Toyota

i just learned that 2jz's are still cheap, i was looking at them to compare to the barra engine (but thats a whole other topic), and i learnt that the 2jz is available in a lot of other obscure cars that havent got the bro tax, like the toyota progres, BUT they use another type of 2jz named 2JZ FSE, whats the difference and most importantly, can GTE mods work on it ? because that looks too good to be true.
