dsm injectors are top feed. You need a top feed fuel rail. projectsilvia's rail will work. I have one and it lookes great. If you run it just get a adjustable fpr. To hard to install your factory one on the top feed rail. Also you need a resistor box or some resistors. dsm injectors are low impedance where as your ka injectors are high impedance. You just wire them in on the power wire for each injector. These can be found in junkyards in hondas and eclipses. Or you can spend 20 bucks and get a set from jgs tools.

gto there and scroll down to the gold resistors. Just solder one one the power wire of each injector and your set.
Also try checking the big sticky on the top of the ka-t section labeled "IMPORTANT INFO READ FIRST" and it has a injector spread sheet there.
Later man!
