Default X15 to X17 swap

Has anyone replaced the x15 injector pump for a x17? My budget wont allow a p7100 swap.

x17 is HO pump and will get you a little more bottom end due to more aggresive cam, but less overall HP as teh plungers/ pistons are smaller.

get bigger injectors--- +300HP are only about $500.
