My preference would say these aren't REAL Nolstalgics the power plants are anything but Nostalgic but I'm not going to dismiss you and say you shouldn't be here. The cars are old enough and you are certainly passionate about them.
Personal preference is everything sometimes, but really, I would still see those cars as Nostalgics, just either setup for racing or in the case of just general motor swaps, those fall into "RestoMod". Restored with new paint, but components such as suspension and powertrain are changed out in favor of newer, more modern parts, often with the aftermarket support and parts availability in mind vs the now harder to find and NLA parts for some of our cars. Just like there are Hot Rods (Restored and strictly period correct parts) and Street Rods (modified with newer parts, modern components), as long as the body hasn't changed entirely it's still a Nostalgic in my book.
Mitsubishi Garage, we're starting to see an occasional 91-92 Galant VR-4 pop up, but as time goes on, we don't pay much attention to them. They still got sometime before they are really welcomed in (Galant GSXs and Galant VR-4s are rare in the US sure, but that doesn't make them Nostalgic) it really depends upon the model, but also by the 90s most Japanese cars went pretty much FWD for everything and that is more of where I see the cutoff for JNC truly end with the except of the few exceptions for specific models.
