This comes to mind
Started as an 1986 Sport. touched every nut and bolt on it. Ported 13b motor. Light weight forged steel racing flywheel and a semi race clutch. Complete turbo suspension with a bunch of JDM racing bits that took for ever to show up. Complete Turbo driveline swap (trans to wheels) including the sub frames. Titanium exhaust. It was a car that the average person would say it was a nice looking car but an enthusiast would look over and really like. The car was originally Mazda gold but I had it completely re painted while I had it down to a shell using GM gold from a 1980s corvette. Small difference in color. Again only a car geek would notice. Interior was stock new OE in burgundy. I then pulled the seats in favor of a set of 85 gslse seats. I did everything with this car from track days to cruze nights to DD to jobs all over the country. I kept upgrading the motors. It got to the point where I could swap a motor by my self in 3 hours.
I really miss that car lightness was the main objective. In final form it was just under 2400 lbs wet.
