DB2 or DB4

I have never seen a DB4 pump. Why do these pumps not fit out engines? Are the mounting surfaces not compatable? The pump to large or to long to fit in the same position as the DB2? The input shaft will not mount to the drive gear? Will it change the length of the injection lines?

you should understand,that much fuel for a stock turbo (normal aftermarket turbos) idi would also be pointless.

True enough, but the same place that does the pumps also do turbo upgrades.

^^^ this... Also I did forget to mention what ForF250HDXLT said. An upgraded turbo is essential when running a Db4. If it is a stock turbo, go with a turbo-cal.
