If your interested, I am rebuilding two motors to TD42T standard. One to sell to fund rebuilding the second for my car, so I can pull out my tired motor.
It will be done by Queensland Engineering Service, and rebuilt by Whites Diesels. It will be a long motor, so if you already have a tired motor, just put your other gear on him and go. It won't be run in, so you'll have to follow the run in procedures supplied by Whites.
