What models are available with V8

[07V8]

Sorry, but the V6 is not as reliable, durable, or smooth as the V8 period. There is no substitute for the over engineering on the V8. Iron block, forged internals, iridium pkugs, lack of an EGR system etc etc. The V8 was designed for the no-compromise Land Cruiser. The V6 is not even in the same league.

You can argue minimal paper differences between the two. The fact is the driving experience is completely different.

End. Of. Story.

I'm pretty sure these motors do not have forged internals. Otherwise, those early S/C kits wouldn't have put so many rods through the blocks. :shrug:

Pretty much boils it all down....

If you want a V8 your going to get a V8...better torque, more sound ! more gas! and quite frankly, I got one for all those reasons and the fact that it is a quickly fading part of American car culture...

HELL there is even an F-150 with a four cylinder.. the technology of new turbos and direct fuel injection is fascinating and produces huge power, the competition is not between just companies but technologies (Gas, Diesel, Electric etc.) so it is only a matter of years before what we know of automobiles is totally different, it already is


Also a good point to consider is the recession of the late 00's, really sort of drives up the used car market...

Only the American 2UZ in the tundra and sequoia had cast rods. Japanese 2UZ in LC and 4R never had rod issues.

Power and torque are one thing. You can blow a small displacement engine and get both, we know that. Long term reliability and durability are another. I guarantee the 2UZ's will still be around and driving like new long after small displacement, sky-high revving, aluminum blocked blown engines get some miles on them.

I've looked into this and found no solid evidence to support that claim one way or the other. The reality is that they are "forged" like other "forged" connecting rod; by taking metal powder and pressure forming it into a rod. This is common practice with the majority of all manufactuers, as opposed to pouring them. The main issue with the 2UZ and all the other V8's & V6's is that Toyota makes these rods very thin to save weight and reciprocating mass; great for the NA motor, not so great when you're trying to bump up the compression and it detonates.

haha, gotta love flashbacks on Internet forums. :tea:

Blackworks, I like you man. You often have good things to add to threads, and I have seen you help people out.



Really? Where did you get that from? Toyota's chief engineer? Last I checked, they still make the 5.7 which is a HUGE gas hog, the 4.6 ain't that efficient either. If Toyota really was going towards efficiency, they'd be bringing their D4D diesels here, not downsizing their truck engines by 0.1 liters.

The 4.7 was killed because customers weren't buying it. It was mediocre. Period.



My neighbor just bought a GX460. He got a lightly equipped one and it was $53k. So, no, the 5th gen V8 is not the GX460. Not by 10 grand.



You conveniently ignore the higher up front purchase cost of a V8.



There you go, you made my point for me. Toyota killed the 4.7 because it was only "just a bit better" that most educated buyers passed on it.



Again, where do you get this from? I am running 34.1 inch tires and ~500 lbs of armor in my V6 with no noticeable loss of power or needing to regear. Hell, my mpg is even largely unchanged. Not sure where you get some of your data points from.



Awesome, good for you. Want a cookie?

Good god you're an idiot. They killed the 4.7 because of the recession, gas prices at the time and competing with the other V8 trucks/SUV's. There is a stupid misperception that the V6 is almost as good as the V8, it aint'. Period

They killed the 4.7 because of this recession you speak of, but kept making all their other V8s, including the 4.6 and 5.7???????? hmm yeah, that makes a lot of sense.

You are a complete knuckle head. I revoke my offer of a cookie. No cookie for you! Now down!

Yet as I mentioned above, the 2UZ-FE was used for quite some time in other products because it was such a strong engine for Toyota. For such a "paltry" engine, there sure are a ton more Tundras with 2UZ-FE's in them than 1GR-FE's as I pointed out a couple posts above... So you're logic that consumers "knew better" is a bit flawed there. Not to mention the 5th Gen's opening gambit was offering the truly pathetic 2TR-FE Inline 4cyl engine in 2010 because Toyota was specifically trying to revive sales with a more "fuel saver" image of the 4Runner, one of the main reasons the 2UZ-FE was dropped, again as I had pointed out in my post above.

It's about context and looking at the whole picture, hell I'm sure if we wanted to [MENTION=66316]1engineer[/MENTION] has reams of sales data on the 4Runner. He enjoys graphing all that junk.

One thing I've noticed on the V8 over the V6 is it is a very low revving engine, extremely quiet. Up hills, coasting at 80mph, always below 2000rpm. Both my third Gen V6 could not do that, don't know about new 4th / 5th Gen V6. Gas milage is similar. The timing belt change is a very amateur mechanic job so that shouldn't scare anyone. I would test drive both and see what you like. What you need to check on the V8 is the 4wd hi / low actuator. These lock up when not cycled every now and then.

80mph and less than 2000rpm? That's news to me. I do that every day and I'm around 22-2300rpm

His point is it doesn't have to downshift and run at stupid high RPMs to maintain speed on grades.

 

[good2go]

I love the power/torque of my 2003 SR5 V8 2WD - specially with the Gibson exhaust setup. It is more than plenty for short/long trips, unloaded/loaded, hills and mountain roads - with low running RPMs unless I rev'd it. I do not care about MPG, otherwise I would have purchased a Prius - which is never!

Even though the V8 was only rated 235 HP on paper (while V-6 @ 245 HP - go figure), my buttdyno feels much more than that. It still kicks even with the lift, rack, add-on mods, and big tires. I am very happy with my purchase, that is all matters - it's a personal decision. Never like over analyzing things: "Analysis-Paralysis."

Maybe 2100 , I'll have to look next time. I honestly try and keep it at 75. But that brings up another point which I actually didn't like at first but I've come to - and that's at any speed really when u let go of the gas the truck is geared so that it it's like you've applied the brakes (besides the box like aerodynamics) and starts to slow significantly, one more quirk to consider on the v8 (mines a 2003 built nov2002 v8)

Yes sir, which was very noticeable in the 3rd Gen V6, as well as loud since I did the silencer delete.
