E9x B58 Swap Bible
E90 / E91 / E92 / E93 · 2005–2013 — 179 pages · 56 method pages · 104 build and field records
E9x B58 Swap Bible is a 179-page digital planning reference for a B48/B58 + ZF 8HP conversion into the E9x platform. It is scoped to E90 / E91 / E92 / E93 · 2005–2013, keeps each body branch's evidence separate, and states exactly what it covers — no universal fitment, no guaranteed-start promise, no invented torque or wiring claims.
What's inside
The flagship B48/B58 + ZF 8HP planning reference: donor identity, controller-first decisions, measurement, systems architecture, commissioning, fault isolation, and the full build-record system.
Identity cards, measurements, retained-function contracts, commissioning, and permanent as-built records — print-first worksheets with traceability fields.
Every customer-facing statement is separated into documented evidence vs. the questions your exact build still has to answer.

Questions buyers ask
It states the E90 sedan, E91 wagon, E92 coupe, and E93 convertible boundaries explicitly and keeps the evidence for each body branch separate. A sedan result is not automatically a Touring or convertible answer.
