4.6L vs. 4.7L V8

[G.I.G.]

GX | Detailed Specifications

Aluminum block like its 5.7 sister.

I stand corrected. Seems as though there have been some misinformation published since the launch of the 4.6L last year.

Re: your points above - I will probably never own a car long enough to experience those issues. I will; however, have a very hard time parting with my 4R when I do. I remember reading an editorial written by a Car&Driver big wig. It was an article about his favorite car. He drove rare exotics, old muscle cars - basically everything we could only dream of. However, he said his favorite car was his personal 4Runner. He slept in it, took it on many trips, seen much of the country in it etc etc. Its this kind of "relationship" that makes an owner love their car. Its not a car that can rip your head off with speed or some flashy rare exotic - its the one you can do almost everything in and the one that has always been there for you. Off topic I know but I feel the same way with my 4R.

I agree. I plan on driving my current 4Runner into the ground. I too have slept in my 4Runner, gone camping with it, and done 4-wheeling in parts of Colorado that most people will never see. I wouldn't venture out to some of these places without knowing that my 4Runner was 100% reliable, especially considering some of these trips have been solo.

Interesting info. One of the things that makes the 4R V8 so great is the engine internals. Since the truck was made in Japan, the connecting rods and crank were stronger than the V8's made in the states.

Do you know whether this 5th gen is made in Japan?

I may consider the new V8 when/if they put it in the new 5th gen, especially if they address a lot of other issues with the 4th gen such as the brakes and the rust in the underbody.

I've had both and I can tell you the 4.6 is the evolution of the 4.7 (and I loved my 4.7). The 4.6 has noticeably more power, more torque, better mileage, smoother and is lighter (all aluminum). It also produces these gains at lower RPM. It is mated with the 6 speed trans and idles at lower RPM. The 4.6 is an amazing motor!

Let me guess… by that time your envy of having V8 will be gone and you will be ready for upgrade from V6..?

:

Who wouldn't want something better than the current V8 or current V6?

If I wanted the current V8, I would have bought it, or, I could stay trade for it. Not interested.

Toyota Tundra Truck - 2011 Performance and Specifications

Aluminum block like its 5.7 sister. 4.7 and 4.6/5.7 are completely different. 4.6 is a smaller derivation of the 5.7 which was newly design for the 2nd gen Tundra.

I read the same article and started a thread on it here. I'm not sure if he was ever clear whether he had a V6 or V8.

4.7 minus 4.6 = .1 Not a very big difference, right?

The folks who bought a 4.7 V8 did so when that was the only motor available.

Most of us know that the 4.6 is the evolution of the 4.7.

I'll bet that most of the 4.7 owners absolutely enjoy their engine knowing full well that the 4.6 is 'what's in now'.

Almost every time I get in 4.7 4Runner, I enjoy driving it... and the engine.

That doesn't mean that anyone is putting a gun to my head to 'upgrade' to a 4.6.

Why?

Because it doesn't exist in a 4Runner!

For the time being, the 4.7 is a great engine and fun to drive. :

Hey Koz,

Not to start a war with others on the thread but wondering what you are experiencing for MPG on your new GX? I know it's probably not broke in yet and will get better. I just know the EPA ratings for my 4Runner were not even close and I'm sure my "new to me GX" will not be either. I have a fat right foot. Thank god my commute is about 3 times a week and five miles round trip. I'm honestly just wondering what your MPG is.

They used a belt because they wanted uber-quiet operation which the 4.7 delivers on.

I feel if Toyota wanted to they could have tuned more from the 4.7. Its an Iron block - they could have put a forced induction system on it without redesigning a new engine. However, I believe that the 5.7 is just a bored out 4.6 bock (except they went big to small) this time. IIRC the 4.6 and 5.7 have the exact same OD's. (Outer dimensions)

And I thought I trolled....

I believe the 5.7 has an increased stroke. Therefore piston size is the same. The 4.7 / 4.6 and 5.7 have the same bore.

IIRC, stroker motors make lots o'torque - to the tune of 400 lb/ft in the 5.7

Wich brings up another interesting question - Toyota did a lot of work in developing the 4.6 - as it develops more tq with slightly less stroke than the 4.7. Cam profiling can play a role as well.

I think you need to read the article. It'll explain a lot for you.

I read the article. Sorry, i don't believe in them.

If there's no point, why are you posting? Duh.

Do yourself a favor and read all the posts where people were enlightened by how the old 4.7L V8 has evolved into a better machine, the 4.6L V8.

Since at this point, 4.6 V8 in the 4Runner is a wishful thinking and probably will be for a long time, the current 4.7 tops the list…

You need thicker skin.

You're like the pot calling the kettle black.

You obviously cannot give an educated or objective opinion on these two vehicles when you imply the T4R is better off road, when you probably have never ever driven a GX. Then to imply the GX has a rollover issue is totally ridiculous. The FACT is the premium GX is actually shorter than the TE T4R (the base GX is the same height as the T4R). If you don't know what you are talking about, do yourself a favor and don't let everyone know it.

Koz

And then I squashed all your "points."

Somehow I missed your post, anyway, I have not taken a highway trip yet so I can only give you my city mileage. I get between 13 and 14 mpg. This is strictly city, no highway at all. I always get the worst mileage possible because of the problem I have with my right foot. It seems to always get pinned to the floor. I'm a very aggressive driver to say the least. My wife says I would race an old lady walking across the street. lol
