Reading about the new Tundra, I kinda had a revelation.

What if a modified version of the 5.7 liter Tundra engine (I guess that engine is supposed to be a expensive option, not standard equiptment) found its way into a Toyota sports car?

Draw your own conclusions as to what it might and might not be and do, but I just thought about the possibility of doing that.

The Tundra is a front wheel drive car. You want a front wheel drive sports car? I don't want a front wheel drive sport car. The car would cost more if Toyota would be able to put it into a rearwheel drive car. I don't think Toyota made any announcement of a Super car yet though.

Ummm wow...shows how muck knowlegde you have. The tundra is RWD and is only drivin by the front wheels when you put it into 4X4 and thats 50% to the front i think i could be wrong. And if they did put the 5.7L in the Supra like it would fit, i doubt that motor can compete with the other competion with the more performance orienented(sp) engines. Toyota would be just like Dodge taking a motor from a truck and shoving it in a car...(8.0L V10 in a Viper):ugh3:

Yeah, ummm, the Tundra is a truck....:wtf:
I could maybe see them doing something like that, but with gas prices like they are, I dunno.
It would be cool if they did, Toyota needs to come out with a 500+ hp rear-drive sportscar that can say to GM, "Youve got the 'Vette? Whatever."

I read somewhere they were going to coming out with a bored out version of the 4.6L, making it a 5L, and making a special edition IS500. I think this route would be a lot more probable than putting the 5.7L into a car.

I am pretty sure, if they did use the 5.7 in a car it wouldnt have any problems competing...supposed to have close to 400hp in Tundra form. Also the Viper's V10 was created for the Viper....later added to the Ram as a special edition.

The most logical "supra" replacement or comeback car for the sports car world would be "de-luxed" versions of the IS. The 250 for the entry level and the 350 on the high performance end. Would be very simple and cost effective for Toyota to go this route. Nothing would be changed drivetrain wise, except sourcing a 6-speed manual for the 350 engine. Also, these engines would do nothing to hurt Toyota's image of being "green" as these engines get excellent gas mileage.

And this isnt meant to start a "the Supra Lives!!!" thread, but working for Toyota, this is seems to be the way it will happen........IF it does.

yah, a 5.7 would really put it more in the corvette/viper class. Not sure that's their plan....at least not for toyota (maybe for lexus)

a IS based coupe would be the ticket. Not just since the development work would be minimal, but since it would be in the right price range ($28-36K) to compete against its natural rivals (Nissan Z & Mazda RX8). Going much past that wouldn't make too much sense at this stage of the game.

Toyota wouldn't do that. Besides the 5.7L is a truck engine, maximized torque for towing and mountain climbing. None of the Toy/Lex truck based SUV's and trucks share engine with their cars. Looking at CURRENT engine choices, the following are best candidates for various supra/sports car trims:
3.0L V6 245hp (as in gs300)
3.5L V6 306hp (as in is350)
4.6L V8 380hp (as in ls460)

Yes but the 4.7 that was put into the Tundra was based off of the old 4.0 that Lexus has had in teh LS400. I said based off of not exactly the same. Also if you look at the old 3VZ from the late 80's to early 90's they put it in both the Camry and the Trucks. Granted there were different cylinder heads for both of them but they were still the same engine code. Just because an engine is built for a truck or car does not mean it cant be used as a platform for another engine to go in the opposite type vehicle. NAything is possible. everyone said the 2GR or whatever it is in the IS was a RWD designed engine and wouldnt go in a FWD car and now they are using it in everything under the sun. Same as Nissan did with the VQ engine line.

I dont think they would base it off the IS. The IS would be too big for the Supra. I also dont think they would put the 5.7 in the Supra b/c I think they would go after the Skyline crowd not the viper crowd. Maybe a Lexus to go after the vett and viper.

This is how rumours get started. Next time how about starting your thread Title as "WHat iF? or I'd like to see". Maybe I'll start a new thread titled 85 MPG 280hp $10,000 factory spec Corolla XRS. ANd then in the body of the thread I'll say "Wouldn't that be neat?".

During the prototype days the Viper had a 8.0L V10, this engine was suppose to debut for the Dodge Ram but never made it. If all of you remember the Dodge Ram 6X6:naughty: This is the only time it got that motor.

Um, no. The 5.7L has a torque peak that's tuned and suitable for towing, not for acceleration throughout the rev range. It depends on the bore and stroke of the motor as well. If it's a big bore, short stroke motor, then Toyota could slap on some dual VVT-i cylinder heads with D-4S and create a 500hp monster at 6500rpm. If it's a big bore, long stroke motor, then it's not really suitable for anything but truck use. I don't wanna get into rod ratios and things like that. Short stroke engines just rev easier, and faster too.

The 2UZ was a mistake from the beginning, because Toyota increased the bore of the 1UZ, and did nothing to the stroke. Stroke is important for low-end torque and engine response. That's why many people complain that the 2UZ starts off lazy, while the 1GR feels like a better engine (big bore, long stroke), even though it's a V6. Toyota tuned the 2UZ for a truck application

The best bet for a 'Supra'-like performer will be the rumored IS500 coupe. Using a bored out version of the upcoming 4.6L, and weighing in with a displacement of 5.0L and over 450hp. Dual VVT-i, and D-4S will top the list for engine enhancements.

