Hi Paul and welcome to the forum.
As kunev said, there is no much activity here, but the information in old post is extremely good (it should be possible to back it up for the time when this forum will be dpwn).
The engine of your "new" Delta is the same of the Alfa 155Q4 that is really popular here. Almost the same for the transmission, so lot of the information here or ansewrs you could get, will let you know better your car.
