Frequently Asked Questions
Which trim levels and body styles are included in this manual?
All 1990-1993 second-generation trim levels are covered: RS, LS, GS, and the performance-oriented GS-R. Both the 3-door hatchback and 4-door sedan body styles are included across chassis codes DA9, DB1, and DB2.
Is this the same manual used for the Honda Integra sold outside the US?
The second-generation Integra was sold internationally as the Honda Integra. The underlying engineering is shared, so this manual’s mechanical and electrical procedures apply to those vehicles as well, though US-spec emissions and trim details are the primary focus.
Does the manual cover the VTEC system on the GS-R in detail?
Yes. The B17A1 DOHC VTEC engine found exclusively in the GS-R receives dedicated coverage, including VTEC solenoid service, oil pressure switch testing, cam profile switching diagnosis, and timing belt replacement specific to that engine.
What format is the manual?
The manual is a PDF file compatible with Windows, Mac, Linux, Android, and iOS devices including tablets and smartphones. It features searchable text, bookmarks, and high-resolution diagrams for easy navigation in the shop or at home.
