Don't runa ko3, they are the worst turbo that came on any of the turbo diesels, get a turbo of a 1.6 liek the garrett t3 or the kkk24, they are twice the size of your ko3, will make more effecient boost and won;t make so much exhaust backpressure. A modified 1.6 or 1.9td pump is good, just get a core pump and send it to giles at superior fuel injection.
