Don't forget an exhaust, as the diesel can't run with car converters. Also, it is heavier, so the front will sag a bit more.

You fuel filler neck is for unleaded, the vaor recovery is for gasoline. this will have to be dealt with...

here in pa diesels have no emmissions test, BUT your registraion will show GAS engine, so you will have to talk to the DMV about that.
