Modifications & compatibility with newer parts

This is my first bit of activity here on Bigjimny forum so hi to all! I have a 2000 Jimny that I love very much and would like to modify over time to suit my work/ lifestyle. So better suspension, maybe just a 2inch lift. Better engine performance parts like exhaust, air intake etc. to hopefully get a little boost in power but more for efficiency reasons. And of course some body modifications too, however the kits I see online I really don't like but I love the brazilian model of the Jimny so where can i get those parts! (I added pics below of the Brazilian Jimny)


Compatibility Question:

• Can I get the transmission from a newer model and attach to an older engine (G13BB)?
• Can i get the interior dashboard from a newer model and fit it into my 2000 Jimny? Are the dimensions the same? Never mind wiring and buttons that can be figured out.
• Can i get seats & door panels from newer models and fit it into my 2000 Jimny?

Modifications Questions:

• Is it possible to get the arches, bumpers & side panels from a brazilian Jimny and install them on my 2000 Jimny? Does anybody know how to get a hold of these or similar?

Thank you!

The front bumper looks like the Chinese one available here:

I have a vague recollection that 2005 on have different mountings.
