I'm planning on a fuel rail upgrade and was wondering what size injectors I'm going to put on it....??? My H22a1 Vtec has just about all the bolt ons there is w/Vafc. Also planning to stay N/A...

Will also get a FPR & Pressure gauge.

 

H22a1 motors are actually 340cc injectors. The a4s are 290cc. For all motor applications most people use 310cc. For all motor you dont want to go any higher then 440cc, and thats if you run a fully blown race engine. I think your stock ones should be fine for your application.

 

Thanks for the info Gude...!

 

arent only the jdm injectors 340cc? arent the usdm 310cc??? we're talkin 4gen only of course

 

nope, all are 345cc's. How else would you be able to switch between usdm and jdm ecu's?

 

I have RC 370cc injectors for N/A...that's more than enough.

 

i agree. damn duty cycle..

 

before you get too cocky....

my buddy tried my jdm ecu in his car and his car wouldnt stay on. it shut off during his burnout and at the end of the track.
