before you fund it.

The B58 Swap Bible is a digital planning reference and build-record system for BMW B48/B58 + ZF 8HP engine swaps. Each chassis edition (E9x, E30, E36, E38, E39, E53, E60/E61, E82/E88, E85/E86) is a 179–183 page workbook scoped to one chassis family: donor and transmission identity, controller-first decisions, measurement, wiring architecture, commissioning, and the real 2026 cost bands — with print-first worksheets you keep as your as-built record.

Most B48/B58 + ZF 8HP projects stall on unknowns that were knowable — donor identity, transmission variant, controller path, retained functions. Each guide is a planning reference with an evidence register and a record system, scoped to one chassis family. Fully renovated site. Same Bible.

Questions from the counter.

THE SIX QUESTIONS EVERY BUYER ASKS — ANSWERED IN ADVANCE
What exactly do I get when I buy?
An instant, secure download of the full PDF guide or planner — the same day you buy it. No account required to receive it; your download link arrives by email and on the confirmation page.
Is this a wiring harness or physical parts?
No. Every product is a digital planning reference and record system. Nothing physical ships. The guides tell you what to buy, where it goes, and how to verify it — before you spend parts money.
Do the guides guarantee my swap will start?
No guide can guarantee an outcome on a project car. What they do is eliminate the known unknowns — donor identity, controller path, measurement, commissioning order — and give you a record system so nothing gets lost.
What if the guide gets updated?
Owners of record receive every dated revision and errata sheet at no extra cost, for the life of the product.
What's the refund policy?
Digital products are refunded within 14 days when the file has not been downloaded, or when we cannot deliver what was promised. Full terms on the Refunds page.
The website looks completely different — did the product change?
No. The renovation is the building, not the Bible. Same guides, same prices, same instant downloads, same support line. Your previous downloads and entitlements carried over untouched.
DEPARTMENT 03¾ · CURRENT PRODUCT TRANSPARENCY

Built on facts, not hype.

NO INFLATED NUMBERS · NO BORROWED REVIEWS · JUST WHAT THE FILES ACTUALLY CONTAIN
Evidence-controlled release

Every guide separates OEM facts, controller documentation, specialist practice, documented field evidence, estimates, and recommendations — instead of presenting every claim as universal.

Dated revisions & errata

Updates are traceable: revision date, changed sections, source review, known limitations. The release policy is published with each edition, not implied.

Real product boundaries

Available guides state their page count, evidence base, and limits. Future chassis stay visible on the bench without pretending discovery is proof.

Built around real swap risk

Structured around the problems that stop real swaps: physical interfaces, wiring and CAN, controller support, first-start faults, adaptation, heat, driveline, safety validation.

FUTURE CHASSIS REMAIN EVIDENCE-GATED DATED REVISIONS AND ERRATA REQUIRED RECORDS STAY WITH THE CAR

The E30 program ships

The 183-page customer edition left the bench this week: the original vector visual appendix, 177 bookmarks and build records, and exact-configuration verification for every E30 body style. The boxy classic, planned like a factory program — because that's what it is.

✓Scope locked to E30 body styles
✓Exact-configuration verification

WHY IT MATTERS

Most E30 swap threads end at "where does the harness go." This file starts two steps earlier: is your exact car an achievable project, verified before parts money moves. That's the difference between a plan and a wish.

DEPARTMENT 04 · RENOVATION NOTICE · READ THIS FIRST

Everything's been redone.
Nothing's been replaced.

If you've been here before, you'll notice the whole workshop has been rebuilt — the site, the catalog, the brand, the layout, all of it done over. So here it is in writing, before you wonder: the B58 Swap Bible is the same product you know. The renovation is the building, not the Bible.

What changed

  • The entire website — rebuilt from the studs up: new store, new cover, new departments, new navigation.
  • The brand, redrawn — new logotype, M-livery stripes, plate numbering on every file this season.
  • Field Notes — shop dispatches now publish as signed work orders, with your builds on file.
  • Magazine structure — the store reads like an issue: cover story, contents, departments, colophon.

What didn't

  • The guides — same content, same revisions: E9x R1 · E30 R7 · E36 R1 · E46 R1 · E39 R7 · E38 R7 · E53/E60/E82/E85 R7.
  • The prices — $97 guides · $37 planner · $117 crew bundle. Unchanged.
  • Instant secure download after Stripe checkout, exactly as before.
  • The revision policy — owners of record receive every new issue and errata sheet.
  • The support line — same inbox, same person, same answers.
Bought before the renovation?

Your download links, revisions, and entitlements carried over untouched. Nothing in your garage changed but the lighting — same garage, new lighting.
