Is this the same engine that's in our trucks?

No. It's slightly different in Lexus. Also notice the years.
I did notice the years, but I was just curious if it was the same engine, just tuned differently. I'm assuming this engine has been around for a while, before it was put in the Tacoma. I could be wrong.

The 3.5s in the other cars do not have atkinson capability. It isn't the same.
 
Let’s all cross our fingers and hope they don’t have the same carbon issues as the is and gs from Lexus same engine and at about 100k or more it will start to misfire.!!

I think the problem there was lack of port injection. The 3.5 in the Taco had port and direct injection. There should be no oil vapor buildup in the intake tract.
