Z31 Japanese Domestic Market Registry

Nissan sold many Z31 models in Japan that never came to the US: the 300ZR, the 200ZR-I and 200ZR-II, the 200ZG and more. This registry collects the ones that have been imported. Owners add their car through their XenonZcar forum garage, an admin checks it, and the owner keeps the details and photos up to date.

Japanese-market cars have a frame number instead of a 17-character VIN, like HZ31-012345 or PGZ31-012345. It’s on the model plate under the bonnet and stamped into the firewall. See the JDM model differences for what each model came with.

JDM Internal Model Plate Arrangement

This plate is under the bonnet. The model code on it decodes like this:

Position #12345678
CodeKPGZ31JATB
  1. Blank = standard roof (slicktop); K = T-top
  2. Blank = VG20ET engine; P = RB20DET engine; H = VG30ET engine; R = VG30DE engine
  3. Blank = 2-seater; G = 2+2 seater
  4. Model of car: Z31
  5. Blank = Z (200Z) and 200ZR-I; J = ZS and 200ZR-II; X = ZG, 300ZR and 300ZX
  6. Blank = 5-speed manual; A = automatic
  7. Blank = non-turbo; T = turbo
  8. Options: B = power steering; C = manual A/C; G = automatic climate control; H = 4-wheel ABS; L = Recaro seats; R = door mirrors; W = power seats; Z = cold-area specification
Sample decode: T-top, RB20DET, 2+2, ZS / 200ZR-II grade, automatic, turbo, then the option letters (power steering, …)

JDM Z31 Registry Search

Search by any mix of frame number (or part of one), model code, build month, colors, options, condition and owner. Nissan’s Japanese parts catalog lists 11,396 Z31 frame numbers (1983–89); not every car is listed, so a frame number that isn’t found can still be genuine. Owner names and places match only owners who chose to show them.

Is one of these cars yours?

Owner details are kept up to date from your XenonZcar forum garage. Log in, claim your car once (only one member can hold each car, so nobody else can change your car’s record), and then you can update the owner name, location, condition, mileage, website link, comments and photos any time. Your name and location show publicly only if you choose; otherwise only XenonZcar admins see them. Your car also shows on your forum profile.

  1. Log in to the XenonZcar forum (or join; it’s free).
  2. Open My garage, pick Z31 JDM Fairlady Z under “Which Z?” and enter the frame number from the plate in the engine bay, e.g. HZ31-012345.
  3. If the car is already in the registry and no other member has it, it goes straight into your garage with the details you entered. Otherwise an admin confirms the claim, usually within a day or two. Sold the car? Transfer it to the buyer from your garage and it stays in the car’s history.
