TB
stock port

should be good for 210-215 on engine

looking to make 300+ on nitrous....the car will have seperate tunes for NA and nitrous but id like injectors that can work for both applications...any advice would be appreciated.thanks

 

will 440cc be sufficient for my power goal and still give me room for more power?

 

440's should do it, but room to grow? i personally like 550's. and there should be room to grow.

 

would large injectors such as 550's take a lot of tuning time to get right when running NA? i would imagine the fuel pressure would have to be turned down substantially or the pulse time would have to be reduced dramatically? does this seem correct?

 

It shouldn't be that big of deal for a tuner to tune. I'm running 550s on my turbo set up, and when I'm not boosting I'm still just fine. I'm not a pro, but I think it's an easy thing to tune for.

Arent you obd0? Im sure you will be coverting to obd1 but if you have the resistor box installed you might want to think about some DSM 450's. They are cheap and are oem injectors and have very few problems. They work good for me

unfortunately my EF is no longer with me , i got a 95 civic coupe that im messing around with right now, so im obd1...

do they make stock obd1 dsm injectors?

is there another formula for finding injector size that does not utilize the engines CFM rate

 

yes they make obd1 dsm injectors.
