Hi I’m currently building a turbo setup on my 91 and am wondering on people’s thoughts and comments of Injector Dynamics (Bosch) 725cc High Impedance injectors? am i better with lower cc or higher cc? or low impedance? also what about the resistor box? thanks!
I went with those exact injectors with my build, and based on what i’ve read, they’d be great for a mild street build, with room to grow(up to 500+) but it would really depend on what your setup was as a whole, what your hp goals are now, and where you want to eventually be.
i’ll go ahead and give you my specs so you have somthing to compare to:
stock block(non-vtec)/arp headstuds
walboro 255(hp)pump
aeromotive filter/fpr
injector dynamics 725cc
golden eagle fuel rail
garrett t3/t4 57 trim .63 a/r 360 degree thrust bearing turbo
full-race ramhorn manifold
tial bov/waste gate
full-race intercooler
hondata s300 management
horsepower goal is 275, injectors SHOULD power up to 500:rockon:
and as far as the resistor box, just needs to be unplugged, although some ppl
cut the wires and tape them together?:werd:
i have no road testing on these injectors yet, as i am waiting to be tuned, but i will post #'s up when they become avail.
Btw, i purchased the 725’s from xenocron, cool ppl over there!
thanks for the reply! and yes i think I’m going to go with them, they seem like a good bargain. I’m ordering them from xenocron. I called them and he said if i don’t plan to go over 500 hp, which i don’t, then they will be perfect, he said they have a nice spray pattern and can spray little enough to idle properly 14.7afr-leaner if desired, where as 1000cc + will give you a rich/rougher idle, I’m ordering them right now 
gotta get this build off the ground!!
also i’m on a fully built sleeved block, so when i get it all together i’m going to post some numbers!! 400whp goal 
Sweeeet, glad that helped, and good luck on your build as well:rockon: 400hp is very realistic for a built/ sleeved block, i’ll be keeping an eye out for this beast!:burnout:
