Thanks for responding to my response.
The injection pump problems with non hardened barrells will take time to show up.
It is not difficult to find 123 cars without rust in Texas. If the rust ever gets overwhelming, I would be interested in buying the car, and use the drivetrain to build a non rusted, five cylinder, five speed car out of. The non Turbo is fine. There are pluses AND minuses to the turbo.
