hey hondata has came out with k100 which is about half the price of kpro. kpro go for about $1000 and k100 about $500. kpro you can tune yourself and k100 only a certified tuner can gain access. they release k100 because people were blowing up motorss. you will have to go with larger injectors sense you can't control the fuel pressure with fmu/fuel pressure regulator since you don't have a fuel return line. check out cybernation they have great kit for the rsx which put out the most power that i have seen. 10psi is questionable but i think you can with proper tuning.
