JL MIG 29 - will fit 1 P160 up to P180 inside, in the middle

JL SU27 - will only fit 2 turbines inside, P60 to P80. Prototypes was flown with a P120 outside, but 2nd flights are in process with 1 P60 and 1 P70, since JL only has 1 of each engine. Engine bays are large enough to put 2 P80SE. More tests are still underway.

FB SU27 - P60SE to P70 or 2 Kingtech K-80 because the size are the same as of P70.

Hope that answers the question.
