Japanese Super Car Ratios (NA to Turbo)

Every time I see a post about "why is the 3S so cheap compared to..." the same answers come up. The 3000GT/Stealth was produced in much greater numbers then any other of the so called 90's Japanese Supercars. Also the ratio of non-turbo cars to turbo cars was much greater then the other cars.

All of these ratios are NA:Turbo. The numbers are from production numbers I found posted on the internet.

• 300ZX (Z32) 3.66:1 (convertibles not included)
  Total Production 300ZX (Z32) 89,156
• Supra MkIV 0.610:1 (there are fewer NAs than Turbos)
  Total Production Supra MkIV 11,239
• 3000GT 4.25:1 (includes Spyders)
  Total Production 3000GT 86,151
• Stealth 4.32:1
  Total Production Stealth 65,303
• Stealth and 3000GT (combined) 4.27:1
  Total 3S combined 151,454
• Total Production RX7 FD3S 13,879 (All turbo)
