    Lex AFM + 440s??

    Howdy All,

    Long time reader, first time thread starter-upper.

    Background:

    I recently purchased a Lex AFM + 550s from someone on another forum. It turns out the 550s are bad.

    Questions:

    Can I get away with using the Lex AFM w/ my stock 440s to yield increased power so long as it's tuned correctly with my SAFCII?

    or

    Should I stay with stock AFM and stock 440s until I can get the 550s rebuilt by RCEng?

    Thanks in advance for your help.

    (PS. I searched to no avail on the subject.)

    I would get them cleaned and flow tested before going too crazy. But I think there are lots of people that have done it.

    Right on. John's a really cool guy. I bought my K&N kit from him.

    So, now I'm wondering if I'd need to upgrade my fuel pump like he did to get enough fuel out of the 440s?

    I should let it be known that my goal is a reliable/modest 300 rwhp. I'm not trying to break records or anything.

    Mod list so far:

    SAFCII
    Profec B
    K&N FIPK
    2.5" to 3" Megan Racing dp
    3" HK$ catback w/ gutted cat
    HK$ MHG tq'd to 80 ft-lbs
    A342 (1JZ) a/t tranny

    Thanks again for your help!

    Yes, get a larger fuel pump, an AFPR and get rid of the "J-tube".
