Beefin up the Yak

I'm hoping to get enough time to do a round-the-world trip, in a Yak-18.... but it needs some modifications.
I want the engine changed from a M-14P (360Hp) to a M-14PF (400Hp) or even a M-14R (450Hp)
Can this be done by changing the engine values in the Aircraft.cfg file to the new parameters or do i need to change more.
Can someone PM me an Aircraft.cfg file with the item descriptions for propeller aircraft?
