Porsche-noob-91

I'm looking for an exhaustive comparison between a Porsche 944 Turbo (951) North American (NA) car versus a Rest Of World (ROW) car, specifically for a 1986 model but a more exhaustive summary for older cars would be welcome too.
I believe compression ratio is different, but other than that I haven't really found much besides airbags that may be different.

If someone could point me to the right direction, that would be great.

Edit: found this site which offers a great technical comparison: https://www.automobile-catalog.com/m...-951/1986.html

Still looking for a comparison of the body/lights/options/... and whethere these engines/pistons can handle increased power.
