supercharg 5vz or 2uz swap?

Hey everyone. Been looking for some more power, I was wondering if it makes more sense to supercharge my 5vz or to just v8 swap it? It will allegedly make about the same power, but the 5vz will be at its max and I could push a lot more power with the v8 if I wanted to in the future. The thing is my v6 only has 45,000 miles. What will need to be swapped over from a v8 truck, and what can be used from my v6? If I v8 swap it I will most likely build the engine from the block up, keeping it all fresh, and then having minimal downtime. If I where to just do a simple swap, not modifying anything else on the 4.7, how much would it cost? Thanks

 

So a supercharged 5vzfe with the latest Magnuson TVS1320 ($4k) will get you about 260hp and 260tq or you can find a used gen 1 (grey) TRD or gen 2 (black) TRD/Magnuson supercharger, which will net a little less HP.
VS a non-VVTI 2uzfe with about 245hp and 315tq.

You gotta ask yourself a few questions.
1. How much power do you need/want?
2. How much money are you willing to invest?
3. Do you have an auto or manual now?
4. Would you rather do an engine swap or bolt on a bunch of goodies?

If you have the manual transmission, the money, and just want more power, but dont mind buying premium gas and some other URD goodies (for even more power), and because of the mileage, I'd say the supercharge it.
If manual transmission get the URD short throw shifter.
If auto get the Transgo shift kit and a transmission cooler.
Either way if you supercharge, get Iridium spark plugs, upgraded thermostat, URD 7th injector kit (comes with piggy back ECU and can be bought as a bundle with the SC for some savings) and URD SC pulley, URD crank pulley.
I'm honestly not sure if the supercharger comes with the thermostat and spark plugs or maybe the URD kit includes em. Either way you'll need em. For even more power you can do a methanol+water injection, and headers into a single exhaust. Supposedly, all those goodies should get you about 300hp to the wheels.

If you have the auto, it's the same transmission as the V8. The 2uz takes regular gas. I'm not sure what a non-VVTI 2uz goes for price wise. Probably wise to also get a transmission cooler too and might as well do the shift kit.

You'll still need new engine mounts for the v8 and I believe the transmission cross member is not in the same place (although it should be the same size and shape if you have an auto already). So be prepared to cut and weld. You'll also need a new ECU. I'm probably missing some important stuff, but someone else will chime in.

My opinion: the V8 is pretty awesome, but I've wanted a supercharged 5vzfe since I was 15, I don't know how to weld and never swapped an engine before, so I'm biased to the bolt on supercharger with all the URD goodies for a decent bit of power and money. Just be prepared to pay for nothing less than mid grade gas, but likely you'll want the high grade gas for the most effect.

Another thought is since yours is an 02, you may be able to swap just about any engine you want without worrying about state emissions BS. So maybe consider your options. In TX you'd be free of any emissions BS in 2027 (assuming you're even in an emissions county or state). My 03 will be free from inspection in 2028, but my inspection is in January, so 2027 will be my last one and technically I could get it done for the last time ever up to 90 days prior to January 2027.
I assume if you are in an emissions place, you could do some shady stuff to swap a junkyard VIN if necessary. Not that I'm advocating that.

 

How much money you got?
Like @assdog said, too many variables and unknows to give you a definitive answer.

 

I would have to second what @455h0le_dachshund stated. Gotta weigh out your options. I've done an engine and transmission swap, and there were times I was like fuuuuuuh, why am I even doing this, but I still finished it in a timely fashion like every government project, well over budget and well beyond the timeframe.
As for what can be swapped over, just the body, you will need a complete 4.7 Tundra sitting there, best way to start your swap, since everything will be there.

 

For $4k just get a LS

 

exactly my thought, but I feel like I beat that horse to death every time a similar topic comes up.

 

Is in pretty simple for a swap tho? it may be 4k just for the motor but then you start snowballing

 

VVTI 4.7l engines make 270- 280 something hp (I thought, but now I can't find confirmation). Dirty deeds long tube headers give 40hp and 50tq to the VVTI, and only 30 hp and tq to the earlier ones. So unless I am wrong you could have 300+ hp with the 4.7 V8.

