V8 swap time?????

[Whitson Metalworks]

Found a 2000 tundra near me with the 4.7/auto, 155k. Its 2wd where the 4r is 4 so I'm not sure if that would cause trouble or if the 4.7 bolts up to the stock tranny or if my transfer case will bolt to the tundra trans? Anyways, its the whole fugly truck with a clear title, said to run great for 3000.00. Does that seem like a good enough reason to jump into this? I guess I could just buy the tundra and drive it too, but it looks ruuuuff.

The transmissions are different from what I understand. You would have to source an A341F from a Sequoia to get the multimode feature as well.

It's a small detail, but I would personally want a 2UZ from a 100 Series LC or 4th Gen 4Runner to get the stronger connecting rods for if I would ever have the need to supercharge it.

 

[Whitson Metalworks]

I don't want multi mode, just my plain ol sr5 j shift and 4x4. I keep reading that the 340 transmissions have the same bell housing bolt pattern? Maybe its an input shaft issue. Any idea if my transfer case could be mated to the tundra transmission? Also, I thought the 4.7 in the tundra was a 2uz? I know later years were more powerful but still called 2uz's.

Finish my roof rack first, pretty please before you jump into this swap!!

in all seriousness.. I would keep the truck as is for a pArts getter and utility vehicle for projects and such, may it be auto, household and so forth, depending on your needs

 

[T4R2014]

No idea if your factory transmission would match. I know the valve body needs upgrading if you supercharge. I would imagine that it would need some beefing up if you put a V8 in front of it.

There are two types of 2UZ's. The Japanese built has stronger rods while the US built version has weaker rods.

Yes sir!! I need another project like a hole in the head, its just deals like this are never down the road when you're looking for it lol. I'm afraid if it runs and rides good I'll like it and let my 4runner sit!

I looked into this a bit. As I recall the transmissions are the exact same size, just different (obviously, the Tundra has a 5-speed and we have a 4-speed). The engine shouldn't affect the 4WD/AWD/2WD besides computer issues, mechanically the engine doesn't have anything to do with where the power actually goes, that's what the transfer case does. I would research it a lot and read Singtoe's V8 swap thread a lot to know just what you have to do. Personally, I would wait for a vehicle that is totally wrecked and you can get cheap specific for the engine.

Though ff it was me, I would also rebuild the 5VZ with stronger internals and then put a twin turbo or large supercharger to pump out more than those V8s could dream of Good luck if you do decide to go for it :thumb:

It seems like the majority of people around here are all about keeping motor swaps consistent with toyota but personally I would much rather buy a 5.3 or 6.0 Chevy motor with a 4l80E or 6L80E. You can get a complete pullout engine, trans, computers, gas petal, etc. ranging from $150O-3000 or obviously the 6.0 is on the high end of that or higher. Those v8 Chevy motors produce wayyyyy more power than a toyota v8, get wayyy better gas mileage, just as reliable and long lasting, cheap, and very easy and cheap to mod for more performance. And basically just as much work to do the swap. Personally I have no clue why more people dont swap LS motors into these trucks.

 

[Whitson Metalworks]

I'm an LS fan, sure. BUT, getting the gm stuff to jive with Toyota stuff is gonna be tough and I want a clean look, not aftermarket gauges everywhere. I doubt the Toyota transfer case will work either which means more fab work, custom shafts, etc. I like my ac so that would be a huge chore in and of itself with an LS motor. Just seems like a lot more uncharted territory. If it was a trail rig, hell yeah, but I'm looking for a factory look/feel and similar DNA helps that along, I think lol.

 

[Illestreker]

The wiring might be more work but its definitatly possible to get a clean install other everything looking oem like gauges, ac, etc. sense your in Florida, google current performance. They specialize in motor swaps and do absolutely phenomenal work. The owner told me about 5k with me supplying motor and trans for a LS swap with everything looking and functioning as oem.

I love it!!


The swap should be pretty straight forward.

The Trannys are the same between your tunda and 4runner with the exception that the 4wd 2wd tail shaft is different.


You should be able to bolt the 2wd 2UZ bell housing to the 5VZ transmission. Use the 2UZ torque converter and all should be well .

The Tundra wiring should be much easier because there is no transponder key or dash swaps.

You will need to move the transmember crossmount rearward 4" to make the engine fit.

You will need to buy some limited drive shafts (front is longer, Rear is shorter) to make the new transmission location fit the new location.

Looking forward seeing what you do!

A GM motor in a Toyota is blasphemy.

Is the spline count not different on the tundra torque converter from the 4runner input shaft? When I was shopping replacment TC's last year i seem to remember finding a 27 spline and 29 spline version and was told one was tundra specific. This swap gets a lot easier if the tundra tc and bellhousing are all that is needed.

The tundra verter is about 2"s thicker then the 4runner. I don't know about the spline but if it is different, You swap out input shafts easily between the two transmissions.

Anyway. - You can not use a tundra TC on a 4runner.

This may be moot, but could the tail shafts be swapped?? That way the tundra motor and trans can be used and maybe not even separated. The seller isn't wanting to budge and the truck is too ugly to drive around, 3k seems steep for a parts truck with no other good parts lol.

Do it.

Buy the tundra. do the swap. Sell your stock motor, ECU, running gear, etc as a complete swap for 2nd gen 4runner or MR2 for $1200. Sell the Tundra rolling chassis for $900. Trucks are always top dollar.

So that leaves you with $900 in the investment.

BTW, The tail can be swapped but the tranny will have to be broke down and the output shaft swap out.

You can sell the rear axle to long travel Tacoma guys too!

 

[Whitson Metalworks]

Gahhhh, I want to do it, I just worry if the rest of the truck looks so bad how has the motor been maintained? He said the timing belt wasn't done which didn't surprise me. I'd hate to do the swap then have the motor or trans take a dump on me. EBay has several motors with lower miles but of course they don't include accessories. AND, I'd have to borrow a ride since its too rainy to ride the bike while the truck(s) would be torn apart. Damn, I'll try to keep talking him down, with the way the truck looks he won't have people beating down his door.
