6.0 taco now!

I guess we will see, how did you break yours? Leave the locker on going around a round a bout lol?

 

What’s 4lo ratio x torque of a 3.4 n/a? Pretty sure it’s a lot more than a stock 5.3 at a generous 300ft lbs

 

Bro you obviously cant be reasoned with... Its your $$. You would have to be dense to even think for a second that rear end will hold up..

Carry on....

 

You just have never said why? Or what fails and why.

 

Wonder if jimmy johnny would chime in on the subject with his 5.3 Tacoma

 

He's not going to blow up an open rear diff on a stock 5.3. You're just being a fear monger lol.

 

Were those factory gears or 4.88-5.29s?

Was that with those 39" reds attached?

 

4.88s and 37 SSRs and 5.29s on the 37 SSRs and 39" Chinesium tires. both rears gear sets, never the HiPinion front.
No breaks on the Reds with the D60/14B axles with 5.38s

 

Let the experiment begin. LOL

 

4:10s on 285s.......... your trucks and this one are in way different ball parks lol now I could see an issue if I mounted up my 33x10.5w slicks on it but math works wonders man. especially with no multipliers like 4lo

 

4 low has nothing to do with it...

 

The factory 4.10s are pretty stout. 4.88s and 5.29s get into small pinion territory and the increased number of teeth on the ring gear means that they are less stout as well. I think OP is going to be just fine.

4 low does matter, it's multiplying the engine torque applied to the ring and pinion when the tires are bound up. I ran 35s on 3.91s for a while and then regeared to 5.29s. I never broke anything on 3.91s but with 5.29s I've kissed CVs and chromoly axles goodbye.

 

First off, you all are using the wrong comparisons for the application here. A 22re will break 1 tons if you bound them up just right. Having power doesn't mean you're going to automatically break something.

If OP was 4x4 with 37s+ I'd say he might want to step up the rear axle, but he's 2wd on open diff. He's not rock crawling. Axles snap and R&P shred because tires are bound up and there is load coming from the drive shaft. An open rear diff with 33s isn't going to break anything with only 300 hp. Like I said earlier, it's just fear mongering.

 

Unfortunately it doesn't work that way and you should probably have a plan for an axle swap. I've only have a 2UZ and have a back up plan for the rear axle, still need to figure out what to do if I pop the front.

Side note, I wish I would have gone the 5.3 route instead of the 4.7.

 

No you're wrong. Have you ever used a torque multiplier on a wrench? You can literally feel in your hands the same thing low range does for a truck.

 

A combustion motor is not capable of going from 0-Max torque value in 0.01 sec, your wrench can. This isn't a mathematical equation under ideal conditions, this is real world where you have outside factors creating significant influence.

A 3.4L motor in 4Lo cannot apply the same potential torque value to the rear axle that a V8 can in 2wd*, because of torque losses in the transmission and transfer case and the split of toque being divided between the front and rear axle by the now locked transfer case. Even if you pull your front drive shaft it is still not the same because of the additional power losses in the transfer case. Another important factor is weight transfer, the OP and I can create massive weight transfers to the rear axle in a split second with nearly 100hp more than a 3.4L.

Edit to add, axle planning is more important for me than the OP because I'm currently shopping for 35s, and plan to be stupid occasionally.

*With significant modification it could be possible, but who's going to throw nitrous at 3.4L and turbo set up weighs more than the V8.

 

The wrench was just an example. I figured some who tries to sound as smart as you do might have figured that out.

The 3.4L with a multiplier (low range) puts out more torque than a 5.3L without a multiplier. The axle itself doesn't know or care if the there's 2wd or 4wd, high or low range, it has a max load capacity in foot pounds. As long as the load is under that rating the axle is fine. The 5.3 is not going to destroy the rear axle in these trucks if driven normally. The axles out of the half tons are basically the same size as the tacoma rear axle.

You're just spouting a bunch of shit trying to sound smart and you're missing the point. A 5.3L at max torque value without any torque multiplier (low range) is still within the threshold for the tacoma rear axle. You think you're right, but you're not.

 

You're going to love it. I was having such a hard time keeping my foot out of the throttle when driving around the other day, still have to get that last O2 to read "ready" so I can pass emissions then I can ham it up. I'm a little jealous of your 5.3 because of all the bolt on option your have.

Thanks for the insult.
You're welcome to keep staring at a micro viewpoint, ignoring everything else, and I'm going to keep looking at the whole system and preparing for those moments where I'm not acting like a responsible behind the wheel of a V8 Taco. In the mean time ride safe and I'm going to go do some donuts, because who puts a V8 in one of these trucks and doesn't enjoy a good donut or smokey burn out.

 

This proves my point. You feel it's necessary and in turn are trying to prove it's necessary, when infact it isn't necessary. If you wanna get stupid, then by all means upgrade your shit. I definitely approve of that, but don't sit here and mislead people to believe that a 5.3L will destroy an otherwise stock Tacoma.

 

I agree 100 percent! I don’t even know where or how this topic got started but In my mind and and math it’s not an issue. Like I said earlier if I put these tires on yeah I might have an issue but more than likely it will throw a ujoint before the rear end.
