Thoughts for that new engine, depending on who's doing the modifications, F404/F414, RM12, EJ200, M88. Personally, I'd go with the EJ200 just to be contrary. If it's the Israelis doing the modifying, the F404/F414 would be most likely, the Swedish, as in my thought, the RM12. any other European country, the EJ200, and, finally, France, the M88. I could see it as an upgrade of the Spanish ones with them installing an EJ200 as part of the upgrade.
