i was planning to run some dsm 450cc in my gsr-t set up. does it matter what resister box i use? can i use my stock o rings to put around the dsm injectors or i have no choice but to cut back the dsm o rings and make a fit?? can an amature do this without problems??

 

you need a total of 12-13 ohms of resistence through the circuit. so if your injectors are 2-3 ohms, you need another 10 ohms of resistence. i know if you are using separate radio shack resistors, you need 10watt 10ohm resistors.
