i have a h23 prelude got some dsm 450cc injectors what will i need to run them with. i am running 7-8 psi

 

fpr, and or s-afc/vafc

 

you cant just run 450's and a fpr. you gotta get a vafc or a standalone to run that. no stock honda ecu can idle 450s.

 

resistor box and an afc.

 

my car runs perfectly smooth with 450's and an adjustable fpr. that's all. It is certainly runnin a bit rich, but really isn't too bad. just to share.

 

Do you have a pressure guage? What regulator do you have? Just curious what your fuel pressure is and how you got it that low.

 

any more info on this?

So I guess just a plain FMU ain't going to help run 450cc's

 

ran mine that way to, 31psi, ran like a champ...idle was a lil rough....a lil, but once the gas pedal was on it ran fine

 

To tell the truth...my crappy NOS fuel gauge never worked right, so I took it off, since the face filled up with fuel...anyway, I'm using a Command-flo regulator, so it only goes down to 25psi and that's what I'm at. I was running it one turn it, which should be 30-35psi, but after driving that for a week, I noticed my bumper was gettin a might grubby from running a little rich (as the A/F meter said).
