To check part compatibility and for researching if the rare parts you find can be used in your Civic build, I hope you find the spreadsheet below useful. It has tabs at the bottom for each of the following sections:

  • Engine Serial Numbers
  • Honda Engine Codes & Specs
  • Transmission Chart
  • Chassis Codes
  • 1200 Maintenance Schedule
  • Parts Numbers
  • D Series Head IDs

Back around 2010 I built upon various spreadsheets around the web to collate as much technical detail as I could for the 1st Gen Civic. Many thanks goes to the contributers of 1stgencivic.com/forum.
Please note that the information above may have errors and is far from complete.
