2jz gte swap

So for those of you who don't know, I blew my HG a week ago. Two weeks my bad. Anyway, I searched eBay and there's a few of the 2jzgte available.

For those of you who say it lacks torque, it has 100 more ft/lb than my 3fe & 100 more hp as well.

Why won't it work? I fail to understand why a more powerful engine is a bad swap.

With tuning & exhaust I can easily pull a reliable 450hp & 400tq out of a 2jzgte
 
280hp
340tq

For less than $2,000

Would it bolt up to my a440?
 
It is a matter of where the power and torque is made. The 2JZGTE is a high revving engine, some of the built motors rev to 9000rpms. So while yes they might have more power it is much higher in the rev range, really the last thing you want to have to do when you are crawling.
 
Experiment! Give it a try... Let us know how it goes

This exactly...... wonder why every truck/suv made by every major company the world over, including toyota, use engines that have a TQ that comes on just off idle???


Hell I might as well put a turbo GSXR motor in my truck


The supra motor is a great one but not in a suv. While you can gear down for the trails (although there aren't many options for the 80 and still not enough to make a huge difference) it will be street driving that also suffers.


A supras TQ lines are not that good for off roading... you could run the risk of breaking parts easily when all that TQ actually finally starts hitting and your revs are off the chart trying to crawl up rocks.

A diesel, V8 or building your current engine up is a much better option.


While a turbo kit won't make the 3FE a rocket ship it will make it a whole new beast. I actually have a kit i'm getting rid of because it won't pass the CARB when I move back to Cali.


But it's your money.... go for it.

Just my 2cents
 
There's no rocks in Texas. Well, anywhere near Houston

I'm not a crawler & really never have any plans to be one. Geographically limited.

I do, however, hit plenty of trails. Around here we have tons of sand & mud where wheel speed is a necessity.

That said, could my a440 handle the power @ those rpms?
 
I'm not sure if it will.. But only one way to find out. And if it does blow up just build it to handle the power.
 
So the supra guys have been running the A340 behind some pretty well built supra's. I can't remember if it is Titan or Boost logic that offers a built A340 for $2200 that is supposed to handle 800hp. But the A340 and the A343 that the 80 uses can't be too much different. If I break my transmission I will probably send an A343 to them and have them see if they can use the same tricks as the A340 on it. Unless someone beats me to it..... ;)

Don't listen to the haters! I think it would be a great swap. You could pick up a JDM 2jz-gte for less than it would cost you to replace the head gasket on the 1fz. (if you do it right)

Torque is meaningless. The only thing that matters is horsepower. You can infinitely change the torque to the wheels with gearing. You can't change HP. (without changing the actual output of the engine)

You can get a 2jz for less then a couple hundred bucks ? How much does it cost to fabricate parts and get everything turn key ? As far as the torque is meaningless comment I think you should talk to Ford, Dodge and GM about your ideas. Those fools have been running 6.5L and up motors in there full size diesels for years. I guess they just don't know any better ! ;)
 
Actually the OP has an interesting idea. On paper it should work well, putting a 2JZGE in place of a 3FE. The stock twins should work quite well in this application. The 280hp/320tq is also quite conservative, even for a stock supra.

Rumour has it that the Japanese feel that its immoral to have a car with more than 280hp so that's their maximum advertised hp, which is to the wheels and not at peak rpms.

If you had a 1FZ I would not consider the 2JZ.

I would think that a UZJ80 would be more fun than a JZJ80 because low rpm horsepower is what feels good in a 2.5t beast.

Haters gonna hate. A stock tune 2JZ-GTE should work fine. Easier to bolt up the A343 though because the bell housing is already available. Not sure how easy the A440 will work, but a bit of sleuthing should give you the answer. Just find out if the supra a340 bell is the same as the Landcruiser a343 bell housing.

Good luck with your project.
 
Talk with Bowtiestang he may have a bellhousing
 
I'm a long time member of Club Lexus - talking with some of the soarer/supra guys ab fitment.

Everyone is scratching their heads - apparently nobody's done it for the reasons listed above. Since I'm not a crawler it may workout well.

We shall see.

I'm looking for another SC300 to build as well so I may put the gte in the sc and the NA Ge motor in the cruiser. Who knows - I've got a lot of research to do B4 deciding on anything.
 
Is anyone on here a regular on pirate4x4?

That may be my best bet.
 
Lots of guys are putting turbo's on the 2JZ-GE motors and pushing them up to 700hp on stock internals.

What questions are you needing answered? You can bolt the A343F to the 2JZ in place of the A340. You could even bolt an R151 if you did:

1JZ bellhousing for R154 tranny
1JZ flywheel
7m clutch (same as 1jz)

You might even be able to get decent low end power with a very small turbo something like a GTX2863, running 10psi should be able to make about 370ft/lbs by 2700rpms.
 
I don't want to ditch the a440

Soy question is, will a 2jz bolt up to an a440?

I have no interest in a manual transmission.
 
JDM doesn't have EGR valve, but I could care less.

What's SMOG? I'm not in Cali!
