I freepacked a FliK 266 with vtec into a teardrop that had a 190 sabre 1, not sure of the actual size. It was tight, but fit ok. Don't know how the ZP would affect the overall volume.
It will fit free packed for sure. I put an Ace 280 in a J4 once....long ass closing loop and a bit of stuff poking out but it works for a hop n pop. You will also need a bridle with a pin- (the J5's bridle incorporates the D-bag).
