engine swap on a 2001 tundra

im planning on putting an engine in my truck and i wanted to know what engines were compatible with it, the stock engine is a 3.4 6 cylinder

 

I’m assuming you mean 3.4?

 

3.4 V6, same as 4Runner and Tacoma from those years.

 

My bad yall right

 

Well these trucks also came with a 4.0 v6 with a 5 speed auto or six speed manual, a 4.7 V8 with a 4 speed auto or a 4.7 V8 with vvti and a 5 speed auto
So those would be your easiest swaps to do.

But the options are probably endless, these trucks have room for all kinds of engines.

 

You want an engine upgrade? I don't know what you plan on doing with the truck, but a fresh 4.0 v6 with a supercharger would probably be pretty awesome. Not sure the 4.0v6 superchargers fit the tundra or not.
