Project goal

Evaluate what it would actually take to fit a marine 5.9L Cummins into a Mazda pickup platform without pretending the packaging, cooling, frame, transmission, and weight problems are minor.

Current focus

Start with fitment measurements, engine weight, mount strategy, cooling package, transmission choice, axle strength, brake capacity, and required frame work.

Next notes to add

Add donor specs, engine dimensions, transmission options, mount sketches, estimated front axle load, cooling requirements, and a staged build checklist.
