Ok, how about the fact that the block on the v8 is forged iron vs the cast aluminum that is found on the v6. There is nor exhausr gas return system on the v8 which reduces carbon buildup in the engine. Furthermore, the internals of the engine are just made of better components. The v8 was originally designed for the land cruiser in 98. Trust me, toyota would not skimp on any part going in that engine because of the price, reputation and all around better car than the 4runner. The v6 was designed for the 4runner which unfortunately is not even in the same league as the land cruiser.....yes I'm very partial to the land cruiser.

Where do you find the V8s block is forged? I have not read of any carbon build up problem with any V6 engines Toyota or any other V6. You post the V8s are built with the better internals parts of the engine. Just what parts are better and how are they better?
There are billions of of engines using alloy blocks with cast iron bore liners and they have stood the test of time.
What give you any idea Toyota is skimping on anything with the 4Runner
Myself I don't care about what the land cruiser has or what class it's in. This being the 4Runner forum unless I have missed something.:bash:
And if your as you posted (very partial to the land cruiser.) Why not find their forum.

I don't understand what you don't get....the v8 is a better made engine period. Trying to find any technical documents on any of these engines is next to impossible. Furthermore, I never said the v6 was bad, I simply said that the v8 is better in all respects except mpg.riverider said:I agree V8s have more power they are Designed with heavy hauling and towing as the reason many buy them in Trucks and Autos, but someone making the statement that Toyota uses better components in their V8s then in their V6s is not factual or truthful.
I own a Truck with a V8 have owned many Autos with V8s. I own a 4wd truck with a V8 now. When I decided to get rid of the Sorento a very good V6 engine with 4wd, I did not need another 4wd or a V8.
What I really needed and would get the most bang for the buck was a rear wheel drive 2wd V6, that did not beat me to death over every small rut in our Cities really bad streets and roads.
The 4Runner 2wd V6 meets and exceeds all my needs and demands.

What your posting is you don't know really anything about what is really in a V8 or V6 engine as far better parts.
Being more powerful with the extra weight does not make the V8 better, if someone does not need the extra power it's just dead weight to haul along with you every time you drive.

IMHO both the V6 and V8 engines have their pros and cons depending on their use. The V6 is not a piece of crap nor is the V8 a huge gas hog.
Back in 2004 when I purchased my V8 4Runner, there were important differences (to me) between the two when it came to how they could fit my needs.
The V6:
- 13% less Torque than the V8
- 5000 lb Non Weight Distributing Hitch
- No transmission cooler
- 4 speed Transmission
- EPA Fuel Economy of 17/21
The V8:
- 13% more Torque than the V6
- 7000lb Weight Distributing Hitch
- Transmission Cooler Standard
- 5 speed transmission
- EPA Fuel Economy of 15/19
Since the primary purpose for my 4Runner would be towing, the V8 simply met my needs better than the V6 did right out of the showroom door.
Had I purchased a V6 I would have had to upgrade the hitch and add a transmission cooler suitable to support towing.
Even if I did that I would have faced possible legal issues had I gotten into an accident towing with a V6 and it was found out I was over the rated towing capacity of the V6.
Having been towing with my V8 for a few years now I have to wonder how well the V6 could have pulled my enclosed trailer weighing around 5,200-5,400 lbs.
Pulling that brick most likely would have forced the V6 to work harder.
Knowing the hit I take in MPG with the V8 when towing, I cannot see the V6 towing the same load could possibly do any better MPG wise and could even be worse.
Have to wonder how many V6 owners tow trailers weighing 5,000 to 7,000 lbs? Would like to meet some of them and talk shop as far as towing goes.
I suspect there are not too many out there.

My reason for choosing a V6 instead of the V8 was not based on power or mileage at all. I based my choice on the fact that I had the option to run my truck in 2wd or awd. You do not have that option with the V8 as it runs in awd. (Canada anyways) I figure there would be more wear and tear on components/tires in the future with the V8. Mind you I haven't heard any one complain about this.
I like the current V6 engine. It has lots of power for my needs. I can keep up or exceed my my bro's supercharged 3gen and still get better gas mileage. Thats good enough for me.

I think you've mis-read my post. "V6 is no where close to not being smooth". Double negative. i apologize if i've made it confusing
V6 is for mall cruisers
V8 is for workhorses.
I've read stories on this site of folks towing with V6s and actually getting WORSE mileage than I do with my V8 while towing. I usually tow a 4,800lb car trailer at 75-80mph and get 13.2mpg doing it. I've read stories of folks in V6s towing trailers and getting 9-11mpg because they are working much harder to do the same job.
Fact of the matter is, the V6 feels 'smooth' because of excellent engine mounts that isolate the vibration from the frame/chassis of the vehicle. It's well known and proven that V8 engines are typically much better balanced than V6 engines. The best balanced/smoothest engines in the world are straight-6 engines, although aside from BMW, you don't see them around very often.
Stop beating the dead horse. Get what you want or what will suit your needs. Just don't try hitching up an 8,800lb trailer behind your V6... My V8 had no trouble pulling it, though.

It looks like your the one who just can't quit harping v8s' and just beating a dead horse gas milage of a thread to death.
I think everyone now understands you area a great lover of the tried and true old V8 engine. And I think we all now know your getting super gas mileage hauling that 4.8K load at 75/80 mph.
Wonderful, I am really happy for you.

Dont be disappointed because you opted for the V6
riverider said:
Actually, considering I don't get much worse than some people get in-town, I am pretty happy with the mileage.
I got 18.8mpg (hand calculated) on my last tank of mixed city/highway driving. For a vehicle with this capability, I cannot complain whatsoever.
As I said -- each has is pluses and minuses... GET WHAT YOU NEED/LIKE/WANT. The V8 is superior in every way except initial purchase price and gas mileage. Period. End of story.

Why dont you go drive your 2wd 4runner around town or take it to the mall. IMHO a 2wd SUV is an oxymoron. Should have just gotten a ricer and put a fat 4" exhaust on it. Just about as useful as a 2wd 4runner

V8>V6

My brother has a V8 4Runner that he picked up two weeks ago. I have a V6 4Runner that is otherwise identical to his. I guess 4Runners run in the family!
The funny thing is that I've had the chance to drive his a couple of times recently and the V8 engine isn't any smoother than the V6 in my 4Runner. Yes, it is very smooth, but so is my V6. I'm not sure why so many V8 owners think that the V6 is not a smooth engine. It's about as smooth as possible by modern standards. It idles incredibly smoothly and it pulls through the rev range very smooth.
And for the guy who wondered why the V6 has a timing chain and the V8 has a belt, its because a belt is inherently quieter than a chain. Since the V8 engine is shared in the Lexus, it makes sense for them to make it as quiet as possible by using a belt. The chain is definitely better in terms of longevity and durability, but the belt is more quiet. Simple as that!

Back when you purchased your 4Runner, the V6 engine actually made a little more HP than the V8 engine. Yes, it's true that the V8 made more torque, but when it comes to HP, the V6 had a small advantage.
The other difference was that still holds true today is that the V6 has a 2wd mode, which is important to some people. That's one of the main reason I chose the V6 for myself. I wanted to be able to run 2wd instead of full time 4wd. Since I live in the snowbelt, I generally run full time 4wd in throughout the winter months, but then switch back to full time 2wd for the rest of the year.
