I'm just curious about what kind of engine (with more power) will be the easiest to swap into my 91 4runner?

V6 3.0L 3VZE

 

Well you could buy a 3vze with 190 hp from a bunch of places on the web, or look into the 3.4 swap. Those will be your 2 best options for "bolt in"

 

X2 I vote 3.4 over another 3.0

 

A little more to a swap then just bolt it in.

Read through the 3.4 swap section to get the idea.

Then it depends just what your end goal is.

 

I wish i had gone with a 3.4 instead of the 3.0 (twice actually) in the end I didn't save any money (from what i estimate/found what 3.4 swaps cost) and just kept all of the headaches associated with the 3.slow. If you're mechanically and electrically inclined then the swap should be a piece of cake as long as you get all your ducks in a row! Also check out Toy Only Swaps. could be an option http://www.toyonlyswaps.com/Page_2.html or DIY http://www.toyonlyswaps.com/Page_5.html

 

3.4 all day

Toy only swaps like stated above and off road solutions ors
has installation instructions in the tech info section

 

Looks like the 3.4 seems to be the best option. I did hear something about a lexus engine once... If any one knows anything about that I would be interested to know more, but I will read up on the 3.4 swap. Thanks!
