In the case of the spyder, the key would be the 1nz XA bellhousing accepting the spyder differential. I think it probably would. At that point, you would use your existing axles and transmission mounts.

That's not really how VVTi works. The stock ECU is doing about as good a job as it can, it should vary based on rpm and load together. High rpm => retarded intake cam for higher VE, high load + low rpm = advanced intake cam for more power, low load + low rpm = retarded intake cam for lower VE and lower pumping loss. Don't mess with it.
Yea I wouldn't be surprised if some of the 1NZ bellhousings worked, but I still have the exhaust piping to worry about afterwards. In California a custom exhaust isn't going to pass visual inspection for smog, even if the puny looking 1NZ doesn't raise an eyebrow
