5.7 liter Tundra engine for the next 'Supra'? - Toyota Nation Forum : Toyota Car and Truck Forums

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.

<Blank stare>

Ummmm, WTF!!!???

TTercel · 02-16-2006, 06:30 PM

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)

Yeah, ummm, the Tundra is a truck....

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

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?
