1NZFE - the most boring engine?

You can slap all of the bolt ons you want to a 1nz but unless you do a full on build with a custom tune like Jason has, it will still fall flat on its face above 5.5k rpm. I had full bolt ons on my 1nz I/H/E plus golden eagle intake manifold and above 5.5k rpm it stopped pulling hard.

This is where the 2zr comes in, much better area under the curve and with dual vvt-i and pulls much harder to redline.

Someday I'll get that 2ZR swap going.
