I hope this clarifies some of the confusion that is out there.

For busha's post to clarify the confusion, an aircraft 'manufactured
at the
factory in Poland' and a 'Homebuilt Aircraft' would have to be the
same
thing.

The correct answer is contact your local FSDO and tell them what
you have done and then ask them for guidance and see what you
get. You will find a different answer from each FSDO. As a
messenger only, I encourage you to contact an A&P and stay away
from the FAA and stop posting on public forum what you have done
to your aircraft.
The advice on this thread lacks research and study. It only counts
anyway when you have an accident and insurance will be looking to
figure out who to point the finger at. Untill then go for it guys. So
short sided!

I have made some changes to the instrumentation in the panel and a few other items. Can anyone confirm that all that is required by the FAA is a logbook entry by myself stating what was done followed by my signature and pilot certificate number and then a statement by an IA explaining they supervised the work and their signature etc.

An A+P can sign this off and you can do the work but you should have an A+P working with you and following along. I have no problem signing off work others have done if I know them and they get with me ahead of time so I can review what and how they are going to do the work but you will need to have it signed off by an A+P. Read your operating limitations you should find somthing in there about alterations.
