\*\* Please fill in all the fields before creating the thread \*\* **Asking Price** : $ (OBO) **Condition** : New/Used **Location** : mississauga **Will Ship?** : Y **Contact Info** : Send PM. **Description** : I have 2 sets of injectors to get rid of. Both are from a dsm, I believe the SR guys use them. One set is the stock 450cc’s in mint condition. no cracks. They came of a Jdm motor with low mileage. …Best offer… The next set are RC 550cc’s slightly more used than the 450’s. No cracks. …Best offer… Pm for more info. ---

If these are DSM injectors They are Top feeds… So they would require a new fuel rail as well correct? as Sr and Ka and most Rbs are side feeds. ---

Im not quite sure… Whoever is interested in them can do the research to find the answer. Or if someone knows for a fact that can state whether this is true or not. Thanks ---

I use to have a DSM and now a SR, Spoolin is right , DSM use top feed injectors ( low impedance ), SR use side feed injectors ( high impedance ) , You will need a new top feed fuel rail , injectors clip connector and also a resistor pack to make it work on the SR. Doing the conversion is totally worth it because top feed injectors are 1/2 the cost of side feeded injectors. ---

Ok guys, I need these gone. $180 for the 550’s $40 for the 450’s ---

Hey dude, to clarify: SR20, KA24 ARE side feeds, as for the RB-series, only RB25DET uses side-feed high impedance 370cc injectors, the RB20DET uses top feed high impedance 270cc injectors while the RB26DETT uses low impedance 440cc injectors. It is said that the RB20 can accommodate the RB26 low impedance injectors with the use of the RB26 injector resistor pack. I have also heard that the RB25DET side feed injectors are interchangeable with the SR20DET. Hope this helps.
