you can rotate the inlet connections on the tb to match the angle of the 1nzfe throttle body

The Yaris throttle only opens to 80% at WOT IIRC, so anything of a larger diameter will be limited as well, although you're increasing the amount of air to the engine regardless.

My 1ZZ TB has been on for over 5,000 miles with no issues. No chip swap, I just let the ECU do it's thang. No CEL either, although I had one initially so it might have gotten tired of displaying it on the cluster.

I have a high idle like tk when cold, (2.5K) but it goes away when the engine warms up.
