#EXOTI1CSTANCE :
2uz-fe Would be unique for that 180
Actually been thinking about a 2uZ-Fe!

You can also use the Jz series cuz toyota used this on different models But if you go with the european engines ill recomend the 4.4 V8 from the 5 series e39.
I just pulled a 1.5jz from my cream 180 a few months ago to put in the big single RB20. Engine is sitting at the shop so I could drop it in if I really wanted to. I do like the BMW engine idea though!
