    I went today to get a JDM LS motor. I wanted a 5speed but forgot to tell them that. I had told them that last week but they probably forgot or I talked to someone different then who I got it from today,honestly I just got in a hurry and had a brainfart. I took the motor to my mechanic who in return calls me tonight and says hey did you know this was a automatic motor. The motor also had a broken TPS and the harnesses were chopped to death. This is a well respected shop so i'm gonna call them tommorow probably won't help though because that stuff 9 out of 10 times is'nt covered..
    How bad is the JDM automatic cams gonna hurt my setup??
    I'm running a t3-t4 60 trim 56intake 60exhaust with a full 3inch DP and exhaust. Its a stock JDM LS motor and will be running 8-9psi..

    I have extra 5 speed cams should I have them put in??
    Should I install my JG cam gears or are they useless??

    Somebody help me...

    Can I just swap the 5spd cams for the auto's with no other valvetrain upgrade??

    never have i heard of an automatic motor. anything ive ever seen or worked on was always the same..... i hope someone clarifys this.

    maybe a sensor or two more on one motor. but no physical difference!

    as far as i know the only difference is the transmission, ecu, and tranny mount.

    [​IMG] the cams are different
    [​IMG] you can replace them with 5 speed ones
    [​IMG] you probably wont notice a differrence witht the auto cams on a boosted setup
