check the silver plate on the firewall. For s13’s 89 - 90 240sx’s come with ka24e and 91- 93 come with ka24de engine the “de” is Dohc (dual overhead cam) and the “e” is sohc (single overhead cam). Sr20det engines are jdm and many swap those into north american 240sx’s. The sr20det was used in the newer gen s13’s and the ca18det was used in the older gen s13’s ---
