Donna the Datsun — 280Z Build

Donna, a metallic blue Datsun Z with a roll cage visible through the windshield, hood vents and a wide front air dam, parked on a driveway.

It started in 2017 with a $1,500 1977 Datsun 280Z and a pile of problems — corrosion, hidden crash damage, and all the charm of nearly fifty years of neglect. But the vision was clear from day one: build a track car that my dad and I could drive together and go fast.

We tore Donna down to bare metal. I repaired the chassis and rebuilt the entire rear floor section. Every bit of undercoating was stripped. From there, we designed and hand-fabricated a full roll cage from scratch — every tube hand-mitered and coped, no kit, no templates.

After almost ten years of work, every piece of Donna is purpose-built and custom. She looks mean, she's mechanically serious, and we're now deep into the final mechanical assembly stage.

What I did

Everything. This is a father-son build with no corporate safety net — just problem-solving with our own hands.
