4.6 1URFE motor and transmission swap

[084RUNNAH]

Having had some wheel time behind the 4.7 and the newer 4.6... I would vote for the 4.6, more powerful 305hp and better MPG and it feels better and its a super quiet/smooth motor.

Ride/drive a newer GX460 then jump in your T4R, to really feel the envy.
Feels like something is wrong with the T4R...try it if you don't believe me.

Still, for what I do and my funding levels...I love my T4R, would not trade it for...well that's all objective.

Looking at your sig, I don't see any URD MAF Calibrator in there, that thing really wakes up the other intake/exhaust mods you or others may have done.

Here is the plug-n-play.

Is a wired one for less money.

Cheap FUN.
May use more gas...speak to the FOOT.
I was up to 15.7 mpg this summer, driving like an old fart.

Yeah, I have the URD MAF sensor calibrator which I spliced in a few years back.

I still have to take a 4.6 out for a test drive. I was going to go today until my wife delayed me. The best part is she supports the decision for an engine swap :banana:

man i really vote you at least regear your truck to 4.56s first and see how you like it. then maybe add a supercharger, much easier and cheaper.

after doing a few swaps ive learned its not the big things that are the problem or most expensive, its always the little parts and changes that nickel and dime you to death and take the most time, be prepared to be down at least a month and add 2500 at least to your estimated cost of the swap. if youre dead set on doing a v8 swap into your runner more power to ya i guess.

Really interesting video I found today.

10 months of intense personal research + $12,000 is what it took to swap an 03 Sequoia 2UZ into a 3rd gen for this guy. He made it CARB legal though.

If you bought a 4th gen with a bad motor for a couple thousand, and were buddies with a guy that owned a legit shop that has messed with Toyota's before, then I could see it happening. Or if your 4th gen was just a trail rig that gets trailered to wheel spots you could get away with a cheap swap with a CEL on or something.

Other than that I think it would be a lot easier to just throw in a supercharger or trade in for a Tundra or LC. 1/2 the price and 1/10 the time easier.

My only issue is doing a supercharger and re-gear and in the end regret it all and wasting all that money. Wish someone was nearby that I could check it out and go out for a ride with. I will

I already have all the equipment to do the job. I am an auto mechanic so I have all bases covered. I've done straight forward swaps before other than my mk3 supra which I converted to a 2JZGTE 6 speed. Also my previous car which was a Mazda MX-6 which I swapped motor to a KLZE motor which was not too bad. I have not done a 4Runner yet but it would be an awesome project to take on as I would like overall more power and efficiency on long road trips.

Also, I would have an extremely low mileage motor, headers, not sure about exhaust and maybe transmission for sale which would help with the reduce the cost of the swap.

I vote for the re-gear, you won't be losing anything and will be happy with the lower gears with your stock motor or the motor you want to swap in. Also as stated no motor swap is going to help your budget and the 4.0 is probably one of the best motors Toyota has ever made. If you really want more power sorry to say it but the LS is about the easiest best option.

I'm going to post what could be considered heresy in Toyota land, if you want a V8, do a LS swap. They are simple, cheap, abundant, reliable, & make a lot of power. A 5.3 can make 400HP relatively easily. A 6.0 will get there even easier. Find a LQ9 and have at it. Sometimes, one cam is better than 4....

 

[gm350reratliff]

I do want to see this swap happen but.....


In reality, I think an LS swap is the way to go and it’s probably what I’d do if I were going to swap. There’s just about everything available for the LS and that goes for tuning and communicating with the rest of the vehicle. I do like the 1GR in the 4th gen and do consider it one of the best made but there’s really no tuning available and not much in the aftermarket world either.

OP- if you’re dead set on that 4.6 swap, don’t let us sway you, make it happen and share the pics with us.

Since Drunner97 got me thinking about weight, I decided to go take my truck on the scale to have an idea how much my beast weights. I was quite surprised. With only me and a half tank of gas, my truck weighed a whopping 5700lbs or roughly 2600kg. I thru in my sliders, and winch in the trunk since I'll install them in the spring.

That is almost the weight of a base model Sequoia with a 5.7. That is not even including a rear bumper with swing out, an actual full spare tire, drawer system and an audio system lol.

So back to the drawing board. Will the 1GRFE be up to task with a supercharger and re-gear? I've read somewhere stating that a 5.7 can physically fit in the engine bay or maybe that was on a Tacoma which is essentially the same as the 4Runner. Hmm

I also have a daily driver which is a Volkswagen Passat which is temporary until I figure out what to do with the 4Runner. Fuel does add up as I drive 26km / 16miles one way and I granny it which takes the fun away. My worst mileage was 15 mpg if I push it once in a while. Truck also has low mileage - 62000kms / 39000 miles.

I can't believe that your truck is 1000lbs heavier than my 06' Limited. Mine weighed in at 4700lbs with me in it. I think I had about a half a tank, it was weighed at the dump though (who knows how accurate the scale was).

I'm interested in your swap. If you ever need a hand, I'm about an hr south of you by NF. I would consider a OV tune before you go down the road of a swap though. Their tune on the 4.0L 2nd gen Tacoma looks promising.

Did you ever start the UR swap?

Or buy a v8 runner and swap stuff over?

I hate to revive an old thread but curious at what the original poster found out.

I am working on this engine swap into my 2015 tacoma while I drive around in a 2005 v8 4runner. I wont be able to handle going back to the 4.0 even supercharged. it would have to produce 400+ to be justified and that's just too much to ask of it.

One other thing I was hoping to figure out is the complexity of installing the 6 speed auto into the 2uz v8 chassis. This would allow much lower gearing and a lower first gear if you so pleased.

Gearing at the differential side is a lot easier. First gear is pretty short on mine with 4.88's and 35s.

your only thinking of it one way. you could run 5.29s and still have a highway rpm with the 6 speed.

Yeah but what I'm saying is that you don't need a lower first gear.

I'm all for more gears, but it's a lot easier, if you wanted a lower ratio, to do it at the diff side.

its not just about the lower ratio though...... maybe that's what I am not explaining good enough. By lowering first gear, found tall by many when lifted, and splitting the rest of the gears as well as adding a last gear. you get a more balanced drivetrain which gives better low speed/reverse gearing as well as better highway gearing.

people always complain about the amount of work or money but no one really knows how much actual work is involved to do this.
