TL;DR
Aaron Bonk's Honda K-Series Engine Swaps (CarTech / SA Design) is the canonical K-swap reference. Covers K20A2/A3, K20Z, K24A1/A4 into EG/EK Civics, DC2/DC5 Integras, and CRX chassis. Wiring harnesses, mount kits, axle compatibility, ECU options, fuel system upgrades, and the 100 small details that separate a clean K-swap from one that haunts the owner for years. At ~$30 it's a fraction of one wrong-turn troubleshooting bill.
Why It Matters
The Honda K-series engine swap is one of the most-popular performance modifications in the JDM scene. The K20 makes substantially more power than the original B-series in EG/EK Civics or even the H22 in many Preludes — and the swap has been refined over two decades into a relatively well-documented procedure. Documented well enough that there's now a canonical book on it. This is that book.

Who It's For
DIY mechanics planning K-swaps into 1992-2005 Civic, Integra, or CRX chassis. Anyone tired of piecing together forum threads. Restoration shops. Skip it if you're K-swapping into a Toyota or non-Honda chassis (different challenges), if you're swapping into newer Civics (this is for older platforms), or if you're paying a shop and don't want to learn the details.
How to Use It
Read cover-to-cover before ordering parts. Bookmark the mount kit comparison and wiring chapters first. Cross-reference with current forum threads (HondaTech, Honda-Tech, K-Series.com) for any discontinued part substitutions. Keep it in the garage during the actual swap; photo references save time.
How It Compares
Vs. forum threads (HondaTech, K-Series.com): forums have edge-case wisdom but are scattered. Book is consolidated. Vs. How to Build Honda Horsepower (Bonk): different focus — that's for power building; this is for swap mechanics. Vs. shop manuals (Helms): Helms covers stock service, not swaps.
Bottom Line
The right reference for DIY K-swaps into older Honda chassis. Buy it before ordering parts. Skip it if you're paying a shop or swapping non-Honda platforms.
