Ye olde OccasionallyRunner
So I have a ‘95 4Runner with 4WD with the 3.Slow. Now let’s say I want to up my power, responsiveness, and gas mileage by swapping in a 1UZ-FE. I have the A341H transmission. Now, the A34XX series was used in the LS400 as well, but obiviously, Lexus never made a 4WD LS400. So, aside from mount modification and trans adapter plate, what else would I have to do to make this work. I’ve seen it done on 2WD examples, but my main concern here is with the ECU. It says “3VZ-E,” “4X4,” and “A341H” on the ECU itself, so does this mean there would be compatibility issues with an ECU from a 2WD LS400? Not that I have the means to make this a reality right now, I’m just wondering for future reference. Thanks!

I’ve talked to somebody you has done this, and as long as you are okay with keeping the auto, pretty much everything needed can be bought and the original ECU can be used, so long as you pick up a pre-1995 1UZ.

Oh, ok. That’s actually really surprising. So it’s basically plug and play?

IMO auto is better for off road anyways... Not having to restart your engine all the time is pretty nice. Lets you concentrate on your lines more.

My friend wants me to 1UZ swap mine as well.

AFAIK

But why? The TRD/Eaton supercharger would reliably boost power levels to 1UZ+, along with being cheaper and torquier.

I said he wants to. I never said I’d let him.

I don’t off-road recreationally, but 4WD is always nice to have. I don’t even know how to drive manual anyway lol.

Because I don’t have the time or money to do such a thing. And if I were going for more power, I’d put the TRD supercharger on it.

Fair enough. And I just remembered you have the 5VZ, not the 3VZ so the engine you already have isn’t totally awful.

Used to work with a guy who said why like that.

We would always say it like that when he wasn’t around. For a while, it was how we answered every question and most statements.
“Hey, can you help me with this box?”
“WHY?!”
“When’s break?”
“WHY?!”
Etc
