injector sizing for a high comp nitrous b18
the setup:
81.5mm b18
stock stroke
~12.2:1 static CR
cams
manifolds
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

Re: injector sizing for a high comp nitrous b18 (boostedcivicsir)
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