On a different forum there was a guy who was building out a first gen prerunner, his engine idea was to run one out of a supra, can't remember what year. Apparently it would bolt right up to the stock transmission no problem and could net pretty big hp numbers, he was saying 500+. I have done no research to confirm that, but it seems cool. He never finished that project so just food for thought.

 

Keep in mind if he went VVTI, he'd need an A750 5spd auto transmission and 05-06 ECU. Also worth mentioning the HP numbers from Toyota are at the crank, not the wheels, and apparently the descrepancy from 282hp to 271hp on the VVTI was due to the method Toyota used to measure the crank HP. Supposedly 271hp is the more accurate number of the two. I'm guessing Dirty Deeds numbers are at the wheels. I've got the LT JBA headers from DD on my 03 and my 06. Hard to say how much difference it made on the 06, because it already had 33's and full armor, then immediately after installing headers and DD race exhaust, I got it regeared to 4.56.
But to put into perspective, a stock 03 AC Tundra 0-60mph is 7.8 second, while my 03 has done it's best 0-60mph in 6.1 seconds.
My 06 best 0-60mph is 7.8 seconds. But again, it's got a lot of extra weight and bigger tires.
A 2uz might be able to reach 300hp to the wheels with a supercharger. Options are limited to used TRD SC, Bullet SC (intercooled, technically for 2uz Land Cruiser), URD SC kit (technically for GX470 and 2uz 4Runner) and Elate offers adapter plates (intercooled and non-intercooled) for a Harrop TVS1900, Range Rover TVS1900, Eaton M90, M112, and M122. You can find those in a junkyard or FB market place, Craigslist, etc.

Most people say not to go above 5-6lbs of boost on the 2uz without upgrading the rods. @Sirfive would caution you not to push too much power with 2uz because of the 2 bolt main caps.

 

junkyard 5.3 for $500-1000. You got $3k for rebuild and all elextronics

 

That's not an LS

 

LS/LQ/LM, all the same add-ons/upgrades are interchangeable FTMP. You can convert an LM7 to be very close to an LS1 with limited funds. This is why I hate that "LS swap" has become the norm and usually say "GenIII swap" myself instead, but ...

If it were me, I'd probably go LQ9 and find a pull from an Escalade or similar. Get it with the transmission. I don't know if there's any bolt-on engine mount adapters for 1st gen Tundras. Transmission mount is easy enough to adapt. The donor truck would ideally need to be 2WD and I'd assume you'd be using the GM trans that was mated to the LQ9.

I'm guessing you can get out the door at $2,500 on a decent-mile LQ9 and trans combo with ECU & harness. You'll likely need someone to repin the harness, potentially program out VATS from ECU. Not sure how to address/adapt to the Toyota ECU wanting to read misc sensors. I've only ever GenIII swapped emissions exempt and/or pre-OBD vehicles and/or track vehicles.

 

@the_white_shadow swapped an LQ9 iirc with a manual into his Tundra

I enjoyed reading this entire post Most everything suggested for the 5vz is what I currently have on my 5vz. It's an '02 Taco though. 5spd with Magnuson SC and URD 7th injector. When I had it running, it was amazing! Currently I'm in the middle of an engine rebuild/swap(pending funds) but when I piece it back together, it's gonna be better than ever.


My vote is for a supercharged 5vz

 

I forgot to mention headers and single exhaust in my list of supporting goodies for the SC'd 5vz. And if they still make em, an Airade modular intake tube to stock airbox

Sweet taco

 

Sell your truck and buy the one you want with a 4.7 in it. Done.

 

Thank ya thank ya!

Thanks for that piece of info on the intake. I got rid of my AFE hot air intake and luckily I stored away my deck plate modded stock air box so this Airaid intake tube will be an improvement over stock. Just checked and they do still have it available. Gonna look into possibly using that deck plate mod and running an extra inlet tube from the grille(kinda like the Stillen for the 5.7)

So many things I want to do to my Tacoma but can't cause my Tundra empties my wallet

 

Glad they still make em for the 5vz. I had one on my taco and have one on my tundra. Unfortunately they stopped making em for the 2uz
