THE SHORT ANSWER

E30 Swap Guide is a 183-page digital planning reference for a B48/B58 + ZF 8HP conversion into the E30 platform. It is scoped to E30 3-Series · 1982–1994, 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

Scope

The full E30 customer-edition swap guide: achievable-project path, exact-configuration verification, controller-first integration, measurement and fabrication records, commissioning, and permanent as-built records.

Build-record system

Identity cards, measurements, retained-function contracts, commissioning, and permanent as-built records — print-first worksheets with traceability fields.

Evidence register

Every customer-facing statement is separated into documented evidence vs. the questions your exact build still has to answer.

Questions buyers ask

Is there a universal B48/B58 + 8HP recipe for an E30?

No universal recipe is established by the research record. The exact engine, transmission, controller, body, driveline, and electrical state control the answer — the guide starts from an identity sheet, not a one-size answer.

Does the E30 guide promise my build will fit?

No. It separates documented evidence from the questions your exact build still has to answer, and tells you what to measure before ordering parts.

Is this a physical product?

No. It is a digital planning reference and record system. Nothing physical ships.
