Why 4.7 over 5.7

[GMoney749]

My original plan was to buy the 4.7 and save some gas and some cash. But all the dealers I visited had very limited selections on the smaller engine, and as it turns out there wasn't much difference in fuel mileage so I went with the bigger motor. Plus, driving them back-to-back the 4.7 felt pretty breathless in comparison.

Definitely don't NEED the 5.7 for the way I use the truck, so I can see how some would go that route to save some cash - but I'm really glad I've got it.

I would personally buy the 5.7 or the 4.0. No point in losing horsepower unless you are going to see a SUBSTANTIAL increase in mpg.

The Toyota dealerships had some rather substantial rebates on Tundras with the 4.7L that weren't getting off the lot when we were in the market. Far more than the $1200 difference for a comparatively equipped 5.7L Tundra. Plus we really wanted a RCSB, and couldn't find a 5.7L Tundra that met our criteria. We ended up getting a great deal on a truck thats just as capable as (almost) anything the competition has to offer. Plus, its not like the 4.7L is weak.....

True, plus the timing belt on the 4.7 negates any pricing discount you got at purchase, that thing's got to be changed after a few years $$$$. I will not own a vehicle with a timing belt. A friend's late model VW just got towed to the shop with a destroyed engine because of one of those things. You can sing about how reliable the 4.7 engine is all day long, but it's still got a timing belt and that's poor engineering. I won't buy one.

Unquestionably the 5.7 for me. I didn't even consider the 4.7. Already have one of them on the wife's Sequoia. No one has mentioned that the 5.7 does not have a timing belt that needs replacing every 90K. Just one more advantage...

Timing chains will last as long as the engine does. My truck has the 5.7, for the extra money I would rather have it and not need it. Than need it and not have it. As well as better resale value.

In my area, I never saw a 5.7 with any kind of incentive. They were always 4.7 DC. They might have them now but after I got mine, I stopped looking.
I have a 5.7 because we were planning on getting an Airstream but plans change and we didn't.

If I was buying another Tundra I would probably go 5.7...but in my opinion the 5.7 is not nearly refined or as quiet as the 4.7.

With that being said, the Tundra 6 speed is not yet proven nor is the rear 10.5 axle and gearing. I also don't like that Toyota has gone to no transmission change interval as it is now a world standard fluid or something like that.

With the camshaft problem and rumble strip issue is only affected by the 5.7.

With the 4.7. Ten years of reliability is pretty good. A transmission that has been around since 100 series in 2003, refinement, quietness are all there as well.

From what I have seen is that the 4.7 moves the Tundra 4x4 pretty damn good compared to the competition. It can tow about 8500lbs, haul the same as the 5.7 and gets about the same fuel economy.

Yes it can't move a trailer like the 5.7 or blow by everything on the street...

These 4.7 vs 5.7 threads seem to get out of hand..I dont believe Lexus/Toyota has poorly engineered anything. The fact that they designed the 4.7 with a timing belt and have kept it that way has many reasons. It is quieter, is a simpler design without all the tensioners required due to chain stretch. The 5.7 valve train with its 4 chains, tensioners and dual VVT-i is a highey complex valve train. The result is an awesome powerband from the engine. It also can fail in many ways.

It seems foolish to worry about a timing belt breaking prematurely. Thats almost unheard of these days. It also seems rather foolish ,at least for me, to be worried about a maintenance issue with changing it 100,000 miles down the road. Most probably wont even keep the vehicle that long. Some owners dont require that power of the 5.7 and chose the simpler, smoother quieter, well proven 4.7.

Dont beat us up because of our wise choice !!!!!!

The Tundra is a great truck with ANY of the three engine choices !!!!!

Well said WW2, most everybody on here is nice, but the OP usually has nothing nice to say and just tries to start something. He got called out on another thread and had not responded yet. I wasn't even going to reply to this thread, but your response is right on. Besides, I don't need to make up for the size of anything with my truck.

With trucks, bigger is usally always better. Given the difference in HP, same fuel mileage, bigger transaxle, etc, its hard to justify not buying a 5.7. 4.7 owners will take a hit at trade in time. Dealers look for any excuse to knock down the trade value. A 4.7 will be harder for them to move since most people buying a truck want to tow/haul.

The 5.7 likely requires a timing chain due to the increased torque. A belt probably would not handle it.

70%+ of Tundra production is 5.7. This engine is the new standard for Toyota as it will be in the new Lexus line. I don't think you need to worry about any issues.

Your post sounds like you have to justify your choice in engine.

Does anyone think I will get $3,000.00 more for my truck on trade in / sell outright if I had a 5.7 L engine instead of my 4.7 L engine. I didn't think so. That was the difference in price when I purchased my truck. Dealers here didn't want to discount the 5.7 L engine but were very willing to deal with the 4.7 L engine.

Towing a 2,000 lb boat with my 4.7 L engine is effortless and the engine and tranny is VERY refined and quite. NO clanking when cold and NO rumble strip noise from the tranny.

Bottom line is we have gone through this how many times now and like someone else said the OP is just stirring the pot and we are the fools providing the spoon

[07DCwhiteSR5]

why do these threads pop up once a month or so? who cares. drive what u bought and let us drive what we bought.

[WW2]

well said !!!!!

Stop it with these threads already....

Go to a Ford/Chevy/Dodge forum if you want to start this crap.
