Acura Integra 1993 Service Manual – Factory Torque Specs & Wiring That Work

If you’ve ever tried to rebuild an Integra engine using a generic online PDF, you know the feeling of chasing a bolt with a torque spec that came from someone’s uncle’s garage. That’s how oil leaks start. That’s how you end up with a customer’s car back on the lift three days later. This 1993 Acura Integra Service Manual is the original Honda Motor Co. document – 1413 pages of factory specifications, written by the engineers who designed the car. Not a reprint. Not a third-party summary. The actual binder that dealers used.

Engine Overhaul: Factory Specs You Can Trust

The Engine section (bookmarked section H) covers every disassembly sequence with bolt torques and thread sizes listed on page 3. You get the exact valve adjustment clearance, head bolt tightening pattern, and main bearing cap torque – in lb-ft, not some generic range. If you’re pulling the head on a B18, this manual shows the factory order. Page 3 also has the special tool list for each operation. No guesswork.

Fuel and Emissions System Diagnostics

Section “Fuel and Emissions” includes the full troubleshooting tree for the PGM-FI system. Throttle body adjustments, idle air control valve tests, and O2 sensor voltage ranges – all from the Honda test engineers. The manual gives you resistance values for injectors and TPS at specific temperatures. Aftermarket manuals often transpose those numbers. This one doesn’t.

Does This Manual Cover the SRS System Safely?

Yes – and this is where the aftermarket copies fall apart. The Supplemental Restraint System (SRS) section on page 4 contains the airbag removal procedure, connector lock inspection, and the mandatory battery disconnect step. The manual warns: “Indicates a strong possibility of severe personal injury or loss of life if instructions are not followed.” That’s not a suggestion; it’s a directive. If you’re working on a 1993 Integra with a driver and passenger airbag, you follow this procedure exactly. No shortcuts.

1413 Pages of OEM Documentation – What You Get

The manual is broken into 23 sections (bookmarked with thumb tabs on the back cover). Each section starts with an exploded view index that shows parts disassembly sequence, bolt torques, thread sizes, and page references. The major chapters: Specifications, Maintenance, Engine, Fuel and Emissions, Transaxle, Steering, Brakes (including ITEg), Electrical (including ISBE), SRS. Every torque value, every wiring diagram, every adjustment spec is factory-verified. For the later model electrical diagrams, check the Acura Integra 1998 Service Manual. If you need the electrical section specific for a 1998, the Acura Integra 1998 Service Manual – Section: Electrical (Including Srs) isolates that content. The 1998-2001 Acura Integra Service Manual – Section: Electrical (Including Srs) covers the full range for late-model work.

Audience Fit: Who Needs This Manual

DIY mechanics who want to avoid breaking expensive components. Home garage enthusiasts who need the right torque the first time. Beginners should not touch the SRS system without this manual in front of them. Professional mechanics – you know the cost of chasing a spec that doesn’t exist in a Chilton. This stops that. For industry reference, see Automotive Industry Overview for how OEM documentation sets the standard. Compare that to aftermarket “summaries” that omit critical warnings. The difference is liability.

Source Validity: OEM vs Aftermarket

Printed by Honda Motor Co., Ltd. in July 1993. First edition, 1413 pages. The PDF scan is from the actual dealer binder – not a scanned reprint from a third-party reseller. The table of contents matches exactly with the thumb tabs. Aftermarket manuals often leave out the SRS warnings or transpose wire colors in the Electrical section. This one has the original Honda part numbers and test procedures. If you see a “CAUTION” icon in the margin, it’s from the factory – not added by a copy editor. For broader context on factory documentation, Automotive Industry Overview explains why OEM specs matter.

Frequently Asked Questions

Does this manual include torque specs for the cylinder head?

Yes, page 3 lists the torque sequence and final value in lb-ft.

Is the SRS section complete for a 1993 Integra with passenger airbag?

It covers both driver and front passenger airbags, including the special precautions on page 4. You also get the diagnostic flow chart for the SRS indicator light and the removal procedure for the steering wheel hub.

Can I use this manual for a 1994 Integra?

This manual is specifically for the 1993 model year. While many components carry over, wiring changes and calibration updates occurred. For a 1994, the Acura Integra 1998 Service Manual is the correct document – note that the 1998 manual covers the third-generation body style, so verify compatibility.

What format is the manual?

Digital PDF. Searchable, printable. Same pagination as the paper original.

You’ve seen what happens when a torque spec is off by 5 lb-ft on an aluminum head. You’ve watched someone chase an electrical gremlin because the aftermarket wiring diagram had two pins swapped. This manual eliminates those variables. It’s the blueprint. Access the Factory Manual now and get the 1413 pages of specifications that Honda trusted their technicians to use.
