In Australia t's dubbed as a 1.5JZ conversion. As you said, it uses the 1JZ head (better flowing) with the block of a 2JZ (for bigger capacity)... only thing is it may cost an arm and a leg... I'm not sure if you can use the SC300's 2JZ block or if you have to use a 2JZGTE block, probably the latter though.

its not "better flowing" just that its built for a 2.5L engine so its made to provide for air flow up top... Ideally a 2jz head be a better match for a 2jz? simple enough eh?
On a side note it does swap right on, but the manifolds are not the same, so good luck finding 1jz upgrade kits for turbos. Turbos are ceramic as well, so if they blow, good luck finding those too
... Not to mention compression of GE, oil squirters, oil/coolant lines etc etc
better to just drop a 1jzgte in all together IMO
