The hi-performance endorsement is for the pilot, not the aircraft.
Experimental/non-experimental is not a factor.

Also it is for greater than 200 hp, so a 200 hp does not require it.

FAA requires hi-performance endorsment for 200+ engines.
Is that requirement only for certified planes?
One CFI indicated that it is not required for experimentals.
