How to Rebuild Honda B-Series Engines Book Review

Honda B-series engines (B16A1, B16A2, B18B, B18C, B20B, B20Z) defined the JDM-tuner era of the late 90s and early 2000s. Tens of thousands of these engines have been swapped, rebuilt, and modified by hobbyists. Jason Siu's 'How to Rebuild Honda B-Series Engines' (~$33, 367 ratings, 4.6 stars) is the printed workshop manual that walks you through a complete rebuild from teardown through final assembly.

TL;DR

This is the right book for someone planning their first B-series rebuild. It's structured like a service manual but with hobbyist-friendly explanations: photographs at every step, torque specs called out, component-by-component teardown and reassembly. Doesn't replace a Honda factory service manual for niche specs, but it's the only reference that walks through the rebuild in narrative form. Worth owning.

Why It Matters for JDM Owners

The B-series rebuild is a rite of passage. Whether you're refreshing a 200K-mile B16A2 (probably needs new rings, valve seals, possibly bearings), prepping a B18C5 for forced induction, or building a B20VTEC frankenstein motor (B20B block + B16A head), you need a workshop reference that explains the rebuild logic, not just the torque values.

Factory service manuals (Helms, AllData) tell you the specs. This book tells you the sequence — when to measure, when to replace, when to send to a machinist, what tolerances to actually worry about for street vs race builds.

Key Specs

Author: Jason Siu
Publisher: CarTech (specialty automotive press)
Format: Paperback, ~144 pages
Photos: Heavy photo coverage — most pages have 1-3 process photos
Engines covered: B16A1, B16A2, B16B, B17A, B18A, B18B, B18C, B20B, B20Z
Rebuild scope: Complete teardown, machining specs, reassembly, post-build break-in
Topics: Cylinder head, block, rotating assembly, valvetrain, oiling, timing, tuning basics

Pros

Step-by-step photos throughout. You're rarely guessing what a 'main bearing in cradle' looks like — there's a photo showing it.
Honest about machining requirements. Calls out which tolerances need a machinist (cylinder bore, crank journal grind) vs which a careful DIYer can measure (deck height, ring end gap).
VTEC-specific coverage. The VTEC mechanism is the unique feature of B-series. Book covers it specifically — assembly, lash spec, troubleshooting.
Forced-induction prep notes. Discusses prep specifically for turbo or supercharger applications: ring gaps, bearing clearances, head studs.
Tool list at the front. What you'll actually need vs nice-to-have. Saves money if you're equipping a first-time rebuild.
Affordable. $33 is reasonable for a niche workshop reference.

Cons

Doesn't replace the Honda factory service manual. For niche specs (specific valve clearance for an obscure variant), you still need Helms.
Mostly normally-aspirated focused. Forced induction is covered but not deeply. For a turbo-specific build, supplement with 'Maximum Boost' by Corky Bell.
Photo quality is mixed. Some photos are clear, some are slightly low-resolution prints. Not a major issue but noticeable.
Doesn't cover K-series or D-series. B-series only. Don't buy expecting cross-engine coverage.
Out-of-print editions vary. Some sellers ship older editions; the differences are minor but verify the publication date if it matters.

Who It's For

First-time B-series rebuilders. This is the bench reference that teaches you the rebuild as you do it.
Hobbyist mechanics preparing a B16A2 swap, B18C refresh, or LSVTEC build.
Forced-induction project owners wanting baseline rebuild knowledge before going turbo.
Honda Type R / Si owners who want to understand what their engine is doing internally.
Reference for shop-class builds — instructors and students.
Skip if you're rebuilding a K-series (different book), if you only need OEM service info (use Helms manual), or if you're a professional shop already doing 50 builds a year.

How We Use It

The routine: book stays open on the bench through every B-series rebuild. We follow it as the primary narrative — read the section before tearing down that component, follow the photo sequence, cross-reference with Helms for any spec that matters more.

For a B16A2 refresh in a 1998 Civic Si: pulled the engine, used the book to walk through the crank-journal measurement, ring end-gap check, valve-stem seal replacement. Hit factory specs without trial-and-error — the book pointed out the stuff that matters.

For a buddy's B18C5 prep for a turbo build: book got us 80% of the way; we supplemented with online forums and 'Maximum Boost' for the turbo-specific prep. Combined references gave a complete picture.

How It Compares

vs Honda Factory Service Manual (Helms ~$120-200): Helms is the OEM source for specs. Use both — Helms for specs, Siu for narrative.
vs Building Honda K-Series Engine Performance ($35): Same author/series for K-series. Same quality, different engine.
vs HondaTuningMagazine archives (free online): Online references are scattered. The book's value is consolidated narrative in one place.
vs Honda B-Series Turbo Build Guide (online forums): Online has more turbo-specific content. Book is the foundation; forums are the build-specific reference.

Bottom Line

'How to Rebuild Honda B-Series Engines' by Jason Siu is the right $33 workshop reference for hobbyist B-series rebuilders. It teaches the rebuild sequence with photos at every step — turning a daunting first-time project into a manageable Saturday-morning workflow. For anyone planning a B-series refresh, this book pays for itself the first time it saves a phone call to a confused mechanic.
