Toyota 5.7L V8 into an FJ40

[toyotalandfj40]

I have been looking for a new engine for quite a while. I was looking at the 12H-T and the 1HD-T, but it was too expensive to get one all the way into America. So, I started looking into the gas spectrum and found some, on the top of the list is the 3UR-FE, the V8 inside the new Tundras. I then looked for some donor cars, a wrecked tundra, and found a lot of them. Now, I wish for a part time 4WD not all time 4WD. Which transmission can fit onto the engine, I already now that I need a bellhousing adapter, but I mean by which flywheel will fit and which transmission is sufficient.

Another question, from what I remember, in a manual transmission, the flywheel is attached to the crankshaft. The flywheel has teeth on it that connect to the splines on the transmission input shaft, correct. So, you can custom fit a flywheel onto the engine and use the original FJ40 4-speed, which I would rather install the H55F, the 5-speed.

no one make the adapter you will require. Been asked and same answer has been presented for several years.

I bet you can have the bell housing fabricated, I have a guy with a CNC

 

[dgangle]

Add in a $10K pattern and a foundry that will take on such limited work and you are in biz.

Anything can be done but at what cost? Time + effort = $$$. Lots of available & proven V8 conversion options out there to people that will poney up. Research and read. This comes up periodically so see where others have hit the proverbial brick wall.

I dont see what the big deal is? you can buy th700 adaptors to fit onto the engine, and kits to bolt a transfer case to the back of a th700

For the Toyota 5.7, or the Chevy 5.7?

 

[dgangle]

whos' on first?

I have nothing but this link, find out who owns it and see if it will work:

1UZ bellhousing and flywheel

It is for the Toyota 5.7 L V8, it has better performance and torque than the Chevy 5.7L. Also, it is Toyota, trying to keep it within the same brand. Also, I'm looking for a MANUAL transmission, to run with the engine, not an Automatic....

Being practical about this, it isn't going to happen. No adapters, no flywheel, no clutch, incompatible electronics (like the infamous electronic pedal). I would forget it. For a huge investment of time and money (and headache) you might get it going, but then you have missed 5 years of driving your truck. There is a lot more to a bell housing than a buddy with a CNC mill.


You are pretty much stuck with Toyota 6 cylinders(gas or diesel) or something that is Chevy compatible like a SBC or a 4bt.

You could possibly adapt an entire drivetrain out of a 100 series if you just have to run a Toyota v-8.

If you were going to do this, the only way I see it working is getting a wrecked Tundra. Pulling the body off, chopping the frame and adapting the FJ40 body to fit. And then doing a solid axle swap with a diamond housing. Lots and lots of work to get it right.

You can do both the 4.0L and 4.7L V8's a little easier. I have the 4.7L V8 in my 55. But it was a lot easier than trying to adapt a non-Tundra transmission to the motor.

If you are thinking about the 4.0 or 4.7L check out lextreme.com

I admire your integrity. I hope you're able to do it and would love to see a build thread about it.

WTF does an engine swap have to do with integrity? So if he chose to install a cummins turbo diesel he would lack integrity?

 

[bulldog11267mad]

It is possible to do as long as it isn't to wide to fit in the engine bay. I don't know what is involved with swapping in a manual transmission and making fit. I have swapped the 5.7 in a older 2003 tundra. It is alot of work and took me about 8 months. now if i had all the parts i needed i could have done it in about 3 months. what would worry me is the exhaust hitting the frame.

 

[effjay76]

Sure there are easier ways to get a toyota v8 in there, but i would love to see this done. I have dreamed about this swap since the 3ur went into production.

I disagree, I've got a couple of buddies with TechShop memberships ... I think a chunk of aluminum and a water jet table would do it Now would it be easy ... no ... but it would be cool. I've hear that engine is really wide -

This would be one of the craziest(by that I mean coolest) 40's. I own a tundra and am amazed all the time by the 5.7! Tons of power and pulls anything! Cant say the same for the transmissions though. Good luck! I would be more than interested to find a way.
This topic has been discussed here at work as well.

By far the easiest way to do this would be to skin a tundra with the body panels from something else. There are a ton of integrated systems that would be unhappy without the trans, axles, yaw sensors, etc.

 

[zags]

Just use one of these Camry engines

 

[1MAC]

No doubt that would be an awesome vehicle, but it sounds like something that would require help from Toyota engineers!

It would probably be less expensive to buy a 200 series LC and be done with it.

IIRC the new UR motor uses Toyota CAN-BUS system. Pretty much everything, from the Airbag sensors and ECU to the emissions controls talk to each other and to the ECU. Makes this sort of project much more difficult.

As per a previous post, it would probably be less effort to put a modified 40 series body on a tundra fram and see what can be done to retain stuff like the airbags.
