Beta Isuzu RZ4E 1.9L Diesel for H-Series ( Van ) 2.1

Minor update for the weakest engine.
-Changed Engine Sound to ETK Diesel.
-Adjusted Automatic Transmission gear ratio to match the Engine Power.
-I recommend using 4.44 gear ratio or higher (Race Adjustable). Good for mods like Adjustable Weight Loads.

-First upload wasn't working because of double folder in zip.
-Added 5 speed AT
-Fuel Tank changed from Gasoline to Diesel
-Added a little smoke
-Renamed from Ibishu 2.2L to 1.9L Isuzu RZ4E
