first... are ls injectors the same as gsr injectors?

Second.. upgrading the injectors on a all motor application what size is safe with a stock head, i hae a fuel pump, rail and fpr, the pistons are upgraded to ctr 12.1 cr, and i have other bolt-ons! thanks for the posts!

 

ls are a smaller cc then gsr. what cams are you using? w/ 12:1 comp. you should have 270cc-310cc.

 

r u sure they are different? can anyone else verify this? i thought all b-series injectors have the same cc's?

 

i heard all b series injectors are the same.. i was using ls injectors on my b16 in a crx....i had no problems...

 

im pretty sure stock B20 injector are bigger then b18 & b16. i might be wrong.
it really doesn't matter cuz he needs big injectors any how.

ALL of the civic and integra injectors are the same... 240cc.
the only differences are the clip styles per OBD year/style.
there is the possibility of JDM ITR injectors being larger at around 270cc, I cant remember if that got verified or not.

 

i just happen to have a set of RC 310cc's that should work fine for you.

thansk for all the posts pm's answered!

 

ALL the B-series injectors are rated at 240cc. The top of the line single cam VTEC D-series also use 240cc injectors.

For bolt-ons with increased compression, the factory injectors should be OK. Just use an adjustable fuel pressure regulator to fine tune it.
