quick question if coil packs are the same?

[timmy_tam]

just a quick one
i've got an s2 VN engine with the 3, round coil packs
will a spare s1 engine with 3, square coil packs. is it a straight swap or is there voltage or fitting difference, etc?
thanks

Same same.

if you change the coils from single 3 stack to an individual setup you have to change the dfi cradle underneath to match up with it
