    What's up guys! I'm new to this forum, but not the subject, so don't worry about me asking any stupid newbie questions. So here goes...

    I'm considering buying a D15b vtec and I'd like to have the ZC tranny with the LSD, but I read somewhere that the ZC tranny has to modified to bolt up to a 1.5 liter motor. Is this true?

    Pretty sure it will bolt right on, since they are both D series family motor/tranny's. And you may want to remove the pic from the sig, it's policy. :)

    it will bolt up - the ZC transmission uses an intermediate shaft and you will need to use 90-93 integra axles

    I always wondered about this. Is there any reason you can't use standard d-series axles with a ZC tranny? (not that you would want to with a ZC LSD tranny)The transmission case is identical to every other D-series tranny, right?

    Or for that matter, what would prevent someone from using the ZC axle setup on any other D-series tranny(e.g., Si)?

    Also, good luck finding and OEM ZC tranny with LSD. They are extremely hard to find.

    It depends on whether or not it is a SOHC, or a DOHC. If it is DOHC you can't because those like the B's use a halfshaft, if it is SOHC, then it is like the other D family, and can use the D axles.

    Answered my own question by doing a little research. You CAN use USDM d-series axles with a ZC tranny. Granted, the torque steer will be worse, but it is possible to use the long/short axle arrangement on a ZC tranny, DOHC or not. Until anybody can prove otherwise with first-hand experience, I'll assume the mod at the ZCresource knows what he's talking about:

    EDIT: I stand corrected. Read jlicrx's post below. Just goes to show you can't believe everything you read on the net... even if the source seems credible.

    I am sure you can, but since it was originally designed for a halfshaft, and as you pointed out would drive like ass, what would be the point? Or just a little FYI?

    you cannot use the D-series axles with the L3 ZC transmission - the inner CV joints on the D-series are too small - put them in the transmission, they will just spin around - that is why you have to use the 90-93 Integra B-series axles - if the mod said that they will work, then assume he doesn't know what he is talking about - we have a shop specializing in ZC swaps and trust me D-series axles will not fit the L3 ZC transmission

    I like mine. :)

    Too bad I'll be tearing it apart soon and playing around inside. Baby ITR transmission anyone? :lol:
