z4 ecu will it fit into jap wrx
 

i have a jap wrx wagon it has a 4 plug e.c.u in it ,so can i put a z4 blue label ecu in its place ,and what can i expect from it,all i have on at the moment is a cat back exhaust or will it go bang,td 4 turbo i think ?:wonder:

The Z4 is not correct for a WRX Wagon due to the TD04 Turbo.
