I'm done putting my b18b1 together. The typical all motor non-vtec setup. P73-00 pistons, Crower 404's, Crower double springs and retainers. and the typical mods etc...I have stock obd1 b-series injectors. I was told all b-series injectors were 240cc. Should I upgrade? The motor will possible lay down 170 whp, maybe a little less.

 

stock is fine

 

Do the guys runnin 200whp run stock or upgrade?

 

im runnin stock injectors on my motor....

 

that sums it up, thanks bro.

 

310's would be good if u just wanna upgrade.

 

stock injectors are perfectly fine

 

yup stocks would be fine......after 220whp or around ther u should use larger sz injectors for better atomization

 

oh and for the record my itr motor is sitting at 190 witht the stock injectors

 

I am running re-calibrated oem injectors, 250cc/min at 82% with stock fuel pressure. My car makes about 175whp and is tuned with a Hondata S300.

 

ive made 181whp and 192whp on stock injectors....
i have seen as high as 210whp on stock injectors but you are pretty much maxing them out.. also your fuel pressure plays a role as well
