EFI to Diesel conversion.

The ZD30 air box will do you for now, It depends on what turbo you go for & how much air flow you will need. I went for the UFI 18g turbo low mount with DC6 pump & cross country intercooler with 3" mandrel bent Exhurst. I went for the TD42 silver top engine with GU turbo head. You will need a pump with the boost compensator valve on the top also if going turbo.

Not particularly. If he runs a very mild setup like the DTS or a ht18 he can easily get away with the NA pump. It will be a benefit yes if he feels he can afford it it ends up with a compensated pump.

Your setup is a little more expensive than what bloodyaussie is chasing.
