Ok, i was wondering around what horsepower you should think about upgrading injectors...or if its even needed at all? Im gonna be putting down 235 to the wheels hopefully and im gonna be on stock b18a1 injectors/hondata...anyone have some input?

 

i have heard that you can use h22 injectors but not sure how much bigger they are than your stock ones.

 

idealy you want to be at 80% duty cylce on injectors. with 178ishwhp on rc310cc injectors i was at 79% duty cycle at WOT

you will run way too lean and have bad spray patters if you are running the injector to hard.

get some 310s and call it a day

austin with his 190whp setup is running 290cc prelude injectors he is above 90% duty cylce. if he went with other injectors his spray pattern would improve and would probably pick up some midrange power.

 

hmm, ok so get me some 310's or higher? and what about for break in period? you think that my LS ones will be fine?

 

you will most likely run way too lean with anything below 290cc

im not too familiar with break in period

all gsr/itr/ls injectors are the same. they are 240cc

if you are really going to hit 235whp, then you need bigger injectors

 

If you are going to be at 235whp all motor 370's - 440's. Injector spray pattern and not maxing out your injecotrs or "over-working" them is a good thing. I had a friend blow out 310's due to this. Running to much pressure to over comp for lack of injector size. Stockish fuel pressure is good.

 

For all motor under 240hp you can run up to 310cc. on ECU. if you have hondata or anyother engine management 440cc+ is a must.

 

ok, ima be running hondata...so get some 440's?

saturated right?

 

depends if you're running obd0 or 1,2

 

Im running OBD1

 

so they saturated or not? lol...damn this forum moved fast today.

 

OBD1 civics and integras come stock with 240cc high impedance (~11ohm resistance), Saturated injectors.

 

thanks man
