Forgot about the 930, and i guessed it was a 964 by the trailer and knowing that the 993 was released in 1993-94.
Although, you're wrong about the 180SX. That's an american 180SX S13, which can only be a "Chuki", and a S13 will never be a Zenki or Kouki, because both are S14's. If you're reffering to the 180SX Fastback Type-X from 1996, which is a true JDM car (Only sold in Japan), i tell you that those round lights could be an aftermarket part, bought easily at any tuner shop, which was available for the 180SX since Underground 1 and it's a common modification done in 180SX's.
It's the same 180SX they used since then. American 180SX S13 model, but not the pignose.
Edit:
Edit 2: Ok, i've said a lot of poop. Hahaha i thought NFS always used a 180SX model and badges in their previous games, apparently they didn't and made it right, the previous S13 models were badged 240SX, which is the correct name for the S13 US spec, and in this new one, it's badged as 180SX indeed... so, it can be a JDM.
Although, this tailight is really an aftermarket part, as the original late S13 180SX tailight has a red background, instead of smoked.
