like general people, or toyota supra enthusiasts ?
Since you opened up that can of worms...I identify as a heritage edition. I was born a BMW but mentally I've always felt I was a supra heritage edition.
Flyin Miata does something along these lines for their conversions of ND Miatas with LS3 setups. Hot Rod did a whole article on it to showcase what modern tinkering was like at a high end level.A true "conversion kit" would address this issue with a canbus module that works on 2jz electronics.
