What's the purpose of a different manifold?

off-topic. How difficult would it be to transplant my motor/trans into a Prius?

Atkinson cycle engines don't have large powerbands but rather a small efficiency zone, so whereas a traditional otto engine is probably about 27-33% efficient between 2-5.5k a Atkinson engine is 35-39% efficient between 4-4.5 rpms. So because it uses a hybrid drive transmission the engine never really cycles through its rpm range but rather like a CVT just has a gearing change that keeps the engine happy but still allows acceleration while the electric engine is providing the majority of the mechanical drive.

I don't think the transmission bolts up to the 1nz-fxe, it would be far simpler to get an electric engine/generator and attach it to the crank snout like a supercharger to get some extra assist that way. That kinda the way honda currently does it with the CRZ/Insite
