2JZ GTE Cherokee install

wahoo50 · Dec 20, 2009

Have a 1995 Toyota Supra twin turbo engine with automatic trans that I plan to install in my 1999 Cherokee 4 x 4. Question is - can the Toyota trans be modified with parts from the AW4 to fit my transfer case?

I have no earthly idea, but I sure am interested. That is a sweet motor.

man, that would be one SWEEEETTT azzz setup.

That should be a AW4 behind that Yota motor. I think Toyota has a different name/classification for it. Then again I'm not a Yota fan so i could be wrong!

It's called the A340. I think you would need to replace the output housing, maybe the shaft too.

AW4 and A340 are the same trans so It SHOULD bolt up! Bolt an AW4 to it and call it a day! I agree with everyone else in saying, Thats Badass and you should post a build thread! :yelclap:

ohhh my. if you do this, im claiming most badass cherokee on the street. is the motor stock? tell me your gonna build it up...

Thanks for the response & encouragement. I currently have a TE-60 turbo robbed from my Grand National on the XJ. It runs OK and I could continue with modifications but the 2JZ can make ungodly power for much less money. (My GN looks as stock as factory, but with the Stage II motor is making 748 hp, is so much fun to drive).

The 2JZ will bolt to the AW4 so I can install it and make it run, just don't think the AW4 can handle the power. Could have the AW4 built, just hate to leave a good 2JZ trans sitting on the floor.

Sure do appreciate you guys sharing any ideas you may have, even if they don't make sense, it might trigger a new thought.

Yeah, I'm gonna need some GN pics now!

The AW4 can handle the power, just get a fresh un-abused one. I have heard some big numbers handled by the AW4.

Yeah I had heard that myself. OP, How much power do you plan on pushing?

wahoo50 · Dec 20, 2009

With the twin turbos I can about 400 hp. I plan to remove them and go with a single one, other mods will be necessary as well, I think 550-700 would feel good in an otherwise stock XJ 4 X 4. Already have a 3" downpipe to tailpipe exhaust system and fuel management system.

Had one of these engines in my 98 GS300 Lexus, single turboed it along with other mods, was a real sleeper, expecially with the factory exhaust quietness. Even the gas mileage was cool.

Got to iron out the trans difficulties then attack the engine management system on the XJ.

Thanks for your imput and ideas.

im actually looking into this trans issue also im swapping in a lexus 4.0 four cam 32 valve v8. the trans appear to be the same trans as long as it is rear wheel drive i am not seeing any issue with this i looked into upgraded trans for my lexus transmission and it list the AW4 on the same list as mine. so go for it!!!

CherBear · Dec 20, 2009

The aw4 can handle lots of power. Somebody on here ran it behind a 401 IIRC. Ran 12.5s with that tranny.
I think you can swap the valve bodies between the Jeep and the Toyota versions of the the trans for firmer shifting.

This project is going to be amazing.

Novak does not appear to have much confidence in the AW4, in reading their descriptions on auto trans, they seem to prefer GM automatics.

MSPi · Dec 21, 2009

The toyota auto trans can only handle about 400-450whp. I would try to use the aw4 and see what happens.

thats because they make the adapters for the GM transmissions. Don't get me wrong, they are a great company, but the fewer different adapters they make the larger their profit margins.

they don't favor it as a transmission to swap to if you would need to do extra work. Bun in an application like this where no mating adapters or mounts are needed, then it should be a cinch.

pato castro · Dec 21, 2009

level10 transmissions can modify the Supra A340 to handle more than 1000 hp, maybe they can modify the AW4 too, it's basically the same transmission, a guy around here is installing a 2JZ engine in a Samurai (yep, a S A M U R A I) with the Supra tranny and the tailshaft from an AX15, here's a link to his project:
