I have some 720 injectors right now and was wondering if they were too big for a street car. I was planning on running 12-14lbs on the street and probably 18 at most on the track. This is mostly a street car. I also have an ems standalone and wideband o2 sitting around, but was waiting on the injectors. Thanks

 

anyone?

 

you can idle the 720cc with hondata fine as well as most standalones. You can push around 480-500hp with that size injector at around 80psi max pressure or

 

well, 440s max out around 12psi, and I'm sure 550s would max out by 16-18ish.

If you can get it to idle on 720cc, should not be a problem.

I have 550cc and AEM ems, and my idle is alright, but no like stock. I hear
alot of people have problems idling larger injectors on Hondas on EMS.

I've also heard that Hondata idles large injectors like stock..

so what would u guys recommend?

 

550cc should do the trick or 650cc

 

i use 720cc and drive the car on the street all the time.

 

what are you boosting at on the street and at race?

 

15 psi on pump gas and 25 on race gas.i already get no traction at 15psi so any higher would do no good

 

Yup! Hondata and large injectors idle like stock.

 

so do the 720s eat gas like no other? So what about fuel economy, which would be better?

 

i get almost 20 mpg

 

Hey guys, I need some help here. I bought a set of DSM injectors off 90 Talon non turbo. The guy didn't know how they rated. So can you help me?
On the injectors they have the words: 89X, below that INP-053. On the other side: B240H. Thanks
Oh yeah, how do I know if they will work? Is there anyway to test them?

 

i dont think talon non turbos are gonna be much bigger than your stock ones. maybe if its the 2.0 version ? but still i dont think they will be much use to you, i could be wrong though.

 

those are lke 320 or something.

 

Sorry, those non-turbo DSM are 240cc. Same as your stock ones.

Turbo DSM autos had 320's and turbo DSM manuals had 450's.

How do you know when your injectors are maxed out or what duty cycle they are at? I have an h22a running a 50 shot and will go up to a 100 shot NX this summer. Currently no fuel mods, but have the B&M fpr and guage and walbro 255lph pump ready to go in. When do I know to change injectors? How big? Hell I dont even know what size i have now.

 

oh screw it im just gonna drop in a 3SGTE into my Integra, i bet it would still be cheaper than turboing the B block and trying to get it to run perfect lol

btw im just kidding before anyone starts flaming me
