    I have a b20b with b16 vtec head and 12 cr. I will be dynotuning with hondata so do I still need to upgrade injectors or can hondata compensate for it? I was planning on using stock injectors? Is it really necessary? I have ctr valvetrain and revving to only 8k. I am using walbro 255lph and aem fpr and fuel rail

    theres a good chance you might run out of fuel up top-- just watch the a/f towards 6k and up.

    i'd go with 370's personally....

    How hard are they to take out and put in. I am basically worrying about emissions and dmv and having to swap things out and in. For now all i have to worry about is a test pipe and ecu.

    You can do it if you crank up the fuel pressure some- mine ran on 240s for a good while.

    Yup, good enough- same power curves and same a/f ratios as when I switched to 310cc injectors.
