Motor Swap Atlas hero

What to expect

Built around honest planning, not magic compatibility claims.

01

Traceable research

Keep source notes beside the decisions they support.

02

Clear uncertainty

Flag measurements and assumptions that still need verification.

03

Builder-owned plans

Export and share your project details without locking up your work.

A working atlas

From a promising combination to a buildable plan.

Organize the whole swap around dependencies—not a generic shopping list. Every choice stays connected to the project it affects.

01

Search the swap landscape

Start with the chassis and engine you have in mind, then narrow the field with structured compatibility notes.

02

Build a defensible parts plan

Keep mounts, transmissions, oil pans, wiring, cooling, fuel, exhaust, and supporting hardware in one working list.

03

Track decisions and unknowns

Record fitment choices, open questions, sources, and budget assumptions before they turn into expensive rework.

04

Share one project brief

Give collaborators and shops a readable plan instead of asking them to reconstruct decisions from scattered messages.

Straightforward access

Choose the depth your project needs.

Explore for free, then upgrade when you need multiple builds, richer planning, or collaboration.
