I cant decide what size of injectors to get. I am looking for 300whp out of my GSR on a stock B18C1. I will be using a Garrett t3/t4.

I know the RC 550 saturated injectors will get me to my goal, but later I plan on building the engine and am looking for 400+ whp. Should I go with 750's now so i don't have to upgrade later? Will the 750's have any negative effects if I run them to only support 300whp?

they are only ten dollars more here.

Also, what cars do the plug and play injector clips work with? I will have to put my OEM injectors back in for emissions hopefully those will ease that process.

Thanks alot

Buy the injectors now for your goals now...bigger injectors will, but I am a big believer in sizing for your goals now, not for the future.

OBD2 plug n play injector clips are for installing aftermarket (RC/Precision) injectors into an OBD2 Honda (1996+)

if i run 750's now what will the problems be? uneven idle, running less smooth at small throttle openings?

I had 1000's on my car my goal was 450whp. I made 470whp on my stock block with big injectors and the car ran fine

I would say get the 750's and a good tune and you should be fine. Its all in the tune.
