I've modded the Turks to give them a helping hand, but it didn't help much.
I gave them lots of florins and I upgraded Rum with all the buildings it needed to make Heavy Jannissaries. All they had to do was hold on to Rum until the High period. Silly Turks left Rum unguarded and the Egyptians waltzed right in. You may want to mod a province (or two) away from the Egyptians and give it to the Turks.
