    First, I would beat your friend up.

    Then, I would talk to PEI330ci.

    Don't see why you can't just upgrade your tranny, it's a manual right?

    Why can't you just upgrade your clutch?

    I don't see why you can't upgrade it, when you can upgrade your penis you can upgrade anything!

    I've never felt the need to research it. No shame Sorena, glad you can speak about it.

    the e36 m3 tranny will bolt up to the 323i block (its also the same tranny as the e46/e36 328i and early 330i) however the driveshaft length is different. you would need to replace tranny and driveshaft, or atleast the front section of the driveshaft and have it rebalanced, or have yours modified. Also the 328i driveshaft from 99-00 is the only direct bolt up, the 330i driveshafts have a cv instead of a u joint where the diff bolts to. you would either have to swap the flange on the diff, or swap the back part of the DS and have it rebalanced *Im pretty sure the DS are balanced as a whole unit, but they might be individually balanced*

    I am using a stage four segmented kevlar clutch master 4 puck sprung with a non lightweight steel flywheel, I believe it is rated for over 600 rwtq. What are you using?

    I have nothing (well brand new OEM m3 clutch) for the power I plan to make. any thoughts on the hpf clutches? they rate them pretty high for what it visually looks like.

    this should totally be moved back to m54. This engine is only not a m54 by throttle body and electronics. Compared to what it has in common with an m54, it is not an m52 at all. Though it is totally an m52 and m54s should then be moved into this category, because they have a hell of a lot in common.

    Let me do some breaking down of the differences between this engine and the other motors in this section
    jacobs323i motor:
    aluminum (identical to m54)
    reverse cooling, cools the head first (identical to m54)
    double vanos (identical to m54)
    89.6mm stroke (identical to m54)
    exhaust port start life as square (identical to m54)
    mls hg (stock) (identical to m54)
    cathedral intake port (identical to m54)
    dual plane intake manifold with electric switch (identical to m54)

    m52 US:
    iron
    water flows through the block first
    single vanos
    84mm stroke
    oval exhaust ports
    paper hg (Stock)
    oval intake port
    single plane intake manifold


    then there's the big disconnect.... jacobs323i has a cable throttle instead of DBW throttle, that is the only difference between it and a m54.


    sorry for the OT, but it was germaine to the top of the thread.
    I agree HPF clutches work great, I've driven on them before and they feel great. I even ran a southbend in my car briefly and did enjoy it. Having said that, my fx850 is the best clutch i've ever driven on, though i don't know how long it will last.

    M52tu=m54 it's the same motor in almost every way.
    As far as being cable driven not really. It uses the cable to actuate the potentiometer to tell the dme to open/close the throttle. So basically m52tu has remote pot and m54 has pot on the pedal. You can even convert your m52tu to m54 setup pretty easily.

    The fx850 is baller and would be my first choice, however it's almost double the price of the hpf

    Would the best solution not be to add an M52TU prefix to the M54/S54 section?
