would be less fuel efficient because........ well, maybe i should not have used fuel efficient, but look at it this way: Physics 101, energy is not created or destroyed, but converted from one form to antoher. Now V8 engines produce more torque (and as a result depending on the tune), more horsepower. Obviously if you have to engines with equal efficiency, the V8 would be using more chemical energy=fuel, to produce its higher output. Now if you'd like to argue you can increse the efficiency of the engine to increase the power while decrese the fuel mileage, you'd be right. But then you would be looking at higher developmental costs and more expensive technology, making for a more expensive engine.

Now unbunch your panties cause the above was never the point I was trying to get home. I just illustrated some key differences and causes in the use of engines, for a certain car (one which the topic does not even pertain to). Scince you didnt get it:
My point was that the GT-R would probably not use a twin turbo V8, because at a power level of 450-500 hp, a twin turbo V6 or a N/A V8 would be more than adequate.
Further more I see nothing of what my calculations in an earlier post has to do with the Brake specific fuel consumption.....and for your info, a V12 is a better design for friction/volumetric efficiency...how's that for uninformed?

 

I did know that, but I said *good* ball bearing technology. And regardless, my point stands. Twin-turbo systems have been rendered obsolete by modern turbocharger design, at least for relatively low power applications. In other words, for a 3l to 3.5l 6-cyl engine to make 300-400hp (like a modern turbo Supra probably would) there is no advantage at all to going twin. Except in your words, to lighten your wallet FAST. Like I said, if there's a new turbo Supra it will probably be powered by a single or twin-scroll turbo.

And good points on the V8 engine.

Maybe you could clarify a little though, I was under the impression that I6 and V12 engines were superior for balance and volumetric effeciency.

 

Agreed. a V8 in a supra just takes away from its luster. I personally dont want to see this car come back anyway. Mostly because I know that they wont live up to the Legend. It seems that all the cars that have been brought back and remade fall short from the original. Look at the MR2 for example. 130hp of ugliness. Thanks Toyota.

Im running electric fans on the one I have and it doesn't pose a problem. It's not the fans that make the cars run hot, its the front mounts. With the design of the nose and the big oil cooler people run, plus the ac condensor, and the fmic in the way, the radiator doesn't see a lot of air flow. With the stock themostat, I was seeing coolant temps in the low 200's after a dyno pull. That was with the dual electric fans, and a fluidyne radiator. I've since pulled the fluidyne (it was warped and looked horrible) put in a koyo and a 160 degree thermostat. Haven't tested it yet but we should be back on the road with her next week and on to the dyno so we'll see where she sits.

It doesn't sound like any of you have ever driven a vehicle with the 4.3liter V8... such as the SC430 or GS430..... let me tell you, that is one amazing engine it wants to revv like a Honda 4cylinder and it's a blast to put the pedal down.
I'd be all for a Supra with that engine, or even a variation of it.

Remember, the F1 cars are now going to be running V8's... and they're getting 700+ N/A horsepower out of them...
Any engine can be good, as long as you know what you're doing... and Toyota knows what they're doing.

By the way... I see no relation to the 2000 GT in that drawing... I have a 75 GT (almost no difference) I'm rebuilding and I see no resemblance.

 

No one is discrediting the abilities of the 4.3. I think everyones point is that the supra has always been based on a i-6 turbo platform. Like I said before, I cant think of any cars that have been re-introduced that have lived up to the legend. The MR2 fell WAYYY short, (i had a 91 turbo). Its not just a toyota thing. Look at the GTO. It had a great engine, but it wasnt what people wanted. The new charger has its appeal, but it falls into the same catagory. Even the 350z, which obviously was designed to bring back the Z car and to take the place of the 300zx, in my opinion didn't even come close. Many people like them, but I've driven one off and on for the last year or so and I find the interior to seem cheap and the transmission shifts feel choppy and unsure.

I could care less what engine it has in it as long as it has a good weight distribution/handling, relatively low weight, and a bucket of power.