TTercel: I guess I didn't read the whole thing about the Tundra. But I have a question, I really don't undestand the 4wd thingy. Why is the truck using the two front wheels to move instead of all wheels when in 4x4 mode? Why would a truck switch from RWD to a FWD in 4x4 mode?

According to AutoSpies.com and CruiseIRL.com, the Toyota Supra already exists; at least in prototype form. There was a spread in the December 2005 issue of Japanese car magazine 'Best Car' supposidly based on a 'secret' document; rather good photography for something on the hush. Either link below will take you there. The base engine is a 330-350hp 3.5L V6, and a 430-450hp 5L V8. Sorry, nothing there about a 5.7L Tundra-based engine....

In the second link... it shows the 2GR-FSE and 2UR-FSE. Apparently Toyota is moving to xR series engines. UR = UZ, GR = MZ, 5VZ.

lol..yes...how things works will help.



dude...okay lets get down to the gist of it....

there are two types of suv's out there ( to make it simple..2... and i say suv generically though the tundra is a certified truck-- it has a SUV counterpart off the tundra--the sequoia)


2


one is the truck based SUV

the other is a car based SUV-(wannabe)



1... in a truck/suv that has AWD .. most that are based on truck platforms has an even distribution of power to all four wheels or even biased for the rear to get more power
2....in the car based SUV or even a car with AWD... the main drive wheels are the front. It is when the rear is needed.. ie the front wheels are slipping is when power the sent to the rear wheels. this is the case for most car based awd systems though there may be exceptions here too.



Now in the truck... why would power be sent to the front? when in 4x4?... not the case.
It's that the power is already there but possibly the rear is slipping and now the front is pulling the truck forward.

then there are all the combinations and types of 4x4 systems....

I am still trying to figure out why the IS would be too big(?) for the Supra to share platforms?!?! It is the perfect size. The mkiv's length was almost 178 in....the current IS is 180in. The wheelbase of the IS is about 7" longer at 107.5". This means you make it 175" in overall length and we will have some nice short overhangs. If you use the 350Z as reference its wheelbase is 104" and overall length is 170" so the size would be just right, and make it a little better for big guys like myself (6'3"/240lbs).

Wow, sorry but I'm speechless. No automaker is stupid enough to market a pickup truck as FWD only. What's the point of it being a truck then? :confused:

Lol, even honda didn't market their truck as a FWD, even though its a FWD setup using AWD components.

Let me explain FWD, AWD, 4WD, RWD:

FWD: (Front Wheel Drive) is a setup used by most car manufactures nowadays in minivans, cars, medium and compact sized SUVs. Most popular ways of mounting an engine in a FWD car is sideways. That means the pulleys are facing the strut towers. But I've seen some FWD vehicles like some Acuras that have the pulleys facing towards the front. FWD vehicles yous a transaxle. A transmission that poweres the wheel directly with an internal differential, instead of like a conventional transmission that sends power through the driveshaft then into a differential. You do get more power out of this setup, but almost all driver enthusiast will tell you, RWD is their choice.

AWD: (All Wheel Drive) is a feature that sends torque to all the wheels. All wheel drive has two setups im familiar with. One, is using a FWD setup with a driveshaft to the rear wheels, and two is a RWD setup with either a transfer case thats bolted from the back of the transmission that sens power via driveshaft to a front differential, or a transmission that has a differential mounted inside the front of the transmission itself, wich has two CV axles comming out of the sides of it. The last setup is very uncommon and complex. As my opinion, I see no real benefiet for AWD, as its heavier wich causes more wear and tear, and makes fuel economy and acceleration suffer. But the benefiet in AWD is you wont spin tires when you accelerate on a wet surface. Offroad is a different story.

4WD: (4wheel Drive) is my favorite feature in pickups and SUVs. Its a RWD setup with a 2speed differential that gives out a locked 50/50 power output to the front and rear wheels. 4WD should not be used unless needed offroad.

RWD: (Rear Wheel Drive) my definite favorite when I dont need to go offroad. RWD sends power from a transmission through a driveshaft to the rear differential. Some midmounted engines use the AWD setup, but alil differently. Still, RWD is fun to drive, if you know what your doing. RWD is dangerous in snow, and if you take a corner and punch the gas, your likey to break traction and fishtail. The worst thing you can expect from fishtailing is loss of control and possibly a 360 spin or a roll over.

Anyway, my 2cents. Feel free to correct me. Now that we got the drive train setups out of the way. Back to Supra 5.7L

On the 3UZ though (the 4.3L V8), torque was given more priority. See dyno charts from Lexus GS350 and GS430 (JDM models). Interesting how the V6 was tuned for more HP. However, the V8 produces considerably more HP at lower RPM's (naturally). V8 model costs 'bout $10K more.

The torque curve on the 3UZ is too peaky, which is why it can make more horsepower earlier (along with displacement advantage), but levels off later. Where the 3UZ falls flat on its face, the 2GR keeps going strong. This is what Toyota aims to fix with the new 4.6L (1UR?). The bore was also increased from the 1UZ to create the 3UZ. The 3UZ would benefit from cams with more valve lift though. This would help flatten its torque curve, and increase overall horsepower. The 1UZ and 3UZ share the same horsepower/torque specifications. Toyota increased the displacement to make the engine smoother and more docile.

The 3UZ would definitely feel better in the GS though, since it's a heavier car.
