Hawk XP TBO

Hi all,

I've been looking at the possibilty of buying and owning a 1977 Hawk
XP that is very near its 1500 TBO.

As I understand it, starting in 1979, the engine TBO went to 2000.

What is the difference and can the 2000 TBO engine be put in the 1977
Hawk XP?
Or can the changes that make it a 2000 TBO vs 1500 TBO be applied to
the enginer during a rebuild?

What costs are involved in making this change?

What other differences are there between a 1979-1981 Hawk XP and a
1977?

Thanks,

John
