VW Rabbit TDI Swap

Volkswagen Rabbit

A non-running $1,000 gas-engine Rabbit, found through a Marketplace listing from an elderly couple, given a full TDI diesel swap and a manual transmission conversion.

How it was found

Bought for $1,000 as a gas car that wasn't running — little rust, but dead. The photos from the day it came home show it exactly that way: hood up in the garage, dust on the paint, and a Haynes manual already open on the driver's seat.

The swap

A TDI diesel engine came from a donor Rabbit sourced a few months later. The swap needed real fabrication, not a drop-in: custom motor mounts, a wiring harness, and mounting plates, sourced through S&P Automotive (Sal Robertson), who was generous with time and expertise throughout. The original automatic was converted to manual, along with upgraded headlights and refreshed interior seals.

Still going

It's treated as finished here, though real work continues — most recently a full rewiring after discovering that solid-core wire, bought without reading the spec on the box, doesn't survive diesel vibration the way stranded does. The squeaky original heater can assembly came out during the same pass, and a lot of leftover unused electronics got cleared out along the way.

Lessons learned

  • Read the spec on wire before running it near a diesel. Solid-core wire and diesel vibration don't mix — it eventually fails where stranded wire wouldn't.
  • A TDI swap isn't a drop-in. Custom motor mounts, a wiring harness, and mounting plates were all necessary, and having an experienced resource like S&P Automotive made the difference.
  • Small annoyances are worth fixing while everything's already apart. The heater can assembly's squeak got resolved during the rewiring pass rather than tolerated indefinitely.
