LX450 engine swap?

What year? IIRC the trans is electronically controlled, so you would need the entire harness and both the ECU and the TCM. I drove an LX450 (FZJ80) and it was pretty powerful for a massive truck. Bad fuel mileage but in a mini it would likely be better. Seems like a very large engine to fit into a Mini, though. Why this particular engine? Seems like a lot of electrickery for a trail rig. They also have issues with head gaskets.

Why this combo?
I'd like to stay all Toy and it is a :smokin::smokin::smokin: deal (if I can make it work). Everything from the gas tank to the ignition key, wiring, computer, and everything in between. Basically everyting except the body, frame, suspension. More than twice the power of my 22R, it's injected, auto tranny (which I prefer)
It's a 4.5L I6. How does it compare to the 7M for size? Tranny and Tcase have been rebuilt, engine has about 150k on it.

I've heard/read a lot of hearsay about these drivetrains.
That vintage trans is a Aisin A340 or whatever TLC specific variant it is. Supposedly pretty much the same trans as the AW4 in the Jeep XJs. I only mention it for anyone that happens to search the forums in the future.
That said, that means that you may be able to get past some of the electronic shenanigans via the use of an aftermarket shifter (see http://awshifting.com). If the TLC setup is similar to the Jeep specific setup then the transmission has its own stand alone computer that can be used independent of whatever engine electronics you may have. A `97 LX will be OBD2 compliant which means that codes may be thrown when you switch the controller to something like the awshifting unit if you keep the engine ECU. This is what happens with the AW4s used in the 97+ Jeeps anyway; the Jeep engine ECU throws codes when the trans is switched to "manual" mode.
Conversely, there is a guy (JJacobs at NAXJA.org) using the AW4 w/ TCU behind a carbed (Holley EFI maybe?) AMC 401 without any issues. The controller works the transmission fine.
For the engine I dunno. It has a reputation for being a thirsty engine that will last "forever". Sounds about the right mix for a TLC, no? the electronics may be integrated into other stuff, I don't know. The last ones ~`97 have a reputation for blowing head gaskets at ih8mud.com but I think that might just be anal owners getting their knickers in a knot and being proactive. The Toyota specific replacement head gasket is supposed to cure the "problem".
I like the 1UZ as well. Nice, light, small, supposedly cheap to source (haven't checked myself). I dunno about the electronics. I forget a bunch of stuff that I read at lextreme.com. Again, easy to use these trannies (A340 or AW4 if you wanted to go to a NV2xx t-case with centered rear output) with these engines. It's all in the bellhousing supposedly. There are megasquirt setups for the 1UZ setup supposedly but given your sig line probably not a good idea.
Thing about the 1UZ though is that for all the neatness and such at the amount of effort and money to get one installed you could probably do a Generation III or IV Vortec SBC w/ 4L60E and not be caught having to source soon to be EOL'ed parts for a lot less money.
There's probably other stuff I meant to put in this post but real life calls at the moment.
FWIW, I love the LX450 / TLC FZJ80. Sometimes I kinda wish I had gone that route instead of the XJ but at ~15 mpg versus the ~22 mpg I get now as a daily driver I guess I'm better off with the more lightweight vehicle that I have to re-engineer the hell out of to get close to the strength of the stock 'Cruiser. I could buy a hell of a lot of gas for the money I'm putting into the XJ...

I looked into the 1UZ swap. I'd love to do this one.
This engine is all aluminum so its light. It is super strong and idles very smoothly.
I have found them in the area for about $700.
there are no manual versions of it around here or in Japan AFAIK.
it was available in manual in Australia though. I think i'd prefer it automatic anyway. we would need to find a A340F to bolt up to it.
It would be find to tune up a megasquirt.

Just looking at options. The swap wouldn't happen until next winter anyway. Getting it is just part of a larger deal. Trying to make sure that it will work so I don't end up truckless again

Sure I'll take it, easier than building a flatbed

Yes, just throwing out options.
"home made" EFI computer.
Jon, you don't want to go there.
Yes, or you can convert it to part time. It's a strong case, jsut sucks fuel being AWD and all. But then, for a trail rig, does that extra 1-2 mpg really matter? You won't be travelling at highway speeds much anyway so the difference in mpg might not even be that high given intended use. Also, the TLC case is offset to the right for both front and rear outputs - mini truck rear axle centered input needs to be considered.
Just thinking about the 1UZ EFI ECU thing. I've read (@ lextreme.com?) that the engine ECU doesn't care if a manual trans has been swapped in.
Also, just to throw the idea out there... If the AW4 is more or less electrically compatible with the Lexus A340 then there is your 4x4 auto box for a 1UZ swap. Swap bellhousing, TC, flex plate and call it done. I don't know if this will work - just throwing the idea out there. I'm certain it will bolt together. Then it's "easy" to bolt on a centered rear output t-case.
Oh, and for the Toyota purists - the AW4 and the A340 are the same transmission for all intents and purposes - built by Aisin-Warner (hence the "AW" in AW4. The AW4 has the Dana 300 style mounting flange.
HTH
Here is the lexus V8 for $750.00

Go to www.supracharged.com, he makes the bellhousings for manual tranny's

Damn, sweet deal.
Think it'll work in my XJ?

I'm only considering this because I can get it cheap. Also, if I do it, I will keep the auto trans. If I don't get this particular combo, I'll wait untill a 4.3 falls in my lap.

Maybe I should do this instead?

If it was $500, I'd make it fit in the Toy!!!
I understand
My Step-Brother has an only astro van with a 4.3 he might be willing to part with...
7M is not bad, to do it without a body lift you have to clearance the firewall for the EGR or just take it off... IN the front you have to run pusher fan on the outside of the rad cause there is no clearance on the inside for one.
Weights:
7MGE - 440lbs
4.3 - 425lbs
350 - 600lbs
1fz - 584lbs
22R - 315lbs
And here is another option for you (the one I was going to go with until my wife dropped the 7M in my lap by crashing her car lol)
5.0L Ford - 450lbs
