They don't need to be limited to ~64, they could have 200 with a litre bike engine and a hybrid motor for reverse and launch They would probably have just that if demand was there
The Carrozzeria head unit was made by Pioneer. As far as i know its only for Japan and more high end stuff. The units can be connected so an older Tape one can use a second one with CD or MD. Got an MD unit + spectrum analyzer for my vintage Mitsubishi.
Not much to deduce from the "Carrozzeria" head unit unfortunately. That's as good as saying "Sony" or "Hitachi" on it. Because they made a bazillion factory and after market head units for cars both. In the 90s, many JDM cars also blatantly came with otherwise "aftermarket" options as stock, so it's really a wash trying to figure it out. Even ones that look insanely out of place can be stock.
