I've got a 3.0 manual 89 4runner that's been sitting for the last ~15 years that I would like to finally get up and running again. I am wondering, are 3.4 swaps still viable in 2024? I've been looking at salvage options, but it's pretty hard to find something that isn't high mileage these days.

 

I would think if you can get a reman 3.0 you can get a reman 3.4. A 3.0 would be a direct replacement at least but you would still have to deal with what has been sitting all these years. Such as bad gas in the fuel system, rotten hoses and belts, etc.

The 3.4 would require the same plus the swap work and expense but you'd have a better engine.

LS swaps seem to be going in everything these days. Would that be an option for you?

 

Yes. https://toyonlyswaps.com/
That's what I'd do if it was my rig.

 

Is the 3.0 in it now serviceable?
