I stand to be corrected:

I repeat   "......factory certified ...... this is not the same as being a Certified Aircraft."  

"No mandatory engine replacement at 2000 hours or 15 years

True there is no "mandatory" replacement of the engine when it reaches its calendar/service hrs TBO and the aircraft may continue to be flown, with the engine subject to enhanced "on condition" inspections. However the aircraft will no longer be legally available for hire or reward, until such time as the engine is replaced/zero timed.

............certified aircraft (this is not an S-LSA) so the engine can run on condition after it reaches TBO of 2000 hours or 15 years calendar"

I do not think there is a direct link  between your factory certified aircraft & the continued use of an out of TBO engine.

"........................being forced into E registration for this aircraft!"

Nor has the E registration have anything to do with this. E registration is for aircraft that have had non factory approved modifications made (I assume yours has no such mods).

"............certified aircraft (this is not an S-LSA) so the engine can run on condition after it reaches TBO of 2000 hours or 15 years calendar. No mandatory engine replacement at 2000 hours or 15 years or being forced into E registration for this aircraft!"

I do not think this statement is correct.

First it is not a Certified aircraft  - this is a GA term/concept. It may be factory built and factory certified but this is not the same as being a Certified Aircraft.

Certainly you may indeed be able to go past the 15 year/2000hr TBO  to "on condition" (conditions apply) BUT as I understand it the aircraft can not be used for hire/reward, if this option is chosen.

A lot more info require eg engine/airframe hrs - airframe/engine build years- what work was done to convert to TW - propmanufacture & type/model - last flown- empty weight - fuel capacity - last 5 year rubber replacement - there is more than one Pulsar model, which is this
