What's XMSN? Since you're talking about swaps I imagine it has something to do with mounting lol.
I believe I mentioned this 2 years ago or something but someone had swapped a 1NZ-FE into an MR2 Spyder with a C60 transmission swapped over. He said he was getting mid 40s mpg vs. high 30s on the 1ZZ. However, he had to make an adapter plate, and then cut away at some metal to allow the starter motor to fit. The stock 1ZZ ECU ran the 1NZ just fine when equipped with the original sensors (MAF) and injectors. To compensate for power he added a pretty big turbo and apparently it was more reliable than the 1ZZ at equivalent power levels and overrevving to 8000rpm stock.
The other good thing about this swap is that the NZ is quite the featherweight at ~190lbs with all dressings, fluids, etc.
If 2ZZ-GE swaps weren't so easy (you can make them pretty eco by regrinding the low rpm cam to a super long duration), I would strongly consider transplanting Prius cams into a built 1NZ bottom end for a high rpm screamer that gets great mpg during typical driving. Remember, "Atkinson cycle" cams and high rpm power cams are very similar!
